Solana deploys Alpenglow consensus upgrade to testnet ahead of mainnet launch

Solana has pushed its Alpenglow consensus overhaul onto testnet, a step toward cutting block finality by roughly 99% just as SOL trades near its strongest level since January. The upgrade’s public testing phase lands alongside a surge in tokenized real-world assets and trading volumes that now rival the New York Stock Exchange.

• Alpenglow’s Votor phase targets block finality of about 150 milliseconds, down from roughly 12.8 seconds under TowerBFT.
• Real-world assets on Solana reached about $4.6 billion in early September, up from the $4 billion first crossed in August.
• Solana DEXs logged about 208 million trades the week ending September 13, edging past the New York Stock Exchange’s roughly 190 million.

• 150ms Alpenglow’s target finality versus 12.8 seconds under TowerBFT
• $4.6B Solana real-world-asset value versus $4B milestone in August
• 208M weekly Solana DEX trades versus roughly 190M on the NYSE

Solana developer Anza confirmed this week that Alpenglow has begun deploying on testnet ahead of devnet and mainnet-beta releases. The move targets block finality of about 150 milliseconds, a steep drop from the 12.8 seconds validators need today. The timing coincides with SOL trading around $117 after touching almost $120 this week, its strongest level since late January.

Votor Cuts Solana’s Finality Wait by 99%

Alpenglow’s first phase, Votor, replaces the onchain vote transactions validators currently submit with votes sent directly between validators. Those votes combine into certificates capable of finalizing a block within one or two voting rounds, cutting the wait for an irreversible transaction by roughly 99% against the current baseline.

The upgrade leaves the Solana Virtual Machine, transactions, programs and fees untouched. Only the consensus layer changes.

The rollout follows months of preparation among validators and infrastructure providers, many of which had to adjust systems that stream blocks, track votes or depend on Solana’s existing commitment structure. A second component, Rotor, will later replace Turbine, the network’s block-data distribution system, though Solana has scheduled that separately according to the Alpenglow upgrade page, keeping Votor the immediate focus of testnet.

The consensus rework follows other throughput upgrades. Solana activated Transaction V1 this month, raising maximum transaction size to 4,096 bytes from 1,232, while its slot-time roadmap continues trimming target block times from 400 milliseconds toward 200 milliseconds.

SOL Nears $120 as Nasdaq Gap Narrows to 47 Million Trades

SOL has gained roughly 25% over the past month, CryptoSlate’s data shows, pushing the token back toward the roughly $120 level it last touched in late January. Network activity has expanded alongside the price move.

Real-world assets on Solana reached about $4.6 billion in early September, extending a climb that pushed the sector past $4 billion for the first time in August. Trading has kept pace: Solana decentralized exchanges recorded about 208 million spot trades in the week ending September 13, according to data cited by the Kobeissi Letter, narrowly topping the roughly 190 million trades executed on the New York Stock Exchange over the same span and narrowing the gap with Nasdaq to about 47 million trades. Jupiter, Solana’s largest aggregator, accounted for more than 80 million trades during September, up 38% from the prior month.

Multicoin’s Samani Bets SOL Overtakes Ether This Cycle

Multicoin Capital co-founder Kyle Samani has said he expects SOL’s market capitalization to surpass Ethereum’s before the current cycle ends, pointing to developers migrating toward Solana and its recent lead over Ethereum in network fees. The gap remains wide: Samani’s own comparison put Solana’s market cap near $58 billion against roughly $293
