Title: The process and the blockchain: A story of miners
Abstract: A process describes the temporal evolution of a system. Capturing the rules that govern its control flow helps to understand the boundaries of its behaviour. That is the essence of the research field called process mining.
A blockchain can be defined at large as an immutable distributed ledger on which transactions between peers are recorded. Transactions are cryptographically signed and are meant to transfer digital commodities between parties. The validation and publication of transactions is the job of the nodes called miners.
Lately, the blockchains have undergone a paradigm shift from mere electronic cash systems to a universal platform endowed with internal programming languages, on top of which decentralised applications can be built. That has been the turning point enabling the execution of processes on blockchains.
This talk revolves around recent advancements in research concerning the execution and mining of processes on the blockchain. The discourse will include a focus on the automated discovery of behavioural specifications from process data, and, in turn, on the extraction of process data from blockchains.
