Block joins x402 Foundation and adds Bitcoin Lightning payments

Jack Dorsey's Block $XYZ has joined the x402 Foundation and is contributing $BTC Lightning payments to the open standard for AI-agent payments.
The integration brings Bitcoin's Lightning Network into infrastructure designed for autonomous agents to make machine-to-machine payments, expanding the payment options available through the x402 standard.
The initiative combines two emerging themes: AI-agent commerce and programmable digital payments, although adoption will depend on developer integration and real-world usage.
