Title. Foundations of Blockchain Protocols
Abstract. The rise of bitcoin and other cryptocurrencies puts forth a
wealth of interesting problems in distributed systems and cryptography that
relate to building decentralized systems. In this talk, we discuss what is
the exact problem that the bitcoin protocol solves and then go on to
investigate whether and in what ways the protocol can be improved. The
protocol itself will be abstracted in a simple algorithmic form, termed as
the bitcoin backbone, and subsequently provable properties like chain
quality, common prefix and chain growth will be detailed. The concept of a
robust transaction ledger will be defined, as captured by two basic
properties, persistence and liveness. Alternatives to the main protocol
such as GHOST will be overviewed as well as the relation of the defined
properties and protocols to the consensus problem.
