有没有办法部署具有自动挖矿功能且没有 gas 成本系统的私有以太坊网络？

Question

I am creating POC web app using Ganache as a Blockchain network locally. For now, I need to deploy everything to a testing server but the problem is that I still could not find the way to set up a private Blockchain network that has automining like what we have with Ganache locally also about the gas fee as well, when I develop locally I need to manually and ether to every newly created account for them to be able to make a transaction. But once when I deploy everything to the testing server, it would be better if I don't need to keep transferring ether since this is just a POC app on a private network anyway.

Any tools that I should take a look for this problem?

Thanks!

Answer 1

You are roughly describing a demo chain or a PoA chain.

OpenEthereum has a demo chain flag which uses this spec .

Alternatively, Almost all ETH1 clients support building PoA chains so you can cherry pick the EIP's you want to cinclude. Geth supports clique . OpenEthereum supports AuRa and clique.

If you want a production grade private network, i'd recommend either using AuRa or QBFT from GoQuorum.

Each client and its consensus algo have its own set of requirements like minimum number of validator nodes etc
