Flashblocks are 200-millisecond pre-confirmations on Base. Instead of waiting the full two seconds for a block, your app learns that a transaction will be included in about a tenth of that time, then updates the interface before the block is…
Bitcoin Ordinals let you attach data — an image, a line of text, even a small program — to a single satoshi, turning it into a one-of-a-kind artifact that lives on-chain. Bitcoin Runes do something different: they create fungible tokens…
A copy trading bot is a program that watches one wallet and automatically mirrors its trades into your own account. You pick a trader who is good at something, and the bot copies what they do in close to real…
A flash loan lets you borrow money with no collateral, as long as you pay it back inside the same blockchain transaction. If you can’t repay the loan plus a small fee before that transaction ends, the whole thing is…
Solana MEV is the profit validators and specialized traders can capture by controlling the order in which transactions land in a block. Most of it flows through one piece of infrastructure, Jito, and most of it is harmless arbitrage. The…

Reading data from a blockchain sounds simple until you try it. A smart contract emits events, but pulling those events back out in a useful order — filtered, aggregated, ready for a frontend — is slow and awkward if you…
Gzip compression shrinks the JSON that a blockchain endpoint sends back to your application, so large responses download faster and burn less bandwidth. You enable it by telling the endpoint your client accepts gzip — and with most modern tooling,…
A versioned transaction is Solana’s newer transaction format, labeled v0, that can point to on-chain accounts by a short index instead of writing out each full 32-byte address. Address lookup tables (ALTs) are the on-chain accounts that hold those addresses,…
