Zcash has recovered about 45 percent from its recent low after developers proposed the Ironwood upgrade to address a supply verification issue. The privacy-focused cryptocurrency traded near $437 on Monday, though it remains down 22 percent for the week. The move comes after a patched bug in the Orchard pool triggered last week's sell-off.
Zcash announced plans to introduce quantum-recoverable wallets within a month and achieve full post-quantum security by 2027. The privacy-focused cryptocurrency also outlined scaling upgrades during an event in Miami.

Andrew Gault warns that bitcoin faces a greater quantum threat from encrypted messages moving between institutions than from exposed wallet keys. He points to a harvest-now-decrypt-later strategy already in use by adversaries.
Researchers at the University of Science and Technology of China have developed the Jiuzhang 4.0 photonic quantum computing prototype, which manipulates 3,050 photons and sets a new record.

New analysis reveals that over 30 percent of Bitcoin's supply sits in wallets vulnerable to future quantum attacks, with exchanges holding a disproportionate share of the exposure. A startup has proposed a soft-fork solution to protect even dormant holdings, including Satoshi Nakamoto's estimated 1.1 million coins.
Cryptocurrency exchange OKX has published a new cross-chain Agent Payments Protocol (APP) to enable autonomous financial interactions among AI agents. The framework supports agent-to-agent payments, escrow, and automated transactions in business settings. It builds on OKX's Agentic Wallet and Payment SDK with cross-chain capabilities.
