Install ethereum

$ brew install ethereum

prepare node

Following procedure can be done automatically with eth_node_init.sh script. You can also use eth_node_start.sh to start private network node configured previously.

Create two accounts. First one:

$ geth --datadir accounts/ account new
Password: test
Repeat password: test

Your new key was generated

Public address of the key:   0x3Ae3F64B827E51b1A49c57a5CAfF88f60AC68816
Path of the secret key file: accounts/keystore/UTC--2019-09-09T14-51-24.097691000Z--3ae3f64b827e51b1a49c57a5caff88f60ac68816

And second one:

$ geth --datadir accounts/ account new
Password: test
Repeat password: test

Your new key was generated

Public address of the key:   0xDCB73f4C6A71023434748B0086C65262949A8819
Path of the secret key file: accounts/keystore/UTC--2019-09-09T14-58-08.613801000Z--dcb73f4c6a71023434748b0086c65262949a8819

Setup genesis

$ puppeth
Please specify a network name to administer (no spaces, hyphens or capital letters please)
> network1

What would you like to do? (default = stats)
 1. Show network stats
 2. Configure new genesis
 3. Track new remote server
 4. Deploy network components
> 2

What would you like to do? (default = create)
 1. Create new genesis from scratch
 2. Import already existing genesis
> 1

Which consensus engine to use? (default = clique)
 1. Ethash - proof-of-work
 2. Clique - proof-of-authority
> 2

How many seconds should blocks take? (default = 15)
> 15

Which accounts are allowed to seal? (mandatory at least one)
> 0x3ae3f64b827e51b1a49c57a5caff88f60ac68816 //pub key of first account
> 0x

Which accounts should be pre-funded? (advisable at least one)
> 0xdcb73f4c6a71023434748b0086c65262949a8819 //pub key of second account
> 0x

Should the precompile-addresses (0x1 .. 0xff) be pre-funded with 1 wei? (advisable yes)
> yes

Specify your chain/network ID if you want an explicit one (default = random)
> 123

What would you like to do? (default = stats)
 1. Show network stats
 2. Manage existing genesis
 3. Track new remote server
 4. Deploy network components
> 2

Which folder to save the genesis specs into? (default = current)
  Will create network1.json, network1-aleth.json, network1-harmony.json, network1-parity.json
> 
INFO [09-09|18:01:46.902] Saved native genesis chain spec          path=network1.json

^C

Init ethereum node:

$ geth --datadir network1/ init network1.json
INFO [09-09|21:01:55.814] Successfully wrote genesis state

Copy private keys from accounts to node data directory

$ cp accounts/keystore/* network1/keystore/

Start node

geth --datadir network1/ -verbosity 7 --port 30301 --networkid NETWORK_ID --unlock PUB_KEY --mine console --nodiscover

where

  • NETWORK_ID - network id from genesis. In this readme it's 123
  • PUB_KEY - wen need to unlock account for mining. account pub key from genesis on question "Which accounts are allowed to seal?". In this readme it's 0x3ae3f64b827e51b1a49c57a5caff88f60ac68816`

So for out setup we have:

geth --datadir network1/ -verbosity 3 --port 30301 --networkid 123 --unlock 0x3ae3f64b827e51b1a49c57a5caff88f60ac68816 --mine console --nodiscover

Eth console

Send transaction

We have two accounts. Lets send money from genesis prefunded account specifiend on question "Which accounts should be pre-funded?". In this readme it is 0xdcb73f4c6a71023434748b0086c65262949a8819 with password test

> personal.unlockAccount("0xdcb73f4c6a71023434748b0086c65262949a8819", "test")

"0xae76939b961c4c2fc86a741a54c1058af724110e78fac1d1f308670a90344e93"

run

Generation of secret key takes a lot of time here. So if you know it in advance better provide it as a --secret.

If secret key is unknown, it can be generated from your account keystore json part. Provide the part of json as --crypto parameter.
