## ETH-1 node

### Generate account

requiring for:
- allocate initial founds
- miner
- single consensus validator
- contract deploying

````shell
./geth account new

### Start ETH-1 node

Start node with console mode to following contract deploy

````

### Deploy contract `solidity_deposit_contract`

https://github.com/ethereum/consensus-specs/blob/master/solidity_deposit_contract/deposit_contract.json  
value of proprty of __"bytecode"__ contains the bytecode of the contract

1. Open ETH-1 node console
    ````shell
   ./geth attach .data/node-1/geth.ipc 
    ````
2. Deploy contract by send transaction

3. Retrieve:
   + contract address
   + hash of contract block
   + number of contract block

````
