Are there any good tutorials or resources for sidechain development or are these just specialized private chain pegged to the Ethereum network?

There are more resources coming on line If your looking for a private block-chain, for example your own sidechain on ETH with and a choice of consensus, look at Ark with its modular plugin system. Ark uses what it calls "smart bridges" to connect to a public ETH,to provide services or even act as interfaces for other third-party services. Its most developed sdk is javascript.

see ark for a detailed tech outline to the stack, they have a cookbook with code snippets there as well

There are no tutorials, because the state of the art is still in Research & Development and nobody has deployed a true sidechain yet.

As far as I know, at the moment there is no decentralized way to set up sidechains. For example, one of the most popular projects Rootstock (RSK) is using a "federation" e.g. centralized wallet do to the pegging.

Wwhy would one need an ethereum sidechain if ethereum is turing complete? That just makes little sense. It's not a scalability conversation, that's a stupid way of scaling. It's the equivalent of fixing something with duct tape.

For a blockchain like bitcoin it makes somewhat sense because it can extend functionality of the protocol but even then there's issues. Atomic swap is nothing but a fancy word for an automated escrow and there's big potential hazards like centralization (see LN hubs), fraudulent swaps, ... . Not to mention it's only possible through local daemon.

  • For ranting needs, please engage the likeminded people in Reddit, but leave it out from the professional conversation. – Mikko Ohtamaa Mar 3 '18 at 12:27

    Even if these are the facts and correct, this is not an answer to the question but starts with another question. – Mikko Ohtamaa Mar 3 '18 at 14:44
