Towards External Calls for Blockchain and Distributed Ledger Technology

Joshua Ellul, Gordon J. Pace

Abstract

It is widely accepted that blockchain systems cannot execute calls to external systems or services due to each node having to reach a deterministic state. However, in this paper we show that this belief is preconceived by demonstrating a method that enables blockchain and distributed ledger technologies to perform calls to external systems initiated from the blockchain/DLT itself.
