Solana Proposes Alpenglow: A Major Consensus Overhaul to Replace PoH and Tower BFT

Solana is set to revolutionize its consensus mechanism with the introduction of Alpenglow, a groundbreaking proposal designed to replace both proof-of-history (PoH) and Tower BFT. This strategic move aims to address the network’s architectural limitations, which have hindered optimization despite its renowned speed and throughput. As of May 27, 2025, the SOL price stands at 172.29 USDT, reflecting the market’s anticipation of this transformative upgrade.

Solana Proposes Alpenglow to Replace Proof-of-History and Tower BFT

Solana is set to overhaul its consensus mechanism with the introduction of Alpenglow, a new proposal aimed at replacing both proof-of-history (PoH) and Tower BFT. The MOVE addresses long-standing limitations in the network’s architecture, which, despite enabling high speed and throughput, has struggled with complexity and optimization challenges.

Proof-of-history, Solana’s cryptographic clock, provided a unique way to order events but never resolved consensus itself. Paired with Tower BFT, the mechanism worked but became increasingly cumbersome as the network’s ambitions grew. Alpenglow represents a structural reimagining of Solana’s consensus layer, promising to streamline operations and enhance scalability.

Mango Markets Attacker Has Conviction Overturned—Why?

A federal judge overturned the conviction of Avraham Eisenberg, the crypto trader accused of orchestrating a $110 million exploit against Solana-based decentralized exchange Mango Markets in 2022. The ruling vacates charges of commodities fraud, manipulation, and wire fraud—a surprising twist in a case that had been seen as a litmus test for DeFi accountability.

Eisenberg’s strategy involved artificially inflating the value of collateral on Mango Markets’ DEX, then borrowing against the manipulated positions. While the jury initially found him guilty last year, the court’s reversal highlights lingering ambiguities in applying traditional financial laws to decentralized protocols.

The solana ecosystem, which had been rattled by the original incident, shows no immediate price reaction to the legal development. Market observers note the ruling may embolden DeFi participants but could delay regulatory clarity for the sector.
