“…We have in a short paper [19] (and pre-print [18]) presented the initial approach demonstrating that active external calls can be supported by blockchains (including public ones) whilst avoiding the problems mentioned above. The proposed solution allows for miners (or validators) to actively make external calls by requiring services to respond with signed input which will be written together with the associated transaction.…”

Blockchain and other distributed ledger technologies have enabled peer-to-peer networks to maintain ledgers with an immutable history and guaranteed computation, all carried out without the need of trusted parties. In practice, few applications of blockchain are closed i.e. do not interact with the world outside the blockchain, and various techniques have been proposed and used to handle such interaction. One problem is that it is widely accepted that, due to the decentralised nature of blockchain networks and constraints to ensure trust and determinism, such communication can only flow into the blockchain, and that blockchain systems cannot initiate and execute calls to external systems or services. In this paper we show that this misconception is preconceived by building on our previously presented solution to demonstrate that such calls can be directly initiated from the blockchain itself in a feasible and efficient manner.
