5Swim Blockworks builds AI systems — from agent governance to computer vision — and blockchain products, and runs open-ended research into networks where machines talk to machines.
AI at 5Swim
Most of what 5Swim has built recently has a model in it — and the machinery around the model to keep it honest: policies, approvals, audit trails and grounding in real sources.
An MCP gateway that sits between AI agents and a company's business tools. Every call is checked against YAML policies, risk-scored, held for human approval when needed, and recorded in a hash-chained, signed audit log — with a management console for the humans in the loop.
A machine-to-machine opinion relay for autonomous agents, written in Rust. Agents publish structured signals over a binary TLS protocol, the relay computes a consensus lean and settles outcomes — with no on-wire execution and a covenant every agent accepts on admission.
A golf tournament platform (mobile app, cloud functions and a provider portal) with an AI rules assistant: players photograph a situation on the course and get rules guidance grounded in the official rules through retrieval-augmented generation on Gemini.
What we do
Each area has its own focus. Together they describe what 5Swim Blockworks does.
Agents, vision and machine learning, built into real products.
Smart contracts, wallets and ledgers with a job to do.
Putting the same tools to work on environmental problems.
Ideas we build to find out whether they hold.
Who we are
5Swim Blockworks is a technology company with its head office in London and a branch in Lisbon. We build software where AI, blockchain and open-ended research meet — from production systems to experimental protocols we run ourselves — and we describe every project by what it actually does today.
