Solana’s latest upgrade, version 1.16, aims to improve security and increase validator activity. The upgrade includes features related to Ethereum and has been tested on the Testnet since June 7th. The development team encountered some issues with RPC nodes and called in security firm Halborn to audit the upgrade. The upgrade also introduces confidential transfers, which enhance privacy and encrypt transactions and balances of SPL tokens. For validators, the upgrade reduces RAM usage for indexing accounts from 120GB to 39GB. Solana plans to release another upgrade, version 1.17, in the next three months.
