Blockchain Derived Time Clause Samples

Blockchain Derived Time. Each blockchain (whether it is permissionless or permissioned) has its own different time management and some like Hyperledger Fabric [12], [34] don’t even have such. This poses as an obstacle for using HTLCs as an effective building block for cross blockchain swaps. In particular, in some blockchains it is not possible to make a transaction valid only during a certain time frame, or to derive the time from the blockchain height. Therefore, we ask the following question: We answer the question in the affirmative by intro- ducing a new cryptographic primitive which disposes the need to rely on blockchain derived time in cross chain atomic swaps.
