#### Defining the private genesis state Unfortunately since [the Merge](https://ethereum.org/en/roadmap/merge/) it is no longer possible
to easily set up a network of geth nodes without also setting up a corresponding beacon chain.
First, you'll need to create the genesis state of your networks, which all nodes need to be There are three different solutions depending on your use case:
aware of and agree upon. This consists of a small JSON file (e.g. call it `genesis.json`):
```json * If you are looking for a simple way to test smart contracts from go in your CI, you can use the [Simulated Backend](https://geth.ethereum.org/docs/developers/dapp-developer/native-bindings#blockchain-simulator).
{ * If you want a convenient single node environment for testing, you can use our [Dev Mode](https://geth.ethereum.org/docs/developers/dapp-developer/dev-mode).
"config": { * If you are looking for a multiple node test network, you can set one up quite easily with [Kurtosis](https://geth.ethereum.org/docs/fundamentals/kurtosis).
"chainId": <arbitrary positive integer>,
"homesteadBlock": 0,

"byzantiumBlock": 0,
"constantinopleBlock": 0,

},
"alloc": {},
"coinbase": "0x0000000000000000000000000000000000000000",
"difficulty": "0x20000",
"extraData": "",
"gasLimit": "0x2fefd8",
"nonce": "0x0000000000000042",
"mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp": "0x00"
}
```
The above fields should be fine for most purposes, although we'd recommend changing
the `nonce` to some random value so you prevent unknown remote nodes from being able
to connect to you. If you'd like to pre-fund some accounts for easier testing, create
the accounts and populate the `alloc` field with their addresses.
```json
"alloc": {
"0x0000000000000000000000000000000000000001": {
"balance": "111111111"
},
"0x0000000000000000000000000000000000000002": {
"balance": "222222222"
}
}
```
With the genesis state defined in the above JSON file, you'll need to initialize **every**
`geth` node with it prior to starting it up to ensure all blockchain parameters are correctly
set:
```shell
$ geth init path/to/genesis.json
```
#### Creating the rendezvous point
With all nodes that you want to run initialized to the desired genesis state, you'll need to
start a bootstrap node that others can use to find each other in your network and/or over
the internet. The clean way is to configure and run a dedicated bootnode:
```shell
$ bootnode --genkey=boot.key
$ bootnode --nodekey=boot.key
```
With the bootnode online, it will display an [`enode` URL](https://ethereum.org/en/developers/docs/networking-layer/network-addresses/#enode)
that other nodes can use to connect to it and exchange peer information. Make sure to
replace the displayed IP address information (most probably `[::]`) with your externally
accessible IP to get the actual `enode` URL.
*Note: You could also use a full-fledged `geth` node as a bootnode, but it's the less
recommended way.*
#### Starting up your member nodes
With the bootnode operational and externally reachable (you can try
`telnet <ip> <port>` to ensure it's indeed reachable), start every subsequent `geth`
node pointed to the bootnode for peer discovery via the `--bootnodes` flag. It will
probably also be desirable to keep the data directory of your private network separated, so
do also specify a custom `--datadir` flag.
```shell
$ geth --datadir=path/to/custom/data/folder --bootnodes=<bootnode-enode-url-from-above>
```
*Note: Since your network will be completely cut off from the main and test networks, you'll
also need to configure a miner to process transactions and create new blocks for you.*
#### Running a private miner
In a private network setting a single CPU miner instance is more than enough for
practical purposes as it can produce a stable stream of blocks at the correct intervals
without needing heavy resources (consider running on a single thread, no need for multiple
ones either). To start a `geth` instance for mining, run it with all your usual flags, extended
by:
```shell
$ geth <usual-flags> --mine --miner.threads=1 --miner.etherbase=0x0000000000000000000000000000000000000000
```
Which will start mining blocks and transactions on a single CPU thread, crediting all
proceedings to the account specified by `--miner.etherbase`. You can further tune the mining
by changing the default gas limit blocks converge to (`--miner.targetgaslimit`) and the price
transactions are accepted at (`--miner.gasprice`).

// OLD:
// binder is used during the conversion of an ABI definition into Go bindings
// (as part of the execution of BindV2). In contrast to contractBinder, binder
// contains binding-generation-state that is shared between contracts:
//
// a global struct map of structs emitted by all contracts is tracked and expanded.
// Structs generated in the bindings are not prefixed with the contract name
// that uses them (to keep the generated bindings less verbose).
//
// This contrasts to other per-contract state (constructor/method/event/error,
// pack/unpack methods) which are guaranteed to be unique because of their
// association with the uniquely-named owning contract (whether prefixed in the
// generated symbol name, or as a member method on a contract struct).
//
// In addition, binder contains the input alias map. In BindV2, a binder is
// instantiated to produce a set of tmplContractV2 and tmplStruct objects from
// the provided ABI definition. These are used as part of the input to rendering
// the binding template.
// NEW:
// binder is used to translate an ABI definition into a set of data-structures
// that will be used to render the template and produce Go bindings. This can
// be thought of as the "backend" that sanitizes the ABI definition to a format
// that can be directly rendered with minimal complexity in the template.
//
// The input data to the template rendering consists of:
// - the set of all contracts requested for binding, each containing
// methods/events/errors to emit pack/unpack methods for.
// - the set of structures defined by the contracts, and created
// as part of the binding process.
