In this week's episode, Anna and Fredrik dig into the topic of Merkle trees. We discuss the history of the concept, explore different kinds of Merkle trees, and touch on Radix trees & Patricia Merkle tries. We also look a bit at their usage in both Bitcoin and Ethereum.
The topic was a challenging one to explain without diagrams or visuals, so below we are sharing some resources we used in preperation for this episode. We will also be posting this on Github (https://github.com/ZeroKnowledgefm/ZeroKnowledgeBasics/blob/master/MerkleTreeResources.md), please feel free to push additional links that might be relevant.
