Proof-of-Inquiry Gateway for CKB

Developer / Team

RadhikaChain / RadhikaChain Research

Independent open-source engineering project focused on verifiable agent infrastructure, blockchain interoperability, privacy-preserving evidence, and machine-to-machine services.

Project Description

We are building an open-source Proof-of-Inquiry (PoI) infrastructure for AI agents and blockchain services.

The system allows an agent to request an operation, collect evidence from multiple sources, verify the resulting state, and produce a cryptographic proof that the operation was executed under a defined policy without requiring all underlying private data to be published.

The CKB-focused prototype will implement a CKB evidence/attestation layer that connects PoI receipts with CKB transactions/cells and provides a reproducible verification interface for agents.

The project will use Rust where appropriate and expose the resulting capabilities through structured APIs/MCP-compatible interfaces.

The prototype is intentionally scoped as an infrastructure and verification project rather than a token speculation or trading project.

CKB Ecosystem Relevance

The project will provide an open-source verification interface that allows agents and CKB applications to consume verifiable cross-chain/process evidence.

The prototype will explore:

  • CKB-native anchoring of PoI commitments;

  • verification of external evidence through CKB cells/transactions;

  • reproducible Rust tooling;

  • agent-facing discovery and verification interfaces;

  • Bitcoin and RadhikaChain evidence references;

  • privacy-preserving commitments instead of publishing sensitive source data.

This creates a reusable infrastructure component that can be consumed by CKB applications, wallets, agent systems, and Web5 services.

Deliverables

  1. Open-source PoI-to-CKB adapter.

  2. Rust verification library.

  3. CKB testnet demonstration.

  4. PoI evidence schema.

  5. CKB commitment/attestation schema.

  6. Agent/MCP-compatible verification API.

  7. Reproducible deployment package.

  8. Automated integration tests.

  9. Security and failure-mode documentation.

  10. Bilingual technical documentation.

  11. Public GitHub repository.

  12. Online demonstration.

Validation Plan

The prototype will be tested against:

  • valid evidence;

  • modified evidence;

  • replayed evidence;

  • invalid CKB transaction references;

  • inconsistent commitments;

  • service restart;

  • network interruption;

  • duplicated requests.

The goal is to demonstrate that invalid evidence is rejected deterministically while valid evidence remains independently verifiable.

Estimated Timeline

8 weeks.

Weeks 1–2

CKB adapter architecture, schemas, Rust interfaces, PoI mapping.

Weeks 3–4

CKB anchoring and verification implementation.

Weeks 5–6

Agent/MCP interface, testnet deployment and automated validation.

Weeks 7–8

Security testing, documentation, demo, public release and user feedback.

Funding Requested

Up to $2,000 equivalent.

Suggested allocation:

  • $600 — development and integration infrastructure;

  • $400 — testing and deployment environments;

  • $300 — CKB testnet/integration tooling;

  • $300 — security and verification testing;

  • $200 — documentation/demo infrastructure;

  • $200 — user testing and feedback.

Expected Outcome

At completion, the ecosystem will have a working open-source prototype demonstrating how an agent can request verification, obtain a PoI commitment, anchor relevant evidence to CKB, and independently verify the result.

The project will provide reusable infrastructure rather than a closed application.

Long-Term Direction

The prototype can later evolve toward:

  • CKB ↔ Bitcoin evidence;

  • CKB ↔ RadhikaChain verification;

  • agent-to-agent machine payments;

  • RWA evidence;

  • privacy-preserving compliance proofs;

  • decentralized agent infrastructure.

These are future directions and are not required for the initial Spark deliverable.

开发者 / 团队

RadhikaChain / RadhikaChain Research

一个专注于可验证 Agent 基础设施、区块链互操作、隐私保护证据以及机器间服务的开源独立研发项目。

项目简介

我们正在构建一个面向 AI Agent 和区块链服务的开源 Proof-of-Inquiry（PoI）基础设施。

PoI 允许 Agent 发起请求、从多个来源收集证据、验证相关状态，并生成一个密码学证明，以证明相关操作是在规定策略下正确执行的，而无需公开所有底层敏感数据。

本次 Spark 项目将重点实现 CKB 侧的证据与证明适配层，使 PoI receipt 能够与 CKB transaction/cell 建立可验证关系，并向 Agent 提供可复现的验证接口。

项目将主要使用 Rust，并通过结构化 API/MCP 兼容接口提供相关能力。

本项目定位为基础设施和验证技术项目，而不是代币投机或交易项目。

对 CKB 生态的贡献

项目将提供一个开源验证接口，使 Agent 和 CKB 应用能够使用可验证的跨链及流程证据。

原型将探索：

  • 基于 CKB 的 PoI commitment anchoring；

  • 利用 CKB cell/transaction 验证外部证据；

  • 可复现的 Rust 工具；

  • 面向 Agent 的发现与验证接口；

  • Bitcoin 与 RadhikaChain 证据引用；

  • 使用 commitment，而不是公开敏感原始数据。

该基础设施可以被 CKB 应用、钱包、Agent 系统以及 Web5 服务复用。

计划周期

8 周。

申请资金

最高 $2,000 等值资金，用于开发、测试、部署、验证、安全测试、文档及用户反馈。

预期成果

项目完成后，将形成一个可公开验证的开源原型，使 Agent 能够：

请求验证
→ 获得 PoI commitment
→ 在 CKB 上锚定相关证据
→ 独立验证最终结果。

长期方向

未来可以扩展到：

Bitcoin ↔ CKB
CKB ↔ RadhikaChain
Agent-to-Agent machine payments
RWA evidence
privacy-preserving compliance proofs
decentralized agent infrastructure

以上扩展不是本次 Spark 第一阶段的必要交付内容。
