Towards External Calls for Blockchain and Distributed Ledger Technology

TL;DR

This paper challenges the common belief that blockchains cannot perform external calls by introducing a method that enables such calls to be initiated from within the blockchain or DLT, expanding their capabilities.

Contribution

The paper presents a novel method allowing blockchains and DLTs to perform external system calls, overcoming a longstanding limitation.

Findings

Demonstrates a functional method for external calls in blockchain systems

Shows that external calls can be initiated from within the blockchain

Challenges the assumption that blockchain systems are deterministic only

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.
