 The Karlsen Network team believes in decentralization and small-scale
 miners. We will ensure long-term GPU-friendly mining.
 
+### Hashing Function
+
+We initially started with `kHeavyHash` and `blake3` modifications
+on-top. This algorithm is called `KarlsenHashv1`.
+
+`KarlsenHashv1` is currently used in [mainnet](https://github.com/karlsen-network/karlsend/releases/tag/v1.1.0)
+and can be mined using the following miners maintained by the Karlsen
+developers:
+
+* Karlsen [CPU miner](https://github.com/karlsen-network/karlsend) from Golang `karlsend`
+* Karlsen [GPU miner](https://github.com/karlsen-network/karlsen-miner)
+  as reference implementation of `kHeavyHash` with `blake3`.
+
+The following third-party miners are available and have added
+`KarlsenHashv1`:
+
+* [lolMiner](https://github.com/Lolliedieb/lolMiner-releases)
+* [Team Red Miner](https://github.com/todxx/teamredminer)
+* [SRBMiner](https://github.com/doktor83/SRBMiner-Multi)
+* [BzMiner](https://github.com/bzminer/bzminer)
+* [Rigel](https://github.com/rigelminer/rigel)
+* [GMiner](https://github.com/develsoftware/GMinerRelease)
+
+`KarlsenHashv2` will become active via hardfork at DAA score `26.962.009`.
+It is based on [FishHash](https://github.com/iron-fish/fish-hash/blob/main/FishHash.pdf)
+written from scratch in our Rust node implementation. It is FPGA/ASIC
+resistent. It is the worlds first implementation of FishHash in Rust in
+`mainnet` in a 1bps blockchain.
