We don't have an exact target date, however the public testing of our Testnet has gone very smoothly so far. We will release the mainnet version of VeriBlock when we are confident that the code performs as expected and that all of the network parameters (reward schedule, incentive structure, blocktime, etc.) are at optimal values.



No, the Antminer A3 for SIA is for BLAKE2b, whereas vBlake is a modified version of BLAKE2b that introduces additional rounds, even-output-distributed 3-input logic functions, and different rotation values. That being said, a vBlake ASIC is possible to manufacture, and some of the work done in designing a BLAKE2b ASIC can be re-used in designing a vBlake one.
