Chorus One: Solana’s new consensus mechanism Alpenglow’s economic incentives and tradeoffs compared to the existing PoH

PoS Blockchain Validator Operator Chorus One Published an Analysis of Solana's New Consensus Mechanism Alpenglow, Comparing Economic Incentives and Trade-offs with Existing PoH. Alpenglow Increases Byzantine Fault Tolerance from 33% to 40%, but Requires Lower Network Latency (150ms vs 400ms), Reducing MEV Profits by Approximately 38% for Arbitrage and 24% for Sandwich Attacks, Potentially Driving Geographical Centralization of Validators. Sharded Propagation Design Prioritizes High-Stake Validators, Potentially Imposing a Delay Tax on Smaller Validators, Affecting Decentralization. Removing PoH May Increase the Burden of Processing Invalid Transactions. Reward Mechanisms Are Vulnerable to Manipulation, Such as Self-Reporting and Voting Delays, with Randomness Leading to Volatile Earnings for Low-Stake Validators. Alpenglow Needs to Optimize Parameters to Balance Security, Efficiency, and Fairness.
