Episode 44: Blockchain 101: Transaction lifecycle & the mempool

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.
