The L1 Weekly Report is published every Friday, focusing on the development of Layer 1 blockchains. If you have any suggestions, feel free to contact [email protected].

Bitcoin

• CHECKSIGFROMSTACK(VERIFY/ADD)
  • Discussions are ongoing about integrating CHECKSIGFROMSTACK (CSFS) BIP into Bitcoin, with questions about including CSFSVerify (CSFSV) and CSFSAdd.
  • There is debate over whether to add CSFSV to pre-tapscript due to its compatibility with NOP forking and potential use cases.
  • Opinions vary on the necessity and benefits of adding CSFSV and CSFSAdd, with some developers favoring a more focused set of changes.
• ColliderScript: Covenants in Bitcoin via 160-bit hash collisions
  • A new method for creating and spending covenants on Bitcoin using Tapscript has been published, which does not require soft forks.
  • Creating covenants is easy, but spending them requires significant computation and large Bitcoin transactions.
  • The approach enables arbitrary computation on Bitcoin transaction data, limited only by the circuit size that can fit into a 4MB transaction.

Ethereum

• QUIC Support Among Ethereum Consensus Layer Clients
  • Approximately 42% of Ethereum Consensus Layer nodes support QUIC, primarily due to Lighthouse’s default enablement.
  • QUIC adoption is growing, but mainly over IPv4 with minimal support over IPv6.
  • Future QUIC support is expected to expand to other clients as the specification matures.
• Concerning Ethereum’s Fee Issues
  • Ethereum transaction fees are relatively low, but smart contract calls are costly.
  • A minimalist smart contract for swapping tokens is proposed to reduce fees.
  • Concerns include potential arbitrage vulnerabilities and reliance on oracles for price data.

Aptos

• Multisig Platform On Aptos
  • The multisig platform, built natively for the Aptos ecosystem

Sui

• Sui Foundation Partners With Babylon Labs, Lombard And Cubist For Programmable Bitcoin
  • $BTC holders will soon be able to stake Bitcoin through Babylon’s staking protocol
  • The teams are building a future where $BTC holders can participate in on-chain finance without compromising security or liquidity: Lombard co-founder
  • Users from all blockchain ecosystems can now come to Sui to participate in an environment where $BTC plays a role: Cubist head of Ecosystem Development
  • NAVI has signaled interest in working with Babylon to support $LBTC pools on the protocol

Ton

• MyTonWallet v3.1: Connected Dapps Access, Auto-Lock, Ledger for Mobile, and More
  • MyTonWallet v3.1 introduces quick access to connected dapps, improved security settings, and Ledger support for mobile devices.
  • The update includes smarter address search, anti-poisoning scam protection, and gasless transactions.
  • MyTonWallet now offers optimized token purchases via MoonPay and Tonscan explorer integration.
