Plasma Cash - ERC721/ERC20/ETH Supported

Installation and Loom SDK integration

To see the integrations run against the Loom SDK you must download the loom SDK, refer to https://loomx.io/developers/docs/en/basic-install-osx.html.

Under the loom_test directory there are all the samples in Go, that directly interact with Loom SDK. If you have cloned the repo and go dependencies are not found, in loom_test try:

export GOPATH=$GOPATH:`pwd`

Demo Flow

  1. Alice registers and is given coins 1-5 from the token contract
  2. Alice deposits Coin 1, Coin 2, Coin 3 in the plasma chain
  3. 3 Deposit Blocks have been generated in the child chain, each one having 1 UTXO at slots 0,1,2 respectively
  4. Alice sends Coin 1 to Bob, adding the transaction to the current block.
  5. Operator calls submitBlock, checkpointing the block merkle root which includes the transaction that gives ownership to Charlie - At this point, both the child chain and the root chain, have checkpointed Alice's transaction at block number 1000.
  6. Bob transfers the previous UTXO to Charlie and the operator submits that block as well
  7. Charlie tries to exit Coin 1, Alice & Bob do not challenge
  8. After the challenge period passes, Charlie is able to withdraw his coin
