hi @victor, After trying hard, I switched to use docker-compose ([this repo](https://github.com/enigmampc/discovery-docker-network#installation)) to install & launch the testnet instead. I think the issue above, relating to some native libs’s dependencies. Just have 1 question, if I use the repo above to launch the testnet, is it the same as discovery-cli does? And am I connecting to my local testnet or Enigma Discovery testnet? ---

It’s very similar though the repo you mention does not expose the ports needed for you to interact with the network from the host side. In either case, you’ll be connecting to your local testnet (dockerized) as this is all what Enigma has released to date. There is no such thing as a public Enigma Discovery testnet, yet; that’s our next milestone. ---

Thank for fast reply, @victor. So for now, I’ll use my local container to test first. I’m using Enigma for a dApp demo. Hopefully we will have the public Enigma DiscoveryTestnet soon. I’m so excited. By the way, if you said that, I suppose that I’m using the software resources from my machine to launch the local Discovery testnet, am I correct? > # HD Wallet > > Mnemonic: myth like bonus scare over problem client lizard pioneer submit female collect > Base HD Path: m/44’/60’/0’/0/{account\_index} And the things are such as Available Accounts, Private Keys, etc… shown on logs of running launch bash, they are test accounts & random keys which my local testnet provided, aren’t they? ---

@arookie, yes that is correct. All the resources that you see/use are local to your machine, and all the Ethereum accounts, keys, amounts are from a local Ganache/Truffle instance, so you are im full control and it’s all a test envirnoment. There is nothing at stake 🙂 it’s a sandbox ---

Has anyone solved this issue, I have tried all the possible suggestion’s given in this thread yet I am not able to install discovery. ---

Sounds like it didn’t install properly afterall, what errors are you getting? BTW secret contracts are coming to a new blockchain, please check out [enigma-blockchain-contracts-guide](https://github.com/enigmampc/enigma-blockchain-contracts-guide) if you haven’t already. ---

Discovery got installed and I can use the command’s but when I do discovery start After installing discovery and discovery start, (node:6639) UnhandledPromiseRejectionWarning: # (node:6639) UnhandledPromiseRejectionWarning: Unhandled promise rejection.
