Today, Aztec Labs is excited to share the winning proposal from the prover coordination protocol request for proposals (RFPs) - “Sidecar”. Additionally, we are announcing a formal request for comments period covering Aztec’s Sequencer Selection and Prover Coordination Protocols, key components of Aztec’s block production.
At the heart of Sidecar’s design is the decision to facilitate proving outside of the scope of the protocol, enabling integrations with various solutions, such as decentralized zero-knowledge proving marketplaces. Read the latest documentation on Aztec’s Block Production

Why Sidecar?
The Aztec Labs team, with input from various industry-leading experts, chose Sidecar over the various other proposals submitted (1, 2, 3, 4, 5, 6) due to its simplicity and ease of integration - very similar to the reasons the Fernet Sequencer Selection protocol was chosen during a previous RFP process.
Further, the decision to not enshrine a particular prover coordination protocol enables Aztec Labs to continue iterating on proving networks or marketplaces outside of the scope of the Aztec network’s traditional upgrade mechanisms - similar in spirit to Vitalik’s notion of “minimum viable enshrinement".
Additionally, not enshrining a particular protocol in this way allows the network to be fully compatible with a broad spectrum of options to prove a given block, including:
- vertical Sequencer-Prover integration, or
- third party zero-knowledge (zk) proving providers, or
Fully decentralized zk proving marketplaces
Through these various options, Aztec’s proving is fully permissionless and allows anyone to participate in a competitive marketplace for zero knowledge proof production.
"We are excited to collaborate with other projects that share our vision for decentralized zero-knowledge proving. If you are interested in partnering with us to build a better, privacy-enabled future, please reach out via email at bruno@aztecprotocol.com.”
