🚀 Arbitrum Proposes New Transaction Ordering Strategy Timeboost

According to Odaily, Arbitrum has initiated a vote on implementing a new transaction ordering strategy called Timeboost for Arbitrum One and Nova. This strategy aims to provide traders with a fast track to gain transaction priority through an auction system, thereby capturing arbitrage and frontrunning opportunities. Timeboost is designed to mitigate the negative impacts of MEV (Miner Extractable Value) searcher competition while returning the benefits of the transaction ordering market to ArbitrumDAO. Traders can choose to bid using either ETH or ARB tokens.
The proposal outlines two primary methods for handling the generated revenue: transferring ETH income to the DAO treasury or burning the ARB income. If the proposal is approved, a public testnet will be conducted. Currently, 57.7% of voters support transferring the collected ETH to the DAO treasury.#Arbitrum #Timeboost #TransactionOrdering #MEV #Arbitrage #Frontrunning #DAO #ETH #ARB #Crypto #Blockchain
🚀 Solana Foundation Updates Validator Delegation Program Standards

The Solana Foundation has announced updates to its validator delegation program, set to be implemented on May 1. According to NS3.AI, these changes aim to enhance the fairness of transaction ordering, address issues related to censorship, optimize block production timing, and manage validator concentration across Autonomous System Numbers (ASNs) and data centers. The foundation's initiative seeks to improve the overall efficiency and decentralization of the Solana network.#Solana #Blockchain #Validator #Delegation #Decentralization #Crypto #NetworkSecurity #TransactionOrdering #CensorshipResistance #BlockProduction #SOL
🚀 Challenges and Prospects of Encrypted Mempools in Ethereum

Jonathan Passerat-Palmbach, a senior research scientist at Flashbots and visiting scholar at Imperial College, discussed the academic evolution and practical limitations of encrypted mempools at the EthCC[9] conference. According to Foresight News, he highlighted the progression from early committee-based threshold encryption schemes to batched threshold encryption and the Beast-Mev scheme, which combines silent settings with batch decryption. Despite these developments, no current solution meets all the protocol-level requirements such as silent settings, non-interactive decryption, small keys, and small ciphertexts, preventing the cryptographic aspects of encrypted mempools from being directly integrated into the Ethereum protocol.
The economic implications pose a more significant challenge. The blind ordering mechanism used in encrypted mempools, where transactions are ordered while encrypted, leads to three main issues: searchers submitting numerous blind arbitrage bundles, resulting in on-chain spam; reduced MEV subsidies making geographically remote validators less competitive, thus increasing centralization; and a decline in user execution quality, with significant transaction price deviations and higher rollback probabilities. Jonathan noted that the timing design of decrypting after execution hinders the effective operation of auction mechanisms, which are optimal for handling MEV incentives. He suggested programmable privacy as an alternative, allowing a balance between full encryption and full transparency, currently achievable through TEE and potentially through more advanced solutions like FHE in the future. He concluded that privacy should not exist independently of economic incentives and should continue to be experimented with outside the protocol rather than being hastily integrated.#Ethereum #EncryptedMempools #MEV #BlockchainPrivacy #ThresholdEncryption #Flashbots #CryptoEconomics #Decentralization #ProgrammablePrivacy #FHE #TEE #Cryptography #TransactionOrdering #EthCC #ETH
