Leveraging OP_RETURN

Inscriptions use OP_RETURN opcode to inscribe data onto the Bitcoin blockchain. This is how Satschain inscribes immutable Satschain transactions (which are EVM like) directly onto the Bitcoin, and thus borrowing Bitcoin’s Data Availability and Security.

The Satschain indexers detect transactions with valid execution instructions within the OP_RETURN field. These transactions undergo validation to ensure adherence to predetermined criteria before being processed in an EVM-compliant execution environment.
