Why Discreet Log Contracts?

DLCs enables developers to make bitcoin payments based on an oracle's signature. This can be used to construct forwards, options and contracts for difference that are settled in bitcoin with minimized counterparty trust.

Customized derivatives

Custom payout curve based on oracle’s outcome

Trust Minimized Derivatives

No single user of a DLC controls access to the bitcoin while awaiting settlement


The oracle is has no way to prove you used them for settlement


Refund mechanisms are built into every Discreet Log Contract
