# Quiz 34

What is the purpose of HASH-160 in BSV?

**Type all answers and select the correct one**

* [x] To generate a BSV address by hashing the compressed x-coordinate of a public key
* [ ] To encrypt transactions
* [ ] To replace SHA-256 in BSV
* [ ] To create private keys<br>

**Note to Learners**

HASH-160 is the BSV specific double hash function of RIPEMD-160(SHA-256). In BSV, HASH-160 is used to: Generate a BSV address by hashing the compressed x coordinate of a public key of an ECDSA public-private key-pair and converting the result to Base58 then Base58Check.
