Even if Bitcoin eventually adopts post-quantum protections for on-chain outputs, five parts of the Lightning Network’s off-chain payment system would still need separate upgrades, according to a Sept. 12 research preprint. The paper proposes PQLN, a hybrid post-quantum extension implemented as a rust-lightning research prototype. It targets gossip, which distributes node and channel information; encrypted
Crypto analyst Ali Martinez shared some notable technical levels following the recent strong price increases in Bitcoin ($BTC) and $XRP.

Bitcoin’s rally and the Federal Reserve’s new financial-risk gauge describe two different time horizons. $BTC reflects demand and positioning in today’s market.

In Figure 2, the final financial-leverage

Grayscale changed MNRS into GCPU and renamed the fund the Grayscale AI Compute ETF on September 22. The ETF now tracks the Indxx High Performance Computing Index and charges a 0.59% expense ratio. Despite the new mandate, major holdings such as IREN, Hut 8 and Applied Digital keep the portfolio closely connected to companies that
In brief Coinbase is developing post-quantum custody safeguards to support a wide range of signature schemes, according to Head of Cryptography Yehuda Lindell. Traditional Multi-Party Computation (MPC) relies on split keys, but many post-quantum signature schemes may be “non-MPC-friendly.” Coinbase is exploring a fallback architecture that combines post-quantum threshold decryption with programmable Hardware Security Modules
Bitcoin has held above $85,000 after gaining 12.3% over the past seven days, with improving spot demand and ETF inflows supporting the recovery.
