HDD/SSD/NVMe scan and failure prediction. Web3.0/NFT features, crypto memo. then, quantum resistance.

Welcome to SorachanCoin [SORA Network]

We are developing new features, Web3.0/NFT and so on.

About public key in SORA Network (SORA and SmartContract)

Web3.0: Proof of work / Proof of stake Hybrid system
NFT: Smart Contract (qToken send/recv)

Max supply: 8,000,000 coins
Proof of work reward: 1 coin + fee, per block
Proof of stake reward: 3%, per year
Proof of work algo: Scrypt
Block generate time: about 3 mimitus (1 day supply: about 400 coins [PoW/PoS])
Crypto Key: secp256k1 (SORA), quantum resistance (SmartContract qToken)

crypto memo via Blockchain.
* Encrypted memo is written to Blockchain(SORA Network).
* Of cource, the memo only read/write ... only myself.

“crypto memo” is a simple configuration with only “Write” and “Rescan”, simple is best.

“Write” encrypts the memo with its secret key (HD Wallet) and writes it to the blockchain.
Since only you have the secret key, you can never see it other than myself.

If this is SSL, the connection process is encrypted with the public key, but since the server that executes the SSL has the secret key, the company that manages the server will take all the data with raw(decrypted).
That is a big difference from the Blockchain.

“Rescan” restores HD Wallet from 16 phrases in other places, just click on it and the memos deposited on the blockchain will be returned as they are.
In other words, as long as you memorize 16 phrases, you don't need a backup, hardware wallet, paper wallet, etc.

[Web3.0/NFT via Blockchain part2]
Only using 16 passphrase, restore wallet completely.

Do you get a backup a wallet? or hardware wallet? then ... paper wallet?
No need, those backup, hardware wallet, paper wallet, and so on.

About SSD/NVMe scanning [Catch Ghost-like bad sectors ... i-sector]

We will use Blockchain and statistics to determine the scan of SSD/NVMe with "uncertain sectors" when a failure approaches. "Uncertain sectors" will be placed as "i-sector", and will wait until they are confirmed.

From there, we will utilize the knowledge of blockchain.
Below, FromHDDtoSSD v3.0(Build:5380) SSD/NVMe statistics scan with Blockchain.

FromHDDtoSSD also comes with all the basic features of the wallet, therefore you can operate everything just here. The network fee for this scan is approximately 0.02 - 0.04 SORA, Fee will be assigned to the miners reward in the next block.

statistical scan [with i-sector] to SSD/NVMe (via SORA Network)

Are you scanning a drive?
Recently, SSD/NVMe has joined as a new factor in addition to HDD.
But ... SSD/NVMe inspection is very complicated.

SSD/NVMe "states fluctuate" compared to HDD that can be simply checked for sector reading, so such inspections do not give accurate values. Therefore, we pursued SSD/NVMe inspection by processing the probability distribution using the Blockchain.

From now on, SSD/NVMe will also have a huge capacity. Inspection is so important.

About HDD scanning

There is no problem if HDD in the conventional inspection (only checking if a sectors read-able).
Because, it can always be processed with a converging constant.

Due to this property, it matches the result using SORA Network. in other words, we don't need SORA Network for HDD. But ... is that true?

The following theorem is helpful in this regard check.
* Identify theorem

fullscan to HDD (only checking if a sectors read-able)

[Web3.0/NFT via Blockchain part1]
Let's phase the scan results. full-scan and stat-scan.

A, fullscan to SSD/NVMe [only checking if a sectors read-able]

B, Equalize this result(A) to a statistical scan [with i-sector].
The analysis result below graph is significantly reduced. This indicates, that the inspection accuracy is low with only checking if a sectors read-able. This phenomenon denotes the cause of the accident that the data was lost immediately despite being inspected.

C, statistical scan to SSD/NVMe [with i-sector]
Using statistical scan, the scanning accuracy is improved and it turns out that this drive is no problem.

D, fullscan to HDD [only checking if a sectors read-able]

E, Equalize this result to a statistical scan [with i-sector].
The analysis results in the graph below show normality.
In the case of HDD, it shows that the results of fullscan and statistical match. Because, fullscan is enough if the case of HDD. The proof is the identity theorem.
