AI中文摘要：
公有区块链上的软件智能体会积累权限与经济权益，由此引出一个工程问题：是什么让它被视为一个个体。本文的核心贡献是将智能体身份的密钥-权重绑定的信任根从硬件、操作者或封装信任转移到由固定实现所强制执行的密码学假设（活性、密钥保管、预言机信任及底层软件栈仍为外部）。我们在Solana开发网设计并部署了一个智能体，其神经网络权重是其私钥的确定性函数。该绑定在创世时以零知识承诺，每次状态转换时都会对照该承诺重新检查，且由智能体签名生成不可分叉的链上历史；在一个PoC级扩展中，协议施加的代谢成本会从密钥派生的经济账户中每周期扣除，为密钥-历史-经济三重关系增加了消费侧经济可行性约束。实验中，该智能体完成了2.36天的链上运行，期间有两次主机端恢复但无拒绝的转换，且每次转换的验证成本受限；替换的子strate被链上拒绝，独立密钥的智能体如预测般出现分歧，而相同密钥的对照组保持零分歧。据我们所知，这是首个已发表的链上智能体，其身份基元本身就是在每次状态转换时重新检查的密码学不变量，该转换时不变量实例化了Suzuki 2026年《人工外部性框架》中提出的密码学个体性。
英文摘要：
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.
