Cc9f267dcClaimSolana core engineering firm Anza developed the Alpenglow upgrade and took the protocol from a white paper to mainnet deployment in under 18 monthsAgreeDisagree
Cc9f267dcClaimAlpenglow is designed to continue operating with up to 20% of stake acting maliciously and another 20% offlineAgreeDisagree
Cc9f267dcClaimAlpenglow condenses Solana's previous two-step transaction confirmation process under TowerBFT into a single step for finalityAgreeDisagree
Cc9f267dcClaimMoving validator votes off-chain under Alpenglow is expected to reduce Solana's reported transaction counts and TPS because vote transactions are no longer included in blocksAgreeDisagree
Cc9f267dcClaimSolana activated its Alpenglow consensus upgrade on mainnet-beta on October 21, 2026, replacing TowerBFT at slot 459,653,000AgreeDisagree
Cc9f267dcClaimThe Alpenglow upgrade reduces Solana's transaction finality from about 12.8 seconds to roughly 150 millisecondsAgreeDisagree
Cc9f267dcClaimAnza is researching a post-quantum upgrade named Quantumglow to introduce hash-based signatures while preserving 150-millisecond finalityAgreeDisagree
Cc9f267dcClaimDuring public testnet and devnet testing, Alpenglow achieved median finality times as low as 54 millisecondsAgreeDisagree
Cc9f267dcClaimAlpenglow on Solana can finalize a block in one round if 80% of stake votes for it, or in two rounds requiring 60% of stake per roundAgreeDisagree
Cc9f267dcClaimUnder Solana's Alpenglow upgrade, validators pay a flat 0.8 SOL per epoch fee rather than paying per-vote transaction feesAgreeDisagree
Cc9f267dcClaimECDSA authenticates blockchain account ownership by generating digital signatures on transactions across a distributed ledgerAgreeDisagree
Cc9f267dcClaimAn amendment to XRP Ledger rules, such as fixCleanup3_4_0, requires continuous approval from over 80% of the network's 35 default trusted validators—at least 29 votes—for two consecutive weeks before activatingAgreeDisagree
Cc9f267dcClaimThe fixCleanup3_4_0 package updates vault asset rounding calculations, loan default criteria, and cryptographic signature role prefixes to prevent signature reuse across different roles.AgreeDisagree
Cc9f267dcClaimThe XRP Ledger fixCleanup3_4_0 amendment reached 29 validator votes on October 9, 2026, and held 29 on October 19, 2026, tracking activation around 09:34 UTC on October 23, 2026, with a single validator withdrawal restarting its 14-day countdown.AgreeDisagree

Cc9f267dcClaimThe XRP Ledger evaluates amendment activation decisions at designated intervals called flag ledgers, occurring every 256 ledgers.AgreeDisagree
Cc9f267dcClaimUnder Solana's Alpenglow Votor system, Solana validators communicate directly off-chain to aggregate votes into cryptographic certificates rather than recording each vote as an onchain transactionAgreeDisagree
