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 pgnodexyz@gmail.com.

Bitcoin

• What is time-warp-attack and how does it work in general
  • The article discusses the concept of a "time warp attack," a consensus vulnerability in the Bitcoin protocol that involves manipulating block timestamps to artificially adjust mining difficulty. It details how attackers could exploit the difficulty adjustment mechanism by strategically setting timestamps, allowing them to mine more blocks and earn greater rewards. The piece suggests implementing additional checks on timestamps within difficulty adjustment periods to mitigate such attacks.

Ethereum

• Possible futures of the Ethereum protocol, part 1: The Merge
  • This article discusses potential enhancements to Ethereum's proof-of-stake system, focusing on technical improvements like single-slot finality and staking democratization. It also explores solutions for faster transaction confirmations and the implementation of single secret leader election to enhance security. Additionally, the piece touches on broader research areas, including quantum resistance and 51% attack recovery strategies.
• Possible futures for the Ethereum protocol, part 2: The Surge
  • This article discusses Ethereum's scaling strategy through sharding and layer 2 protocols, aiming to achieve over 100,000 TPS while preserving the decentralization and robustness of the Ethereum network. It addresses challenges such as data availability sampling, cross-layer interoperability, and the maturity of L2 proof systems. The ultimate goal is a unified Ethereum ecosystem with seamless interaction between different layers and protocols.

Sui

• Sui's mainnet has been upgraded to V1.35.2
  • Additionally, the Sui protocol has been upgraded to version 64, with other key upgrades including: enabling distributed voting scoring on the testnet, reducing the minimum stake for the random beacon protocol to 700 to lower the cost of running the protocol, adding support for filtering transactions by affected accounts, and Move lint now warns against unnecessary self-assignment, among others.

Aptos

• Ecosystem spotlight jellybean tm bridging physical and digital realms
  • Jellybean™ is an innovative project on the Aptos blockchain that integrates NFC technology to bridge physical toys with the digital world, creating interactive, blockchain-powered experiences. It leverages Aptos' scalable infrastructure to offer a secure platform that enhances user engagement through on-chain rewards and real-time notifications, without the need for app downloads or incurring app store fees. Jellybean™ has demonstrated significant success with an impressive 50% engagement rate and 44% retention on Day 5 of their Aptos Experience campaign, showcasing the potential for physical-digital integration in Web3 loyalty and engagement systems.

Ton

• TON Is Integrating Axelar for Open Interoperability Across Web3
  • TON is integrating Axelar's Mobius Development Stack (MDS) to enhance its interoperability layer, leveraging Axelar's Interchain Amplifier technology to improve scalability and drive mass adoption opportunities. This integration will allow TON to securely connect with various blockchain ecosystems, including Cosmos, Ethereum, and Polkadot, and is expected to include other popular consensus approaches later this year. The collaboration aims to provide a unified cross-chain connection, benefiting both users and developers by preventing fragmented liquidity and enhancing the overall Web3 experience within the TON ecosystem.
• Exploring TON Memelandia: A New World for Memecoins to Reign
  • TON Memelandia is a decentralized initiative on the TON blockchain aimed at fostering the growth of memecoins by providing a creative space for their communities. It offers a range of activities, including trading battles, airdrops, and marketing support, to engage and incentivize participation in the memecoin economy. The project is backed by the TON Foundation and TON Society, with the goal of making TON a leading hub for memecoins within the broader digital culture and decentralized finance.
