Bitcoin

Bitcoin’s developers just admitted something in writing: secrecy doesn’t protect you when a machine can rediscover the secret.

1. 1
   AI crypto threat debate

   Experts are sharply divided over how urgently AI and quantum advances threaten existing blockchain wallet cryptography.

   Latest: HAWK is withdrawn from NIST’s signature round after an AI-discovered key-recovery attack, and Germany’s BSI advises against Classic McEliece — two post-quantum candidates felled by mathematics, no quantum computer involved.

   Strategy BTC treasury stress

   Strategy is navigating a crisis in its Bitcoin treasury model, oscillating between forced BTC sales, purchase pauses, and resumed accumulation as STRC preferred stock stress and unrealized losses reshape its capital framework.

   Latest: Sept 8 par-test verdict by 8-K: no BTC bought/sold; $176M STRC repurchased, buyback DOUBLED to $2B; reserves −$176M to ~$6.5B; 845,050 BTC unchanged — the war chest chose the preferred

   Bitcoin slides toward $60K as crypto-treasury model cracks and macro headwinds mount

   Latest: The minority chain stays frozen at two blocks a day after splitting — ~0.15% of hashrate enforces it (most signallers included didn't), with a first difficulty adjustment decades away at current pace

   BlackRock crypto expansion

   BlackRock is steadily expanding its crypto product suite — from Bitcoin ETFs and covered-call funds to Aladdin integrations and global launches — cementing its dominance in institutional digital assets.

   Latest: BlackRock Canada launches IBQT on the TSX — a 97/3 equities-bitcoin portfolio built as a fund-of-funds, with the bitcoin sleeve routed through its own Canadian bitcoin ETF — as the firm says bitcoin's equity correlation is weakening

   BIP-110 Bitcoin fork battle

   Bitcoin's BIP-110 soft fork is collapsing under near-zero miner support, fierce community opposition, and chain-split risk as its mandatory-signaling phase opens.

   Latest: Days before BIP-110's mandatory-signaling window opens (~Aug 9), a developer rebases Dashjr's 2017 proof-of-work-change code onto Knots as a "last resort" against miner resistance — while Foundry puts signalling to a customer vote

   Bitcoin quantum threat response

   Growing quantum computing capabilities are forcing Bitcoin and the broader crypto industry to urgently plan and implement post-quantum cryptographic defenses.

   Latest: IBM and Algorithmiq claim their strongest quantum advantage to date — a materials-simulation milestone with a new trust framework, and no direct bearing on Bitcoin's cryptography
