"The Ledger of Things" is a revolutionary open source Layer 1 blockchain platform for the tokenization of objects. Current list of the object categories is presented as follows: 3D objects 2D drawings Music Biometrics Radio signals Movements Texts Proof of Scan is a decentralized protocol, which is based on recognition technology. Every object, transformed by 3DPass, obtains its own unique and sustainable identity called HASH ID the object could be recognized by. This will prevent the copying of digital assets and thus open a door for the entire blockchain space to potentially trillions in deals all over the globe. Grid2d is the first 3D shape recognition algorithm, suggested by Michael Co in 2020, which is implemented now as pass3d recognition toolkit. Grid2d is utilized as the hash function for the Proof of Scan protocol. 3DPRC-2 (3Dpass Request for Comments) is a standard p2p protocol for the tokenization of the User objects operating within “The Ledger of Things”, by which the most useful aspect of the "Proof of Scan" consensus is getting uncovered. 3DPRC-2 provides decentralized PoScan API available for customers. The scope of potential 3Dpass applications goes way beyond 3D object recognition and not limited to. Being naturally organized and still cultivating this community driven spirit, 3Dpass is here to encourage developers from all aroud the globe to upgrade the pass3d open source toolkit with new fascinating recognition algorithms and make it even more useful for human civilization. Learn more about the algorithm requirements. Feel free to implement or suggest new algorithm for any category above and jump right in 3DPass contribution rewards program 3DPass Coin (P3D) is a native utility token, operating on The Ledger of Things, which serves to incentivise community members to maintain the network infrastructure. Such aspects as: Storage fee, Gas fee, The object authentication fee, Transaction fee, The validator collaterals, Penalties - are all being counted in P3D.
