XinFin Delegated Proof of Stake (XDPoS): Major Upgrades at Block number 38383838.

XinFin’s XDC Network update named “Andromeda” on its XDPoS consensus protocol going live at block number 38383838, estimated on 1 December 2021.

What innovative features will the Andromeda upgrade activate?

  • Solidity Upgrade to v0.8.x: XinFin’s XDPoS is upgrading its EVM (Ethereum Virtual Machine) to support the latest version of solidity. Upon upgrade, XinFin’s developers will bypass extensive customization when deploying code from different EVM chains.
    This feature will support XinFin’s ecosystem partners and enhance internal product development.
  • Transaction Fee Address: Going forward, transaction fees will transfer to the owner’s address instead of the coinbase/ miner’s address.
  • Fixed and Added Eth_chainId: With the Eth_chainId, the system will be more secure. That’s due to improvements in the replaying of protection transactions. This will provide military-grade security, supported by forensic monitoring to identify misbehaving nodes.
  • Reward halving issue: The upgrade fixes the issue of fewer rewards to master node owners. With the improved rewards, nodes will be incentivized to join and maintain the XDC Network.
  • Multiple Miner address Fixed: The upgrade handles issues relating to multiple miner addresses that could cause a block creation delay on the Mainnet.
