Blockstream: Bitcoin Can Add New Signature Schemes to Counter Quantum Threats

Grade Abullish AI signal$BTC

Blockstream says Bitcoin could adopt new signature schemes to defend against future quantum computing threats, with its researchers favoring Falcon-1024 among the lattice-based alternatives evaluated. The team identified deployment challenges including unfinished standardization, hardware wallet memory requirements and the lack of a workable public-key derivation scheme, while hash-based signatures remain the more conservative near-term option. Potential quantum-resistant upgrades could strengthen Bitcoin's long-term security, although significant technical hurdles remain before deployment.

Bitcoin Slips Toward 50-Week Moving Average, Putting Post-September Recovery To The Test: Weekly Close Streak Hangs In Balance

Bitcoin is testing its 50-week moving average near $75,580 as its hard-won recovery above the key long-term trend line faces its biggest challenge since September. BTC has maintained seven consecutive weekly closes above the average, but its price cushion has narrowed to less than 1% after a 5.5% decline from around $80,100. The 50-week moving average previously acted as resistance during bear markets, while Bitcoin briefly fell below it to $74,720 before recovering above the level. The next critical test is the November 8 weekly close, which would extend the streak to eight weeks if BTC holds above the average. A weekly close below $75,580 could undermine the September recovery and revive fears of a false breakout, potentially increasing bearish pressure on Bitcoin.

Quantum Computers Are Poised to Crack Encryption. AI Could Beat Them to It. — WSJ

AI-driven mathematical breakthroughs are raising concerns that artificial intelligence could weaken the encryption protecting global digital systems, potentially challenging assumptions underpinning modern cryptography. Recent AI research has reportedly disproved the Exponential Time Hypothesis, while Ethereum creator Vitalik Buterin is urging the development of post-AI cryptography to address emerging risks. The implications remain uncertain, but further AI advances could pressure existing encryption standards and accelerate demand for stronger cryptographic security across financial and cryptocurrency networks.

Russia finalizes crypto trading rules ahead of Nov. 17 rollout

Russia's central bank has finalized regulations allowing retail investors to trade Bitcoin, Ethereum and Tether through authorized intermediaries starting November 17, establishing a new regulated pathway into crypto markets. Non-qualified investors face an annual purchase limit of 300,000 rubles per intermediary, while qualified investors have no purchase limits; all participants must pass mandatory testing. The regulatory rollout could expand institutional and retail access to crypto in Russia, although restrictions on peer-to-peer trading and self-custody transfers could limit broader adoption.

What If the Only Companies That Let Their Stocks Be Tokenized Are Crypto Firms? — Barrons.com

OKX and Intercontinental Exchange's planned tokenized stock venue faces a major roadblock, with nearly all companies approached outside the crypto industry objecting to having their shares listed. Of the original 62 companies, only six crypto-linked firms have not objected, while 11 additional objections have been received; Securitize says it plans to make its shares available on the platform. Issuer resistance could slow retail adoption of tokenized stocks and create an advantage for crypto-native companies willing to embrace blockchain-based securities trading.
