Here we bring you the @RiscZero Special, covering the recent key announcements, technical breakthroughs, and essential updates in the @boundless_xyz ecosystem
@RiscZero has introduced OP Kailua Validity Mode - a solution that allows OP Rollups to gradually transition from optimistic proofs to full ZK proofs, without changing their core architecture or interrupting network operations: https://risczero.com/blog/RISC-Zero-OP-Kailua…
This approach enables teams to adopt the technology incrementally and without endangering users.
Validity Mode provides:
Finality in under one hour, eliminating the delays typical of the 7-day challenge period in Optimistic Rollups
A higher level of security: no arbitration is needed, and the system remains secure as long as there is at least one honest sequencer
Built-in permissionless sequencing with an optional “Vanguard” feature, granting safety guarantees by allowing an internal proposer a brief head start
Full compatibility with Stage 2 decentralization
Testing has shown that OP Kailua can already support high throughput at minimal cost. For example, cost modeling based on recent activity on @base demonstrated that Kailua Validity Mode can achieve transaction fees as low as $0.00012.
For projects prioritizing flexibility, a Hybrid Mode is also available. It allows the use of a ZK-based fraud-proof framework without committing to full Validity Mode. This gives rollups the opportunity to evaluate performance and economic feasibility in a live-like environment - and switch modes whenever they’re ready.
@RiscZero are also continuing to develop their zkVM infrastructure and have introduced an important update - formal verification of their RISC-V zkVM using the Picus tool developed by @VeridiseInc: https://risczero.com/blog/RISCZero-formally-verified-zkvm…
This update addresses one of the core challenges in the ZK space: eliminating the most common category of vulnerabilities - underconstrained bugs. These bugs occur when the circuit constraints are not strictly defined, allowing malicious provers to generate incorrect computations that still pass verification.
The new version, R0VM 2.0, provides:
Formal guarantees of determinism - meaning a strict, one-to-one correspondence between inputs and outputs in the circuit
Proven correctness of the Keccak accelerator and significant portions of the new RISC-V circuit
The ability to quickly and regularly re-verify all components after updates (less than 3 minutes to process tens of thousands of constraints)
Verification is performed using a hybrid approach that combines static analysis with SMT solving. This ensures that every computational step inside the zkVM is reproducible and the only valid result for a given input.
This level of transparency and reliability positions R0VM as one of the first zkVMs moving toward fully formalized computational security.
@RiscZero has partnered with @librecap to enable the RISC Zero zkVM to issue onchain credentials that preserve investor privacy while meeting regulatory requirements: https://x.com/RiscZero/status/1900559777400287528…
It also enables decentralized identities (zkDIDs), giving investors control over their compliance credentials in a secure and private system.
@0xEverly, Product Lead at @RiscZero, shared an article in which he explains how verifiable compute addresses major inefficiencies across industries reliant on opaque, outdated systems: https://x.com/0xEverly/status/1904934669121957905…
He outlines the benefits in efficiency, innovation, and data privacy, and explains how verifiable compute reduces reliance on intermediaries and protects sensitive data.
Jacob's article is a great starting point for anyone looking to understand the role of @boundless_xyz in enabling scalable, ZK-powered applications across blockchains by offering full-stack infrastructure for developers.
@boundless_xyz announced the Boundless House of ZK, jointly organised with @HouseofZK, which will take place on April 6th at the Hong Kong @festival_web3: https://x.com/HouseofZK/status/1904884652944302110…
Speakers include @1HowardWu, @Ismael_H_R, @anuragarjun, @0xEverly, and many more high-profile names covering a vast array of topics from applications of ZK to who owns the ZK narrative. The event will be live streamed from @HouseofZK - don't miss it!
