StarkWare has introduced S-two, a circuit-based recursion system that significantly improves Starknet's proving capabilities.​

Key improvements:

  • Latency reduced from ~1 minute to ~3 seconds (20x faster)
  • Proving now possible on standard laptops
  • Smaller and more cost-effective proofs

This advancement enables decentralized proving by lowering hardware requirements, allowing more participants to run provers from consumer devices.​ The optimization also enhances privacy features on Starknet by making zero-knowledge proofs more accessible and efficient.​

The S-two prover represents a practical step toward making ZK technology more scalable and accessible for everyday use.​

**BTC-backed lending sees significant growth on Vesu** The number of loans backed by Bitcoin and Bitcoin Liquid Staking Tokens (LSTs) has increased 6x on the Vesu platform. **Key metrics:** - BTC collateral grew from 35 to over 260 tokens (7x increase) - Supported assets include wBTC, LBTC, tBTC, solvBTC, and their Endur LST variants Users can now leverage multiple forms of wrapped Bitcoin and liquid staking derivatives as collateral for borrowing on the platform.

Starknet Achieves Full Post-Quantum Security with Wallet Integration

**Starknet has completed its transition to post-quantum security**, marking a significant milestone in blockchain infrastructure. **Key achievements:** - Post-quantum proving system (already implemented by design) - Post-quantum wallets now live on mainnet - Native Account Abstraction enables seamless migration - No address changes or hard forks required The network's proving system was built with post-quantum resistance from the start. The recent wallet integration provides users with a clear upgrade path to quantum-resistant security without disrupting existing operations.

鈿狅笍 Haiko Users: Urgent Withdrawal Reminder

**Urgent Action Required for Haiko Users** Users with funds on Haiko are being reminded to **withdraw their assets immediately**. This follows a pattern of platform transitions in the ecosystem. **Key Points:** - Withdraw all remaining funds from Haiko as soon as possible - No specific deadline mentioned, but urgency is emphasized - Similar to previous situations like Rhino's legacy StarkEx system withdrawal period **What to Do:** Check your Haiko account and initiate withdrawals if you have any remaining balance.
