Eth News and Links
Mainnet
- Geth v1.10 – snap sync is shipped, though not yet enabled as nodes need to build the structure necessary for snap sync. That structure makes pruning relatively quick and gets you back to a database size of a fresh sync. Snapshots also make DOS attacks harder and increase database read capacity of node. Adds eth/66 and will drop eth/64 soon and eth/65 in the summer
