title: Why SHA-256 used in Bittorrent v2?
body: <p>Since collisions found in SHA-1, BitTorrent moved to more secure hash function SHA-2, but why not to create hash format representation like magnet:?xt=urn:bt_[hash_function_name]:info_hash ?</p>
  <p>Example:
  magnet:?xt=urn:bt_sha3:123456789101112131415</p>
  <p>It's like 2+2 that people will continue building up more advanced computers.
  And collisions can be made in near future, and looking into new protocol, we can already see that its adoption is happening very slowly, it wouldn't be nicest thing if say in 2030 new collision occured, then developers will have to change this protocol again?</p>
  <p>V1 DHT is not compatible with V2 anyway.</p>
  <p>So my noob question goes to @the8472</p>
