Hello sir/madam,

I'm a newbie in blockchain technology.

I'm in the process of learning the necessary tools in building our project.

We plan on building a decentralized DNS similar to blockstack and a decentralized storage similar to Storj.

These two platform should work together to achieve our goal.

QUESTION:
 
How many blockchain do we need for that two platforms? We are planning to use Bitcoin blockchain for this project.
