Introducing Proof of Scan: the revolutionary decentralized protocol that not only serves as the consensus mechanism for the 3DPass blockchain network, but also prevents digital assets from being copied. This cutting-edge approach opens the door to trillions of dollars in global deals by tokenizing a wide range of objects, including 3D models, 2D drawings, melodies, voices, and radio signals.
But how does it work? To understand, let's compare Proof of Scan (PoScan) to the more familiar Proof of Work (PoW) used in many cryptocurrencies.
PoScan operates under the rule "One object = One asset" and uses a recognition algorithm known as Grid2d to authenticate 3D objects, unlike traditional hash functions like SHA256 which can only authenticate text or files.
any text or file — > SHA256 — > a hash inherent to the exact text or file

It becomes obvious that using the recognition algorithm allows for authentication of nothing, but the object itself, while the regular SHA256 can only authenticate an exact text line or file. That is the crucial point to understand before moving on.
The mining and block-sealing process also differs from PoW. In PoW, miners compete to find a "nonce" value that, when added to the parent block hash, produces a specific output (ex. SHA256 output, which is below the limit called Difficulty) like this “0000000000000756af69e2ffbdb930261873cd71“
.
In PoScan, miners must guess a unique-shaped 3D object, and the HASH ID of that object is sealed to the parent block hash using SHA256 (learn the details) in a similar to PoW way (Difficulty limit is leveraged). This ensures that only unique and original objects are stored on the blockchain, providing asset copy protection and making the 3DPass blockchain the "Ledger of Unique Things."
Additionally, PoScan provides deterministic finality, giving users the assurance that their tokenized assets will always be safe and secure. This makes it an ideal choice for dApp developers looking to protect and monetize their digital assets.
In conventional PoW (Proof of Work) consensus (ex. Satoshi Nakamoto, which first was applied in Bitcoin), it is allowed for several legitimate chains to grow up simultaneously, and the longest chain wins the competition. Therefore, there’s always a chance for the best chain (the longest one) to be reorganized as a result of miners’ competition. This leads to the potential situation of losing control over the assets stored on the blocks that happened to get in the fork and eventually ended up useless. These situations are out of user control on Bitcoin, Ethereum (PoW), etc.
PoScan is designed to support a number of different recognition algorithms which would be the best fit for the particular industry or business process. Grid2d algorithm was developed as the first one that suits just 3D objects. Expanding pass3d open source recognition library with new algorithms leads to the potential ability of tokenization such objects as: 3D models, 2D drawings, melodies, voices, and radio signals, etc**.**
Leveraging PoScan protocol opens the gateway to endless of potential implementations in decentralized world. In simple words, developers now can tether objects to smart contracts and dApps with one-to-one correspondence and protect digital assets from copying.
Property rights borders are proved by math calculations and always defined by means of recognition parameters set up for each particular asset or group of assets.
3D or 2D art creators could sell their work as copy-protected non-fungible or fungible tokens tethered to art object identity (HASH ID). Music could be sold p2p by pieces, as well (one track = one asset).
Some real objects could be tokenized and turned into backed digital currency, ex. diamonds/carats. Objects could be converted into limited supply users’ assets in different games, VR/AR, Metaverse.
That was a small introduction of Proof of Scan protocol. Stay tuned!
I hope you'll enjoy 3dpass as much as I do and create the best dApps ever!
