On March 30, 2026, a joint paper from Google Quantum AI, the Ethereum Foundation, and Stanford shook up the crypto community. It estimated that the physical qubit count needed to recover a private key on secp256k1 (the elliptic curve behind Bitcoin and Ethereum signatures) had dropped nearly 20x from the previous best estimate. A threat that used to sound like “millions of qubits, decades away” now reads as “under 500,000, maybe within this decade.”

The ERC-8004/8126/8196 trust stack defines three layers: agent identity, security verification, and policy-constrained execution. It identifies an agent, scores its risk, and keeps it acting within the limits an owner has set. All of that answers one question: can I trust this agent to act on my behalf?

Decentralized exchanges come in two main forms. AMMs (Automated Market Makers) like Uniswap set prices algorithmically from pool ratios and work as permissionless swap venues. Orderbook DEXes match individual buy and sell orders by price and time priority, the same way centralized exchanges like Binance or Coinbase operate. Orderbooks enable limit orders, tighter spreads with active market-making, and more precise price discovery. AMMs do not.
