BAP、BitcoinSchema、1sat ordinals、sigma protocol support for java

Requirement

java>=11 maven>=3.6

Introduction

1.Integrate BAP with bitcoinschema、1sat ordinals 、sigma protocol to enable user transactions and identity association. Ensure compatibility with the following protocols to achieve interoperability: https://github.com/icellan/bap https://github.com/icellan/bsocial https://github.com/unwriter/b https://github.com/rohenaz/map https://github.com/attilaaf/AUTHOR_IDENTITY_PROTOCOL https://github.com/bitcoinschema/js-1sat-ord https://github.com/BitcoinSchema/sigma

2.Hiding the complexity of front-end development

You can achieve API services using the metanet4j-sdk. API callers only need to understand the API documentation, just like regular application development. They don't need to be concerned with the specific implementation of the underlying protocol. This is very helpful in simplifying development.

3.Remote signing for enhanced security with unmanaged keys

• Pending implementation of remote signing interface. Separating transaction construction from signing allows clients to perform the signing process, eliminating the need for service providers to manage user private keys. With remote signing, user private keys do not need to be transmitted over the network and remain securely stored locally. This provides convenience for applications that require higher security.

4.Server-side support for asynchronous tasks

By assembling transactions on the server-side, it becomes convenient to execute transactions asynchronously for tasks such as uploading large files to the blockchain.

Features

1. Support for ECIES shared key encryption and decryption. test case see: com.metanet4j.sdk.bap.BapBaseTest Compatible with the following JavaScript code: https://github.com/icellan/bap/blob/master/src/id.ts#L436 https://github.com/icellan/bap/blob/master/src/id.ts#L456

2. Support for signing transactions with the private key corresponding to a BAP identity.
