1.3.1.20 - Fast sync update

This update fixes the underlying sync issues from previous builds (protocol message size cap) and adds a few new features to the core codebase.

BugFixes:

• Upgrade the protocol message size (buffer) from 2MB to 4MB to be sure the header downloads syncing the chain does not bork your database, stopping the blockchain sync process.

New Features:

Fast sync

If you run the wallet or daemon from the command line with the -fastsync argument, it will allow the wallet to sync the entire chain exponentially faster. In our recent tests the sync would take anywhere from 2 -10 hours depending on hardware and settings. It achieves this by minimizing the number of verification checks on individual blocks from the pre-fork height as well as allowing an increased number of blocks to be accepted from peers at any given time. Keep in mind that this puts more of a burden on your computers resources so use at your own risk. Command line will look like this newyorkcoin-qt.exe -fastsync

disconnectnode rpc function:

From within the QT wallets console or from the cli you can now disconnect from nodes that you are connected to at will. This function was useful in diagnosing sync and connection issues and we thought everyone should know about it's existence.

This release also replaces the previous version for those that have issues syncing. Just download and run this build, there should be no need for deleting files or reloading the chain from the bootstrap.

Sync from bootstrap (not using -fastsync)

If you would rather sync via the bootstrap, you can download the bootstrap from the following link:
https://www.dropbox.com/s/sili4imk39fn5mn/bootstrap.zip?dl=0

• Stop your QT wallet of daemon
• Download: Bootstrap November 4th 2018 (Up to Block 4817000) and unzip the file in the QT DataDir
• Backup Wallet.dat from your datadir. Copy it to a safe location.
  • For Windows, that would be “C:\Users[USERNAME]\AppData\Roaming\newyorkcoin”.
  • For Mac, that is: “~/Library/Application Support/newyorkcoin”
• Delete all files from your datadir (see above) EXCEPT WALLET.DAT and newyorkcoin.conf
• Start the QT wallet and the bootstrap should start ‘importing blocks from disk’. This import will take a while (few hours). After the import is complete, the sync should be close to 100%.

v1.3.1.18 - Minor Update: Blockchain Sync

This update should fix some issues people are having with syncing the blockchain on their devices.
The issue that is being addressed in this release makes sure the new QT wallet does not try to sync from older pre-fork nodes (v1.2.0.8 and below)

People that have sync issues can and should resync the entire blockchain on their PC. To do so, take the following actions

• Stop the running QT Wallet
• Install the new version downloaded here, but DO NOT start it yet.
• Browse via Explorer to your NewYorkCoin datadir:

For Windows, that would be “C:\Users[USERNAME]\AppData\Roaming\NewYorkCoin”.
or you own defined datadir used in the Batch startup script you created

• Delete all files in that folder, except for newyorkcoin.conf and wallet.dat
• Modify newyorkcoin.conf and remove all the addnode occurences (The NYCoin QT search via a DNSSeeder for good known nodes)
• Download: Bootstrap November 4th 2018 (Up to Block 4817000) and unzip the file in the QT DataDir
• Start the QT wallet and the bootstrap should start ‘importing blocks from disk’. This import will take a while (few hours). After the import is complete, the sync should be close to 100%.

1.3.1.17 Beta build - Mandatory update for v1.3 wallets

Latest Windows and OSX builds for wallet 1.3 are out. If you have a currently running 1.3 node of any version you should update to this (1.3.1.17) release asap. There are still some minor fixes to be made to this version of the wallet but this release will get faulty (1.3.0.0-1.3.1.16) wallets out of circulation.

Before starting the new version of the wallet, make sure to delete peers.dat from the data folder.
Default locations of the data folder:
On windows: %appdata%\newyorkc\peers.dat
On MacOS: ~/Library/Application\ Support/newyorkc/peers.dat
On Linux: ~/.newyorkc/peers.dat

Until more testing is done, please do not mine with this codebase, this is for use as a node and wallet only.

Always scan before downloading using https://www.virustotal.com/#/home/upload

Minor Update to 1.2.0.8

Minor build update to re-add rpc mining functionality. This was thought to have flagged AV software but it turns out not to have been the case and the functions that were removed are necessary for pool operators and testnet operations. If you are operating a pool or a dedicated node, please update as soon as you can.

Also, same precautions should be taken. Make backups before you switch over!

NYCoin QT Wallet v1.2.0.7_beta

New Features:

• conf file is now auto-generated
• Added coin-control (see http://cryptomining-blog.com/tag/what-is-coin-control/ for more info)
• replace BerkelyDB with LevelDB

Updates and Bug Fixes:

• Fixed qr code generator
• built with openssl 1.0.2o
• pools will now accept lower fee blocks (with the new daemon)
• Connections from Rabbitcoin clients (or others) will now be dropped.
• Dust soft limit reduced to 0.001 nyc
• Min tx fee reduced to 0.01

Important Notes:

• When upgrading from the previous version, be sure to backup your old wallet through the QT application menu, or copy the wallet.dat to a safe location.
• You can keep your block data files right where they are, the wallet will automatically locate and begin re-indexing. Re-indexing takes quite a bit of time due to the conversion from BerkelyDB to LevelDB, expect about 12 hours. We will be posting a bootstrap file with instructions when it becomes available.
• For the Windows Release: also included in the zip file a build of the headless daemon. You can run it from the command line and it will act as a node on the NYC network much the same as your wallet does while it is running. The big difference is that there is no GUI and it is a bit more cumbersome to interact with. However, if you have a static IP and want to run a dedicated node, it is there to do just that. If you do happen to want to spin up a dedicated node, please let a member of the dev team know so that we can add your IP to the list of dedicated nodes in the wallet config files.

However, if you have a static IP and want to run a dedicated node, it is there to do just that. fF you do happen to want to spin up a dedicated node, please let a member of the dev team know so that we can add your IP to the list of dedicated nodes in the wallet config files.
