aionnetwork / aion

This release is a mandatory update.

This kernel v1.6.1 release includes the consensus protocol upgrade. This consensus protocol upgrading changed the staker's signature scheme, changed the mining block rewards adjustment, ad rollback the transactions have been sent to the invalid destination (Not an Aion addresses). The upgrade will be implemented on mainnet at block number 7441441 and amity at block number 3658559

The Java kernel 1.6 (rev 0a5929a) migration guide

If your kernel already upgraded to v1.6 (rev 0a5929a), you can upgrade the node again or do manually configuration update. The codebase is the same as the v1.6.1 except the protocol upgrade settings.

If you run v1.6 kernel on the mainnet network, please edit the fork.properties file in the folder networks/mainnet, and update the number '7441440' under the tag 'v1.6' to '7441441'
If you run v1.6 kernel on the amity network, please edit the fork.properties file in the folder networks/amity, and update the number '3658558' under the tag 'v1.6' to '3658559'

If you are a staking pool operator or a solo staker, this release will requires the block signer v1.2 and not compatible with v1.1, you can download it from the release page of the block signer repo or you can find it in the tooling folder inside the release package.

• Please backup the config file of the block signer before you update the block signer. You might need to update the coinbase address if the config file has been overwritten.
