Thank you very much for following up with ARPA!
However, in case you missed, the BLS-TSS-Network Repo was actually updated 2 days ago, our tech team has always been active. Please feel free to check the progress, pull request or create issues at https://github.com/ARPA-Network.
Elsewhere, you've probably read the previous article about the test methods that we use in the current internal DevNet phase, we'd like to kindly ask you to take a look if you didn't notice it: https://arpa.medium.com/arpa-bls-tss-network-devnet-c03483d761f3
Stay tuned! Public TestNet with dev and community events will come up soon!
