I don't understand the benefits of running own blockchain. Its usually done in development with free software like ganache, but in production its more beneficial to be a part of larger more secure blockchain. I'd like to hear explanation on why is that kind of blockchain better than ethereum main network.
Sure, so there are two main scenarios here:
1. Use it as a testnet. So you test your project, your smart contracts, your tokens economy before hitting public blockchain where there are transaction fees, everything is slower and cost of mistake is much higher.
2. Private enterprise blockchains. There are numerous use cases where this is preferred. For example, supply chain partners each run a node to track shipments via common ledger. Or a consortium of banks who need to swap some mutual financial instruments. They don't need and don't want to expose the data to public blockchain.
In both cases there are existent solutions but you need to spend from hours to months. We've wrapped intuitive web interfaces and developer friendly APIs around Ethereum so project administrators and users can see the distribution of tokens, make new issuances, transfers, access crypto wallets, monitor transactions, network parameters etc.
