Solana's RPC 2.0 Gets Concrete: Superbank and Cloudbreak as Open-Source Modules
The RPC 2.0 initiative ships its first modules: Superbank makes the entire Solana ledger queryable in milliseconds, Cloudbreak indexes account reads — open-source, built by Triton with Helius, Jupiter, Anza, and the Solana Foundation.
What Happened
The RPC 2.0 initiative announced in April is shipping its first concrete modules. RPC 2.0 is, per Solana, built jointly by Triton One, Helius, Jupiter, Anza, and the Solana Foundation. The idea behind it: read access is pulled out of the Agave validator client and moved into independent, open-source modules. The first of these are now here — Superbank and Cloudbreak.
Superbank: the Entire Ledger in Milliseconds
Superbank is a new Rust backend that ingests the full Solana history into a ClickHouse database and serves it over high-performance JSON-RPC. It replaces the Bigtable connection previously used for historical queries. Per Triton, the code has been open-sourced under the AGPL license — anyone can run, audit, or extend it.
The speedups Triton cites for common queries:
- getSignatureStatuses: 1,885 ms → 49 ms (about 38×)
- getSignaturesForAddress: 245 ms → 50 ms (about 5×)
- getTransaction: 460 ms → 138 ms (about 3.3×)
- Head-cache queries resolve, per Triton, in under one millisecond without a database round-trip.
Cloudbreak: Indexed Account Reads
Cloudbreak is the counterpart for account queries. It serves methods like getProgramAccounts, getTokenAccountsByOwner, and getTokenAccountsByDelegate from PostgreSQL indexes that build themselves automatically from an app’s actual query traffic — decoupled from the Agave validator. Adaptive indexes thus replace the full database scans previously required.
Context
For Solana, this is a step toward a specialized, modular read layer instead of a validator that has to do everything at once. Faster and cheaper read access directly affects wallets, explorers, and analytics tools whose transaction histories could load sluggishly before. That the modules are open-source also reduces dependence on individual providers.
What to Watch
- How quickly wallets and explorers switch to the new read layer
- Which further RPC 2.0 modules follow and when the stages go into production
- Whether the open-source release leads to more independent RPC operators
