Question: Do you want your data immutably stored, safely locked, distributed, for all time?

This service is simple, you don't need an account to be able to write to multiple blockchains such as Bitcoin, Bitcoin Cash and Gulden.

Write your data, any data, to the blockchain of your choice

Your data will be stored immutable and for ever on the blockchain. The Bitcoin blockchain is the obvious choice because it is the most widely distributed blockchain, but you can choose other blockchains.
Select at least one blockchain, but be free to write your data on any blockchain.
The data can be in three formats:
Text
Any file containing readable data
Json
Json is the most efficient form of structured data
Binary data
Files or documents (e.g. .txt | .csv | .docx | .Jpeg)
Hash
Calculate the hash of any file and write this as data
Costs of writing varies per blockchain and moment in time, (look up prices here).Make your choice below!

Once your data is added to the blockchain, you can look it up via any blockchain explorer, or using our Blockchain reader
