Bitcoin Optech Newsletter

  • 01:22:22 240
    • Notable code and documentation change: Bitcoin Core #25943 adds a parameter to the sendrawtransaction RPC to limit the amount of funds burned per output. If the transaction contains an output whose script is heuristically deemed to be unspendable (one with an OP_RETURN, an invalid opcode, or exceeding the maximum script size) and whose value is greater than maxburnamount, it will not be submitted to the mempool. By default, the amount is set to zero, protecting users from unintentionally burning funds.

    • News: Alternative design for OP_VAULT: Greg Sanders posted to the Bitcoin-Dev mailing list an alternative design for providing the features of the OP_VAULT/OP_UNVAULT proposal (see Newsletter #234). His alternative would add three opcodes instead of two.
