[experiment] deploy a private ethereum blockchain on kubernetes

tl;dr

• deploy it with your own geth and a customized genesis file and all.

• geth implements Clique, 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

documentation for this work

• genesis block explanation
• deployment on gcp and docker
• deployment of geth in gcp + kubernetex
• running a node in ethereum with geth
• geth creation commands

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.

• interacting with the client:

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

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
