Alberto Sonnino Scaling distributed ledgers: Achieving arbitrary throughput and sub-second latency

This talk describes two techniques to improve the throughput and latency of blockchain technologies. First, this talk presents the design, implementation and evaluation of some key sharded blockchains. Sharding is one of the main approaches to address blockchain scalability, the key idea is to create groups (called shards) of nodes that handle only a subset of all transactions and system state. Sharding allows blockchains to achieve linear scalability; that is, the throughput of the system is theoretically
