Following our exciting Eden mainnet upgrade back in December 2023, which introduced upgraded security features, performance optimization, and increased functionality of the network, there are always more developments to be made!

The Oasis team proudly announces that validators have voted to activate the highly anticipated Oasis Core 24.0 features. The voting concluded with an impressive 76% of the voting stake in favor of the proposal. The upgrade is scheduled for epoch 33777 (approx. Wed, 24 Jul 2024 08:10:56 GMT). After this epoch, Oasis Core 24.0 features will activate, and the Eden 24.0 upgrade will be completed.

A heartfelt thank you to all validators who participated in the voting process!

This upgrade brings key features such as support for off-chain runtime logic (ROFL), enhanced forward secrecy through proactive secret sharing in the key manager (CHURP). A cache-efficient PathBadger block storage engine, confidential computation by any observer node supporting the TEE, and more are also included as key network improvements.

Officially launched on May 13, many additional Oasis Core 24.0 features will be enabled gradually via consensus governance proposals in the coming months, so the excitement doesn’t stop here.

To stay up to date with what the engineering team has been doing between Eden upgrade and Consensus24, check out our engineering updates from January, February, March, April and May!

Eden 24.0: Main Features

In an effort to Decentralize All The Things, Runtime OFf-chain Logic (ROFL) has been added essentially to unlock smart privacy for AI.

It adds arbitrary off-chain logic, leveraging Oasis’s existing decentralized execution, distribution, and remote attestation infrastructure. This feature enables various use cases, including oracles, bridges, light clients, complex data workloads, intent solvers, and autonomous AI agents. If you’re interested in reading more, check out ADR 24. More documentation and an initial version of the SDK for developing ROFL applications will be released soon.

Good news for node operators: Nodes will now run faster and require less disk space. PathBadger storage backend optimizes storage by changing the on-disk storage format for trie nodes, improving locality when iterating over the trie and reducing database size and compaction time. This backend is currently experimental and can be enabled with the configuration option storage.backend set to pathbadger, requiring a complete resync with an empty database.

Showing our commitment to continuously developing our security standards, Oasis will become even more secure. For those looking for a proactive secret sharing in key manager runtimes, CHURP introduces an option for key manager nodes to only hold shares of the master secret in encrypted memory. This enhancement provides stronger security guarantees, as compromising a single node only reveals a single share.

To break the system, an adversary would need to compromise multiple nodes at the same time, which should be extremely difficult, especially if nodes are running on different TEE platforms. Client-side support for secret reconstruction and key derivation will be included in an upcoming release.

Eden 24.0: Governance Proposal Activation

Aside from Oasis Core 24.0 main features, with Eden 24.0 we just activated more features via a governance vote:

• Increased Transaction and Block Sizes: To accommodate larger node registrations required by the DCAP remote attestation scheme, especially when nodes run multiple runtimes.
• CHURP Key Manager Instances: Enabling consensus-layer logic for managing CHURP key manager instances, allowing key manager runtimes to utilize CHURP.
• Bug Fix for Delegators: Resolving the issue that prevented delegators from voting on governance proposals without an entity registration.
• Human-Readable Metadata: Adding titles and descriptions to future governance proposals, enhancing visibility in block explorers and governance dApps.
• Multi-Sig Vault Service: Introducing a simple multi-sig vault service to the consensus layer.

What’s Next?

Bringing key features such as ROFL continues Oasis’ commitment of extending smart privacy to more than just Web3, but to decentralized AI and more. We believe that “the future is decentralized, trustless and censorship-resistant development of applications in AI, DeFi, Gaming, DAO voting, DIDs – powered by interoperable, performant, confidential computation,” and this update is the next step in making the Oasis Vision a reality!
