Linera Announcements

⚡ Partnership Announcement: Space and Time (SxT)

Linera is partnering with Space and Time to bring ZK coprocessing to our ecosystem. This enables seamless integration of data from onchain + offchain sources, enhancing scalability & real-time capabilities for devs.

🌐 Integrates real-time, verified data from multiple blockchains
⚡ Enables limitless proof-verification operations for advanced use cases

Experience it yourself with the Airdrop Demo proof-of-concept app. This will let users claim tokens by providing ZK-proven evidence of holding specific testnet currencies like ETH at certain times:
https://github.com/linera-io/airdrop-demo

SxT is going to join us for the Community Hour this week, and set a reminder for an in-depth discussion about the partnership next month.

Together with Space and Time, we’re bringing Web2-level scalability to Web3—while maintaining the security and trustlessness that are core to our vision.

💻 Release of the DevNet SDK v0.12

⚙️ Scaling applications using microchains
Applications can now share data across chains in an easier and cheaper way thanks to data blobs. We also improved pub-sub channels with real-time data subscriptions for better scalability.

⚡ Speed is the key
We reduced storage loading times and now compress Wasm bytecode for smoother, faster apps. We improved multi-user chains to enable shared, interactive states—perfect for games, auctions, and swaps—unlocking new onchain app possibilities.

🪨 Making applications more reliable
Cross-chain messages sent from a same transaction and to the same receiver are now delivered atomically together, keeping application states more consistent and reliable.

🚀 Announcing the Linera SDK v0.11 for Rust
The SDK has been simplified and extended in many ways to make it easier to build a wide variety of applications.
https://forum.linera.io/t/releasing-linera-sdk-v0-11/221

🔧Wasm bindgen and VM upgrade
We rolled out a new generic framework to generate API stubs for Wasm containers, called “Witty”. This means that Wasm-compatible source languages supported by wit-bindgen will be easier to support in the future. This change also allowed us to upgrade to Wasmer v4.

👋 API Simplifications
We improved naming and made applications control their persistent state more explicitly. This allowed us to remove the custom test runner for Wasm. We also stopped using "Result" to manage errors in contract APIs.

🏁 New features
Application services can now access the Internet, as showcased by the new LLM Stories example. We also added an experimental support for HTTP queries in contracts, using a new oracle mechanism. Initial support for Ethereum interoperability was added, which will make use of this feature.

🔧New examples
We added instructions to use the AMM application for atomic swaps between two users using a shared chain. We also added an AI demo where the service part of an application can run an LLM model to generate short stories.

🔀 Core Protocol
We made a configurable policy for accepting/rejecting incoming messages. We added the commands linera wallet forget-keys and forget-chain. We made progress in the support of fallback leaders and public chains.

🧪 Ready to test your apps on the new SDK? Instructions to deploy applications on the new corresponding Devnet instance (devnet-2024-05-07) can be found on https://linera.dev

💡 Have questions or feedback? Drop us a reply in the repo, community Telegram chat (t.me/linera_official), or on the forum. We love hearing from our growing developer community and are here to help!

🚀 Announcing the Linera SDK v0.10 for Rust
This latest release includes important changes with the goal of making Linera applications simpler to write.
https://bit.ly/linera-sdk-v0-10

🔧 Improved framework to define WASM application states: We separated execution states from the storage state. Now, applications directly define types for 'Contract' and 'Service' execution traits, improving the definition of non-persistent runtime state.

👋 Sunsetted *Context arguments: We've replaced these with a runtime object for a cleaner and more efficient handling of callbacks in the 'Contract' and 'Service' traits.

🏁 Enhanced Smart Contract execution: With a defined lifetime for contract execution states via the new 'finalize' method, applications are now more efficient and capable of tracking transaction activities more effectively.

This new 'finalize' method, along with removing the experimental 'sessions,' has streamlined contract functionality, making it easier to implement features like flash loans without the need for undocumented concepts.

🔀 Simplified contract interface: We've merged operations and application calls into a single, clearer concept. This change makes code writing simpler and clarifies the purpose of public and private entry-points.

🧪 Ready to test your apps on the new SDK? The latest Linera Devnet (2024-03-26) instance is here for you to explore all these features in action. Try it out and see how v0.10 of the SDK can enhance your Linera application: https://bit.ly/linera-devnet-2024_03_26
