Introducing Kailua: A hybrid architecture that gives OP chains 1-hour finality without the higher cost of constant ZK proving.
2/ Today, the rollup landscape offers two different approaches:
→ Optimistic rollups: Low costs but 7-day finality
→ ZK rollups: Fast finality but high proving costs
Kailua introduces an innovative third option, combining the strengths of both.
3/ Built on OP's upcoming Kona suite, Kailua delivers what teams need:
→ Fast finality: Settle in under 1 hour
→ Low costs: Only prove during disputes
→ Easy integration: Full OP Stack compatibility
4/ Breaking down Kailua's cost and compatibility advantages:
5/ Kailua will let you control your path to full ZK:
Start with occasional validity proofs, increase frequency over time, and transition to full block-by-block proving when ready.
Your chain, your pace.
6/ Kailua will be supported by all major rollup-as-a-service providers including @conduitxyz, @alchemyplatform, @calderaxyz, @gelatonetwork , @alt_layer, @0xZeeve.
3/ Our partners are already leveraging Steel's power.
One app:
- Processed 400,000 SLOADs in a single contract call
- Saved 1.2 billion gas (equivalent to 30 blocks of execution)
- All proven with just one execution proof
This is not small improvement. It's a paradigm shift.
Introducing Boundless: The Verifiable Compute Layer
Unlimited execution. Global composability. On-demand scaling.
For every developer. On any chain.
2/ Boundless leverages ZK to enable verifiable off-chain execution for any chain.
This means any application can be built off-chain while inheriting blockchain security.
No block/txn/execution limits. Only boundless possibilities.
3/ Boundless will bring forth a new era of advanced & expressive apps:
→ DEXs with CEX-like UX, accessing the liquidity of all chains
→ Verifiable AI interactions with onchain results
→ ZK-wrappers for centralized IDs
We're thrilled to announce a collaboration with @celestiaorg to build Blobstream Zero, a new-generation zkVM-based Blobstream bridge. 🟡
Blobstream Zero will bridge Celestia's permissionless DA layer to Ethereum, Optimism, Bitcoin, Solana, and more...
2/ Blobstream Zero opens up a new class of modular apps: ZK Coprocessors.
Dapps on Ethereum, Optimism, and Solana can run highly functional and data-rich ZK programs, powered by RISC Zero and Celestia, while maintaining composability.
3/ As a fully open-sourced and permissionless public good, any developer and project can run Blobstream Zero and generate ZK proofs locally.
The Rust-based repo will be easily upgradable and extensible, allowing projects to modify the bridge to fit their needs. ⏫
✅ Solidity smart contract execution
