Towards External Calls for Blockchain and Distributed Ledger Technology
This addresses a fundamental limitation for blockchain developers and users, potentially expanding functionality in decentralized applications.
The paper tackled the problem of blockchain systems being unable to execute external calls due to deterministic state requirements, and demonstrated a method enabling blockchain and distributed ledger technologies to perform such calls from within the system.
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.
