Banco de Portugal and Banco de Espanha have signed a memorandum to jointly develop a Post-Quantum Cryptography Cooperation Program, warning that an uncoordinated migration to quantum-resistant systems could create systemic risk.
A proposal coordinated by Ben Edgington would change how Ethereum validators vote, shortening the time needed to confirm transactions as final from roughly 16 minutes to about four.
Solana's mainnet has moved to Alpenglow, a new consensus mechanism promising transaction finality in roughly 150 milliseconds and validator cost cuts of around 60%, after a bumpy testnet run.
Solana's Alpenglow consensus overhaul, due on mainnet October 21, 2026, cuts transaction finality from 12.8 seconds to roughly 150 milliseconds — but client incompatibility and new validator compliance rules raise operational risks ahead of the switch.
A non-binding governance vote on becoming an independent, quantum-resistant layer-1 is passing with near-unanimous support from STRK holders, though the proposal remains at an early, exploratory stage.
Solana Mobile has named Ledger its first hardware expansion partner, integrating its Seeker wallet and dApp store into the newly unveiled Ledger Atom device, announced days after Ledger disclosed a supply-chain attack on its products.
Reports of tampered Ledger devices sold through reseller CryptoBilis have prompted divergent responses from OneKey, Trezor and Tangem, while separate incidents suggest the problem extends beyond a single sales channel.
Charles Guillemet dismissed warnings of an imminent AI-driven break of ECDSA signatures, arguing that recent mathematical advances remain theoretical and that a real collapse of asymmetric cryptography would take down far more than crypto wallets.
The French hardware wallet maker unveiled Crypto Loan at TOKEN2049 in Singapore, letting holders borrow USDC or USDT against wrapped bitcoin collateral while keeping custody on their device.
Core Lightning has told operators to update to version 26.06.8 immediately after confirming active attacks against nodes running 26.06.7 or earlier, warning that funds held in routing channels could be at risk.
A seven-day live test moved $750,000 in obligations between Lloyds Banking Group and Visa using the stablecoin USDC, with funds reaching Visa in under an hour, including over a weekend.
In a September 27 essay, Vitalik Buterin argues Ethereum has moved far beyond its Bitcoin-inspired origins and will be transformed almost entirely by 2030, with the PeerDAS upgrade marking the true start of that shift.
A joint report from the EBA, ESMA and EIOPA warns that quantum computing could undermine cryptographic systems underpinning Bitcoin before commercially viable quantum machines even exist.
Deutsche Bundesbank has become the first institution to self-host Matter Labs' Prividium framework, running a permissioned Ethereum layer-2 environment on its own infrastructure while anchoring validity proofs to the public network.
A wave of simultaneous withdrawal attempts on Rootstock, the Bitcoin sidechain formerly known as RSK, temporarily drained the UTXO inventory of its two-way bridge, pushing delays to as much as 46 hours. Developers linked the rush to fallout from a recent Liquid Network hack.
A federation of over 80 companies backs Blockstream's Liquid Network, but only 15 hold signing power over its bitcoin reserves. On September 6, that narrow multisig authorised transactions that drained nearly all of it.
