Additional Features and Improvements

  • Tic-tac-toe on-chain games now funded using an off-chain Ethereum-style faucet
  • Transaction format extended to support single transaction multisig
  • SDK now includes a fork of the LLVM compiler toolchain that includes an enhanced BPF backend
  • On-chain C programs can now return structs and pass them across translation units
  • Validators now do Proof of History verification
  • Banking code restructured to track multiple forks (though fork selection and rollback not yet implemented)
  • Lots of progress to replicator nodes (though not yet integrated into the data plane)
  • Migrate codebase to Rust 2018
  • Upgraded GPU code to CUDA 10.0

Breaking Changes

  • Transaction format is incompatible with previous releases. Expect this in all releases until mainnet launch.

Known Issues

  • ~10% drop in TPS compared to the latest Pillbox release

Release v0.10 - Pillbox

With this release we have increased our mean transaction throughput to 200k TPS while extending our transaction engine to load and interact with programs written in C. We execute programs using BPF, the same technique that the Linux kernel uses to run untrusted code for high-performance packet filtering and process sandboxing. Applied to blockchain, it means DApp developers can expect the same amazing runtime performance previously only available to the blockchain software itself.

100 186,808 460,587 1.318 14.398 10.834

Additional Features and Improvements

  • Added atomic batched transactions so multiple instructions can be included in a single transaction
  • Published Rust crate solana-sdk to implement built-in programs
  • Preview release of on-chain program solana-lualoader to load on-chain Lua programs
  • Down to zero known security vulnerabilities in all package dependences. Thanks cargo audit!

Breaking Changes

  • Transaction format is incompatible with previous releases. Expect this in all releases until mainnet launch.

Known Issues

  • Average finality times popped above 1 second. The validators on our testnet are having a bit of trouble keeping up with the speedy new leader.

Release v0.9 - Swamis

Just two weeks after our v0.8 Windansea release, the Solana team is proud to release the next major revision, v0.9 Swamis.

Major Features And Improvements

  • First release of our smart contracts SDK. Play tic-tac-toe on-chain!
  • First debut of "replicator" nodes that provably store ledger segments.
  • Fixed all known issues from the v0.8 testnet. It's rock solid, averaging well over 100k TPS.

TPS Report

Node Count Avg TPS Max TPS Avg Finality Max Finality
10 130,371 235,165 568ms 1.414s
25 123,356 240,309 624ms 1.595s
50 110,136 235,045 680ms 1.474s
100 116,849 242,730 732ms 2.068s

Breaking Changes

  • Transaction format, ledger format, and wire format for replication are incompatible with previous releases. Expect this in all releases until a mainnet launch.

Known Issues

  • None!

What's next

  • Proof-of-Stake leader rotation
  • Torrent-style ledger replication
  • Multi-threaded contract engine
  • User-defined smart contract interpreters
  • Faster, faster, faster!

Release v0.8 - Windansea

The Solana team is proud to release version 0.8.0 of our high-performance blockchain software. In this release, we introduce the LAMPORT smart contract engine, our biggest innovation since Avalanche replication. With LAMPORT (Language-Agnostic, Memory-oriented, Parallel-friendly, Optimized Run-Time), we can execute smart contracts concurrently, and written in the client’s choice of programming language. Furthermore, we demonstrate Solana’s built-in smart contract language Budget can target LAMPORT without any loss in performance. The two features that allow LAMPORT to work:

  • Client-owned memory identified by public keys. By declaring ownership upfront and separating the program’s state from the program, the runtime knows which contracts can safely be executed concurrently.
  • Solana’s blockchain-encoded VDF tells validator nodes at precisely what times they need to end up in the same state. Between those times, they are free to introduce non-deterministic behavior as-needed to improve execution times.

Major Features And Improvements

  • Initial support for web-based clients via JsonRPC
  • Accounts with state: forms the basis for Solana's smart contracts engine
  • Dynamic testnet deployment for Google Cloud SDK - run your own testnet!
  • 20% performance improvement over v0.7 in transactions per second
  • Improved metrics and network monitoring
  • Simpler and more robust rendezvous with gossip
  • Simpler and more consistent CLI interfaces

Breaking Changes

  • Network rendezvous and network ports have moved from hard-coded to ad-hoc
  • Transaction format, ledger format, and wire format for replication are incompatible with previous releases. Follow-on releases are also likely to break this.

Known Issues

  • Heavily trafficked testnets are suffering from our aggressive out of memory approach.
  • Server restart may fail on networks with heavy traffic with "LastIdNotFound" #1171
