BRC-137 is a protocol designed to leverage Bitcoin's blockchain for decentralized identity (DID) applications. It introduces an ecosystem where users can manage digital identities, earn royalties and gain liquidity. The protocol includes BRC137-DELEGATOR assets, limited to 21 Genesis Rocks, allowing holders to become Delegators in the BRC137 ecosystem. These Delegators play a crucial role in batching user operations on the Bitcoin blockchain, thereby reducing costs. The platform also offers BRC137-TLD assets, vital for establishing digital identities and brand recognition within the community.
