What Is OPNEXT?

OPNEXT focuses on the most technically active area of Bitcoin protocol development — script opcodes and covenant proposals. The Bitcoin community has been engaged in an extended technical discussion about how to expand Bitcoin's scripting capabilities: proposals like OP_CAT, OP_CTV, LNHANCE, and others that could enable new classes of smart contracts, vaults, and layer-2 protocols while maintaining Bitcoin's security properties.

This is deeply technical territory that most general Bitcoin conferences don't cover in depth. OPNEXT brings together the developers, researchers, and protocol contributors who are actually building and evaluating these proposals — 150 people in a focused single-day format is ideal for the kind of substantive technical debate these topics require.

The Times Center, New York City

The Times Center is a premier conference venue in Midtown Manhattan operated by the New York Times. It's an excellent setting for a high-signal technical event — sophisticated, central, and well-equipped. New York in April is vibrant, with spring arriving and the city operating at full energy.
