What new things will emerge in crypto in 2026? A recent tweet from a16z listed 17 "big ideas," and I personally resonated with the following three: 1. Privacy Public Chains: Privacy chains will have stronger network effects than general-purpose public chains. Cross-chain token transfers are easy, but cross-chain transfers of "secrets" are difficult. This stickiness will lead to a "winner-takes-all" scenario in privacy public chains. 2. AI Agent Economy: On one hand, it's shifting from KYC to KYA, with agents starting to build trust credentials; on the other hand, it needs to support micropayments (mentioning x402) and new attribute systems, providing real-time payments to each entity that helps the agent complete tasks. 3. The Emergence of Staking Media: KOLs and media outlets can stake tokens to prove the credibility of their statements, which readers can then verify. Staking media will complement traditional media. The article also discusses stablecoins, prediction markets, US regulation, and other ideas; those interested can read it.
