.bit, a decentralized identity protocol under d.id, announced that it will soon undergo a major technical upgrade to be compatible with the RGB++ protocol, making .bit an asset running on the Bitcoin layer. Currently, .bit already supports the parsing and binding of Bitcoin addresses, enabling the transfer of Bitcoin and RGB++ assets. RGB++ is an extension protocol based on RGB, which maps Bitcoin UTXO to the Cell of Nervos CKB through isomorphic binding, bringing Turing-complete contract extensions and performance extensions to Bitcoin without cross-chain and without loss of security. The .bit team has previously completed a $13 million Series A financing.
