WuBlockchain’s August technology report tracked a broad set of blockchain infrastructure updates across Bitcoin, Ethereum, Solana, major Layer 2 networks, and several other ecosystems. The report said Bitcoin’s long-debated BIP-110 entered real activation in August but failed to gain support, with miner signaling at only about 2.5% during the mandatory signaling phase. Nodes enforcing the rule began rejecting non-signaling blocks from height 961,632, effectively creating a minority chain that produced only around two blocks before largely stalling, while the main Bitcoin network continued as normal. On Ethereum, the Glamsterdam upgrade moved from internal DevNet testing into a public test phase, with DevNet 8/Platåberget launched on Aug. 13 and the Gloas fork activated on Aug. 20. Testing has shifted from basic functionality to edge cases and client compatibility, while tentative testnet activation targets of Sept. 28 for Sepolia and Oct. 26 for Hoodi have been proposed. Hegotá also advanced from open proposal intake into a narrower candidate-selection stage. The report also highlighted rising performance competition across scaling networks. OP Mainnet upgraded from 250ms Flashblocks to 200ms Subblocks, Base outlined a 200ms Native Blocks plan, and Solana is preparing to reduce mainnet slot time to 350ms starting from epoch 1020. In parallel, Arbitrum said real mainnet blocks can now be proven with SP1-generated ZK proofs, extending its path toward a multi-proving architecture.

Arbitrum’s development team said it is introducing zero-knowledge, or ZK, proofs to the Arbitrum platform as part of a multi-proof settlement model. According to the team, the change could reduce the time needed to settle Arbitrum blocks to Ethereum Layer 1 from several days to several hours. The stated goal is to improve capital efficiency for users, bridges and protocols while keeping the network’s security model intact through multiple forms of proof. The capability is intended for both Arbitrum One and app-specific chains built on the Arbitrum platform. Offchain said it plans to submit an upgrade proposal to the DAO at a later stage. The team also outlined several milestones already reached, including generating ZK proofs for real mainnet blocks in the SP1 zkVM and proving Stylus WASM contracts alongside Solidity contracts. It added that the BoLD settlement protocol can already accept ZK proofs with backing from a fast confirmation committee, while the existing dispute game remains in place as a fallback path. Arbitrum said it is still working to reduce proving costs, fold the code into Nitro’s main production path, and later connect ZK settlement to node configuration so chains can enable it as needed.

Arbitrum’s 2025 Transparency Report shows over 2.1 billion transactions, about $20 billion in TVL, nearly $10 billion in stablecoins, and rising RWA and tokenized ETF activity.
