Every Contract You Use Stores Your Data 🔍 People talk about transaction privacy and forget the contract itself is keeping records on them. $ADA settles contracts through an eUTXO model where the datum attached to each output is readable by anyone running a node. That datum holds whatever the protocol needed to know about a user, permanently, for anyone who looks. Shielding on $ZEC never reaches this, because the design protects transactions and Zcash carries no contract state to protect. So sealing the payment while the application keeps the file is half a solution. Midnight runs the contract itself over hidden inputs, using Kachina, the protocol underneath that lets a contract hold state nobody else can read. That contract gets checked by a validator who confirms it executed correctly and never learns what it executed on. That is the difference between a chain where privacy is a transaction type and one where it is how applications get written. Compact gives a developer that switch per input, so an app keeps an identity document sealed while proving the single attribute it needs. A protocol built that way never accumulates the database it would later have to defend. None of that is theoretical, because most of the damage in a breach comes from records a service chose to keep long after it needed them. Those records are piling up in contract state right now, on every chain treating privacy as a transaction type. I think that is where the next leaks come from, because everyone hardened the payment layer and left the application database wide open. #Privacy #Macro Insights#
