+# Creating an Ethereum blockchain
+
+To create this blockchaon, we use [geth](https://geth.ethereum.org/), the official client software provided by the Ethereum Foundation written in the Golang.
+
+By default, geth implements [Clique](https://eips.ethereum.org/EIPS/eip-225#:~:text=Clique%20is%20a%20proof%2Dof,any%20client%20with%20minimal%20effort.), a proof-of-authority mechanism to reach consensus. Moreover, a number of accounts a defined to produce new blocks in the chain.
+
+A custom Ethereum testnet contains three components:
+
+* a custom [genesis file](/genesis.json
+* a custom data directory, which we define with `GETH_DATADIR`
+* a custom `NetworkID` , which we set `137`
+
+
+### Gas
+
+Gas refers to the unit that measures the computational effort required to execute specific operations on the Ethereum network.
+
+### Nodes
+
+Running nodes are responsible for the following tasks:
+
+- store blockchain data,
+- participates in block validation (verifying blocks and states),
+- serve the network and provides data on request.
+
+### Storage
+
+More details to be added soon.
+
+### Faucet
+
+More details to be added soon.
+
+---
+
+## Interacting with the client
+
+
+You can run commands directly in the console:
+
+
+##### Getting total coinbase
+
+```
+> web3.fromWei(eth.getBalance(eth.coinbase), "ether")
+```
+
+##### Getting a balance from an account
+
+```
+> web3.fromWei(eth.getBalance("2ee8D80de1c389f1254e94bc44D2d1Bc391eD402"), "ether")
+```
+#### txpool API
+
+Access to several non-standard RPC methods to inspect the contents of the transaction pool containing all the currently pending transactions as well as the ones queued for future processing:
+
+```
+txpool
+```
+
+#### Other useful checks
+
+```
+admin.nodeInfo
+```
+
+
+
+### Setting this chain on MetaMask
+
+Click a `Custom RPC` network and add:
+
+```
+Network Name: "<project name>"
+New RPC URL: localhost
+Chain ID: 137
+```
