ArcBlock offers OCAP Libraries, a comprehensive suite of JavaScript packages for building decentralized identity applications. The platform includes three main components: @arcblock/did for creating and validating Decentralized Identities compliant with the ArcBlock DID specification, @ocap/wallet for creating and managing DID-compatible cryptographic wallets with signing and verification capabilities, and @ocap/util as a foundational toolkit providing utility functions for data conversion and encoding.
These libraries are designed to work seamlessly together, with the typical workflow involving wallet key management and DID generation. The wallet secures cryptographic keys while the DID library creates the public identifier. The platform enables developers to build applications with self-sovereign identity features in a decentralized environment.

Measured after ArcBlock went live on Zivaro Launch on 4 November 2026.
Day 3 since launch. Next receipt: day 30, 4 Dec 2026. These are measurements, not proof of cause: many things move these numbers. Figures we have not measured are left out.

The three main packages are @arcblock/did for working with ArcBlock DIDs, @ocap/wallet for creating and managing DID-compatible cryptographic wallets, and @ocap/util as a foundational toolkit for utility functions.
While these libraries can be used independently, they are designed to work seamlessly together. The typical workflow involves using @ocap/wallet to manage the cryptographic keys and then passing those keys to @arcblock/did to generate the corresponding DID address. The wallet secures the keys while the DID library creates the public identifier.
The @ocap/util library serves as a foundational toolkit providing shared utility functions used across multiple OCAP libraries, including essential helpers for data type conversion, encoding like Base58 and Hex, and other low-level operations.
