Re: [OFFICIAL] █ Bitproof.io █ Say Hello to True Certification in the Blockchain
This project is a rip-off, likely backed by UnSavoryGarnishi. Users should be highly suspicious of the fact that you require registration. That's not unlike regulators desire to taint bitcoin addresses with personally identifying information for the purposes of tax collection and cash flow restrictions. Your justification for the registration is moot considering that the same end can be met with the use of GPG contracts.
The goal of Bitproof is to make Blockchain certification mainstream. People need something easy to use. We only collect email address and full name.
Everything is fully encrypted and works like a brainwallet (your password).
Geeks can use 256 bits keys as password and use our API to send transactions directly to the blockchain (POST /.../ 40BYTES_OF_RAW_DATA).
With the current system, it's possible to serve people who knows nothing about Bitcoin AND geeks.
any difference or development to proof of existence?
Proof of Existence has been created and designed as a proof of concept for bitcoiners. Non-Bitcoin people won't understand anything. More than that, Bitproof offers Proof of Ownership using ECDSA 3072 bits signatures and allow public/private publications (we have our own explorer so you can share your proof after certification).
Let me know if you have any further questions.
Re: [OFFICIAL] █ Bitproof.io █ Say Hello to True Certification in the Blockchain
Is there a reason so that it's better to use OP_RETURN instead of using hash(signature(file.hash)) (or even only signature(file.hash) as passphrase on https://brainwallet.github.io ?
Than the first transaction will be the timestamp.
I'm missing something?

Using a hash as a private key is not as efficient as using OP_RETURN because it will require more transactions. You'll have to send some coins to the derived public key to prove existence of the hash, then you'll eventually want to transfer the coins back (2 transactions = takes more space).
Using a hash as a public key will just "burn" the coins (which is bad - increases deflation).
OP_RETURN has been created for the purpose of storing data in the blockchain, the inputs become fees and are given to the miners (no money is lost).
Re: One of the professional scam I hate the most is : Notary
That's why we created Bitproof
The blockchain will ruin them, with the accountants
... I am lovin'ittm. I will even spit on them when they will be in the severs...
Do you have an idea of a good use case?

https://en.wikipedia.org/wiki/Notary
A notary is a lawyer or person with legal training who is licensed by the government to perform acts in legal affairs, in particular witnessing signatures on documents. The form that the notarial profession takes varies with local legal systems.[1]

Re: [OFFICIAL] Bitproof.io - Say Hello to True Certification in the Blockchain
I can't find any prices mentioned on the site. Is it completely free?
It's currently $0.99/certificate for early adopters.I also can't find any mention of what types of file can be used.
Any type of file, we certify the raw bytes of your files, it has nothing to do with the file type.Lastly, if I certify/own a document, and send it to someone that I later wish I hadn't sent it to, what power of ownership do I have exactly? Can I remotely make the file stop working for them? Or is it basically the same as a notary stamp that proves to them it is still my file.
Certificates are like bitcoins, you cannot reverse a transfer, that's what makes the whole system powerful. In the future, you'll be able to make conditional transfers on Bitproof (based on time for example: let's say this file belongs to XXXX for Y days). Is it a feature you would like to see implemented soon? (If yes, to do what kind of business?)Re: [OFFICIAL] Bitproof.io - Say Hello to True Certification in the Blockchain
Thanks for your comments, we really appreciate getting feedbacks from the community.
At the moment, most of those services only let you do Proof of Existence. Bitproof also provides Proof of Ownership. It means that you will be able to share your file without losing the ownership. Our long term vision is to develop the "Paypal of trust" that will let you make ownership transfers (to begin, you can think about Digital Art, licenses,...). We're also investing a lot in the User Experience, we believe that people should be able to use the power of the blockchain without a PhD.
A lot of people in the Bitcoin community understand that bitcoin (the money) is only one application on top of the Bitcoin blockchain. Even if OP_RETURN (which lets you put data in the blockchain) disappears from the Bitcoin protocol, there will always be other blockchains willing to accept them. We also think huge technical improvements such as Sidechains or Ethereum will fix all those issues.
How does this differ from other notary services that try to use the blockchain for this purpose ?

Not to mention, there is a bias against this type of use (non-financial data in blockchain), how do you plan to combat such criticisms?

[OFFICIAL] █ Bitproof.io █ Say Hello to True Certification in the Blockchain
Bitproof is a decentralized online notary that lets everyone (even your grandma) certify their files in the Blockchain.
What type of certification?
We provide Proof of Existence + Proof of Ownership + Proof of Integrity
Businesses, artists and researchers can protect the integrity of their contracts, put a timestamp on them, prove they are the owner of their creations and prove that the content of a file hasn't changed since the certification.
How do I use Bitproof?
- Drag and drop your file
- Create an account (choose a strong password - this is super important)
- Your file is certified in the Bitproof system (encrypted/hashed/signed client side)
- You can access all your certificates on any devices with your password
Vision
Files can be duplicated millions of times, certificates cannot. We bring uniqueness to files that aren't unique.
Bitcoins have value because they are unique and can't be double spent, certificates bring the concept of value to files in a digital world.
Technical details: for the geek
We put in the blockchain hash(signature(file.hash)).
The proof can be validated with the file's content and the public key. The private key lets you manage the ownership (transfers, issue new certificates...).
We give the signature, the hash and the private/public keys to the user (we also store it on our servers (encrypted with your password client side)).
The signature provides you with Proof of Ownership even if you share the file (hash).
The Proof of Existence is possible thanks to the file's hash and the block's timestamp. However, time isn't always accurate (+- a few minutes) in the Blockchain, that's why we're currently creating an internal transactions tree on top of the Blockchain (also hashed in the Blockchain) with exact timestamps: transactions are ordered, recursively hashed then all put in one hash in the Blockchain every few minutes.
