A community-led second Mina client, checked against the OCaml node by replaying the chain, checking proofs and comparing fork choice.
Under a minute
Devnet sync from scratch
From an empty data directory, via OCaml peers.
A few minutes
Mainnet sync from scratch
Most of it is the ledger download from OCaml peers.
Seconds
Restart to synced
The node replays its saved chain.
Under 1 GB
RAM for a devnet full node
A few hundred MB once synced. It runs on a Raspberry Pi.
What it is
Mina has one working node implementation, OCaml. With a second, a bug in one no longer has to be a bug in every node.
Syncs mainnet and devnet from OCaml peers and follows the tip.
Its blocks reach devnet's best chain. Not yet on mainnet.
Block 579510 (opens in a new tab)Produces the transaction SNARK work that block producers buy. Devnet producers buy its work.
The full node in a browser tab, with nothing to install. It follows this native release shortly.
Native and web
Native
A native daemon for every role, with a GraphQL API and a feed to OCaml's archive.
Mainnet
Replayed block by block
Every staged-ledger hash matched OCaml.
Archive
Feeds OCaml's archive
Its archive matched one fed by OCaml on every main-chain block.
Both ways
OCaml syncs from it
A fresh OCaml node syncs with the Rust node as its only peer.
WebAssembly
The same Rust code, compiled to WebAssembly. It syncs mainnet, verifies proofs, and signs and sends transactions over WebRTC.
A few MB
Download
WebAssembly, compressed.
No install
Runs in a tab
Open the page and it syncs.
Block producer
From the browser
It produced and proved a devnet block in a tab.
Get started
Download the archive for your CPU or run the Docker image, then open its dashboard.
Linux builds for x86-64 and ARM64, with the devnet prover circuits inside.
For x86-64 and ARM64. With Docker Desktop it also runs on macOS and Windows.
The browser node is a separate build.
Build the node and dashboard from the public source.
