v3.1.0

fxCore V3.1.0

This is the final release for the fxv3 upgrade which is proposed to take place at height 8,756,000 which should occur approximately at Feb 09th, 2023 at 02:00:00 UTC.

It contains the following changes:

• Support Avalanche C-chain cross-chain
• Support cross-chain tokens: AVAX, SAVAX, QI, BAVA and WBTC (erc20)
• Support IBC standard transfer transaction
• See CHANGELOG.md for details.

On-Chain Upgrade Process

When the network reaches the halt height, the state machine program of the fxCore will be halted. The classic method for upgrading requires all validators and node operators to manually substitute the existing state machine binary with the new binary.Because it is an onchain upgrade process, the blockchain will be continued with all the accumulated history with continuous block height.

Potential Risk Factors

Although very extensive testing and simulation has taken place there always still exists a risk that the fxCore might experience problems due to potential bugs or errors from the new features. If the chain is experiencing app hash mismatches or serious problems, validators should stop operating the network immediately. fxCore Contributors will coordinate with validators in the #validators-verified channel to create and execute a contingency plan. Likely this will be an emergency release with fixes or the recommendation to consider the upgrade aborted and revert back to the previous release of fxCore (v2.4.x).
