NEW: ECB adviser Jürgen Schaaf says digital euro alone won't challenge US dollar stablecoin dominance.  
 
Europe may need regulated euro stablecoins and private innovation to counter USD-pegged stablecoin growth.

BREAKING: Sui Research just dropped a major breakthrough in quantum transition of "some" blockchains. Unfortunately it works for Sui, Solana, Near, Cosmos and other EdDSA-based chains, but not for Bitcoin and Ethereum  
 
Here is the paper: https://eprint.iacr.org/2025/1368.pdf
 
*Afaik this is the first backward compatible quantum-safe upgrade path for blockchain wallets to avoid future forks or freezing accounts.  
 
...and why that’s huge  
 
There’s a non-zero chance that today’s wallets could become vulnerable to quantum adversaries in the coming decades.
 
While I personally doubt we’re anywhere near quantum supremacy that can break cryptography soon, the growing concerns, and new guidance from security agencies recommending algorithm upgrades by 2035, should serve as a wake-up call. Even if much of this is perception-driven, our community must be prepared to eventually transition.
 
Once quantum computers arrive, millions of wallets,  including Satoshi’s, could be drained instantly. If your public key is visible, it will eventually be cracked.
 
Lost keys, deceased owners, cold storage... all at risk (these will be the first victims).
Billions in crypto sit in “sleeping” wallets that may never be updated or transfer their assets out.
 
Our solution:
We found a way for wallets using EdDSA (e.g., Sui, Solana, Near and co) to prove ownership securely after quantum, without revealing secrets or touching the wallet to quickly transfer their coins. Surprisingly a small detail on how EdDSA private keys are derived compared to ECDSA makes a huge difference on quantum readiness. TL;DR a simple hash invocation over a seed and not directly picking elliptic curve scalars as private keys saved the game!
 
No re-signing. No address change. Zero downtime.
Just a zero knowledge proof that says: “I still control this wallet, but now signing protected against quantum hackers"
 
 Built on Ed25519 key derivation (SLIP-0010) and zk-STARKs / Ligero
 
 Works for sleeping and lost accounts, multisigs, treasuries, and cold storage
 
 Protects real users & institutions, not just future chains, but your today’s mnemonic based wallets too
 
 Developed by @SuiNetwork, @Mysten_Labs and @GeorgeMasonU applied and theoretical cryptographers, congrats to Foteini and Arnab whose help was paramount!
 
*We’re already in contact with the teams behind @ligero_inc and @SoundnessLabs, but we’ll also approach governments and major organizations like Google (which has already begun exploring Ligero ZK proofs) to pursue an implementation, and if possible, make it a global standard.
 
Maybe those who chose Ed25519 over ECDSA were lucky or just smart. Personally, I want to thank one of my first crypto instructors, Daniel Bernstein (@hashbreaker) the inventor of EdDSA, who taught at the EU ECRYPT summer school in Samos back in 2007.  He planted a spark that made me obsess over every detail of the algorithm and maybe without that, I wouldn't be here today as a scientist.

RAKBANK, l’une des plus anciennes banques des Émirats arabes unis, s’associe à Bitpanda pour permettre à ses clients d’acheter, vendre et échanger des cryptomonnaies directement depuis son application mobile en dirhams.

Ce dispositif lancé par la banque centrale brésilienne est désormais plus utilisé que les cartes bancaires et l’argent liquide. L’engouement est tel que WhatsApp a dû renoncer à un système de paiement qu’il voulait lancer localement.
 
Lancé par la banque centrale brésilienne en novembre 2020, le mécanisme est si populaire qu’il a déjà dépassé les transactions par carte bancaire et par argent liquide. Rien qu’en avril 2025, 2,677 trillions de reais (plus de 410 milliards d’euros) de paiements ont été effectués avec Pix. Ce succès immédiat s’explique notamment par la facilité d’utilisation du dispositif, estime Carla Beni, professeure d’économie à la Fondation Getulio-Vargas : « Les transferts n’engendrent aucun coût supplémentaire et l’argent arrive instantanément sur le compte de l’utilisateur. La femme de ménage ou l’électricien qui vient de réaliser une prestation peut ensuite aller...
