The Fantom Foundation announced the release of a new version of the Fantom mainnet (go-opera version 1.1.2-rc.5), the upgrade includes significant improvements in P2P and event/block processing, which shortens event/block processing time by about 30% ; Genesis file processing is up to 3 times faster (except archived Genesis files). In addition, the new version has made some adjustments to the database layer, which can integrate multiple data storage types (LevelDB and PebbleDB), and also supports database batch processing for genesis processing and desynchronized data refresh.
