CoinVoice recently learned that Starknet announced on social platforms that it will upgrade to SHARP v6.0. The upgraded features include application recursion, Rust implementation, and new arithmetic circuits.
Starknet will use applied recursion in the v0.13.2 upgrade to reduce block times at no additional L1 cost. This will reduce confirmation times by a factor of 7, from about 15 seconds to about 2 seconds. [Original link]
