Internalising the Identity Primitive: Cryptographic Individuality for an Autonomous Agent on a Public Blockchain
- 用私钥直接生成神经网络权重，实现身份与密钥的确定性绑定。
- 在2.36天内完成链上运行，每步验证成本可控，身份被篡改即遭拒绝。
- 适合研究去中心化智能体、可信计算和链上身份安全的开发者。
公共区块链上的软件代理积累权威与经济利益，引发其“个体性”如何定义的问题。本文提出将代理身份的密钥-权重绑定信任根，从硬件、操作者或封装层转移至密码学假设，由固定实现（保持活性、密钥保管、预言机信任及底层软件栈为外部）强制执行。我们在Solana测试网设计并部署了一个智能体，其神经网络权重由私钥决定。该绑定在创世时以零知识方式承诺，每次状态转换均重新校验，并由代理签名写入不可分叉的链上历史；在演示级扩展中，协议对每个周期从密钥派生的经济账户扣除协议规定的代谢成本，引入消费侧经济可行性约束。实验表明，该代理完成2.36天链上运行，两次主机恢复但无状态转换被拒绝，每步验证开销有限；替换底层组件被链上拒绝，不同密钥的代理如预期分叉，相同密钥对照组则保持一致。据我们所知，这是首个公开发布的链上智能体，其身份原语本身是可逐次验证的密码学不变量。该状态转换时间不变量实现了Suzuki 2026年《人工外在性》框架提出的密码学个体性。
原文摘要 · Abstract (English)
A software agent on a public blockchain accumulates authority and economic stakes, raising the engineering question of what makes it count as an individual. The paper's central contribution is a shift of trust root for the key-to-weights binding of agent identity: from hardware, operator, or wrapper trust to cryptographic assumptions enforced by a pinned implementation (liveness, key custody, oracle trust, and the underlying software stack remain external). We design and deploy on Solana devnet an agent whose neural-network weights are a deterministic function of its private key. The binding is committed in zero knowledge at genesis, re-checked against that commitment at every state transition, and signed by the agent into an on-chain history unforkable once finalized; in a PoC-tier extension, a protocol-imposed metabolic cost is debited each cycle from a key-derived economic account, adding a consumption-side economic-viability constraint to the key-history-economy triple. Empirically, the agent completes a 2.36-day on-chain run with two host-side resumptions but no rejected transition, at bounded per-transition verification cost; a substituted substrate is rejected on chain, and independently keyed agents diverge as predicted while a same-key control stays at zero. To our knowledge, this is the first published on-chain agent whose identity primitive is itself a cryptographic invariant re-checked at every state transition. The resulting transition-time invariant instantiates the cryptographic individuality proposed by Suzuki 2026's Artificial Externality framework.
