Official Development documentation

To the question: “How a new node to the network with no past experience can find other nodes?” The answer is there is a list of boot nodes hardcoded in the code. A new nose without any cache will hit these Nodes as entry point, they will share other available nodes addresses. The discovery peer advertisement uses the Kademelia DHT protocol. In 2015 when Ethereum started it had only 3 boot nodes (seems to be still the case, this is the only centralize point is the blockchain).

Energy consumption and environmental footprint

Open discussion: with blockchain layer 1 and layer 2 multiplying, company who want to onboard to blockchain/web3.0 will also have to consider their environmental footprint. For instance, I foresee companies moving a blockchain because the cost in energy will be lesser than another blockchain. On this topic I found the following articles, but please free to add your in comment of this thread.

  1. Ethereum average energy consumption per transaction compared to that of VISA as of October 21, 2021
  2. Bitcoin average energy consumption per transaction compared to that of VISA as of October 21, 2021 (even if Bitcoin does not present any interest on Web3 for now)
  3. Solana’s Energy Use Report: November 2021
  4. Tezos Excels As An Energy-Efficient Blockchain According To New PWC Report
  5. Why the debate about crypto's energy consumption is flawed
