BSV-21 (Beta)
BSV-21 protocol was originally called BSV-20 v2 but was renamed for clarity.
Here is a brief intro from the official documentation:
"This iteration of the BSV-20 protocol introduces a new tickerless mode functionality. Tickerless mode forgoes the first is first nature of BRC20-BTC, and allows the capabilities to have a smart contract, or an administrator, control distribution. Additionally, every transaction of a tickerless mode token forms part of a single on-chain DAG (Directed Acyclic Graph), such that the transaction can easily be tracked back to that token's genesis mint. "
