This is a reference implementation of a user interface showcasing the Syscoin <=> NEVM bridge. It will create a SPV proof of Syscoin burn transactions post to the relay smart contract which will validate and call a Relay contract which uses VaultManager to transfer from and to.
On the way back to Syscoin. An SPV proof of the NEVM transaction is created using eth-proof and will call a burn function from the VaultManager base of the Syscoin Token contract that holds the tokens. It's purpose is to store and transfer tokens and the function parameters are used via ABI data to detect the value of the burn once Syscoin consensus reads the transaction data.
Syscoin itself enforces the SPV proofs of existence of transactions between the chains. The full EVM and UTXO states are known to each other and validated 1:1 for each block. Syscoin nodes run a custom version of Geth which validates NEVM blocks and speaks to Syscoin over ZMQ socket transport layer. The Transaction root is queried for when a Syscoin mint transaction is created (when NEVM contract transfers Syscoin tokens to the Vault Manager contract). The calculated Transaction Root must match the Transaction Root saved locally by each node which validates that the NEVM transaction was valid and subsequently transferring to the user. The total supply of Syscoin will remain constant throughout the process as the bridge represents a zero-sum game.
