🚀 A fresh security debate is pushing major blockchains to revisit wallet cryptography. Europol says exposed public keys—not blockchain hash functions—are the main long-term quantum risk and recommends a phased migration to resistant systems. Glassnode estimates about 6.04 million $BTC, or 30.2% of issued supply, already sits behind visible public keys. Ethereum researcher Justin Drake separately warned that AI-accelerated mathematics could shorten attack timelines, while Vitalik Buterin stressed that no practical break has been demonstrated and rushed migrations can cause losses. The issue also reaches $ETH and $SOL: active Ethereum accounts reveal keys after signing, while Solana accounts expose them by design. The debate is about preparation, not evidence of a current exploit. #TrendingTopic #BTC #HotTrends #ETH #solana
