Testnet #1 (released Nov 2024)

Codename: Archimedes

SDK

• Released Rust SDK v0.13+

• First Web demos running a Linera client in the browser

• Blob storage for user data

Core protocol

• Blob storage for application bytecode and user data

• Multi-user chains (e.g. used in on-chain game demo)

• Initial support for fees

Infrastructure

• Fixed number of workers per validator

• Onboarding of 20+ external validators

Testnet #2 (released Apr 2025)

Codename: Babbage

SDK

• Official Web client framework

• Support for native oracles: http queries and non-deterministic computations

• Support for POW public chains

• Simplified user and application addresses

Core protocol

• More scalable reconfigurations

• No more "request-application" operations

• Bridge-friendly block headers compatible with EVM signatures

Infrastructure

• Better hotfix release process

• Support for resizing workers offline

Testnet #3 (released Sep 2025)

Codename: Conway

SDK

• Wallet connect (signing demo with external wallet)

• Event streams (deprecating pub/sub channels)

• Experimental support for EVM

• Compatibility with EVM addresses

Core protocol

• More scalable client with partial chain execution and optimized block synchronization

• Execution cache for faster server-side and client-side block execution

• Simplify chain creation and support externally created microchains

Infrastructure

• High-TPS configuration

• Software service to support block indexing

Testnet #4

SDK

• Stable support for EVM

• Transaction scripts

• Application upgradability

Core protocol

• Protocol upgradability, including block format, virtual machines, and system APIs

• Governance chain

• Final tokenomics and fees

• Storage durability

Infrastructure

• Network performance measurements and validator incentives

• Security audits

Mainnet and beyond

SDK

• Account abstraction and fee masters

• Linera light clients for other contract languages (e.g. Solidity, Sui Move)

Core Protocol

• Permissionless auditing protocol

• Performance improvements

Infrastructure

• Block indexing and block explorer

• Walrus archives

• Support for dynamic shard assignment and elasticity

• Geographic sharding

• Support for more cloud vendors

• Native bridges
