Latest Protocol Releases

This release unlocks native execution of smart contracts in blackbox tests for the first time. That means you can now test your code against real contracts, even without their source, and simulate realistic, multi-contract behavior. 

‍

It also adds Rust 1.87 support, experimental gas metering, Wasmer 6 support, and a streamlined build system.

Greetings, MultiversX Builders!

The Andromeda Upgrade (v1.9.6, MIP-25) is ready for prime-time, marking the first giant leap toward sub-second finality. By removing confirmation blocks the network’s time-to-finality is slashed in half, while a full 400/400 validator consensus group, Equivalent Consensus Proofs, optimised cross-shard execution and lighter cross-chain proofs dramatically raise security, throughput and developer ergonomics.

Key highlights

• Instant finality – confirmation blocks eliminated → 2 × faster finality (MultiversX Agora )
• 400/400 consensus per shard – single-shot majority + fairer rewards MultiversX Agora
• Equivalent Consensus Proofs – any node can finalise a block, zero equivocation risk MultiversX Agora
• Cross-shard in three blocks – execution path cut from six to three steps (2 × faster) MultiversX Agora
• Slimmer cross-chain proofs – fixed validator set once per epoch, smaller payloads MultiversX Agora

mxpy v10 contains a few changes compared to the previous version that we'll go through below. The changes consist of some breaking changes with some things being removed, but also some new features and improved usability.

This release brings major refactoring to enhance robustness and ensure alignment with specifications.

Now, both the Python and JavaScript SDKs share a common design, simplifying cross-language development for builders.

We're rolling out a new upgrade for mainnet validator nodes. With this patch release, the 'Protocol sustainability rewards' address, currently a standard single-key wallet, is being migrated to a newly created multisig for greater security and control distribution. Since the destination address is configurable, the migration requires a network upgrade.
