This is why I despise “where’s Waldo” and “colored balls for a color-blind person” analogies for ZK. I’m not aware of any real shortcut to providing a correct intuition for what ZK actually does under the hood.

Which DeFi project has the best order-book DEX? I mean actual order book, not AMM.

English is a very funny metaskill. By itself, it pays horribly but when combined with something else, it suddenly has a 10x outcome.

An immutable variable in solidity can be indexed bytewise. For example: ``` uint256 immutable x; // … bytes1 y = x[0]; ``` You can simulate immutable strings (up to 32 bytes) this way.

Check if a number is even or odd in Solidity: Don’t do `n % 2 == 0` Do `n & uint256(1) == 0` If the final bit is zero, then the number is even. The second method is cheaper.

Yesterday we launched an Ethereum to Solana course. Unlike other courses, this assumes you already know Solidity and Ethereum development at the intermediate level. We help you reuse knowledge rather than start over. Check it out RareSkills.io/solana-tutorial This was made possible by a grant from @solanafoundation

Throwback to my first article series on Solidity / Web3: how to save gas on NFT mints: Over 2 years old but still very relevant, and has inspired dozens of similar articles since. https://medium.com/donkeverse/hardcore-gas-savings-in-nft-minting-part-1-16c66a88c56a?sk=da05a13b9dafb07f0103c65ed45440ca
