Lily Liu, president of the Solana Foundation, emphasized the growing role of stablecoins and blockchain in global financial infrastructure during her speech at Consensus Miami 2026. Liu highlighted recent integrations by Meta and Western Union of stablecoin payments on Solana as evidence of blockchain's transition from speculative technology to practical infrastructure. She noted that enterprises require fast, cheap, and liquid payment systems, which blockchain provides. Liu also discussed the potential of blockchain in AI-driven "machine economies," where AI agents transact autonomously. She argued that blockchain's ability to handle micropayments and real-time payment streaming makes it ideal for such transactions, unlike traditional credit card systems. Liu defended Solana's recent security interventions and projected that blockchain's future role could extend into "internet capital markets," facilitating global capital access.
