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

• Bitcoin Core 28.1 Release Candidate 1 Available
  • Release candidates are test versions for releases.When no critical problems are found, this release candidate will be tagged as v28.1
• The Quantum Threat to Bitcoin: Implications for Miners, Nodes, and Wallets
  • Bitcoin may need to transition to quantum-resistant algorithms
  • The practicality of quantum computers breaking Bitcoin is still far off.
• Transaction-Relay Throughput Overflow Attacks against Off-Chain Protocols
  • A new transaction-relay jamming attack targets Bitcoin’s time-sensitive protocols by exploiting transaction selection and propagation mechanisms
  • The attack has two variants: “high overflow” and “low overflow,” both of which could affect Lightning Network channels
  • Further investigation and practical testing of this attack are necessary to understand its implications and develop mitigations

Ethereum

• On Increasing the Block Gas Limit: Technical Considerations & Path Forward
  • Increasing Ethereum’s block gas limit beyond 36 million requires careful consideration due to client constraints and potential network instability
  • The Pectra network upgrade aims to reduce block sizes and provide data needed for safe increases in capacity
  • Core developers advocate for a measured approach to scaling, prioritizing network health and security over rapid increases in the gas limit
• Overpass Channels: Horizontally Scalable, Privacy-Enhanced, with Independent Verification, Fluid Liquidity, and Robust Censorship Resistance
  • Overpass Channels is a decentralized payment network using zero-knowledge proofs for scalability and privacy
  • It eliminates the need for mining and traditional consensus mechanisms, focusing on direct verification between parties
  • The network aims to address transaction costs, scalability, and privacy concerns in blockchain payments
• Bringing privacy to EVM applications using confidential computing via co-processors
  • The post discusses integrating privacy into EVM applications using confidential computing and co-processors
  • It proposes encrypted ERC20 tokens and differential privacy techniques to protect user transaction data
  • The goal is to balance transparency, privacy, and regulatory requirements in blockchain and DeFi ecosystems.

Solana

• Electric Capital’s Developer Report shows Solana as the #1 ecosystem for new developers in 2024
  • Led by developer growth in Asia
  • Developers are predominantly active in the DeFi and NFT sectors

Aptos

• Support for native USDT on Aptos is live on Binance

Sui

• Sui’s Total Value Locked (TVL) has surpassed $1.75B
  • That’s more than 1,000% growth over the last year
