It anchors file and Git-commit timestamps to Bitcoin-backed attestations, producing small `.ots` proof files that can be checked independently later. ### 项目历史 Peter Todd announced OpenTimestamps in September 2016 as a scalable, trust-minimized, distributed timestamping scheme using Bitcoin. The design separates the timestamp proof format from any single web service: calendars aggregate commitments, Bitcoin supplies the public time attestation, and clients can later verify proofs against the blockchain. The client repository packages the everyday tooling around that protocol: stamping files, upgrading pending timestamps, verifying proofs, and integrating timestamps into PGP-signed Git commits. The Git integration work targeted a software-supply-chain problem: a commit signature proves who signed a commit, while a timestamp helps show when that signature existed. ### 采用历史 OpenTimestamps appealed to users who wanted blockchain-backed proof-of-existence without putting whole documents on-chain or trusting a single timestamping authority. Public calendar servers made ordinary timestamp creation cheap and fast, while local verification with Bitcoin Core kept the trust model understandable for security-sensitive users. The client remained niche compared with general signing tools, but it developed a small ecosystem of protocol implementations in Python, JavaScript, Java, and Rust. Its strongest adoption story is in release engineering, archival proof, research-notebook integrity, and Git-history timestamping rather than broad consumer file sharing. ### 使用方式 Users run commands such as `ots stamp`, `ots verify`, and Git wrapper commands to create proof files, complete pending attestations, and check that a file or commit existed before a Bitcoin block time. Verification can use a local Bitcoin Core node, including a pruned node, so the proof does not depend on the original calendar server staying online. The package’s `ots-git-gpg-wrapper` executable is especially package-nerdy: it composes Git signing, GPG signatures, and timestamp proofs so release commits can carry both identity and time evidence. ### 为什么软件包爱好者会关心 This package sits at the intersection of packaging, cryptography, and reproducible provenance. It is small, but it gives maintainers a way to attach time evidence to source releases, commits, and artifacts without inventing a full transparency log. ### 时间线 - 2016-09: OpenTimestamps was announced as a Bitcoin-backed timestamping protocol. - 2016-09: Git integration was documented as a way to timestamp PGP-signed commits. - 2020s: client release notes continued to refine Git extraction, cache locations, timestamp display precision, and verification behavior. ### Related projects - Related projects include opentimestamps-server for calendar services, python-opentimestamps for protocol primitives, java-opentimestamps, javascript-opentimestamps, Bitcoin Core, GnuPG, and Git. ### 来源 - - - - - - ## 安全说明 没有找到 opentimestamps-client 的匹配本地密钥处理 manifest。软件包元数据仍在此发布，以便未来覆盖拥有稳定的软件包 URL。 ## 源数据库详情 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** opentimestamps-client - **Version Scheme:** 0 - **Revision:** 4 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 其他软件包管理器记录 - Nix - opentimestamps-client: normalized package name match | nixpkgs package indexes: pkgs/by-name/op/opentimestamps-client/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## 相关链接 - [Source-control packages](https://pkg.so/zh-hans/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/zh-hans/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/zh-hans/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Security and crypto packages](https://pkg.so/zh-hans/security-crypto-tools/) - Matched security, identity, cryptography, password, signing, or certificate metadata. - [python@3.14](https://pkg.so/zh-hans/brew/python-3-14/) - Runtime dependency declared by Homebrew. - [smimesign](https://pkg.so/zh-hans/brew/smimesign/) - Shares pkgdb curated category or tags: cli, git-signing, security. - [openssl@3](https://pkg.so/zh-hans/brew/openssl-3/) - Shares pkgdb curated category or tags: cli, security. - [gnutls](https://pkg.so/zh-hans/brew/gnutls/) - Shares pkgdb curated category or tags: cli, security. - [p11-kit](https://pkg.so/zh-hans/brew/p11-kit/) - Shares pkgdb curated category or tags: cli, security. - [gnupg](https://pkg.so/zh-hans/brew/gnupg/) - Shares pkgdb curated category or tags: cli, security. - [krb5](https://pkg.so/zh-hans/brew/krb5/) - Shares pkgdb curated category or tags: cli, security. - [nettle](https://pkg.so/zh-hans/brew/nettle/) - Shares pkgdb curated category or tags: cli, security. - [libcap](https://pkg.so/zh-hans/brew/libcap/) - Shares pkgdb curated category or tags: cli, security. - [censys](https://pkg.so/zh-hans/brew/censys/) - Both packages touch the same language runtime or ecosystem.
