I heard that there has been some progress in cracking SHA-256 hashes, with researchers successfully attacking 31-step SHA-256. Since
Bitcoin uses SHA-256 for its addresses and mining, I'm wondering if Bitcoin is still secure with this hashing algorithm, or if there are plans to change it due to these new findings.

After hashing, the resulting hash is then signed with the sender's private key.
