A drive(HDD/SSD) failure prediction
Finex drive chain.

This coin was born in Tokyo.
The purpose(main) of this blockchain is to provide a P2P network for drive (HDD / SSD / M.2) failure prediction and to sound data recovery services.
In fact, in Japan, CERTAIN malicious data recovery company have become a social problem.
For example, the following statement has been warned by recovery industry group.
>> click here (in japanese)

e.g. The drive broke and you plan to recover data for about $200.
But fact, what if you are charged 0.7 BTC ...
Do you have any troubles like this in your area?

** About IMPLEMENT drive failure prediction.
* mainchain [COIN transaction] and sidechain [Finex drive chain]

We will implement the prediction feature developed here(>> click) as a "Finex drive chain"
that is utilizes the side chain in cooperation with the Finexbox Exchange and others partner.

About mainchain:
Blockheader size: 80 bytes. (CBlockHeader<uint256>)
Blocksize: 1 MBytes.
Node sync: Full

About sidechain:
Blockheader size: 16400 bytes. (CBlockHeader<uint65536>)
Blocksize: 1 GBytes.
Node sync: Full or header-only

>> around CTxDB: /SorachanCoin-qt/blob/master/src/txdb-leveldb.h
* using CTxDB = CTxDB_impl<uint256>; // mainchain
* using CTxDB_finexDriveChain = CTxDB_impl<uint65536>; // sidechain-1 (under development)

* Later major version 3: implement benchmark.

This feature is benchmark in data preservation. Please be assured.

[SORA] latest wallet released! (Feb,Jan-2021 version 3 !!)

latest version: v3.4.10
We have implemented automatic(dynamic) checkpoints that improve the stability of the blockchain.

v3.3.10: implement sync window.

v3.2.10: implement Peers tab.

https://github.com/FromHDDtoSSD/SorachanCoin-qt/releases

v3.1.10:

We implemented mini window. (option -miniw)
We have realized resident software, lightweight then minimal window.
(e.g. SorachanCoin.exe -server -miniw)

deposit address:
You will get the receiving address and copy the address to the clipboard.
unlock SORA:
Enter your passphrase in the editor below and click "unlock SORA",
exclusively for stake and start staking.
Minimize button:
This window is stored in the task tray.

This method is enough for checking balance, receiving coins, and staking.
Of course, if you remove the -miniw option, you will see usual Qt wallet. Both are built-in.

[SORA] under development

https://github.com/FromHDDtoSSD/SorachanCoin-qt/commits/master

Please try to click the button at the bottom of the wallet.
A independent windows will guide you through a drive solutions.
[SORA wallet Usage: Click here]

If I were a cat, I omit all the troublesome events.
Then, all necessary functions are development policies that are built in to "one executable file --- SorachanCoin.exe , SorachanCoind".
Therefore, "troublesome preparation" to prepare and link various tools and scripts to development utilizing blockchain becomes "unnecessary".

To start development in SORA using the blockchain, just start the executable file.
Simple is the best.

* Roadmap

2018:
We have a idea for realized analyzing failure information to blockchain.

2018-Aug:
launch up Blockchain.

2018-Aug:
We released SorachanCoin Wallet Version 1.0

2019-Aug:
Wallet design brought to new.

2019 - 2022:
We want to listing some exchanges.

2020-Dec:
We will carry out a security-related review.
Windows version wallet: Ver 2.2.9 (Stability-oriented Server version is Ver 1.2.9)
(eg: Improvement of SecureString, QtSecureAllocator and getblockqhash)

2021-Feb(Implemented in Jan 2021):
We will release of "SorachanCoin DriveInfo Wallet" with a benchmark in wallet.

2021-Mar:
We will release "SorachanCoin v4.0 series" equipped with a drive verify feature.

2021-May:
This month is half-life of PoW.
Therefore, we will release "SorachanCoin v5.0 series".
* A "blockchain management window" will be added that allows to connect detailed information about the blockchain with the GUI.
* We will also implement some interesting features such as benchmark rankings.
For the time being, it is a stance to implement.

* About HF (Hard Fork)

We will notify you three months before the HF.
After HF, the blockchain will branch and you will need to switch to the new one.
However, there is no "complex procedure".
We will develop to synchronize only by updating the wallet. Thank you.
