Dx Visionary

Show more...

Dx Leaders have a clear, actionable, and compelling roadmap towards the future. They understand how to document an aspirational and, at times, challenging goal that colleagues and students will strive to meet. A visionary leader does not always need to revolutionize the current state but can take methodical steps to lead an evolution of thinking, content, and pedagogy. A visionary leader understands that there are different motivators that influence stakeholders to commit to an idea and adjust their presentations accordingly.

Steps for independent verification using provided proof data:

  1. Download the hosted assertion from https://factory.cancred.ca/v1/assertion/11c4250fb58de76736a841449461d809ca14e4b1.json

  2. Calculate the SHA256 checksum of the downloaded JSON string.

  3. Verify that targetHash matches the hex-encoded SHA256 checksum.

  4. Verify that the values targetHash, proof, and merkleRoot form a valid Merkle Path.

    Starting with targetHash, traverse the proof list and calculate SHA256 checksums for each pair. Pairs are formed from the value of previous calculation and each list item map value. Argument position of the list item in the hash function is determined by the map key "left" or "right". Final value must match merkleRoot value. Note that all checksums are calculated from hex-decoded binary bytes.

  5. Verify that merkleRoot matches what is stored in the blockchain transactions of the "anchors" list.

    The value to check is stored in the data field of an Ethereum transaction identified by sourceId value. You can use a service like https://etherscan.io to look up the data field using the provided transaction hash.
