The post Vitalik Buterin’s Latest Proposal – Transaction Gas Cap appeared on BitcoinEthereumNews.com.

Welcome to The Protocol, CoinDesk’s weekly wrap-up of the most important stories in cryptocurrency tech development. I’m Margaux Nijkerk, CoinDesk’s Tech & Protocols reporter. In this issue: Vitalik Buterin’s New Proposal Seeks 16.7M Gas Cap on Ethereum to Rein In Transaction Bloat Jack Dorsey Unveils Bitchat: Offline, Encrypted Messaging Inspired by Bitcoin Volkswagen ADMT Taps Solana-Based Hivemapper Bee Maps for Driverless Data Eigen Labs Axes 25% of Staff to Focus on Building EigenCloud Network News NEW ETHEREUM PROPOSAL FROM VITALIK BUTERIN: A new Ethereum proposal, co-authored by Vitalik Buterin and Toni Wahrstaetter, aims to impose a hard cap on the maximum gas a transaction can consume in a move developers say could strengthen network stability and make the chain more viable for certain applications. The proposal, EIP-7983, suggests limiting individual transactions to 16,777,216 gas (2²⁴) — a sharp change from the current design, which technically allows a single transaction to consume the gas allocation of an entire block. As a design choice, that introduces several performance and security challenges. When a single transaction consumes nearly all the available gas, it disrupts the distribution of workloads across the network and tends to make block execution less efficient. So the proposed cap is expected to simplify engineering challenges and aligns with Ethereum’s shift toward modularity, though it may require splitting large transactions. — Shaurya Malwa Read more. JACK DORSEY UNVEILS BITCHAT WHITEPAPER: Jack Dorsey, founder of Twitter (now X) and fintech company Block (SQ), published a whitepaper for Bitchat, a decentralized messaging protocol that enables fully encrypted communication without the internet. Bitchat would operate over Bluetooth Low Energy (BLE), allowing nearby devices to form a mesh network that relays messages hop-by-hop, according to the whitepaper. When a message is sent, it would travel across nearby devices acting as temporary nodes until it…
