This week Andrew Stone, the lead developer of Bitcoin Unlimited (BU), published a 42‐page paper that details the evolution of the original OP_Group proposal. OP_Group is a single OP_Code that could be added to the Bitcoin Cash (BCH) network’s scripting language in order to effectively create colored coins. However, unlike other representative token protocols like Omni or Counterparty, if the OP_Group protocol was used it would require a protocol change, and miners would validate colored coins within the confirmation of normal transactions.Earlier this week, news.Bitcoin.com reported on the upcoming Bitcoin Cash (BCH) network upgrade that will take place in November. The Bitcoin ABC development team revealed a timeline of certain goals like building and polishing the 0.18 ABC software and launching the client by October 15. However, the developers didn’t detail exactly what will be included in the next upgrade.
