The Big Challenge: Reading Blockchains Efficiently and Trustlessly Imagine the blockchain as a giant, ever-growing public library filled with billions of books (blocks) recording every tiny action. You want to know: "Did Alice add liquidity to the Uniswap decentralized exchange in Block #12345?" How would you normally find this out? Download the entire library yourself: You could run a "full node," which means downloading and keeping a copy of every single "book" (all transaction data) in the blockchain. This requires a lot of storage and powerful computers. It's truly "don't trust, verify," but it's very expensive and resource-intensive for most people.
