Is There Anything Done to Prevent Network Splits?

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.
