B137 Protocol

A Composable DID Protocol for the Bitcoin Network

B137 is a significant public good that revolutionizes social relationships within the Bitcoin ecosystem and represents a groundbreaking experiment. The content of this whitepaper does not constitute financial advice.

The B137 protocol is proposed based on the Ordinals protocol, allowing anyone to create composable DIDs on the Bitcoin blockchain in a fully permissionless and decentralized manner. B137 grants users the ability to monetize their digital identities and facilitating on-chain value exchanges and social ecosystems.

DIDs adhered to B137 protocol are distinct from existing DIDs such as Ethereum Name Services (ENS). The names resolved by B137 are determined by two types of assets: B137-DID and B137-TLD. B137-DID is a fungible token based on BRC20, while B137-TLD is a non-fungible token asset.

Users can inscribe a string as a username on B137-DID. This username can be resolved independently, like alice. Alternatively, it can be bound to a B137-TLD to represent an affiliation, enabling the conventional second-level domain resolution in the form of username.TLD, like alice.b137.

B137-TLD can be used as a top-level domain by inscribing a string, initiating a DID system based on the Bitcoin network. It also allows for the setting of Royalties based on demand.
