How does Kaspa use block hashes to prevent miners from manipulating transaction order for profit?
Kaspa's MEV-prevention strategy ties transaction ordering inside a block to the block's own hash, making it nearly impossible for a miner to cherry-pick a favorable order without re-mining the block entirely. In most blockchains, a miner can sequence transactions however they like, which lets them front-run profitable trades or extract value from other users — a practice called MEV (Miner Extractable Value). By making the ordering depend on the block hash itself, any attempt to reshuffle transactions forces the miner to produce a completely new block, burning real computational work. And because mining is a race, another miner would likely claim the valuable transaction first while the manipulator is still grinding through new hashes. For beginners, this matters because it means the ordering of your transactions cannot be quietly gamed by the miner who includes them.
