On the evening of April 2, Zhang Xin, an operator of an Internet company, reported to Odaily, "Just when I opened the graphite document (online collaboration document) and prepared to rush to draft with my team colleagues overnight, it was too weak to log in."
Odaily quickly tried to log in, and it was exactly as Zhang Xin said.
Unable to use it at such a critical moment, Zhang Xin, an old user of graphite documents, decided to activate another similar software. But in theory, whether it is a graphite document or other documents, these centralized servers may stop service (downtime) due to a single point of failure.
Speaking of this, Zhang Xin said: "If there is such a decentralized document, it will not be unable to log in due to a single point problem, and will not store my document on its own server, then how can my creation be Not more free-spirited..."
Odaily searched for products that did not fill this gap. Sure enough, the product managers of the blockchain keenly captured this rigid need and really developedA blockchain-based decentralized note-taking application (DApp) - BCNote.(Note: The BCNote project is also a filing company for the Cyberspace Administration of China)
It is understood that BCNote is based on the mainstream public chain Ethereum / EOS, there is no centralized management organization, and no user information will be stored on the server. Only the private key of personal identity can view the notes, and no one else can access them ( The implication is that if the user forgets the private key, even the notes written by himself cannot be opened).
It also envisions several uses for itself:
For blockchain users, BCNote can be used to save private keys, Keystore, and mnemonic words;
If you are a user who has not been exposed to the blockchain, you can use BCNote to save securities transactions, bank card passwords, and passwords for shopping, games, and social networking.
To sum up, BCNote positions itself as a document safe. "Let you find a solution between the safety of offline backup and the convenience of online backup, we are born for this!"
"It seems that this level of confidentiality is a bit too much for me. But it's okay, the important thing is whether the product works well." Zhang Xin told Odaily.
Zhang Xin opened its Android client, and was created an identity on the chain as soon as it came up.
The main page of this software is simple and easy to understand, so Zhang Xin quickly created a document. Unexpectedly, there is a handling fee (gas fee) for taking notes, which makes Zhang Xin, who is used to free applications, appear "temporarily incapable of accepting".
This is the cost of having the entire network confirm so that no one can tamper with it. Users also need to pay a gas fee to delete their own notes.
Not only is there a fee, BCNote also cannot collaborate with multiple people. Although it solved the pain points of distributed operation and privacy protection, Zhang Xin's basic needs for collaboration and free and easy-to-use were not met. Looking at the unfinished facilities, Zhang Xin finally decided not to work on the chain for the time being.
Finally, I hope that the (future) product managers of the blockchain will go back to make high-availability products after seeing this, and lower the threshold for users to use.
