Deposit Contract
A validator will deposit 32 ETH to the deposit
contract. The contract will generate a log showing the validator as a
qualified validator.
The deposit is considered to be burned. As you burn the 32 ETH to participate,
the beacon chain will see it and will credit the validator with the validator bond,
At some point in the future, after a hard fork,
the original deposit + interest can be withdrawn back on one of the shards.
To call the registration function, it takes arguments of pubkey,
proof_of_possession, withdrawal_credentials.
If the user wants to deposit more than DEPOSIT_SIZE ETH, they would
need to make multiple deposit calls.
When the contract publishes the ChainStart log, beacon nodes will
start off the beacon chain with slot 0 and last recorded block.timestamp
as beacon chain genesis time.
The registration contract generate logs with the various arguments
for consumption by beacon nodes. It does not validate proof_of_possession
and withdrawal_credentials, pushing the validation logic to the
beacon chain.
How to generate bindings for vyper contract
This requires that you have vyper and abigen installed in your local machine. Vyper: https://github.com/ethereum/vyper Abigen: https://github.com/ethereum/go-ethereum/tree/master/cmd/abigen
To generate the abi using the vyper compiler, you can use
docker run -v $(pwd):/code ethereum/vyper:0.1.0b12 -f abi /code/depositContract.v.py > abi.json
Then the abi will be outputted and you can save it in abi.json in the folder.
To generate the bytecode you can then use
docker run -v $(pwd):/code ethereum/vyper:0.1.0b12 /code/depositContract.v.py > bytecode.bin
and save the bytecode in bytecode.bin in the folder. Now with both the abi and bytecode
we can generate the go bindings.
bazel run @com_github_ethereum_go_ethereum//cmd/abigen -- -bin $(pwd)/bytecode.bin -abi $(pwd)/abi.json -out $(pwd)/depositContract.go --pkg depositcontract --type DepositContract
How to execute tests
bazel test //contracts/deposit-contract:go_default_test
Run with -v option for detailed log output
bazel test //contracts/deposit-contract:go_default_test --test_arg=-test.v --test_output=streamed
