having some issues with Electrum wallet on Ubuntu 20.04 LTS. i got it to install properly with no issues. but it seems like i am now have trouble connecting it to my node, below is what my .desktop file looks like # If you want Electrum to appear in a Linux app launcher ("start menu"), install this by doing: # sudo desktop-file-install electrum.desktop [Desktop Entry] Comment=Lightweight Bitcoin Client Exec=sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\"; electrum --oneserver --server localhost:50001:t %u" GenericName[en_US]=Bitcoin Wallet GenericName=Bitcoin Wallet Icon=electrum Name[en_US]=Electrum Bitcoin Wallet Name=Electrum Bitcoin Wallet Categories=Finance;Network; StartupNotify=true StartupWMClass=electrum Terminal=false Type=Application MimeType=x-scheme-handlebitcoin; Actions=Testnet; [Desktop Action Testnet] Exec=sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\"; electrum --testnet %u" Name=Testnet mode when opening up the wallet, i get the red dot on the bottom right hand corner, i can ping and access mynode via the local 192. address and i see electrum server is running. does it matter where the electrum.desktop file is located? as of right now i have it under /home/gp11/Downloads. is there anything else i can check? even if i remove electrum --oneserver --server localhost:50001:t i still get the same result with no connection, where i am thinking if i remove the line of code it should connect to other nodes. currently using myNode community Version 0.2.09 any help here would be appreciated - thanks in advance.
I have a problem uppgrading Electrum wallet on tails, despite following a guide.
Hi! I am following this guide https://blog.thestever.net/2019/02/26/upgrading-electrum-on-tails-to-3-3-4/ The first thing i do is log in as a administrator in tails by setting up a simple password. I also have a persistent storage with the following being saved Personal data, GnuPG, Bitcoin Client and Dotfiles. After adding and verifying the PGP-key i download the Appimage binary and the signature and Everything is fine. The first problem i encounter is when i put the followin in the terminal: sudo mkdir -p /live/persistence/TailsData_unlocked/dotfiles/.local/share/applications sudo chown -R 1000:1000 /live/persistence/TailsData_unlocked/dotfiles/ mkdir -p /home/amnesia/Persistent/bin/ mkdir -p /home/amnesia/Persistent/conf/electrum/ the sudo command asks for a password( administator) and gives me a "wrong password" Before i print anything. I somehow get passed this. The next big issue is when i am supposed to save a specifik command into gedit. After pressing save i get the following error message. " Could not save the file /live/persistence/TailsD...ications/electrum.desktop Sevral people have complained about this and other things in the comments if the guide. Please help if you can. tldr: Getting stuck on saving the following text in a gedit: [Desktop Entry] Comment=Lightweight Bitcoin Client Exec=/home/amnesia/Persistent/bin/electrum.AppImage -D /home/amnesia/Persistent/conf/electrum/ GenericName[en_US]=Bitcoin Wallet GenericName=Bitcoin Wallet Icon=electrum Name[en_US]=Electrum Bitcoin Wallet Name=Electrum Bitcoin Wallet Categories=Finance;Network; StartupNotify=false Terminal=false Type=Application MimeType=x-scheme-handlebitcoin; Actions=Testnet; error message: Could not save the file /live/persistence/TailsD...ications/electrum.desktop
I need some help. Installation went fine and everything, but I have issues launching electrum from the menu or krunner. Apparantly these shortcuts are meant to execute /usshare/applications/electrum.desktop This is what the file says:
If you want Electrum to appear in a Linux app launcher ("start menu"), install this by doing: sudo desktop-file-install electrum.desktop [Desktop Entry] Comment=Lightweight Bitcoin Client Exec=sh -c "PATH=\"\$HOME/.local/bin:\$PATH\" electrum %u" GenericName[en_US]=Bitcoin Wallet GenericName=Bitcoin Wallet Icon=electrum Name[en_US]=Electrum Bitcoin Wallet Name=Electrum Bitcoin Wallet Categories=Finance;Network; StartupNotify=false Terminal=false Type=Application MimeType=x-scheme-handlebitcoin; Actions=Testnet; X-Desktop-File-Install-Version=0.22 [Desktop Action Testnet] Exec=sh -c "PATH=\"\$HOME/.local/bin:\$PATH\" electrum --testnet %u" Name=Testnet mode
Launching electrum from terminal by simply running "electrum" works flawlessly though, so I guess there must be an issue with shortcut linking somewhere. I'd appreciate if anyone had any ideas.
CashFusion makes Bitcoin Cash a privacy coin. It's already been used to fuse hundreds of thousands of BCH! Make sure to spin up Electron Cash 4.2.0 today and get that liquidity flowing! (The more people using CashFusion at once, the more Fusions happen, and the larger your "anonymity set".) New to CashFusion? No problem, getting set up is EASY =) Just download the Electron Cash desktop wallet. It's got CashFusion built in! Set up your wallet (and be sure to write down your recovery phrase on a physical piece of paper, especially if you are going to hold significant amounts of coin in the wallet), then activate CashFusion by clicking the icon in the lower right: https://i.imgur.com/DXEPLtf.png Once it's activated, your wallet will start "fusing" the Bitcoin Cash it contains. Fusions happen over time as their own, separate transactions, and only cost you the network transactions fees (less than a penny). Each fusion transaction will include some of your coins*, so it will take multiple fusion transactions before all the coins in your wallet will be fused. (In the View menu, toggle the coins tab to see all of the coins in your wallet. In the "Label" field, fused coins will show CashFusion info.) Currently, Electron Cash keeps fusing your coins indefinitely. While it is on the roadmap to give you the option to stop fusing after some number of fusions per coin, there's no downside to leaving it to fuse continuously besides paying the transaction fees. (And every fusion gives you that much more privacy, while you are helping to provide "liquidity" for other fusers.) Also, EC does not yet prevent you from spending unfused coins, nor does it prefer fused coins when spending, so it's probably best to leave it fusing and keep your whole wallet fused, and/or pick your coins manually from the Coins tab. If you want that coin-management taken care of for your (and/or you're not comfortable picking coins to spend from the Coins tab), you can always switch back to CashShuffle for now in the Optional Features window, accessible from the Tools menu. Here's the CashFusion Telegram group where you are welcome to ask questions. (Just remember to be courteous!) Happy Fusing!! <3 *"Coins" are kind of a confusing concept when it comes to Bitcoin, but you can think of them just like discrete "bills" (or... "coins") in your wallet, but instead of coming in only certain sizes like $1, $5, $10, $20, etc, they can be any amount sent to you in a previous transaction, like 0.618 BCH, 0.000001 BCH, or 123.45679 BCH. (They can also be combined and split up. That happens in most transactions!)
https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/18.104.22.168 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

How to sell xBricks for money (self post for mod approval)
Preface I've written this guide with those that are unfamiliar with crypto in mind, however it's still a lengthy process. I'm going to try to present this in a way where you don't have to learn how the underlying crypto technology works, but I will add in links to relevant concepts in case you're curious. This process was a lot more complicated before but I made a web interface to simplify it. At the time of writing this, FortniteBR BRICKs are worth 10 cents a piece. That makes 1000 bricks worth 100 bucks. The liquidity pool is about $14,000 at the time of writing, meaning that there's room in the market for you to hypothetically get $7,000 if you had a lot of BRICKs. If at any point throughout this process you need help, DM me! Misc. Resources That Might Be Helpful
A phone or phone emulator (so that you can run the reddit mobile app and collect your BRICKs)
Step 1: Setup On your desktop computer, install MetaMask. This is an Ethereum Wallet which will allow you to interact with the Ethereum Network and its many sidechains. More on this later. Follow the setup instructions in MetaMask. If you've never done this before, you'll need to create a new seed phrase. Video tutorial if you get stuck. YOUR SEED PHRASE IS THE KEY TO YOUR WALLET. ANYONE WHO HAS ACCESS TO YOUR SEED PHRASE CAN TAKE YOUR FUNDS. IF YOU LOSE YOUR SEED PHRASE YOU HAVE NO WAY TO RECOVER YOUR FUNDS. WRITE IT DOWN AND STORE IT IN A SAFE PLACE!!! NEVER GIVE IT OUT TO ANYONE -ANYONETHAT ASKS FOR YOUR SEED PHRASE IS TRYING TO SCAM YOU! DON'T FALL FOR IT! In the MetaMask interface, you'll see "Main Ethereum Network". This process uses two networks. One of them is the Rinkeby Testnet (where the BRICK tokens are natively) and one of them is the xDAI network which is where we will bridge the tokens to in order to exchange them for Dai, a token which is pegged to the price of the dollar. From the dropdown, select Rinkeby Testnet. If you're in the assets tab, you should see a thing that shows your ETH balance. Below this, you should see an "add token" button. Click it. Go to "Custom Token" at the top. In "token contract address," paste in the following: 0xe0d8d7b8273de14e628d2f2a4a10f719f898450a The other fields will autofill. Hit next. You'll now see your BRICK balance (which will be 0, you haven't transferred your bricks yet) in MetaMask if you've done everything right. You'll need Rinkeby Ether to cover transaction fees. Since we're on a testnet, the Ether is worthless which means people hand it out for free. You can get this Ether from a variety of places:
Anyone who has Rinkeby Ether to spare: Make a comment below so that those who need it can ask you. Thanks :)
Now it's time to get your BRICKs from your Reddit vault into your MetaMask wallet. WARNING: ALL CRYPTO TRANSACTIONS ARE IRREVERSIBLE. Your Ethereum address shows up under Rinkeby. It should be "0x" followed by a bunch of hex characters. Click on it to copy it to your clipboard. You now need to somehow get this to your mobile device. Email it to yourself, text it to yourself, whatever. On your Reddit mobile app home screen, click on your profile icon and then go to vault. You'll need to set this up and claim your tokens if you haven't already. Be aware that this is also technically an Ethereum wallet. Keep your seed phrase safe. Send however many BRICKs you want to sell to your MetaMask wallet. Check to make sure the addresses are the same, but don't worry too much about making a typo or whatever. The chances that you'd make a typo that would result in a valid Ethereum address are slim, if you get a character wrong it'll just tell you it's not a real Ethereum address and prevent you from sending. It may show an error when you try to send. This is somewhat rare but pretty normal. They often run out of testnet Ether. Come back later and try again. If it works properly, it'll take about a minute to go through. It may take longer than that. Once the transaction goes through, you'll see that you have an absurd amount of BRICKs in MetaMask. No, there wasn't a glitch. The people who wrote the code for BRICKs made the decimals of precision weird for some reason. It's off by a factor of 1018. This isn't a big deal. If you see Bricks and Ether (ETH) in your MetaMask wallet, proceed to the next step. If you're having issues, feel free to DM me. Step 2: Getting Your BRICKs from Rinkeby to xDai There's a LOT going on under the hood for this part (deets for those interested). Previously this required manually generating contract interactions, which is kind of a pain if you're new to Ethereum. I made a UI to make this easier (it generates the transactions for you, all you have to do is sign them with your wallet). This took way longer to do than you might guess, so feel free to help a homie out at: 0x4BCcC2569DD93C7dF43431A7b70db569dedB6187 Go to my tool. Hit connect. If you're on the Rinkeby network, it should show your balance in BRICKs. Enter the amount you want to bridge (probably all of them). If neither of us have made any mistakes, it should pop up with a request to spend your BRICKs. If there's any issue with this tool, DM me. This allows the TokenBridge contract to take your BRICKs and put them on the xDai network where you can sell them. This is the part where you'll get an error if you don't have any testnet ETH. Set the gas price to 1 (the suggested price is based on the Main Ethereum Network - it's way too high). After you approve that, it'll give you another thing to accept. This is the actual transaction where it'll bridge to xDai. Again, make sure the gas price is set to 1 and confirm the transaction. Add xDai to MetaMask Switch to the xDai network. We're going to add another token. Again, go to "add token" > "custom token" > "token contract address". Paste in: 0x2f9ceBf5De3bc25E0643D0E66134E5bf5c48e191 If the transactions have gone through, you should see your xBricks (the name for BRICKs that have been bridged to xDai) in MetaMask. If not, wait a bit for the transactions to go through. Sometimes there are slowdowns that cause bridging to take a while. Shouldn't take too long, though. Once that's done, you're ready for the next step. Step 3: Trading Your xBricks for xDai Go to Honeyswap. Hit "select a token." You'll need to paste in the xBrick address again. Here it is: 0x2f9ceBf5De3bc25E0643D0E66134E5bf5c48e191 Click xBrick. You'll need to flipflop the trade around by hitting the arrow button. xBrick should be on top. Type in the amount of xBricks you want to sell, or hit max to sell all of them. 1 xDai = $1. You'll need to hit approve first. Set gas price to 1 again. Then you can complete the trade by hitting swap. After a bit, the xDai should show up in your wallet. Step 4: Mainnet Everything on Mainnet costs actual money to do. It costs about 50 cents to make a transaction and it costs about 3 bucks to use an exchange like the one we just used. If you don't have mainnet Ether, you won't be able to do anything with your mainnet Dai (what xDai is called when it's bridged back to the main Ethereum network). You may be able to find someone to lend you some ETH to make these transactions with. Whatever you do, just be aware. If you still want to bridge your xDai into Dai, go here and make sure xDai is on the left. If it's not, go in the top right and select xDai chain. Enter the amount of xDai you want to bridge to mainnet and then hit transfer. Follow the prompts. This part may take up to an hour due to recent network congestion. After it's done, if you go back to Main Ethereum Network in MetaMask you should see your Dai. If you have a few bucks of ETH, you can use UniSwap to convert your Dai to even more ETH.
