## 0x Devnet
|
||||
|
||||
A private, single-node PoA Ethereum network for testing purposes only. It uses
|
||||
Geth and the PoA implementation called "Clique".
|
||||
|
||||
## Installation
|
||||
|
||||
The devnet requires Docker to run (the latest version is recommended).
|
||||
|
||||
In the package root directory, run:
|
||||
|
||||
```
|
||||
docker build -t 0x-devnet .
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
To start the network, run:
|
||||
|
||||
```
|
||||
docker run -it --rm -p 8501:8501 0x-devnet
|
||||
```
|
||||
|
||||
Depending on your OS and how you installed docker, you may need to prefix any
|
||||
docker commands with `sudo`.
|
||||
|
||||
The Docker container exposes the JSON RPC API at port 8501, and this is the
|
||||
primary way you are expected to interact with the devnet. The following
|
||||
endpoints are supported: `personal,db,eth,net,web3,txpool,miner,debug`.
|
||||
|
||||
You can stop the network with `docker stop` and it will automatically clean up
|
||||
after itself. (`docker stop` typically requires you to use `docker ps` to find
|
||||
the name of the currently running container).
|
||||
|
||||
### Configuration
|
||||
|
||||
The devnet network only has a single node and using PoA instead of PoW. That
|
||||
means that one node, called the "sealer", is the ultimate authority for
|
||||
validating transactions and adding new blocks to the chain. Since there is no
|
||||
PoW it also means that mining does not require significant computational
|
||||
resources. You can learn more about PoA and the Geth-specific implementation
|
||||
called "Clique" in [EIP-225](https://github.com/ethereum/EIPs/issues/225).
|
||||
|
||||
The address of the "sealer" is `0xe8816898d851d5b61b7f950627d04d794c07ca37`. The
|
||||
password associated with the account is "password" and the (encrypted) private
|
||||
keys are visible in the **node0/keystore** directory. This account is already
|
||||
"unlocked" in the Geth node by default, so you can do things like sign and send
|
||||
transactions from this account using the JSON RPC endpoints directly.
|
||||
|
||||
There are also a number of other addresses that have hard-coded starting
|
||||
balances for testing purposes. You can see the details in the **genesis.json**
|
||||
file. All of these accounts are also unlocked by default.
|
||||
|
||||
### Mining
|
||||
|
||||
The node will automatically (nearly instantly) mine a block whenever new
|
||||
transactions are added to the transaction pool. If there are no transactions in
|
||||
the pool, it will wait.
|
||||
|
||||
To stop mining, use the
|
||||
[`miner.stop`](https://github.com/ethereum/go-ethereum/wiki/Management-APIs#miner_stop)
|
||||
method.
|
||||
|
||||
To start mining again, you can use the
|
||||
[`miner.start`](https://github.com/ethereum/go-ethereum/wiki/Management-APIs#miner_start)
|
||||
JSON RPC method.

||||
