Towards External Calls for Blockchain and Distributed Ledger Technology
Joshua Ellul, Gordon J. Pace · arXiv (Cornell University) · 2021
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.
