The transaction timestamp was originally implemented in Peercoin by founder Sunny King. Its purpose was to allow for an easier way to handle coin age in the client. It is a unique part of Peercoin’s protocol which does not exist in Bitcoin. However, its inclusion back in 2012 consequently rendered Peercoin incompatible with a large number of tools, services, and infrastructure primarily developed for Bitcoin. Integrating Peercoin with these tools and services had required additional time and effort to be spent on complex workarounds to support the timestamp feature.
The removal of the transaction timestamp from the protocol will effectively eliminate Peercoin’s incompatibility issues. Once the protocol switches to v0.11, it will become much easier for developers to integrate with existing infrastructure such as Rosetta, Lightning Network, Atomic Swaps, DeFi, DEXes, and much more. This change will open up Peercoin to a number of new opportunities for future developments and integrations.
