Episode 14.X (14.1) of our Testnet is bringing some BREAKING changes. Therefore, before going into the updates, please check the instructions below, since they are very important. If you want to understand the scale of those changes, you can follow this link and see that we deleted more 21,000 lines of code and added more than 27,000.

Before going into the list of changes, instructions, and our latest figures, we wanted once more to thank all the community for its support for over a year already (14 months to be precise). With the first projects starting to build on Massa, improving our communication and the launch of an Alpha and then Beta version of our Ambassadorship program, we believe figures are going to continue to increase and hope to please you.

Finally, because everyone waits for it: our testnet is live. scoring should start (but it is NOT SURE YET), on Monday, September 19 2022, 09:40 UTC. Scoring should stop on Thursday, September 29 2022, 10:08 UTC. Why is it not sure yet about the beginning of the scoring? Due to the numerous changes in our code, we need first to monitor that there are no bugs or new memory leak. Also, as you can see, we launched for the first time the testnet with already 3,000 tx/s (!!!).

Instructions to follow for this Episode:

CRITICAL: for those who had installed the bugged TEST.14.0, please delete the storage/peers.json file or you might have banned the bootstrap nodes.

Most important changes:

  • Massive increase in performances
  • Change on the API, at the endpoint level
  • As soon as there is an execution failure at the level of an operation, an event is emitted, which makes it possible to trivialize the errors
  • Client output changed

To see the full (and massive list) of changes, please follow this link.

Conclusion of the Episode 13, figures:

  • Nodes: 7000+
  • Transaction Throughput: 0 tx/s (we did not send transactions during Episode 13 due to a memory leak, fixed with Episode 14)
  • Block Throughput: 1.99 b/s
