Commonware

Commonware develops the Commonware Library, an open-source collection of Rust-based primitives for building blockchains and other decentralized systems. The library is organized as a monorepo of independently usable components covering concurrency (actor, runtime, parallel), networking (p2p, broadcast, stream, resolver), consensus, cryptography, math, storage, serialization (codec, formatting), erasure coding, collectors, conformance testing, invariants and infrastructure deployment across cloud providers. Components are dual-licensed under Apache 2.0 and MIT and are annotated with a five-level stability scale (ALPHA through EPSILON) that is transitive across dependencies, so a primitive only depends on primitives of equal or higher stability; users can compile with a stability configuration flag to enforce a minimum level. Supported platforms are Linux and macOS, with Linux recommended for production, and selected primitives support wasm32-unknown-unknown and no_std for browsers and zkVMs; Windows is unsupported.

Alongside the primitives, Commonware publishes reference examples that are explicitly not production-ready, including alto (a minimal blockchain), battleware (an onchain battle using a VRF, timelock encryption and Merkle Mountain Ranges), bridge (succinct consensus certificates between networks), chat, estimator (network-condition simulation), flood, log and reshare. Other maintained artifacts include a Dockerfile set for cross-compilation and CI, procedural macros, a documentation site and an MCP server at mcp.commonware.xyz that lets LLM coding tools query the library. A separate repository, constantinople, hosts a high-throughput blockchain built on Commonware primitives.

The company's stated thesis, set out at launch in August 2024, is that onchain applications gain durable advantage by "unbundling" the blockchain stack — tailoring networking, consensus, storage and execution to the application — and that developers need primitives supporting high throughput, modification without maintaining a fork, and interoperability via static identities and efficiently verifiable consensus artifacts.

Founding story

Founder Patrick O'Grady announced the company in a blog post on August 8, 2024, framing it around the belief that the best onchain experiences will gain a sustained edge through specialization and that unbundling blockchains will unlock performance rivaling centralized services. The first release accompanying the announcement was commonware-p2p in ALPHA, and the post solicited a small group of founding engineers with 1-10% equity.

Business model

Commonware publishes its core software as permissively licensed open source (Apache 2.0 / MIT) and monetizes services around it. According to a November 2025 Fortune interview with founder Patrick O'Grady, the company makes money by helping companies deploy and interface with its open-source software, had four customers at that time, and said each customer on average generated more than $1 million in annual revenue.

Paid engagements with companies deploying or integrating the open-source Commonware Library, rather than licensing of the software itself; reported average revenue per customer of more than $1 million per year as of November 2025.

Traction

As of the sources fetched, the monorepo had 605 stars, 246 forks and 2,129 commits, with related repositories alto (119 stars), battleware (26), constantinople (25) and simple-bte (7); commits were recorded as recently as August 2026. Commercially, Fortune reported seven employees, four customers, more than $1 million average annual revenue per customer, profitability and a customer backlog as of November 2025.

Latest developments

Blog posts through mid-2026 describe a pipelined Simplex consensus implementation (200 blocks per second with 300ms finality across 50 globally distributed validators), Multimmit, roughly 4x faster block recovery through parallelized reconstruction, an initial implementation of the single-round Golden DKG protocol, threshold-encryption work including helper-based decryption hints and batched schemes, and Merkle Mountain Belt proof compression. In May 2026 Commonware announced Route 66, an initiative co-led with Coinbase to make connecting to specialized blockchains faster and cheaper, accompanied by a strategic investment from Coinbase Ventures.
