Taraxa Weekly Tech Update: 2019 Week 42

This week saw the merge of a major codebase refactoring for an improved full node lifecycle and code verification, as well as the start of our second two-week sprint towards an updated testnet at the end of the month. We continue our work to build off the successful completion of our previous big push to reach the launch of Albidum; the initial version release of our testnet.

Continuing in our scheme of testnet versions named after dandelion species, we plan to follow that up with the launch of an updated version Aphrogenes by the end of October.
