Episode 44: Blockchain 101: Transaction lifecycle&the mempool - a podcast by Fredrik Harrysson, Anna Rose

In this episode, we are joined by Tomasz Drwięga (https://twitter.com/tomusdrw), 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.
