ChainCatcher news, the decentralized identity protocol .bit under d.id announced the completion of the RGB++ upgrade. Leveraging the isomorphic binding feature of CKB, it has become a Bitcoin layer DID asset to serve the user identity needs of the Bitcoin ecosystem. This upgrade makes .bit compatible with CKB's Spore digital object protocol at the asset level, enhancing compatibility and transaction liquidity with CKB ecosystem Dapps. The DOB asset trading market Omiga will become one of the first layer two network platforms to support .bit trading, and in the future, it will also be listed on major RGB++ trading markets.d.id completed a $13 million Series A financing in 2022, and its DID protocol .bit has nearly 100,000 registered users. In addition, d.id recently launched a new narrative direction called "Humanity Matters," helping users express their unique identity value through .bit and the achievement protocol Padge.

ChainCatcher news, the decentralized identity protocol .bit under d.id is preparing for 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 resolution and binding of Bitcoin addresses, enabling the transfer of Bitcoin and RGB++ assets.RGB++ is an extension protocol based on RGB, which maps Bitcoin UTXOs to Cells on Nervos CKB through isomorphic binding, bringing Turing-complete contract extensions and performance enhancements to Bitcoin without cross-chain requirements and without compromising security.The .bit team has previously completed a $13 million Series A financing.

ChainCatcher news, according to official news from Galxe, Galxe has launched the Galxe Protocol, a decentralized identity protocol based on zero-knowledge proofs, allowing users to have complete control over their private data and identity.The Galxe Protocol is a permissionless self-sovereign identity infrastructure that enables builders to create algorithms to prevent counterfeiting, reputation systems, credit systems, personal data markets, decentralized review systems, and more. The core of the Galxe Protocol includes a series of smart contracts deployed on-chain and SDK tools that allow developers to build and use these contracts to issue or verify off-chain credentials.The Galxe Protocol has four main roles: credential holders, issuers, verifiers, and credential type designers. In the current Galxe platform, Galxe designs and provides various types of credentials for projects to use. Project owners verify and issue credentials to eligible participants, who then become credential holders.

ChainCatcher message, the identity-centric crypto project Worldcoin co-founded by OpenAI CEO Sam Altman, has launched the decentralized identity protocol "World ID." Through PoP credentials, the World ID protocol enables everyone to prove their humanity online without the need for a third party. The protocol utilizes zero-knowledge proofs to maximize privacy, ultimately being managed by individuals through World ID itself.Currently, the initial versions of hardware devices, mobile clients, and deployment mechanisms have been implemented, all of which will gradually become decentralized. Applications can interact with this proof on the protocol through the recently launched SDK. The protocol itself is permissionless and is designed to ultimately support a variety of credentials that anyone can prove.World ID will be compatible with verified credential standards, allowing for the representation of the diversity of personal social interactions (soulbound tokens, cross-social data, etc.). As of now, over 1.4 million people have participated. (source link)
