Mandatory Update

What’s Changed

This is a mandatory update for the upcoming Eunos Paya chain upgrade. It contains key features and fixes.
Eunos Paya upgrade is set for block 1072000 (approx. ETA Thursday, 05 Aug 2021) on mainnet.

Update of mainnet node before the chain upgrade block is REQUIRED.

Key changes

• Added: Masternodes now optionally support 5 year and 10 year timelocks for increased staking power of 1.5x or 2x respectively.

  • This can be used after Eunos Paya upgrade with an additional parameter to createmasternode RPC that takes in FIVEYEARTIMELOCK or TENYEARTIMELOCK argument. Please note that this means the masternode once created cannot be resigned for the given period, and the collateral is locked.
  • Use defi-cli help createmasternode for more info.

• Changed: Improved InterChain Exchange (atomic swap) consistency. Atomic swap users should find swaps are smoother and successful after Eunos Paya upgrade than before.

• Changed: RPC getmintinginfo is now deprecated. Please switch to getmininginfo instead.
