NOTICE: This is an experimental software, don't run in production.

Quickstart

Please install Docker Compose in advance.

$ cd _docker
$ docker-compose up --build -d

NOTICE: The private keys used in the following process are generated by ganache-cli with --deterministic option. Do not use them in production.

• Operator
  • address: 0x90f8bf6a479f320ead074411a4b0e7944ea8c9c1
  • privkey: 0x4f3edf983ac636a65a842ce7c78d9aa706d3b113bce9c46f30d7d21715b23b1d
• Alice
  • address: 0xffcf8fdee72ac11b5c542428b35eef5769c409f0
  • privkey: 0x6cbed15c793ce57650b9877cf6fa156fbef513c4e6134f022a85b1ffdd59b2a1
• Bob
  • address: 0x22d491bde2303f2f43325b2108d26f1eaba1e32b
  • privkey: 0x6370fd033278c143179d81c5526140625662b8daa446c22ee2d73db3707e620c

STEP 1 : Deploy root chain contract

Operator deploys the root chain contract.

$ docker-compose exec child plasma deploy --privkey 0x4f3edf983ac636a65a842ce7c78d9aa706d3b113bce9c46f30d7d21715b23b1d

STEP 2 : Deposit

Alice deposits 1 ETH. Operator creates block#1 that includes Alice's deposit tx. Alice receives 1 ETH on the child chain.

$ docker-compose exec child plasma deposit make --amount 1000000000000000000 --privkey 0x6cbed15c793ce57650b9877cf6fa156fbef513c4e6134f022a85b1ffdd59b2a1

STEP 3 : Transfer

Alice sends 0.5 ETH to Bob on the child chain.

$ docker-compose exec child plasma tx post --pos 1000000000 --address 0x22d491bde2303f2f43325b2108d26f1eaba1e32b --amount 500000000000000000 --privkey 0x6cbed15c793ce57650b9877cf6fa156fbef513c4e6134f022a85b1ffdd59b2a1

Operator creates block#2.

$ docker-compose exec child plasma block fix

Alice confirms the transfer tx.

$ docker-compose exec child plasma txin confirm --pos 2000000000 --privkey 0x6cbed15c793ce57650b9877cf6fa156fbef513c4e6134f022a85b1ffdd59b2a1

ref. Why do/don't we need two phase sends plus confirmation

STEP 4 : Start exit (invalid)

Alice starts invalid 1 ETH exit.

$ docker-compose exec child plasma exit start --pos 1000000000 --privkey 0x6cbed15c793ce57650b9877cf6fa156fbef513c4e6134f022a85b1ffdd59b2a1

STEP 5 : Challenge exit

Bob challenges the Alice's invalid exit successfully.

$ docker-compose exec child plasma exit challenge --pos 1000000000 --vspos 2000000000 --privkey 0x6370fd033278c143179d81c5526140625662b8daa446c22ee2d73db3707e620c

STEP 6 : Start exit (valid)

Bob starts valid 0.5 ETH exit.

$ docker-compose exec child plasma exit start --pos 2000000000 --privkey 0x6370fd033278c143179d81c5526140625662b8daa446c22ee2d73db3707e620c

STEP 7 : Process exits

2 weeks have passed.

$ curl -X POST http://127.0.0.1:8545 --data '{"jsonrpc": "2.0", "method": "evm_increaseTime", "params": [1209600], "id": 0}'
$ curl -X POST http://127.0.0.1:8545 --data '{"jsonrpc": "2.0", "method": "evm_mine", "params": [], "id": 0}'

Operator processes exits. Bob receives 0.5 ETH on the root chain.

$ docker-compose exec child plasma exit process --privkey 0x4f3edf983ac636a65a842ce7c78d9aa706d3b113bce9c46f30d7d21715b23b1d
