Help recovering from old wallet.dat for an old friend.
Hey all, I've been in the Bitcoin space since early 2012. I have a situation that I would love to get some assistance with, I will explain the situation momentarily. Please do not message me and ask me for the wallet.dat file it's not going to happen. TL;DR I have an old wallet.dat file from late 2012 or early 2013 from a coin I sold to a friend. Tried to recover the coins in 2018 and failed, later found out that someone had access to the computer and could have easily stole them. Would the current Bitcoin Core be able to read an old wallet.dat file, and is there any way to easily view the balance of a 2012 wallet.dat file without having to load the entire blockchain? In the early days of Bitcoin as many of you OG's know, the only option to securely store your coins was to use the default Bitcoin wallet in a wallet.dat file. A friend of mine was really wanted to invest in Bitcoin but didn't know how, so I sold one to him because I didn't want him to get screwed. I installed Bitcoin QT on their home laptop, had him write down the password on a piece of paper and had him put a backup of the wallet.dat file onto a USB. Fast forward to when the price went to $20k plus, he calls me up super excited and said he wanted to sell his coin because he could use the money and I encouraged it because from my prior experience I knew the momentum was unsustainable and I had sold a few coins of my own. Anyway, I go over to his house and we huddle around his computer. He tells me that he upgraded the hard drive in his computer and gave me his old one and I went back to my house to get an external hard drive reader. I came back, booted up his old drive and remembered that we would have to let it sync up in order to get the coins out, and on his internet that wasn't going to happen anytime soon. He gave me the hard drive and I went home and left on Bitcoin QT overnight and in the morning I was shocked to see that there were no transactions on the wallet. Quick note, he had the wallet password in a file on his documents titled "Bitcoin Wallet Password.txt". smh. I started to panic, and I realized how bad this looked on me. I called him and told him that there were no coins on there and asked if he had his USB stick and he told me he had lost it years ago. I frantically looked through all of my old wallet files to find any transaction that could link to his address, to show that his coins were still in there. After a while I realized I had sent the coins from the now defunct btc-e.com, and had no way to check up on the coins. I did everything in my ability to try to recover lost data from the hard drive to no avail. I asked him if anyone else has had access to his computer, and then asked him how he replaced his hard drive because I know him well enough to know he wouldn't pull apart a laptop to replace the hard drive. He told me he took it to a shop to have it replaced a few months earlier. I suspect that I'm either trying to view the wallet incorrectly or whoever replaced his hard drive snooped on his hard drive, stole the coins and replaced the wallet.dat file and generated a new one. I have to admit, I was relieved a little bit to have an explanation to coins not being there but I could imagine he thinks I may have had something to do with it. I made a few more attempts over the years whenever I was reminded of the situation to no avail. We kind of fell out after that and haven't spoken in a while. Recently, I saw a post on his Facebook that his wife is pregnant they are having a baby, and that's why I'm here. I would love nothing more than to be able to message him and let him know that I have 11 grand waiting for him, because I'm certain the money would mean the world to him during such a stressful time. Any help or insights would be incredibly helpful and appreciated.
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/22.214.171.124 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types
The ability for developers to remove polls and votes

The last month in the world of Mousecoin has been HUGE! There have been many changes, the addition of new awesome ways to earn MIC3 including ourFaucetspage and thePhoneumGames. We have also seen the launch of ourCommunity Membership, which entitles each registered user to receive up to 200,000 MIC3 per month. We hope you are all keeping safe and are happy to provide you with our Mousecoin Network May 2020 Report.
MOUSECOIN IN GAMES!!
FINALLY, after months of negotiation and with the help ofPhoneum, Mousecoin has partnered withPhoneumto be included in two of the most popularPhoneumcrypto games currently available.We have added a newGamespage, whiche features all the information and link for the games, with more to come.Here is the run down:
📷 Crypto Treasures is a game, where players complete various quests, trivia and mini games to unlock Gold (in-game currency), Treasure Chests, Items, Collectibles, and various Crypto currencies, including the featured Mousecoin (MIC3).
📷 Visit a new type of planet, one that allows you to earn real cryptocurrencies while playing a beautiful and futuristic game. The main objective is to extract the valuable resources of the planet: Crystals. There is a special machine designed specifically to dig up the Crystals automatically and deliver them to you. All you have to do is activate the Digger and after 4 hours, it will have the resources ready to be claimed.
Earn up to 200,000 MIC3 Per Month!
At the beginning of last month we began establishing ourCommunity Membershipwhich offers all registered Mousecoin Members a share of the rewards earned from theCommunity Fundjust for being a member and following Mousecoin on all of oursocial media.As we come to the end of the first month we are currently in the process of checking all registrations and working out payments. We have also updated the profile page to include a Member News tab, Verified Notifications for each Social Media and a Monthly Payment History section. We are currently working on verifying all accounts registered before 1/6/2020, and should have all of these processed in the next few days, with all payment going out before the end of the week.
Become a part of the Mousecoin (MIC3) Community.Membership is FREE and it comes with HUGE bonuses!!
Just a reminder for the community and also for any new members, we have added aWallet Setup Guidespage, which takes any first time user of Mousecoin step-by-step through the process of installing their Mousecoin wallet and getting it online. The guide uses the latestblockchain snapshotfound on theWallet DownloadsPage in the example explanation meaning that all new members of the Mousecoin community will be able to get their wallets online faster as the sync time should be minimal. We will be updating theblockchain snapshotat least once every month to ensure that people have access to the most up to date blockchain info. The latestblockchain snapshotwas performed on the 1st June 2020. The wallet version is currenty V188.8.131.52, with future releases of the Mousecoin wallet coming soon If you are new to crypto currency or just after a bit of guidance setting up the Mousecoin wallet, check out ourWallet Setup Guides 📷Windows 📷Raspberry Pi 📷Wallet & Blockchain Snapshot Download (UPDATED 01-06-2020)
POS & STAKING
In the last month we asked the community if they would be interested in being a part of a Community Staking Pool. After investigations into this finding security flaws in most platforms, as well as the lack of interest from members of the community we have decided to not go ahead with the Community Staking Pool. While we understand that there are members of the Mousecoin Community that are unable to stake themselves for whatever reason, and that there are a number of staking platforms that offer pool staking for MIC3 to help these people stake, we will not officially be supporting any staking platforms.We ask all Community members using these or thinking about using these to keep in mind that any MIC3 hosted on these platforms is not in their wallets, and therefore not controlled by them. Do proper investigations into any platform that you use for this as there is always the possibility of loss. We encourage all members of the Mousecoin Community to stake from their own wallet (where possible) as this helps us to secure the network. If you need help setting up your wallet, go to ourWallet Setup Guidespage for step-by-step guides on setting up your Mousecoin wallet.
We have updated the Mousecoin (MIC3)FaucetsPage: To make things clearer and we will be adding more faucets soon!
Last month we saw the edition of theUSDT/MIC3pair tonanu exchange. In our efforts to increase exposure of Mousecoin, we are still attempting to list on bothATAIXandUnnamed.Exhchange. ATAIXWe have risen to 18th position in the voting list onATAIX, but we still need your votes. Remember you can vote every 24 hours for this listing, and you can share in 125,000,000 MIC3 📷 Unnamed.ExhchangeThe exchange listing forUnnamed.Exhchangeis 0.05 BTC.For anyone unfamiliar with the exchange there are two ways that you can donate to the listing: 1. If you are already a member of, or wish to be a member ofUnnamed.Exhchange(and why wouldn’t you), you can put funds towards our listing by tipping us through the trollbox (Mousecoins). If you wish to be a member ofUnnamed.Exhchange, you can register here:https://www.unnamed.exchange/Login/Register 2. You can also donate to the listing fee through the following addresses:BTC – bc1qmaqzhfqcw0urva0rtgfz5qvq4rw7kdnp6j7754LTC – ltc1qc775eeftdde2jrevnyukrd2w9853jy5gmtv6rnDOGE – DEnBpriaFnKiNeBv6Q7MVxMg5hLv5urQFgUTIP – AUTyu2JhGAaCkM3KAmeBopto2bNBchNJfE If you would like to donate in another crypto available onUnnamed.Exhchange, we have opened up the chat on the Discord channelHEREto assist with this. Please request the address and we will provide it for you.ANY AND ALL DONATIONS ARE WELCOME!!This is a good exchange and getting a listing her should help lift the profile of MIC3. We will be reporting balances to the discord channelhttps://discord.gg/cYuA8FA
📷 In the last month theCommunity Fundhas undergone a huge amount of change. We have completely moved all of our remaining balances away from 4Stake, with the MIC3 going to theCommunity FundMIC3 account and the remaining crypto’s towards out listing onUnnamed.Exhchange. TheCommunity Fundpage on the website has also been updated to reflect all of the changes.It is an exciting time for theCommunity Fundas we have now reached a balance that will sustain itself. This is why we have introduced the Community Member payment, and are able to sustain the faucets we have onhttps://erex.io/freecoin/and in thePhoneumGames. There is still more to come! 📷
HELP! OverflowError: timestamp out of range for platform time_t
Hi, I am guessing this means Electrum Wallet is set to a particular time zone, which is not allowing me to send bitcoin. As I tried to send to the exchange and found this error popped up. This is my first time using the wallet and I have no idea how to change the time to sync. Anyone have an idea what I can do to change it(thats is it is the time issue) so I can send to exchange.

The core developers are pleased to present the 184.108.40.206 Elizabeth milestone leisure release. This is a leisure release primarily aimed at non-mandatory items and bug fixes leading up to the Fern mandatory milestone release. This release also enables us to whitelist teams other than Gridcoin as a stepping stone for the implementation of no team requirement in Fern. Enjoy! https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/220.127.116.11 Changelog...
Add freedesktop.org desktop file and icon set #1438 (@a123b)
Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v18.104.22.168-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
Beginners guide to Syscoin (SYS) and why you should be investing in this cryptocurrency in 2018
What is Syscoin?
Some have described Syscoin(SYS) as the Shopify, Amazon and Ebay of the blockchain world. Syscoin is a revolutionary cryptocurrency that offers near zero cost financial transactions, incredible speed and provides businesses the infrastructure to trade goods, assets, digital certificates and data securely. Syscoin isn’t just about money and trading, it has the ability to attract various business types thanks to its native set of features geared towards business on the blockchain. From eBay traders and High Street shops to Medical applications, Insurance and Gaming, Syscoin’s decentralized network benefits everyone! Syscoin is developed by Blockchain Foundry (BF). BF provides blockchain technology based services, projects and products for a wide variety of use cases with the stated aim of disrupting markets by leveraging the potential of blockchain technology. Syscoin is mainly known to be the first cryptocurrency to offer a fully decentralized marketplace based on blockchain. What is lesser known is that this is only a part of what Syscoin offers. With the introduction of Masternodes in February or March 2018 SYS will be transformed from just a ’marketplace coin’ to a completely ‘utilitarian coin’. The Masternode infrastructure allows the addition of decentralized databases and file storage, increased transaction speed to surpass POS/Visa/Mastercard capabilities, true Turing complete smart contract capabilities for unlimited business logic, sidechains, application layers and an identity layer. This will all be accessible through an API, rather than a new language, enabling nearly any developer to create any blockchain application they can conceive. This will usher in the next generation of blockchain applications - made for new or existing businesses - by conveniently offering everything available from the blockchain space today.
The blockchain as conceptualized by Satoshi Nakamoto back in 2008 envisioned a peer-to-peer electronic cash network that would prevent double-spending. A year later, the blockchain became an integral part of bitcoin, serving as the latter's public ledger of transactions. Although Nakamoto's reference client mentioned a decentralized marketplace service, the subsequent implementation did not incorporate this due to a lack of resources. Syscoin was initially described in a 2014 draft whitepaper that envisioned Decentralized Marketplace Creation, Decentralized Smart Contracts and Documents, Decentralized Certificate Issuance and Transfer, and Decentralized Data Storage and Retrieval, as among the services that it would offer upon its release. Syscoin aimed to bring Nakamoto's vision of a decentralized marketplace back into the blockchain, among the other commercial-grade services it aims to deliver to clients. Other services that Syscoin plans to provide include secure data storage and transfer, and unique user aliases that link their owners to the services controlled by the alias. The early Syscoin wallet was superseded by the release of Blockmarket Desktop 1.0 on September 12, 2017, marking the culmination of Syscoin's vision of a fully decentralized marketplace with a desktop GUI based on the blockchain. The planned release of Blockmarket Web, a fully web-based version, and Blockmarket Professional in 2018 takes that vision one step further, as more advanced seller stores become a reality.
The Team that NEVER quits! Before the launch of Syscoin (Q3 2014), there was a presale ICO by Moolah (as a partner), which turned out to be detrimental for Syscoin. The project raised around 1,000BTC for development but the Syscoin Team only managed to access 250BTC which were used for price support. Moolah (Ryan Kennedy) absconded with the bulk of the ICO funds and the Syscoin team were left with ~30million Syscoin at a price around 400 satoshi. Even after this tragic event, the devs didn’t quit and continued to work on the project without stopping. The case against Moolah is still on-going. See the article from CoinDesk here: http://www.coindesk.com/uk-court-syscoin-injunction-moolah-750-btc/. What is this detail telling us about the dev team? While some crypto projects are just scams and bring little to no innovation, they’ve proven that they are in it for the long term - ably demonstrated by the fact that they continued to work despite their funds being stolen. And now that hard work is beginning to pay off with the entire team going full-time for the first time in January 2018 and new developers being hired following VC funding for BF.
Building on the World's First Decentralized Marketplace, Blockmarket is the newest generation of Syscoin's Desktop wallet with a complete, state-of-the-art marketplace built-in where you can securely and reliably buy and sell any items you wish. Entire stores can be created directly through the marketplace where you can sell your own products or re-sell others’ products for commission. Use of blockchain technology eliminates middlemen, credit card fees, maintenance fees, downtime and political interference. Persons are literally able to buy or sell anything to anyone, anytime, anywhere on Earth! Blockmarket Desktop was launched on September 12, 2017.
Key Blockmarket Features
Decentralized Marketplace The marketplace platform provides a decentralized and high redundant channel for selling goods and services. Features include:
• Price Pegging to currencies such as USD, EUR, GBP, CAD, CNY and BTC • Bitcoin and Zcash as payment options • Arbitrated Escrow • Encrypted Messaging • KYC/AML Compliance • Images • Unlimited Inventory Items
Wallet addresses for cryptocurrencies generally consist of a unique string of between 27-34 alphanumeric characters. Such an address isn’t easy to memorize. Although the addresses can be added to an address book within the wallet, Syscoin has taken the user's convenience one step further, allowing you to create a unique Alias for your wallet address, such as a name, title, or characters specific to a username. These can be used to send SYS from home, to a mobile wallet, to work, to friends, to common suppliers or to repeat customers easily, without requiring any memorizing, writing it down, copy & pasting or emailing yourself the address.
Using the cryptography of the blockchain persons can issue, authorize, and exchange digital certificates of any kind. With Syscoin anyone can issue provably-unique certificates with text or ASCII content to one or multiple parties on the Syscoin blockchain. These certificates can be authenticated by anyone via Syscoin’s cryptographic proof of work. This allows for the creation and free exchange of any kind of digital asset such as ownership certificates, warranties, receipts, tickets, certifications, diplomas, software licenses and more.
Integrated Crypto exchanges - Flypme and Changelly will facilitate exchanging 30+ cryptos for SYS, directly within the Blockmarket wallet.
BM web will bring SYS’s existing decentralized marketplace and all its features into a web-based version, enabling ease of use with a simple email and password login (grandma friendly) without any need for downloading a wallet or waiting for sync. Blockmarket web will be launched in February 2018.
Ability for world-class transactions-per-second performance to scale-out with added nodes (theoretically 100k TPS per 1000 Masternodes, 300k TPS/3k masternodes, etc). In later releases, masternodes will also process smart contracts and facilitate sharded+encrypted offchain file-storage (with onchain anchors), among other touted functionality. They should also result in steadying the price movements - less volatility as holding will be incentivized
Scalable Ethereum Virtual Machine: Allows Turing complete smart contracts to be executed following the ethereum protocol at a much faster speed and at a fraction of the ethereum gas price.
Assets & Token Issuance
With its token issuance service, Syscoin allows anyone to create a custom asset token which can then be sent directly to anyone else on the network. This facilitates a variety of use cases including ICO token issuance, supply chain management, reward points, and loyalty programs.
Anonymous transactions: via mixing/shuffling at user-specified denomination. Afterwards, additional tech will be added in the near future which will further compound the degree of anonymity provided -Add ValueShuffle running on top of the masternode layer and you have the world's most advanced privacy tech in any coin. This brings true money fungibility to Syscoin and the missing link for true economic sovereignty. https://twitter.com/realSidhuJag/status/948588279540035584
Transactions can be sent and received instantly. This represents a similar sending capability as Dash, but is a step beyond- A type of backend node locking will allow an instantly received sum to be sent immediately, without delay, and without network risk of double-spend.
Because cold wallets, such as those stored offline in a text file as I keep recommending in my standard advice below: All you need is a text file to put your wallets in, like this example from https://walletgenerator.net/?currency=Dogecoin 1,"D7WBUpdgLRtG6WyPsqjhaKiJR65X8ZGnkZ","6KieLMW1poAzNVnmLuQZqA262gxEQ51eLGdDK8e2GL2B4LHCKKb"2,"DM8LT16d49zHr8ByXbUwZb9UBXDGMaZRdc","6Ktgxdv6vN9v2bDHwcJBBb3oMRAgXJumESzBnxaXUSGFZoq6pWQ"3,"D5UCa51AfxjtVHQ46oYXe2YfkctTeLXPhx","6L2WSPWadRYCwt2L1CxH6zC7PoTYY3KyjxdiUoCqi5eyq6hQKvj" Use https://coinb.in/#settings to move coins. Download both sites and run them offline. Use https://bitinfocharts.com/dogecoin/ to check balances and transactions. See http://www.mocacinno.com/blog/create-sign-broadcast-transactions-using-coinb/ for coinb.in tutorial. And read the ELI5s (and my history) for more info. Are without doubt THE SAFEST way to store your coins. Plus, they consume no resources. No bandwidth, no network stress for every node we have, no storage of 20Gb+ blockchains, no weeks of waiting for things to sync, no tearing your hair out and posting desperate pleas for help, and most importantly, no coins irretrievably lost because you or your client screwed up.
Wallets, ALL WALLETS are nothing but numbers. Very large numbers, but fundamentally no different from “7”, “42”, “911” or a phone number. They cannot be created nor destroyed, and you either know them or you don’t. Anyone who knows a key can use it to spend any coins it controls. Anyone who doesn’t know it, can’t. Don’t be the guy who doesn’t know his own keys. Keep them safe. Make copies. Keep those safe. Don’t let your friends, kid brother or random burglar find them, but don’t lose them either. The only other thing you need for a fully functional wallet is a way to spend coins. Coinb.in is such a way. There are others, such as DogeCoinMultiSig.org which tomcarbon built. Oh, and you can and should download it and run it locally.
The default entry point for coinb.in is https://coinb.in/#settings because this settings page is very well hidden. Its in the tiny gear wheel on the Broadcast page. Looking across the top of the page, you can see
We’re only going to use three of these. New, Sign, Broadcast. Now, keep in mind that coinb.in is an old Bitcoin tool which tomcarbon added Dogecoin to. Sometimes it thinks its dealing with Bitcoin still, so if you see anything odd, go and make sure you’ve selected Dogecoin in the Settings page.
This tool should be the only place you spend coins. Sure, some clients may look more convenient, but they all suffer from a very big coin-losing flaw. Whenever you split a UTXO, they create a new wallet to send the change to. And they DON’T TELL YOU! This means unless you back up after every transaction, you run a high risk of finding all your coins have ‘disappeared’ from your wallet, and you don’t recognise where they went. So if you use a client for the convenience as well as a text list of your wallets, you won’t know to add a new wallet to your masterfile. Its best to ditch the clients entirely.
Now we come to the nitty-gritty. Lets use those three wallets above and assume that #1 is the source, #2 the destination and #3 the change wallet. Note that these won’t actually work, as none of them have ever been used, but they will do as examples. New Transaction Located at the bottom of the New menu, this will give you a page to enter your wallets and amounts. In the top field, you enter your source address or Key. If you use the key, it will calculate the address when you click the Load button, which should match what you expected. Note that Load only brings in the first 100 UTXOs. This is so that you can retrieve coins from high-volume wallets which would kill any client. Coinb.in is in fact the ONLY WAY to do this, as even QT falls over around 600 UTXOs. You will see the total balance that was loaded in the Transaction Fee field. And also in the Inputs tab, where you can go to adjust which UTXOs to spend. Now you need to add the wallet(s) and amounts to send to them. Lets suppose the source contained a single UTXO for 1,000 Doge. You want to send 500 of them. So you would enter the #2 address in the Address field, and 500 in the Amount field. The Fee now changes to 500, which is not what you want. So you click the + button to bring up a new line, enter the change address and the other 500, making the fee zero. And you’re done. Check that the Fee is indeed zero. Check that the amounts shown in the Outputs and Inputs tabs match exactly.
THIS IS CRITICAL!
There is a bug which will send all the coins to the miners if the Outputs exceed the Inputs. I would have expected the Fee to show as negative in such a situation, but it doesn’t. BE WARNED! Once everything looks right, hit the Submit button. This will give you a block of hex code. Copy it. Sign Go to the Sign tab and paste it. Add your private key for the source wallet and click Submit. Note this can be done offline for safety. This will give you another block of hex, the SIGNED transaction. Broadcast Copy this and paste it in the Broadcast tab and click Submit. That’s it. Your coins are on their way. Make a cuppa and settle in while they arrive in a minute or three. Note: All fields retain their values unless you refresh the page! This can be a boon when doing multiple transactions, such as when emptying a huge wallet. But it can also be a trap for the unsuspecting. Refresh or close the window when you’re done.
Who should use this? Absolutely EVERYONE! Even if you’re wedded to your client in some satanic blood-contract, you should still know how this works, because sooner or later you’re going to have a problem you can’t fix without it. Definitely download the site and store it on every device you have. On every USB backup of your wallets. On your phone (well, except iOS which doesn’t do local HTML), etc, etc, etc. Oh, and if you’re a programmer SmartyShibe, do consider improving the code over on GitHub.

[PSA] Dogecoin Wallet version 1.4 released. You must update.
WARNING: DO NOT send your wallet.dat file or dogecoin folder to anyone. There have been reports of people offering to help others by asking them to send their files to them so they can help. DO NOT do this. Scam attempt picture Always encrypt your wallet! I can't express this enough. You should use a strong password longer than 15 characters. This password should contain numbers, symbols, and some capitalization! There is no need to have your wallet open 24 hours a day. Open it only when you need it. See - 'Getting Started' on the side bar. This entire post has been written to be as close to ELI5 (Explain it like I'm 5) as possible - By request! If anyone wants to add/fix/correct anything in this message, please send a message to the mods <<-- Click blue text. All blue text in this post can be clicked on. The blue text is a link to a picture, site or download file. A very important message/reminder below. 25 Jan 1.5 pre-releases have started. http://www.reddit.com/dogecoin/comments/1uhpwf/dogecoin_for_mac_14_topic_thread/ OLD VERSIONS The 1.4 update for the dogecoin wallet has been released. This update addresses the block chain error that occurred. This update is mandatory meaning you have to do this update. Also further down the page you can read up about the block chain. You MUST make sure you're on the correct block chain and the old block chain has been removed. For a Windows computer the version must be 1.4. - 1.4.1 just released! See below For a Apple Mac Computer the version must be 1.4 Download links: [Windows Download Link](https://github.com/dogecoin/dogecoin/releases/download/1.4/dogecoin-qt-v14-Win.zip) <<--Click to start download Windows Download Link 1.4.1 UPDATED 19JAN Mac Download Link <<--Click to start download Mac users can join this thread if there are any problems Android (phone): Please see This post To update, simply download the new version from the download link above. Open the downloaded file and extract the contents of the downloaded file into any new folder or location on your computer. If you put the files into a folder you can name the folder anything you want but make sure you remember that this is the latest version of the software. You don't have to remove your folder containing the old version of the wallet. You can place it in a folder called 'Old versions of dogecoin wallet' if you like. Now you can click on the Dogecoin icon contained in the new folder to open your version 1.4 wallet. What happens if I get an error when I open the new wallet? An error was reported called "11DbException" If this happens Download this file and place it in the same folder as your updated wallet. Open the file you just downloaded called "Dogecoin OPEN' and wait. This might take 2 or 3 minutes. Also jtlarousse has found a solution that worked on Windows. Please follow carefully and make backups before starting. Reebzy might have found a solution for Apple Mac Blockchain fork 101: The block chain is a ledger or document created containing every transaction that has ever happened. This file can be quite large. Bitcoins ledger is over 15GB. At some point this document/ledger split into two separate documents known as a fork. How do I know if I am on the right block chain? Go to your newly updated dogecoin wallet and open it. Click on Help>>Debug next Observe the current block number *Notetheexamplenumbersinthepicturesmightbeoutofdatebythetimeyoureadthem Now go over to http://dogechain.info/chain/Dogecoin . This website is the official Dogecoin blockchain website. Check the block number they're reporting The number you found in your wallet and the number reported on the website should close. There might be a difference of 100 blocks depending on when you last refreshed your wallet or how long it took for you to get from one step to the next step in this guide and if the dogechain website is lagging. I'M NOT ON THE CORRECT BLOCK CHAIN My numbers are very different. How do I get back onto the right block chain? IMPORTANT For windows: 1)Close down the Dogecoin wallet client. 2)Go to your data folder: C:\Users[your windows log-in name]\AppData\Roaming\DogeCoin 3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file! 4)Download this update file and place it into the Dogecoin folder where the other file was deleted. For Apple Mac: 1)Close down the Dogecoin wallet client. 2)Go to your data folder: ~/Libarary/Application Support/Dogecoin 3)Delete the Dogecoin.conf file. Do not delete the wallet.dat file! 4)Download this update file and place it into the Dogecoin folder where the other file was deleted. Next visit this post by Netcodepool for instructions on how to manually download the correct block chain and install it.
Edit: Some posts were removed from this thread. To limit confusion. Check this post for details about mining pools that were/are using the wrong fork. Did you send coins only to find out you're on the wrong chain? See this post to get them back An Apple Mac support thread has been made by voidref (The mac developer). If you're having troubles please see this thread Some shibes have reported their wallets wont sync. Please check to make sure your firewall, antivirus, malware scanner or similar programs are not blocking it the wallet. You can add rules to these programs to allow the wallet to make contact with the internet. It's not advised but possible to also disable the software for a short amount of time. Don't forget to enable the software again afterwards. Is your wallet crashing? Try this helpful tip from gandhikahn or if you're using windows try the 1.4.1 update above.
Much bad news. THE DOGECOIN BLOCK CHAIN HAS FORKED. This is a bad thing.
ELI5: Your client is constantly downloading blocks and processing them, which is the way that Dogecoin works. Ten days ago, the developers made a change to the Dogecoin client that raised the limit of coins in a block from 500 million to 10 billion. So now some folks are running Dogecoin clients without that change, because they are older, and some folks are running newer clients. In block 42279, a transaction that broke the rule -- containing more than 500 million DOGE -- has prevented these older clients from advancing on the correct chain and they are now working on a bad ledger. If you are attempting to send transactions and you hit this behavior, you ARE adding transactions to the bad chain. There is a current risk of double spending and a lot of people are working on a bad ledger, both with mining and their personal clients. STOP sending DOGE (including pool payouts) until this situation is resolved by people that know more than I do. It might appear that you are still advancing past the bad block but your client might be going down the wrong fork! Details: My client is synced and fine, and I sent a transaction in the last few minutes, but I've heard from several friends that they are stuck on a prior block have forked off the main ledger after block 42279. Apparently, 10 days ago, there was a commit to the dogecoin client that raised the transaction limit from 500 million DOGE to 10 billion DOGE: https://github.com/dogecoin/dogecoin/commit/2ee5cb3396df66c10fef34480a183d00e3bec635 In block 42279 a 500m DOGE transaction was submitted which broke the block chain on clients older than that commit. I have heard from three separate folks now that their clients are stuck on block 42279 advancing on a separate Dogecoin chain. http://dogechain.info/tx/3119125a77e1bee6f0786af4e15a8eea3ba1b64081e121796b552637a76f2eb1 We have a blockchain split on our hands. Bitcoin went through one of these too. It's going to need intervention. What do I do?Stop sending DOGE and wait.I would also suggest waiting until the mining situation is sorted out, because there is a double-spend risk right now. You can view your client's current block in the Debug menu, under Help, for the Qt client.
UPDATE 4:48 AM UTC / 11:48 PM EST
I can now confirm three forks of the Dogecoin block chain exist, possibly more.
Deleting your blockchain and resyncing can land you on a bad fork again. Multiple reports of this happening.
Your best move right now is to get off the network and wait.
DO NOT SEND ANY DOGE until you are CONFIRMED on the correct fork, and even then, WAIT.
How do I know if I'm on the wrong fork?
In your client, open a debug window by going to Help > Debug.
Type getmininginfo and push Enter.
Compare the blocks and difficulty against the Dogechain.
Just to reiterate: if you resync your client you might end up on the bad fork again.
Developer intervention will be required to prevent this from occurring.
UPDATE 5:14 AM UTC / 12:14 AM EST
The network is responding. Between block 42475 and 42480 on the good chain, the network hash rate dropped from 20 GH/sec to 15 GH/sec and the difficulty dropped from 320.3 to 253.3. Here's my getmininginfo from 2 minutes ago:
My test client that I resynced as an experiment ended up on the bad fork. There's going to need to be an intervention here similar to Bitcoin's.
UPDATE 5:50 AM UTC / 12:50 AM EST
SCAMMERS ARE ATTEMPTING TO STEAL WALLETS IN THIS THREAD. IF YOU RECEIVE A MESSAGE LIKE THIS DO NOT COMPLY. DEVELOPERS WILL NOT PM YOU TO SEND THEM YOUR FILES. http://puu.sh/6a5jz/da27d4ae05.png
UPDATE 7:31 AM UTC / 2:31 AM EST
Okay, I'm done with this thread, folks. The Dogecoin developers are on it and the amount of abusive private messages that I'm receiving mean I'm washing my hands. Look for an official thread from developers next, the information is out and my role is done. Credit to hoopycat -- please tip him -- who discovered the source of the problem, I'm trying to get the word out right now. I do not get credit for this post.
There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition). That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)
EDIT 2017-01-09: Wallets WITHOUT Clients
Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin: Multi-Coin Wallet GeneratorNow supporting 129 currencies!Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos. Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.
EDIT 2016-11-23: SEMANTICS about MINING! :P
Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...
MINING IS DEAD!
MINING DOGECOIN IS UNPROFITABLE!
Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time. Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/ Oh, and most important:
READ BEFORE YOU POST!
At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess. OK, first things first.
A client is a piece of software you keep on your computer which holds one or more wallets. Here are the current client versions. If you're using an older client please upgrade to the newest version prior to sending/receiving coins. Backup! Backup! Backup your wallet.dat file or private key so you can import them into the latest version of the client.
Be warned that unless you’re running Core (aka QT), you could have issues with wallets containing lots of UTXOs (Unspent Transaction Outputs - Where your coins REALLY live). Go read the ELI5 below, and keep a close eye on your transaction counts. If you DO run Core, realise that all full clients, regardless of the coin, require a copy of the blockchain and must keep it up to date. This will cost you time, storage space and bandwidth. You can save a little by downloading the bootstrap file though. I haven’t checked how recent this one is, so let me know if you find a more current version.
OK, so next, grab this wallet generator. Even if you plan on running a client(s). Because a) it does many, many cryptocurrencies, and b) you WILL need wallets at some stage over and above what you keep in your clients. Just be sure to run it locally (and offline if you’re truly paranoid).
Oh, and here’s a simple way to keep track of all your wallets using HTML. You can grab the source and modify it, then upload it wherever you need to suit your needs. You will also want a separate file with your private keys, but don’t upload that one anywhere, because if you lose your keys or someone else gets access to them, you will lose your coins.
Next, be aware that there are online wallets available. While any wallet you don’t own the keys to isn’t actually yours, and therefore isn’t safe, the following are safer than most. Dogetipbot of course is used daily by shibes on Reddit. Block.io uses multisig and gives you Doge, BTC and LTC wallets as well as testnets, and Dogechain gives you your private keys (and also offers a wallet sweeping service).
Exchanges also offer wallets, of course. Not that you should use them to store your hard-earned coins, because they can and do get hacked with monotonous regularity. But at some stage you’re going to want to trade, or hold a few uncommon coins. You could do worse than these three:
And then there’s the obligatory question of mining. Put simply, mining is for all intents and purposes dead, and has been for a long time now. The costs are greater than any possible returns. But, if you insist on doing it anyway, maybe because you inherited a miner, you can earn about 0.01 LTC/day per MH/s merge-mining at Litecoinpool. That’s about 4 cents. :(
Shibes sometimes complain that the devs are not as active in /dogecoin as they used to be. You can find them on IRC, slack or their very own sub if you need them though. Or poke sporklin, who can often help.
You can of course ask any questions here, or post them in the sub. However, do try searching first, because I guarantee every possible question has been asked many times before. And you should also subscribe and hang out in /dogeducation occasionally. There’s much awesomeness there.
From peoplma I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere. Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge. And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core. From pts2002 Finally a proper sticky post! Here's some other stuff you could add: zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day shapeshift.io exchange - My favourite exchange, quick and easy. No registration required! Also, you should add some blockchain explorers! chain.so - Support for bitcoin, litecoin and doge. dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?) EDIT: Here's another thing I found! preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!
I want to stake Reddcoins on my Raspberry Pi, but there is no easy to install package for the Reddcoin Core client. I found some tutorials (mentioned at the bottom, under 'credits'), but I still struggled to get the result I wanted. It took some small adjustments, but I got the GUI Wallet of Reddcoin Core working on my Raspberry Pi Model 3B. See the steps below. :).
If you have any questions or comments, please post a comment in this thread, so others can also benefit from it.
If you would like to tip me: RqvdnNX5MTam855Y2Vudv7yVgtXdcYaQAW.
Even though Raspbian is the primary OS for the Raspberry Pi, it seems that it's not possible to build and compile the Reddcoin wallet software for Raspbian Stretch. However, I got the wallet compiled using Ubuntu MATE.
RPi: Raspberry Pi 3 Model B
OS: Ubuntu MATE 16.04.2 (Xenial)
Space needed: I would recommend at least 32 GB. I am using an 8 GB SD card for the OS, and a 128 GB USB drive for data.
The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 1 GB of 'virtual' memory by creating a swap file. After your Raspberry Pi has rebooted, open MATE Terminal again and enter the following commands:
sudo fallocate -l 1G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
To make sure the swap file persistent (so it survives a reboot), you have to add a line to the /etc/fstab file.
In MATE Terminal, enter the following command to open the file in Pluma (text editor): sudo pluma /etc/fstab
In Pluma, create a new line, add this text: /swapfile none swap sw 0 0 ↳ Screenshot (You should add spaces to vertically align the lines.)
Save and close the file.
Back to MATE Terminal; reboot your Pi: sudo reboot
To see if the swap file is used after a reboot, run: sudo cat /proc/swaps ↳ Screenshot
After the reboot, open MATE Terminal again. Download, unpack, configure, build and install Berkeley DB:
Add this line in Pluma: /uslocal/BerkeleyDB.4.8/lib/ ↳ Screenshot
Save and close the file.
Back in MATE Terminal: sudo ldconfig
Download the source of the Reddcoin wallet and build it:
git clone https://github.com/joroob/reddcoin
sudo ./configure --disable-tests
sudo make ↳ Screenshot (this will take some time; with me it took just over 1 hour)
sudo make install
Speed up synchronizing with the Reddcoin blockchain by bootstrapping.
cd (to make sure your working directory is your home directory)
Download the bootstrap file (1.45 GB): sudo wget https://github.com/reddcoin-project/reddcoin/releases/download/v22.214.171.124/bootstrap.dat.xz
Unpack the file: xz -d bootstrap.dat.xz
After a successful unpack, your will find the file ''bootstrap.dat'' in your home folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo $HOME/reddcoin/src/qt/reddcoin-qt
The welcome screen will appear and ask you about the data directory. I suggest a new directory in your home directory, I picked 'blockchain'. The directory will be created with all the necessary files. ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Use the file manager (Caja) to browse to your home directory and move the ''bootstrap.dat'' file to your data directory you selected in the previous step. Your home directory is the first item in the File Manager in the left menu.
The Reddit Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Launch the Reddcoin Core client again: sudo $HOME/reddcoin/src/qt/reddcoin-qt
Keep the client running until it's fully synchronized. This can take some time (it took 2 days for me).
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen!
Your wallet will be encrypted, and the Reddcoin Core client will be closed. Launch the Reddcore Client again. ↳ Screenshot 4
To stake, you need to unlock your wallet (by entering your password): Settings > Unlock Wallet...
Make sure "For staking only" is checked before clicking OK. ↳ Screenshot
You can only stake with Reddcoins that have matured: coins have to be at least 8 hours in your wallet to mature.
The grey arrow at the bottom should be green when staking. Hover over that icon to see the progress of staking. ↳ Screenshot
Backup your wallet! File > Backup wallet... ↳ Screenshot
Start Reddit on system login. Settings > Options ↳ Screenshot > This works when using only an SD card. > I can't get this to work when using SD card (for OS) and a USB (for data/blockchain).
Adjust minimization options, so you can safely press on the red X (close/exit button). ↳ Screenshot
The default browser, Firefox, stops working and crashes after updating Ubuntu MATE. My solution is installing another browser: Chromium. To install Chromium, enter the following in MATE Terminal: sudo apt-get install chromium-browser ↳ Screenshot You can then access Chromium via [Menu] Applications > Internet. ↳ Screenshot
To remote connect to the Raspberry Pi, I use VNC Connect from RealVNC.
Transcript of Open Developer Meeting in Discord - 5/31/2019
[Dev-Happy] Blondfrogs05/31/2019 Hey everyone. I have opened the channel. So us peeps can talk :smiley: Hans_Schmidt05/31/2019 Hello ! Tron05/31/2019 Hey all! I've been on different high-priority project for Medici for last few weeks, but that should wrap up Monday and then I can spend more time on Ravencoin. Thanks to Scotty for working on BlockBook which was needed for more wallets. Hans_Schmidt05/31/2019 Good opening. I was going to ask- The last ravend/qt develop Github commit was on May 3rd. Can anyone comment on when work is planned to resume on? Tron05/31/2019 @[Dev-Happy] Blondfrogs has been working tirelessly on Tags and Restricted Assets. It is coming along nicely. It is going to need lots of testing. Just because there's been lots of changes. [Dev-Happy] Blondfrogs05/31/2019 @Hans_Schmidt I have moved to my personal github with changes. You can check out my repo on the branch tags to view the latest commits Tron05/31/2019 Topic: 12-words and time One of the issues with 12-words on the mobile wallet is that it needs to scan the blockchain to find funds when recovering a wallet. One proposed idea is to include additional info (optional) like a number that represents the number of weeks since Jan 3, 2009 to start scanning the chain. Hans_Schmidt05/31/2019 @[Dev-Happy] Blondfrogs I looked at tags. tags last commit was 4/26. Is that correct? Tron05/31/2019 Another proposal would be to use some of the bits in the 128 bits of entropy generated as a number (instead of entropy). [Dev-Happy] Blondfrogs05/31/2019 yep. that is correct. I have been working on the Qt element of it, to hopefully aid with testing. Great idea @Tron Tron05/31/2019 Example: <96 bits entropy> + <32 bits timestamp> Or <128 bits entropy> which is the seed and encoded into 12-words, and then a number like 5212 for how many weeks after Jan 3, 2009 to start scanning the chain. This would just speed things up. Thoughts everyone? Thoughts anyone? [Dev-Happy] Blondfrogs05/31/2019 I love it. Link05/31/2019 It seems a good idea. ParabolicAssoil - HODL COACH05/31/2019 Pretty smart. I am wondering how Electrum handles it and why we can't use that method. I assume it doesn't work for assets? [Dev-Happy] Blondfrogs05/31/2019 Most Electrum wallets are light wallets, and don't use the same syncing method that our breadcore wallet uses Tron05/31/2019 Electrum doesn't work for assets. Hans_Schmidt05/31/2019 Why does it have to be part of the word seed. Then you have to remember it like a key derivation path. Why not just have the gui ask at what date to start scan? Tron05/31/2019 Either method of encoding would work and be compatible with any BIP44. With the extra number, you'd ignore it for Coinomi, or JAXX. With the encoding the time into the 12 words, there'd be no change, but you'd lose 32 bits of entropy. 4 Billion times less secure if you knew exactly when the wallet was created. @Hans_Schmidt That's also an option. ParabolicAssoil - HODL COACH05/31/2019 Thanks for the answers, gentlemen Hans_Schmidt05/31/2019 The long term solution in bitcoin for faster more secure SPV is Neutrino protocol. Tron05/31/2019 What's Neutrino protocol? Hans_Schmidt05/31/2019 Complicated replacement for bloom filters but has some bitcoin-core pull requests already and being pushed by the Lightning folks. Tron05/31/2019 Thanks. I'll read about it this weekend. Hans_Schmidt05/31/2019 For what you need, a gui question is MUCH simpler [Dev-Happy] Blondfrogs05/31/2019 So @Tron for the 12 words there are two options we are talking about.
Using 12 words in addition to a timestamp to help the mobile wallets sync faster?
Using some about of words and a timestamp to create the private key?
Is this correct>? Both accomplish the same thing, just implemented in the different way. Faster sync for mobile wallets traysi05/31/2019 What's the status on messaging? [Dev-Happy] Blondfrogs05/31/2019 Messaging is complete, we are wrapping it up with the restricted assets release. I am currently buiding the QT gui elements needed for both restricted assets, and messaging. Tron05/31/2019 @[Dev-Happy] Blondfrogs Yes. They do the same thing. One option potentially reduces security of the 128-bit seed. The other requires writing down an extra number that is optional. 12-words + [optional number] Where the [optional number] just clues in the wallet as to when to start syncing the chain without it having to reference an API. [Dev-Happy] Blondfrogs05/31/2019 Thanks, If it was me, I would want to not change to many critical elements of the BIP44 protocol so that we can still utilize all current existing packages and libraries that support it. Hans_Schmidt05/31/2019 Mobile sync- Stay standard Messaging- From what I could tell, at protocol level Message and Memo are the same. Is that correct? [Dev-Happy] Blondfrogs05/31/2019 Yes. Tron05/31/2019 Message and memo are the same. The only difference is how the message/memo is interpreted by the clients. Hans_Schmidt05/31/2019 Thanks Tron05/31/2019 A memo that is attached to a tx that sends back to origin (for an owner token) is a message that will be displayed by clients. If the client has some of that token. Sminem05/31/2019 I just came here to say i love you all and keep it up. And also that we are all going to make it bruhs Hans_Schmidt05/31/2019 Makes sense 𝕿𝖍𝖊 𝕯𝖔𝖓 𝕳𝖆𝖗𝖎𝖘𝖙𝖔 CEO ∞05/31/2019 i got my barber to my some RVN i did my part Tron05/31/2019 @Hans_Schmidt Messages make sense or that Sminem loves us all? Sminem05/31/2019 both Hans_Schmidt05/31/2019 Yup:smiley: theking05/31/2019 I know there are a lot of moving parts right now, but what is the current ETA on restricted assets and tags going to testnet? [Dev-Happy] Blondfrogs05/31/2019 Currently the protocols are complete. However, to make testing easier for the average user, we are working on basic Qt functionality before we will release. I would say 1-2 weeks of development on the QT side, and we will be ready for testnet Sminem05/31/2019 What is situation with dividends, i'm dumb we had BW develop it but he cannot anymore due lack of time Tron05/31/2019 We will need to re-assign it or do it next. Sminem05/31/2019 sorry if it has been asked okey Tron05/31/2019 No, excellent question. [Dev-Happy] Blondfrogs05/31/2019 I have been working with a member of the community that has been implementing dividends. Sminem05/31/2019 nicee [Dev-Happy] Blondfrogs05/31/2019 I will have more info on that next week CryptokittyPizzaBoi JON.NETWORK05/31/2019 How is voting coming along? [Dev-Happy] Blondfrogs05/31/2019 voting was pushed back in order to work on restricted assets. So voting will be the next phase after testing of the latest build makes it to mainnet Chill05/31/2019 Just wanted to randomly add that you all rock! It can't be said enough theking05/31/2019 Awesome news on the timing @[Dev-Happy] Blondfrogs [Dev-Happy] Blondfrogs05/31/2019 yes sir :smiley: Any other questions we might be able to answer for you peeps? Hans_Schmidt05/31/2019 I haven't tried to test tags branch (restricted) on testnet because that would be another fork in a sea of forks. A pre-gui messaging+restricted "official" release would be helpful [Dev-Happy] Blondfrogs05/31/2019 Yeah, we can do that. I will work on that start this next week. and hopefully we can release testnet sooner. Hans_Schmidt05/31/2019 Great. Tron05/31/2019 Any tooling, or 2nd level stuff that's missing that is needed? [Dev-Happy] Blondfrogs05/31/2019 There are a couple things missing that will help view data but all protocols and consensus should be working and testable john mclaine05/31/2019 I just want to thank you, and tell you that my contribution will be to write an article in French detailing the entire RAVENCOIN project and its perspectives. IN CODE WE TRUST [Dev-Happy] Blondfrogs05/31/2019 sounds good @john mclaine I think we are going to call it for today everyone. Sneak in some questions if you have them in the next minute or so Tyrantt05/31/2019 Hey guys, I've been around since late Jan 2017 and just want to say that you guys rock. I haven't been following as much lately since I've been busy with life, but was wondering if there is a guesstimation on when the roadmap will be completed [Dev-Happy] Blondfrogs05/31/2019 Hopefully end of 2019. A nice little holiday miracle. Daveatt05/31/2019 would be a nice X-mas present indeed. Thanks guys for your hard work. You guys rock Tyrantt05/31/2019 Wow, that's sooner than I was anticipating. This is a great project and I'm glad that I took a leap of faith with it when I first heard about it. Keep up the good work :) [Dev-Happy] Blondfrogs05/31/2019 Thanks everyone. Have a great weekend and keep spreading the word of CAAAWWWWWWW We are out :smiley: Chill05/31/2019 Best dev team anywhere Sevvy (just wow)05/31/2019 :beers: Tron05/31/2019 Thanks all!!!
