Raph, the new chief maintainer of the Bitcoin protocol Ordinals, posted on Twitter that version 0.6.0 of the Ordinals protocol has been released, which enables the recognition of more types of inscriptions, such as “curse inscriptions.”

Ord.io co-founder Leonidas.og interpreted that many previously unrecognized inscriptions are now indexed as "cursed inscriptions" by the Ordinals protocol. Users will be able to trade them after the market is upgraded to 0.6.0; there were more than 70,000 invalid inscriptions before the version went online. Normal inscriptions are assigned a positive number, while cursed inscriptions are assigned a negative number. The first cursed inscription was -1, and now it is -71,508. The protocol sets a block activation height that can index a specific type of cursed inscription as a normal positive inscription. Although the positive inscription numbers will never change, the numbers of negative inscriptions can and will change. If new special cases are discovered and new types of cursed inscriptions are added. Existing cursed inscriptions will be reindexed and new cursed inscriptions will be inserted, which will cause the negative inscription numbers to change. (Planet Daily)
