Since mainnet launch, we have been working tirelessly on updating our ARK core, fixing wallet bugs, improving the wallet UI, and updating ARKcommander to make installation and updates as simple as possible (which now supports rebuilding from fresh snapshots that are created every 15 minutes). So here is a quick recap on what the ARK Crew has achieved during this short time. A special thank you to all our contributors and community who consistently stick together, help each other out, and discover bugs — without you we wouldn’t be here at all!

Note: all running delegates (active and relay) scroll down to section of ARKcommander.sh update and update your ARK-node core!

#Bug Fixes

Yesterday (March 30th) a new core update was pushed after 2 issues were discovered and fixed:

Since ARK uses BIP32 and HD addressing (like Bitcoin) you could send your ARK to a Bitcoin addresses (it wasn’t actually sent to Bitcoin, but you could send it to a wallet that “can’t exist” on the ARK network). This has been fixed, and in addition you can no longer send to an address that cannot be generated within the ARK network (note that all ARK addresses on mainnet start with capital letter ‘A’). Yesterday a bug was discovered by our community that occurred twice on the blockchain in 2 blocks:

- block 3873 was forged over a block time (too late)

- block 84675 was forged over a block time (too late)

The first bug, at block 3873, was a corner case and was harmless because block rewards had not been activated yet. The second was rewarded at block 84675, and assigned 2 ARK to delegate bikerleszno. This should not have occurred as it was forged over a blocktime. As a consequence if a node tried to rebuild from block zero it resulted in being stuck at block 93477 (at that block bikerleszno emptied his account causing this problem).

A fix and update to the ARK core to prevent forging over a blocktime was completed in less than 2 hours (by our main developer ‘fixcrypt’) after being noticed by our great community on Slack yesterday (thank you all who noticed this while rebuilding and brought it to our attention!).

Don’t forget we are running yearly 200,000 ARK Github Bounty for all developers / coders / hackers / hobbyists , … to take part : CLICK

# Updating ARKcommander and Updating ARK Core

All active and relay nodes should follow this quick guide to update your ARKcommander script and update ARK core.

Login to your server Input these commands:

cd ~/

rm ARKcommander.sh

rm -rf snapshots

wget https://ark.io/ARKcommander.sh

bash ARKcommander.sh Once in ARKcommander choose option ‘3’ and press [ENTER] — your node will update and restart automatically. If by any chance the config file from the update gets overwritten(when you start you’ll see a message there is no delegates in config file means your config file with passphrase was rewritten with default config file), go back into ARKcommander and choose ‘5’ and press [ENTER] — you will be asked to provide your forging passphrase — paste it and press [ENTER] and node will restart.

How to rebuild from a snapshot if your node gets stuck?

cd ~/

bash ARKcommander.sh

In ARKcommander choose option ‘4’ and press [ENTER]. You will be asked if you want to download a fresh snapshot — choose ‘Y’ and press [ENTER]. You will then be asked if you want to restore from a snapshot — again choose ‘Y’ and [ENTER].

When you start it next time you will also be presented with a list of snapshots. The most current snapshot is listed under number 1. Choose ‘1’ and [ENTER] and you are done!

Your blockchain will now sync from a block that is less than 20 minutes old and syncing will only take a few seconds (as opposed to rebuilding from zero which can take 30 minutes).
