  2. On the topic of blockchain and cryptocurrency: a blockchain is not a distributed ledger. A blockchain is simply a single chain directed acyclic graph of blocks in which each added block is the new root of the DAG (i.e. a graph where each vertex has a degree of 1 or 2). "Distributed ledger" is also a misnomer: all current systems use a replicated ledger, not a distributed one, within a replicated state machine. The ledger data is embedded within and distributed through the blockchain. A truly distributed ledger would be one in which transaction data is retained local to the transactors rather than replicated across the whole globe. This is theoretically possible, and it can be done without a blockchain. Satoshi Nakamoto described his innovation of using proof-of-work to order transactions as a distributed timestamping server, but global consensus is not necessary in every scenario. It is theoretically possible to create a cryptocurrency without a blockchain as typically envisioned, using correspondent credit relationships. I have done a lot of research and preliminary experiments toward this end, and I have written a number of dependency packages for the project. I expect to have a working prototype done sometime next year. The only purpose for blockchain is global consensus, and this necessarily involves throughput limitations. Globally replicated state also creates a massive data retention burden upon network participants. For most intents and purposes, blockchain is a slower, shittier database.
