Hyperledger Global Forum 2021

The amount of disk storage needed to operate a "full" node in the Ethereum ecosystem has always been a challenge. The needs to balance full current states for new transactions against storage needs for full historical queries is often misunderstood. Measurements of needed disk space vary from 400 GiB to 6TiB or more depending on use cases to run a mainnet node. Bonsai Tries is Hyperledger Besu's next-generation storage layout designed to address some of these concerns. It provides a minimal impact to full sync while allowing full historical transaction execution capabilities with large savings in space. This approach also limits the long term growth of a full node. In this demo the methods used to achieve this savings will be shown as well as live demos of some of the key features.
