Bitcoin As A State Transition System

...ate key associated with the owner's address, and one or more outputs, with each output containing a new UTXO to be added to the state. The state transition function ...

Scripting

...wal amounts—a UTXO can only be spent in its entirety, with change sent to a new output. A script cannot, for example, limit withdrawals to a maximum of X per day whil...

Code Execution

...nning the EVM with the same input state and transaction must arrive at the same output state, ensuring consensus across the network. The EVM provides three distinct ...

Technology Stack

...allows up to 80 bytes of arbitrary data to be included in a Bitcoin transaction output without creating unspendable UTXOs. This embedding approach means that Omni Lay...

Introduction

...oH is implemented as a sequential computation — a SHA-256 hash chain where each output is used as the input for the next hash. Because SHA-256 is a pre-image resistan...

Proof of History

...h function — specifically SHA-256 — that is run continuously, with the previous output used as the next input. Periodically, the current count and hash output are rec...

Proof of History Sequence

...an. This counter serves as the canonical "clock tick" for the network. The PoH output is recorded as a series of entries, each containing the counter value, the hash...

OP_RETURN and Data Applications
