How it works
Your document is 'hashed' and then timestamped on a blockchain
WikiTrademarks.io takes your source documents and creates a 'hash' of the file in your browser.
That hash is then uploaded to the blockchain and timestamped.
Your brand name or trademark's proof of existence will be irrefutably stored on a blockchain.
Example - WikiTrademarks
WikiTrademarks is a registered trademark under the USPTO and other international trademark offices
The WikiTrademarks trademark image file can be found as below
The SHA256 hash for WikiTrademarks is: fe60c0df9ee1844bc5f4fd17c278a7ccfbc91b33cd7292a2c7d4153640203a44
WikiTrademarks on Litecoin blockchain: a1ef3f9d7468307588de08da38bbd7c31e98f7910981c5aa40cfffc50b4bf946
In the below screenshot of a litecoin explorer, you can see the OP_RETURN code is fe60c0df9ee1844bc5f4fd17c278a7ccfbc91b33cd7292a2c7d4153640203a44, which shows that our WikiTrademarks image was proven to exist on the blockchain at 22/03/2021, 17:29:39 (UTC+8:00)
What is a cryptographically secure hash?
Why a SHA256 Hash
A cryptographically secure has is created from the contents of your file.
It is virtually impossible for 2 files to share the same hash, which means that you can prove your original document exists by running it through a SHA256 hashing tool and matching it with the hash stored on the blockchain.
We use the SHA256 hash, which is an industry standard. You may read more about SHA256 here: https://en.wikipedia.org/wiki/SHA-2
Which blockchains does WikiTrademarks.io support?
We currently support the following blockchains
Litecoin - A fast and lightweight implementation of Bitcoin.
Creamcoin - A blockchain based on th eSkein chained hashing algorithm, suited to secure 'Proof of Work' operations.
