This updates the assumed valid block for the main and test networks as follows:

mainnet: 458d6a8e11c916d4149ca8bc5c7aaaaf16cc61971b0c20764c07edf85df44eb6
testnet: e5d29f04aa33d19dfe4935ca2e70d8f640a7263b653f57ce600b6829d6f2cf48

Reviewers should verify that:

  • The mainnet block is at least 4032 blocks behind the current tip
  • The testnet block is at least 10080 blocks behind the current tip
  • The block hashes and heights match their local instances

The following commands may be used to verify the hashes:

$ dcrctl getblockhash 1026597
458d6a8e11c916d4149ca8bc5c7aaaaf16cc61971b0c20764c07edf85df44eb6
$ dcrctl --testnet getblockhash 1780540
