Odaily News: The public chain Solana will launch the Alpenglow upgrade on its mainnet at approximately 15:00 (UTC) on October 21, completely replacing its validator consensus system. The upgrade will phase out TowerBFT, with the goal of reducing transaction finality from the current approximately 12.8 seconds to about 150 milliseconds.

Alpenglow adopts Votor, which moves vote transactions out of blocks, allowing validators to communicate directly and generate certificates; final confirmation can be achieved in the first round with 80% or more stake support, while support rates between 60% and 80% will enter a second round of voting.

After the upgrade, vote transactions will no longer be counted in blocks, and Solana's public transaction count and TPS will drop significantly, but actual activity will not decrease as a result. Ordinary users do not need to take any action, and the Solana Virtual Machine, transaction format, programs, and fees will all remain unchanged.

The feature switch will be activated at epoch 1064, and TowerBFT will continue to run for approximately 5,000 slots, or about 18 minutes, after which Alpenglow will take over. Each vote account will need to pay an additional validator admission fee of 0.8 SOL, which will be burned; the launch date of the Rotor upgrade has not yet been announced. (Decrypt)

Odaily News: The U.S. Office of the Comptroller of the Currency (OCC) has released a report on "debanking," stating that some banks have used public and non-public policies to restrict financial services for multiple industries, including crude oil, natural gas, tobacco, firearms, and digital assets. The report notes that some institutions restricted digital asset businesses, including issuers, exchanges, and managers, often citing financial crime concerns as the reason.

The OCC stated that the report was prepared in accordance with an executive order signed by Donald Trump in August 2025, which aims to prevent what it calls "illegal debanking." The report reviewed 9 major banks but did not list specific cases related to digital asset businesses, nor did it comprehensively quantify the scope of debanking or related allegations.

OCC head Jonathan Gould said that some debanking decisions related to coal and firearms were not based on financial risk, with banks citing reputational risks from negative news, public protests, and support for related industries. In November 2024, more than 30 tech and crypto industry executives said they were unable to access banking services. (Cointelegraph)

The report calls on the U.S. Congress to take measures to prevent financial institutions from denying banking services based on political factors.

Odaily News: Cryptocurrency exchange Coinbase stated that the Bitcoin it custodies accounts for approximately 5% of the total existing Bitcoin supply, and urged Bitcoin developers to immediately begin addressing the quantum computing threat. Coinbase pointed out that Bitcoin consensus changes and ecosystem migration could take years, and action cannot wait until quantum computers with the capability to break signature schemes emerge.

Coinbase recommends adopting a flexible "container" design similar to BIP-360 to enable the gradual replacement of quantum-resistant signature systems; it also proposed a phased "1-of-2" approach that would allow the same funds to be spent via either traditional keys or quantum-resistant keys during the transition period. The proposal would also need to be compatible with multi-party computation (MPC) key-splitting mechanisms.

Coinbase stated that dormant, lost, and Satoshi-era Bitcoin holdings constitute a separate governance issue, and that any rescue mechanism itself must also be quantum-resistant. In January of this year, Coinbase established a Quantum Advisory Board; in July, it joined the Bitcoin Security Alliance alongside BlackRock and Strategy, with a combined commitment of $15 million for Bitcoin's quantum-resistant overhaul.
