TapeOut 生态出现两项比特币方向实验Two Bitcoin-oriented TapeOut experiments surface
10月22日 TapeOut 观察日报提到两项早期实验：Bitcoin-Keyed Holders 草案探索用比特币钱包签名控制 EVM 侧持有人合约，让 BTC 密钥用户持有和授权电路，而无需先把 BTC 搬到另一条链；UCO 开源实验把电路定义放入铭文、状态放入 UTXO，由索引器检查状态转换，电路计算规则由索引器验证，并非由 Bitcoin 共识直接执行。日报称两条路径均处早期，前者尚未在公共链部署。The Oct 22 TapeOut observation daily covered two early experiments. The Bitcoin-Keyed Holders draft explores using Bitcoin wallet signatures to control EVM-side holder contracts, letting BTC key holders own and authorize circuits without moving BTC to another chain. The UCO open-source experiment puts circuit definitions in inscriptions and state in UTXOs, with an indexer checking state transitions; circuit computation rules are verified by the indexer rather than executed by Bitcoin consensus. The daily said both paths are early-stage, and the former has not been deployed on a public chain.
