Hi!

You have to download the Lyra2REv2 supported multi-hashing algo library to your node.js stratum which also have to support Lyra2REv2.

Use these: https://github.com/Kasvain/node-stratum-pool AND https://github.com/Kasvain/node-multi-hashing

Both works, I'm using those in the official pool. Both have a corrected multiplier for Lyra2RE old and Lyra2REv2 new version.

You'll figure out the nomp directory structure. Clone both to right place and do necessary preparations, look at node_modules directories so you see where the original nomp stratum and its multi-hashing library is located at.

Look at algoProperties.js in the node-stratum-pool, you'll see that algorithm names for configs are "lyra2re" and "lyra2v2" exactly.

You can also PM or visit at official Lyrabar channel ##lyrabar if need help quick.
