Abstract
Distributed Ledger Technologies (the agnostic term for Blockchain and related technologies) have recently become one of the most controversial and debated topics in industry and academy alike. They represent a way to realize databases of replicated, shared, and synchronized digital data, spread across multiple agents. Rather than having a central server, distributed ledgers make use of a peer to peer consensus system to ensure the consistency of the database, across every copy in the network. The emergency of this technology enabled, in the past ten years, the proliferation of well known cryptocurrencies (e.g., Bitcoin, Ethereum, IOTA) and promises to reshape the way we think about business and trust, in the Internet of Things era. In this chapter, after a brief introduction to Distributed Ledger Technologies in the context of the sharing economy, we present and compare the two main architectures on which distributed ledgers are built: the Blockchain and Directed Acyclic Graphs.
