You can mine from the in-wallet miner starting now, pools will be available soon.
First 250 blocks are low reward (1 WRP) to avoid instamine, the algo will start at scrypt-n and change to a custom implementation of LYRA2 at block 500. This implementation is exactly the same as ZCoin's and it was deliberately coded that way so you can use OCMiner's CPUMiner-Multi fork available here: https://github.com/ocminer/cpuminer-xzc.
