Architecture overview

vlayer execution spans across three environments, each written in respective technologies and consisting of related components:

• browser (js)
  • javascript SDK - thin wrapper around the vlayer JSON-RPC API
  • browser plugin - used for notarization of TLS Connections
• server infrastructure (rust)
  • prover server - exposing vlayer functionality via vlayer JSON-RPC API
  • chain proof cache - http server used as a cache for proofs of inclusion of a block in a chain
  • TLS Notary server - used to notarize TLS connections
  • DNS Notary server - used to notarize DKIM DNS records
  • workers - used to perform actual proving
• blockchain (Solidity)
  • on-chain smart contracts - used to verify proofs

All the above components can be found in the monorepo. It also contains sources of this book.
