Typos Update proof_of_space.md

[mdqst]

Description:

This pull request fixes several typographical errors and inaccuracies found in the text. Below are the details of the corrections:

1. Typo:

   • Before: "Proof of Space is scheme is necessary."
   • After: "Proof of Space scheme is necessary."
   • The word "is" was redundant.

2. Typo:

   • Before: "is is equivalent to"
   • After: "it is equivalent to"
   • The phrase "is is" was an obvious typographical error, which has been corrected to "it is."

3. Incorrect Term:

   • Before: "Namakoto-consensus"
   • After: "Nakamoto-consensus"
   • This was a mistake in the term. It should refer to "Nakamoto-consensus," a blockchain consensus concept proposed by Satoshi Nakamoto.

4. Typo:

   • Before: "the the pair"
   • After: "the pair"
   • The word "the" was repeated twice.

These corrections aim to improve the clarity and accuracy of the document.
