Let's connect with each others nodes!

Hey guys so I have my node up and running (finally). And I thought it would be cool to connect to those of you here who are running a full node as well.
If you want to add me just run:
bitcoin-cli addnode "24hhthvtdskpk4gw.onion:8333" "add"

Bitcoin core RPC very slow: "mapOrphan overflow, removed 1 tx"

I am running bitcoin core v0.18.0 and noticed that now my queries made locally through the RPC are taking very long. Here is my bitcoin.conf:
txindex=1 datadir=/media/**** maxmempool=30000 mempoolexpiry=99999 choosedatadir=1 checkblocks=3 minrelayfee=0 maxconnections=9999 debug=mempool debug=mempoolrej addnode=*** addnode=*** logips=1 rest=1 rpcuser=*** rpcpassword=*** 
And here is a sample of the log, notice the unusual mapOrphan overflow lines:

The node is up-to-date and I didn't detect anything unusual (like a stale block/fork).

Solve the "storage, mining pool and exchange centralization", and only generate 1G data every year(only pc-miner)

The blockheader has two segments with a total length of 64 bit0 (of which blocktime is 64 bits), which strongly prevents the collapse effect of the sha256 operation in the ASIC miner, so that the mining difficulty will not increase indefinitely. The centralization for the high hashrate of the mining pool is strongly restricted. Census and prune the transactions (at most 4 outputs per transaction) whose all outputs are spent,in the block below 1300 depth in batches(i.e. clear up the input and output at the same time, and only keep the version of all-outs-spent transaction on the disk,--not serialize vin and vout). 250 for each batch, 20 block files(one file per block) will be reconstructed for each block received from other nodes, that is to say, 5000 transactions will be pruned at a time. And special mechanism is used to make the synchronization of data from malicious nodes error free. Only 1G data is increased every year. The data it running for 1000 years will be no more than 1T. Block size is 2M, and only 1g data is increased every year without SPV, which strongly prevents the storage of a large number of block data reducing the number of nodes. At the same time, 'four outputs per tx' limit the settlement of the mining pool, and strongly prevent the centralization of the mining pool. For example, the settlement is sent to 4000 miners, which requires 1000 transactions. All currencies are locked in the maturity of 300 blocks (the input can only be used as prevout after 300 blocks), which strongly prevents the frequency of trading speculation, the crash from the online exchange, and prevent the centralization of the biggest online exchange in the world.
This has achieved "absolute decentralization".
At present, the tip height is only 600, and there is no pre-mined. The RPC is stable and reliable same as bitcoin 0.10.2. No segwit but P2SH, a little change based on 0.10.2. Usage: $ /download-directory/bitcoind -addnode =47.114.58.108 (same for Ubuntu) with bitcoin.conf configuration file

Running a Bitcoin node on a $11.99 SBC

Running a Bitcoin node on a $11.99 SBC
Just wanted to let you guys know that I'm successfully running a (pruned) Bitcoin node + TOR on a $11.99 single board computer (Rock Pi S).
The SBC contains a Rockchip RK3308 Quad A35 64bit processor, 512MB RAM, RJ45 Ethernet and USB2 port and I'm using a 64GB SDCard. It runs a version of Armbian (410MB free). There's a new version available that even gives you 480MB RAM, but I'm waiting for Bitcoin Core 0.19 before upgrading.
To speed things up I decided to run Bitcoin Core on a more powerful device to sync the whole blockchain to an external HDD. After that I made a copy and ran it in pruned mode to end up with the last 5GB of the blockchain. I copied the data to the SD card and ran it on the Rock Pi S. After verifying all blocks it runs very smoothly. Uptime at the moment is 15 days.
I guess you could run a full node as well if you put in a 512GB SDcard.
The Rock Pi S was sold out, but if anybody is interested, they started selling a new batch of Rock Pi S v1.2 from today.
Screenshot of resources being used
Bitcoin Core info
Around 1.5 GB is being transferred every day
---
Some links and a short How to for people that want to give it a try:
  1. This is the place where I bought the Rock Pi S.
  2. Here you find more information about Armbian on the Rock Pi S. Flash it to your SDCard. Follow these instructions.
  3. Disable ZRAM swap on Armbian. If you don't do this eventually Bitcoin Core will crash. nano /etc/default/armbian-zram-config ENABLED=false
  4. Enable SWAP on Armbian sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile sudo swapon --show sudo cp /etc/fstab /etc/fstab.bak echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
  5. Set up UFW Firewall sudo ufw default deny incoming sudo ufw default allow outgoing sudo ufw allow ssh # we want to allow ssh connections or else we won’t be able to login. sudo ufw allow 8333 # port 8333 is used for bitcoin nodes sudo ufw allow 9051 # port 9051 is used for tor sudo ufw logging on sudo ufw enable sudo ufw status
  6. Add user Satoshi so you don't run the Bitcoin Core as root sudo adduser satoshi --home /home/satoshi --disabled-login sudo passwd satoshi # change passwd sudo usermod -aG sudo satoshi # add user to sudo group
  7. Download (ARM64 version) and install Bitcoin Core Daemon
  8. Download and install TOR (optional). I followed two guides. This one and this one.
  9. Create a bitcoin.conf config file in the .bitcoin directory. Mine looks like this: daemon=1 prune=5000 dbcache=300 maxmempool=250 onlynet=onion proxy=127.0.0.1:9050 bind=127.0.0.1 #Add seed nodes seednode=wxvp2d4rspn7tqyu.onion seednode=bk5ejfe56xakvtkk.onion seednode=bpdlwholl7rnkrkw.onion seednode=hhiv5pnxenvbf4am.onion seednode=4iuf2zac6aq3ndrb.onion seednode=nkf5e6b7pl4jfd4a.onion seednode=xqzfakpeuvrobvpj.onion seednode=tsyvzsqwa2kkf6b2.onion #And/or add some nodes addnode=gyn2vguc35viks2b.onion addnode=kvd44sw7skb5folw.onion addnode=nkf5e6b7pl4jfd4a.onion addnode=yu7sezmixhmyljn4.onion addnode=3ffk7iumtx3cegbi.onion addnode=3nmbbakinewlgdln.onion addnode=4j77gihpokxu2kj4.onion addnode=5at7sq5nm76xijkd.onion addnode=77mx2jsxaoyesz2p.onion addnode=7g7j54btiaxhtsiy.onion ddnode=a6obdgzn67l7exu3.onion
  10. Start Bitcoin Daemon with the command bitcoind -listenonion
Please note that I'm not a professional. So if anything above is not 100% correct, let me know and I will change it, but this is my setup at the moment.

Addnode vs Connect

Addnode vs Connect
Hello everyone, i would like to share the differences between two commands (Addnode vs connect) which are used to find connections.
Addnode:
Let's you establish a connection to a particular node as well as let other nodes connected to it know you exist.
Connect:
Using this will only let you connect to that specific node and nothing else.

Recommended command if you're behind a firewall or have trouble finding connections. is addnode=xx.xx.xx.xx
x is the address of the node.Enter these node in the x42.conf file.
Popular nodes for x42
addnode=52.211.235.48:52342
addnode=18.179.72.204:52342
addnode=63.32.82.169:52342

Bitcoin core configuration in Windows

I've installed Bitcoin Core on Windows with the installer. I don't know how to increase the number of connections. Currently, it's always 8.
Several sources on the internet claim that custom configuration belong to a bitcoin.conf in the AppData/Bitcoin directory. But that doesn't work for me. I tried. In fact, I found out that the configuration including the datadir is currently contained in the registry. Not a single source I could found tells me that the registry contains these config values, so I'm kinda bummed out by this.
In any case, does that mean that I have to add a config value in the registry? And if so, how? The config names are different, namely, the registry config names are in camel case, while the names in bitcoin.conf are like "maxconnections=150". Help!
Edit: I consider the possibility that using the bitcoin.conf actually works and I made a mistake.
Edit2: Only 8 outgoing connections are possible (without addnode), so I opened the firewall as suggested.
Edit3: I finally get incoming connections. It's still slow but I'm optimistic that the speed will increase. It almost feels like synching an Ethereum node ffs.
Edit4: After having had 16 peers at some point yesterday, I'm back to 8 peers and no incoming connections. Speed is 1.3% per hour.
Edit5: I'm under the impression that I simply underestimated the size of the blockchain. I'm used to download huge files within minutes but 200gb is certainly something else. My bandwidth doesn't seem to be used to its full extent but it spikes up to the maximum throughput from time to time, so I guess this is the limiting factor after all. And some people want even larger blocks? F*** that.

No inbound connections on my bitcoin full node with TOR

update: it's ok now, it only required some time. Also, looking at debug.log it won't show anything about inbound connections as I thought, it must be used `bitcoin-cli getpeerinfo` in order to get all the connections info (inbound + outbound)

I'm behind a CG-NAT so I thought to use TOR to overcame it but still I have outbound connections but no inbound.

Reindexing my Bitcoin Cash blockchain fails at block 264084

My BUCash was seemingly chugging along fine but for the sake of it I decided to reindex. It seems to have processed all of the block files (with a lot of out-of-order blocks, is that normal?) but now I guess it's trying to validate block 264084 over and over but all my debug is showing me about it something similar to this every time:

The only other similar thing I found was this guy having issues with the exact same block: https://np.reddit.com/BitcoinABC/comments/6omaqm/block_264084_possible_timewarp_problem/
PMing him revealed that he was unable to fix it and simply no longer runs a node.
Can anyone help me out here? Should I just redownload the blockchain?

I joined the full node club as well

Anything else I can do? I run the node all the time except when I sleep, since I turn my computer off when I sleep. I currently have 21 active connections, does adding more connections help? If so, how can I do that?

A tour of the Gridcoin wallet

Hey guys, I thought I would put together an in-depth tour of the Gridcoin wallet software for all of our recent newcomers. Here I'll be outlining all the features and functions the windows GUI wallet has to offer, along with some basic RPC command usage. I'll be using the windows wallet as an example, but both linux and macOS should be rather similar. I'll be including as many pictures as I can as embedded hyperlinks.
Edit: Note that since I originally made this there has been a UI update, so your client will be different colors but all the button locations are in the same place.
This is my first post like this, so please forgive me if this appears a little scatter-brained.
This will not cover the mining setup process for pool or solo miners.
When you launch the wallet software for the first time you should be greeted with this screen.

OVERVIEW TAB

After that prompt, you should be left sitting on the main overview tab with several fields on it.
From top to bottom:

SEND TAB

Now onto the other tabs on the left side. Currently we're on the Overview tab, lets move down to the Send tab. This tab it pretty self-explanatory, you use it if you want to send coins, but I'll go over the fields here:
  • Pay To: Enter a valid gridcoin address to send coins too. Gridcoin addresses always start with an S or and R.
  • Label: Enter a label here and it will put that address in your "address book" under that label for later use. You can leave it blank if you don't want it in your address book.
  • Message: Enter a message here if you want it attached to your transaction.
  • Amount: How many coins you want to send.
  • Add Attachment: Leave this alone, it is broken.
  • Track Coins: This doesn't do anything.

RECEIVE TAB

Now down to the Receive tab. Here you should have a single address listed. If you double click on the label field, you can edit it's label.
  • New: Generate a new address.
If you click on an address, the rest of the options should be clickable.
  • Copy: Copy the selected address to your clipboard.
  • Show QR Code: Show a scan-able QR code for the selected address.
  • Sign Message: Cryptographically sign a message using the selected address.

TRANSACTIONS TAB

The Transactions tab is pretty boring considering we have no transactions yet. But as you can see there are some sorting tools at the top for when you do have transactions listed.

ADDRESS BOOK TAB

The Address Book is where all the addresses you've labeled (that aren't yours) will show up.
  • Verify Message: Verifies a message was signed by the selected address.
The rest of the functions are similar to the functions on the Receive tab.

VOTING TAB

Onto the Voting tab. There wont be any polls because we aren't in sync yet.
  • Reload Polls: Pretty self-explanatory, I've never had to use this.
  • Load History: By default, the wallet will only display active polls. If you want to view past polls you can use this.
  • Create Poll: You can create a network-wide poll. You must have 100,000 coins as a requirement to make a poll. (Creating a poll does not consume the coins)
Here's what the Voting tab will look like once you're in sync

CONTEXT BAR

Now onto the context bar menus on the top.
Under File you have:
  • Backup Wallet/Config: This lets you backup your wallet configuration file just in case.
  • Export: You can export your Transactions tab or Address Book in CSV format.
  • Sign message: Does the same thing as on the Receive tab.
  • Verify message: Does the same thing as on the Address Book tab.
  • Exit: Close the wallet.
Under Settings you have:
  • Encrypt Wallet: Encrypts your wallet with a password. (we'll come back to this)
  • Change Passphrase: Allows you to change your encryption password.
  • Options: Opens the options menu. (We'll come back to this)
Under Community you have:
Under Advanced you have:
  • Advanced Configuration: Opens the Advanced Configuration menu. (Not so advanced if you ask me)
  • Neural Network: Allows you to view solo miners project statistics. It will be largely blank if you're not in sync yet.
  • FAQ: Don't touch this, It is broken.
  • Foundation: Don't touch this, It is broken.
  • Rebuild Block Chain: Starts the client syncing from 0. Don't worry, using this will not make you lose coins.
  • Download Blocks: Downloads the latest official snapshot, can help speed up syncing. The download progress tends to sit at 99.99% for a long time, don't worry, it's working.
Under Help you have:
  • Debug window: Opens the debug window. (We'll come back to this)
  • Diagnostics: Don't touch this, it is broken. This has since been fixed. You can use this to see if there is anything wrong with your setup.
  • About Gridcoin: Opens the About Dialog. This gives you your client version and other information.

OPTIONS

Now back to the options menu under Settings > Options.
Here we have the options menu main tab:
  • Pay transaction fee: The transaction fee that will be automatically paid when you make a transaction.
  • Reserve: You can reserve an amount so that it will always be available for spending.
  • Start Gridcoin on system login: Pretty self-explanatory
  • Detach databases at shutdown: Speeds up shutdown, but causes your blockchain file to no longer be portable.
On the Network tab:
  • Map port using UPnP: Attempts to connect to nodes through UPnP.
  • Connect through SOCKS proxy: Allows you to connect through a proxy.
The window tab is pretty self-explanatory.
The Display tab is also pretty self-explanatory, with the exception of:
  • Display coin control features (experts only!): This allows you to have a great deal of control over the coins in your wallet, check this for now and I'll explain how to use it further down. Don't forget to click "Apply".

ENCRYPTING YOUR WALLET

Now that all of that is out of the way. The first thing you'll want to do is encrypt your wallet. This prevents anybody with access to your computer from sending coins. This is something I would recommend everyone do.
Go to Settings > Encrypt Wallet and create a password. YOU CANNOT RECOVER YOUR COINS IF YOU FORGET YOUR PASSWORD.
Your wallet will close and you will have to start it up again. This time when it opens up, you should have a new button in the bottom left. Now if you want to stake you will have to unlock your wallet. Notice the "For staking only" box that is checked by default. If you want to send a beacon for solo mining or vote, you will need to uncheck this box.

GETTING IN SYNC AND ICONS

Before we continue, Let's wait until we're in sync. Depending on your internet speeds, this could take from several hours to over a day or 2. This can be sped up by using Advanced > Download Blocks, but this can still take several hours.
This is what an in-sync client should look like. Notice the green check to the right of the Receive tab. All of these icons give you information when you hover your mouse over them.
The lock
The arrow tells you if you're staking. If you aren't staking, it will tell you why you're not staking. If you are staking it will give you an estimated staking time. Staking is a very random process and this is only an estimate, not a countdown.
The connection bars tell you how many connections to the network you have.
The check tells you if you're in sync.

WHAT IS STAKING?

Now I've said "stake" about a million times so far and haven't explained it. Gridcoin is a Proof of Stake (PoS) coin.
Unlike bitcoins Proof of Work (PoW), PoS uses little system resources, so you can use those resources for scientific work. PoS works by users "Staking" with their balance. The higher the balance, the higher the chance to create, or "stake" a block. This means you need to have a positive balance in order to stake. Theoretically, you can stake with any amount over 0.0125 coins, but in practice it's recommended to have at least 2000 coins to reliably stake.
Staking is important for solo miners, because they get paid when they stake. Pool miners don't need to stake in order to get paid however. So if you want to solo mine, you'll need to buy some coins from an exchange or start in the pool first and move to solo when you have enough coins.
In addition to Research Rewards for miners, anyone who holds coins (solo miners, pool miners, and investors) gets 1.5% interest annually on top of your coins. So it can be beneficial for pool miners to stake as well.
Here is a snippet of what a research rewards transaction looks like from my personal wallet. I have a label on that address of "Payout address" as you can see here.

UTXOS AND COIN CONTROL

At this point you'll need some coins. You can use one of our faucets like this one or this one to test coin control out.
First let me explain what a UTXO is. UTXO stands for Unspent Transaction Output. Say you have an address with 0 coins in it, and someone sends you 10 coins like I've done here. Those 10 coins are added to that address in the form of a UTXO, so we have an address with one 10 coin UTXO in it.
Now we receive another 5 coins at the same address, like so. Now we have an address with one 10 coin UTXO and one 5 coin UTXO. But how do we view how our addresses are split up into different UTXOs?
Earlier we checked the "Display coin control features" box in Settings > Options > Display. Once that's checked you'll notice there's another section in the Send tab labeled "Coin Control Features". If you click the "Inputs" button, you'll get a new window. And look, there's our 2 UTXOs.
All UTXOs try to stake separately from each other, and remember that the chance a UTXO has to stake is proportional to it's size. So in this situation, my 10 coin UTXO has twice the chance to stake as my 5 coin UTXO. Now wallets, especially ones that make a lot of transactions, can get very fragmented over time. I've fragmented my wallet a little so I can show you what I'm talking about.
How do we clean this up? We can consolidate all this into one UTXO by checking all the boxes on the left and selecting OK.
Now pay attention to the fields on the top:
  • Quantity: The total amount of UTXOs we have selected.
  • Amount: The total amount of coins we have selected.
  • Fee: How much it would cost in fees to send all those UTXOs (more UTXOs = more transaction data = more fees)
  • After Fee: Amount - Fees.
  • Bytes: How large the transaction is in bytes.
  • Priority: How your client would prioritize making a transaction with this specific set of UTXOs selected had you not used coin control.
  • Low Output: If your transaction is less than 0.01 coins (I think).
  • Change: What you will get back in change.
  • custom change address: You can set the address you get your change back at, by default it will generate a new address.
So let's fill out our transaction so we end up with 1 UTXO at the end.
In "Pay To:" Just put any address in your wallet, and for the amount put what it has listed in the "After Fee" Field. Just like this.
Notice how we get no change back.
Now click "Send", we'll be prompted to enter our passphrase and we're asked if we want to pay the fee, go ahead and click "Yes".
Now if we go back to the Overview tab we get this funky icon. If you hover your mouse over it, it says "Payment to yourself", and the -0.0002 GRC is the network transaction fee.
(Ignore the first one, that was me fragmenting my wallet)
Now if we look at the Coin Control menu, we can see that we've slimmed our wallet down from 7 UTXOs to 1.
Now why would you want to use coin control?
2 Situations:
  1. UTXOs less than 0.0125 coins cannot stake. So you can combine a lot of tiny, useless UTXOs into 1 bigger one that can stake.
  2. After a UTXO stakes, it cannot stake for another 16 hours. So if you have 1 large UTXO that is big enough to stake more than once every 16 hours, you can split it into smaller UTXOs which can allow you to stake slightly more often.
  3. By default, the wallet will always generate a new address for change, which can make your wallet get very messy if you're sending lots of transactions. Keep in mind that more UTXOs = larger transactions = more fees.
Sidenote - When you stake, you will earn all research rewards owed reguardless of which UTXO staked. However, you'll earn the 1.5% interest for that UTXO. Not your whole wallet.

FORKING

A fork is when the network splits into multiple chains, with part of the network on each chain. A fork can happen when 2 blocks are staked by different clients at the same time or very close to the same time, or when your client rejects a block that should have been accepted due to a bug in the code or through some other unique circumstance.
How do I know if I'm on a fork?
Generally you can spot a fork by looking at the difficulty on your Overview tab. With current network conditions, if your difficulty is below 0.1, then you're probably on a fork.
You can confirm this by comparing your blockhash with someone elses, like a block explorer.
Go to [Help > Debug Window > Console]. This is the RPC console, we can use to do a lot of things. You can type help to get a list of commands, and you can type help [command you need help with] (without the brackets) to get information on a command. We'll be using the getblockhash [block number] command.
Type getblockhash [block number] in the console, but replace [block number] with the number listed next to the "Blocks:" field on the Overview tab.
This will spit out a crazy string of characters, this is the "blockhash" of that block.
Now head over to your favorite block explorer, I'll be using gridcoinstats. Find the block that you have the hash for, use the search bar or just find it in the list of blocks.
Now compare your hash with the one gridcoinstats gives you. Does it match?
If it matches, then you're probably good to go. If it matches but you still think you're on a fork, then you can try other block explorers, such as gridcoin.network or neuralminer.io.
If it doesn't match, then you need to try to get off that fork.
How do I get off a fork?
  1. Just wait for an hour or two. 95% of the time your client is able to recover itself from a fork given a little time.
  2. Restart the client, wait a few minutes to see if it fixes itself. If it doesn't restart again and wait. Repeat about 4 or 5 times.
  3. Find where the fork started. Using the getblockhash command, go back some blocks and compare hashes with that on a block explorer so you can narrow down what the last block you and the block explorer had in common. Then use reorganize [the last block hash you had in common]. Note that reorganize takes a blockhash, not a block number.
  4. Use Advanced > Download Blocks.
  5. If none of this works, you can take a look at social media (reddit/steemit) and see what other people are saying.

CONFIGURATION FILE

Your configuration file depends on your operation system:
  • On Windows: %appdata%\GridcoinResearch\
  • On Linux: ~/.GridcoinResearch/
  • On MacOS: /Users/USERNAME/Library/Application/Support/GridcoinResearch/
And it should look like this.
If you open up your gridcoinresearch.conf, you'll see the default one it generated. Note that if you entered your email earlier, the first line will have your email on it instead of "investor". If you decided you want to solo mine but didn't enter your email when you first started the wallet, go ahead and put your email on the first line in place of "investor". If you're a pool miner, just leave it as "investor".
Next, it's recommended that you use the addnodes on the gridcoin wiki. So our gridcoinresearch.conf will look like this.
A useful line for solo miners is PrimaryCPID=[YOUR CPID]. Sometimes your wallet can pick up on the wrong CPID so it's good to have that in there if you're solo mining.

RUNNING A LISTENING NODE

A listening node is a node that listens for blocks and transactions broadcasted from nodes and forwards them on to other nodes. For example, during the syncing process when you're getting your node running for the first time, you're downloading all the blocks from listening nodes. So running a listening node helps support the network.
Running a gridcoin listening node is simple. All you need to do is add listen=1 to your gridcoinresearch.conf and you need to forward port 32749 on your router.
If you don't know how to port forward, I'd suggest googling "How to port forward [your router manufacturer]".

PIVX Core Wallet 3.0.5 final release (November 13th, 2017) - Mandatory Upgrade

Github release link
Forum Post

Important Notes

Upgrade instructions

1- Download the appropriate release for your platform from the Github release link. For command line installs/updates this link may help.
2- Start up your client and see if you are on the wrong chain by using this link (Am I forked?) or manually comparing your latest block hash against the [block explorer](www.presstab.pw/phpexplorePIVX/index.php#)
3- If you are on the correct chain, let it fully sync (or as far as it will go) and then repeat step 2. If you are still on the right chain move on to step 4. If you're on the wrong chain, download the chainstate from this link (mirror) and follow the instructions to install it. Do NOT delete wallet.dat or your backups folder. Once this is done, restart your client and let it finish syncing
  1. stop your wallet and/or daemon
  2. locate the folder with the blockchain folders (usually ~/.pivx/)
  3. do a complete(!) backup of this folder in case something goes wrong
  4. completely remove the folders "blocks", "chainstate", "sporks" and "zerocoin"
  5. download one of the snapshot-files (preferably the newest one) above into this folder
  6. unpack the snapshot file: 'unzip '
  7. the folders deleted above are now replaced by the ones from the snapshot
  8. restart your wallet and/or daemon
4- On this step you should be fully synced and on the right chain. Using the debug screen or pivx-cli, use the command
spork show 
to output your spork status. Have a look at spork 16 and make sure the value is 1510179528 (now 1609459199). If it is, go ahead and start staking.
If you are having trouble getting the correct value for spork 16, try adding nodes to your pivx.conf file that are protocol 70912. A list of 70912 nodes can be found at http://www.presstab.pw/phpexplorePIVX/nodes.php . This can be done from the debug menu or with pivx-cli by saying
addnode 123.45.67.89 add 

Notable Changes

libzerocoin Exploit Fix

zPIV relies on a 3rd party library called libzerocoin. All currencies that utilize the zerocoin protocol use libzerocoin, and many of those currencies have been exposed to an exploit which allowed for the creation of multiple zero-knowledge spending proofs for one single zerocoin mint. The PIVX developers were able properly identify the exploit, track down any fraudulent spending proofs, link the fraudulent spending proofs with their one valid proof that they were mutated from, and remove any mints from the accumulators that were derived from the invalid spends.

zPIV Maintenance Mode Spork

Handling the above noted libzerocoin exploit required the PIVX team to immediately release a patched wallet to as many users as possible which rejected bad spends and also disabled all zPIV transactions in general. The process of releasing a patched wallet in such a small time frame is frustrating and difficult for all members of the PIVX team and especially users of PIVX. The PIVX developers have added a new spork which allows for zPIV transacting to be turned on/off without having to release a patched wallet. This will allow much smoother operation if any problems occur in the future, and should also allow exchanges and 3rd party services to continue to operate even if zPIV is in maintenance mode.

Accumulator Code Refactor

The zPIV accumulator code has undergone a major refactor. Accumulators are one of the most essential components of the zerocoin protocol, and also one of the most computationally expensive parts of the protocol. This refactoring speeds up syncing and spending of zPIV by over 5x. The new code also allows for spending of zPIV with only 2 required mints occurring on the network after your mint has been added, whereas before 3 were required. This refactor allows for lighter resource load and a smoother user experience.

Money Supply Indexing

The exploit in libzerocoin threw off some of the wallet's internal money supply calculations for both the zPIV supply and the PIV supply. User's wallet's will automatically recalculate the supply on block 908001. User's also have the ability to recalculate supply using the startup flag reindexmoneysupply.

More Extensive Tracking of zPIV Supply Through RPC

More information has been added to the getinfo and getblock RPC calls, which now display the total zPIV supply as well as the balance for each zPIV accumulator.

Multisig GUI

Provides functionality which is currently only available through raw transactions. Multisignature addresses require signatures from multiple parties before coins belonging to the address are spent. Accessed through the File dropdown menu.

FAQ

  • Will I lose piv or zpiv?
    • No. Backup your wallet.dat again for good measure and never delete a wallet.dat file.
  • My wallet is stuck on block ?
    • Check if you're forked (Am I forked?) and then check if you're really on v3.0.5. If you're on the right version and chain, just hang tight and your wallet will find a good node to sync with eventually. Contact support if it's more than a few hours and the problem persists
  • My zPIV balance is incorrect
    • Contact support in discord or via the Support Portal. Please note that during the upgrade period and zerocoin maintenance mode there may be delays.

Need help trying to figure out why block contains few transactions

I'm trying to troubleshoot bitcoin block 0000000000000000001aaef7bdca12abf93c862b5df4db96ca6130b6445655c1. The Prohashing pool found this block this morning, but it only has 9 transactions. The blocks around it appear to have many more transactions than this one does, some as many as 1300. Yet, getblocktemplate returned just a few transactions. This is the third block where there were about the same number of transactions.
Since all the other coins mined by the pool contain a lot of transactions, it's unlikely that this problem is a bug in the mining server that limits blocks to 9 transactions. For example, litecoin block 9d24ac1c74689309c08f4d2bd4eb47210c8f44f4c788472fd003bf7d8d4ad562 contains 19 transactions. Bitcoin Cash block 000000000000000000c966e7c0f566df540efc2b30604188a7cf511cb8e41730 also contains more than 9 transactions. That's why I think the problem is a configuration error.
Here's the bitcoin.conf file, in case that helps.
server=1 daemon=1 port=4516 rpcuser=daemon rpcpassword=[censored] rpcport=3210 rpctimeout=30 blocknotify=/usshare/blocknotify_new.sh --user=daemon --pass=[censored] #maxconnections=8 txconfirmtarget=6 minrelaytxfee=0.00005 addnode=v4.us-east.fibre.bitcoinrelaynetwork.org 
and here's what getinfo() returns:
{ "version": 1000300, "protocolversion": 80002, "walletversion": 60000, "balance": 15.98119571, "blocks": 534848, "timeoffset": 0, "connections": 27, "proxy": "", "difficulty": 5949437371609.53, "testnet": false, "keypoololdest": 1529134290, "keypoolsize": 100, "unlocked_until": 0, "paytxfee": 0.00000000, "relayfee": 0.00002423, "errors": "Warning: unknown new rules activated (versionbit 1)" } 
While a lot of discussion here is about BCH, all of our employees are banned from all of the Core's discussion forums, so this is the only place we can go. Any help someone can provide would be appreciated, as including more transactions in blocks would also allow the networks to function better for everyone.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

Two devices, sub devise cannot connect to main device.

Hello experts,
I have two computers running bitcoind, and I'm having trouble with downloading blocks to my sub node from my main node. IP address of main node: 192.168.1.31 IP address of sub node: 192.168.1.32
On my second node I have added addnode=192.168.1.31 to bitcoin.conf file.
In the debug.log file of sub node I have error message:
connect() to 192.168.1.31:8333 failed after select(): Connection refused (111) 
Both nodes running over Tor. UFW settings for main:
192.168.1.31:~ # ufw status Status: active To Action From -- ------ ---- 22 ALLOW 192.168.1.0/24 8333 ALLOW Anywhere # Bitcoin mainnet 9051 ALLOW Anywhere # tor 50002 ALLOW Anywhere # eps 8333 (v6) ALLOW Anywhere (v6) # Bitcoin mainnet 9051 (v6) ALLOW Anywhere (v6) # tor 50002 (v6) ALLOW Anywhere (v6) # eps 
Firewall settings sub node:
192.168.1.32:~ # firewall-cmd --list-all public target: default icmp-block-inversion: no interfaces: sources: services: ssh dhcpv6-client ports: 8333/tcp 9050/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules: 
Any help would be greatly appreciated.

Bitcoin ABC 0.18.8 released!

Bitcoin ABC version 0.18.8 is now available from:
https://download.bitcoinabc.org/0.18.8/
This release includes the following features and fixes: - dumpwallet now includes hex-encoded scripts from the wallet in the dumpfile - importwallet now imports these scripts, but corresponding addresses may not be added correctly or a manual rescan may be required to find relevant· transactions - getblock 2 (verbosity = 2) now returns hex values in transaction JSON blobs - Remove miner policy estimator in favor of minimum fees, also remove fee_estimates.dat. Old copies will be left in place. - The log timestamp format is now ISO 8601 (e.g. "2019-01-28T15:41:17Z") - Behavior change: in case of multiple values for an argument, the following rules apply: - From the command line, the last value takes precedence - From the config file, the first value takes precedence - From the config file, if an argument is negated it takes precedent over all the previous occurences of this argument (e.g. "foo=2 \n nofoo=1" will set foo=0) - The configuration files now support assigning options to a specific network. To do so, sections or prefix can be used: main.uacomment=bch-mainnet test.uacomment=bch-testnet regtest.uacomment=bch-regtest [main] mempoolsize=300 [test] mempoolsize=200 [regtest] mempoolsize=50 The addnode=, connect=, port=, bind=, rpcport=, rpcbind= and wallet= options will only apply to mainnet when specified in the configuration file, unless a network is specified.

MNO is a masternode coin monitoring and stats service. MNO does not research or recommend any coin. Finding difficulty in syncing your wallet or connecting it to the network. You can easily resolve this by adding nodes to your wallet. Here is a quick guide on Bitcoin wallet nodes. Bitcoind – a daemon program that implements the Bitcoin protocol, is controlled through the command line. It is one of the main components of the Bitcoin network node software. Bitcoin software exists in two forms: a GUI application and a background application (daemon on Unix, service on Windows). Bitcoin.org used to provide this bootstrap file to accelerate the synchronization process. But that file is not available and they no longer maintain it. Because syncing wallets using bootstrap.dat method is no longer advantageous and is not necessary anymore.
