Ethereum network is just a bunch of computers connected together. Because it's completely decentralized, we don't really have a single server that you can go to and everyone can connect to. We are discovering that network by first connecting to boot nodes, then connecting to other nodes and they also can give you their peers.
In this episode, we are joined by Tomasz Drwięga, a Core Developer at Parity Technologies, to discuss the lifecycle of a transaction on the Ethereum network and how the mempool works.
We will be covering the following topics:
- What a mempool/transaction queue/transaction pool is.
- How a transaction reaches a mempool and what the mempool does with it.
- Looking at what causes the CPU increase and delays in the network.
- What happens when a transaction gets stuck.
- Gossip.
- The security properties of the mempool.
- What a network attack could look like.
