How can I convert a Token e.g. TOT(built on ethereum) to Coin TOT e.g. with same name and same value in another public blockchain?
Or is there any way to convert token value to new coin using new blockchain network?
If I understood it correctly, you want to have your own blockchain based on your token.
https://poa.net can help you with that by using bridge technology:
No need to suicide your contract or something, and you can keep your ERC20 listed if it was listed on exchanges.
Hopefully you included a suicide function to destroy your old smart contract such that no new tokens are created. Basically, the easiest way to do this is to first freeze the assets of the old token.
If the chain you're creating is EVM-like, you can simply create a new genesis block with coin values assigned to each token holder.
If you're working with a brand new blockchain interface, you're going to need to communicate directly with your token holders somehow in order to give them the private key holding their coins on the new chain. Instruct them to then move the coins into an address made by a private key that you dont own.
Tezos did this by collecting emails of all token purchasers. I am hoping you did not run an ICO and are now only figuring how to launch your chain.
