301 - Blind Merged Mining (Consensus layer)
BIP: 301 source Layer: Consensus (soft fork) Title: Blind Merged Mining (Consensus layer) Authors: Paul Sztorc CryptAxe Status: Draft Type: Specification Assigned: 2019-07-23 License: BSD-2-Clause Table of ContentsAbstractMotivationNotation and ExampleSpecificationBMM AcceptBMM RequestBackward compatibilityDeploymentReference ImplementationCopyright Abstract Blind Merged Mining (BMM) allows SHA-256d miners to collect transaction fee revenue from other blockchains, without running any new software (i.e., without "looking" at those alt-chains, hence "blind"). Instead, this block-assembly work is done by alt-chain users. They choose the alt-chain block, and what txns go in it, the fees etc. Simultaneously, these users "bid" on L1 to win the right to be the sole creator of the alt-chain block. BIP-301 ensures that L1 miners only accept one bid (per 10 minutes, per L2 category), instead of taking all of them (which is what they would ordinarily do). Motivation ...

BIP-300 emphasizes slow, transparent, and auditable withdrawals that are easy for honest users to get right and hard for dishonest miners to a...
