Smart Contracts via Move

Waimea v0.17.0

We're proud to announce the integration of Libra's Move smart contract language. It's now possible to deploy third party Move modules to Solana's beta testnet and send transactions to make payments. Moreover, all transactions execute in parallel, regardless if implemented in Rust, C, or Move.

Major Features And Improvements

• Embedded Libra's Move VM
• Improved parallel transaction processing via "credit-only" accounts
• Reduced block generation time from 800ms to 400ms

Replicators

Trestles v0.16.0

We're proud to announce our first release of replicator clients. With replicators there are now three ways to get rewarded for supporting a Solana cluster: validators, stakers and replicators. Validators progress the ledger, stakers give validators credibility by delegating stake to them, and replicators provide ledger storage. Together we see mainnet on the horizon!

Major Features And Improvements

• Proofs of Replication submitted to validators from new replicator clients
• Cross-platform client support
• Improved support for on-chain programming using Rust and BPF
• Automatic congestion control with dynamic fees
• Native token inflation

TPS Report

Node Count	Avg TPS	Max TPS	Avg Confirmation	Max Confirmation

25	70,058	123,272	6.74	14.8

Performance Metrics Methodology

Additional Features and Improvements

• Fast validator restart via bank snapshots
• Improved security via data plane randomization
• Proof of History generation and verification enabled on public testnet
• GPU support for Proof of History verification
• Inflation-based rewards for validators

Known Issues

• Validators that start from a snapshot report "solana_vote_api::vote_state] dropped vote Vote" warnings. See #4817 for more
• Wallet-sanity is failing for high number of node testnets (>50)

v0.15.3

• Prevent validator from panicking upon receiving malformed Transactions
• Correctly handle fullnode.sh --identity flag on testnet restart
• Update to Rust 1.35.0

v0.15.2

• Avoid sudo when using solana-install run validator.sh ...
