The network is a distributed hash table or a DHT or runs on a DHT. To discover this DHT and to get the information from it, you need an entry point into the network. And so they serve as that entry point to give you the first sort of entryway into discovering the rest of the network. They don't have any sort of special trust. It's not that you're downloading the blockchain off of these and you trust what they're telling you or anything. So it's pretty much just to speed up this process, right? Because the completely decentralized way would be just to find a peer, a random peer that is connected to the network,. but it might take
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.
