Crypto as the New Internet Backbone: Inside a16z’s “Big Ideas 2026

a16z's Big Ideas 2026 report lays out 17 main crypto ideas. Instead of seeing blockchains as just another asset, they frame them as essential for the internet. The main thing is the growth of AI agents. They think AI could outnumber human finance people by 100 to 1! To make safe deals on a big scale, these agents will need crypto Know Your Agent (KYA) IDs that link them to real owners. The idea is that payments will become basic and unseen, like x402—simple protocols that let agents move money instantly. This would push stablecoins, banks, and regular payment systems into the background, using them as basic infrastructure.

The report mentions that stablecoins and tokenized real-world assets (RWAs) are becoming more important. Stablecoins might handle around $46 trillion in 2025, which is three times what Visa processes! They will also connect with local payment methods using QR codes and fast payment systems. Credit markets are starting to happen on the blockchain itself, not just wrapping assets from the old financial system. Also, things like perpetuals (a type of derivative) are favored over traditional versions of securities. At the same time, prediction markets are improving with AI oracles, and zkVMs are enabling verifiable cloud computing, which allows computations to be fully checked.

Privacy and security are becoming key advantages. Blockchains that focus on privacy can create loyalty because of data problems on bridges. This encourages users to stay where their data is best protected. New ideas like secrets-as-a-service, quantum-safe messaging, and formal DeFi safety rules are changing how we handle privacy and security on the blockchain. These trends, which include stablecoins/RWAs, AI agents, privacy/security, and basic infrastructure/laws, create a future where crypto provides the trust, identity, and verification for an internet economy driven by agents and that can be programmed.
