The v3 update switches cryptographic algorithms and brings other improvements:
- Cryptographic hash switched from SHA-1 to SHA-3.
- Digital signature switched from RSA-1024 to Ed25519.
- Key exchange switched from Diffie–Hellman to Elliptic-curve Diffie–Hellman.
Address length changed from 16 characters to 56 characters.
For example, zwdpzg2tzsqjinlb.onion

Blacknet will start migration in version 0.3.
