The Blockcard Protocol: It's the Proof-of-Thought That Counts

Authors: Robert S. Adlemir, Robert S. Adlemir, Chris K. Wong

We identify a major security flaw in modern gift transaction protocol that allows for malicious entities to send questionable metadata to insecure1 recipients. To address these weaknesses we introduce the Blockcard protocol, a novel variant of Blockchain technology that uses an asymmetric proof-of-work CPU cost function over payload metadata to provide a cryptographically secure and efficient method of verifying that gift-givers thought enough about the recipients payload or lack thereof for it to count. This has the advantage of making it computationally infeasible and socially awkward for adversarial gift-givers to double-spend, spoof, or precompute their celebratory thoughts.
