Modified Equihash 144,5

ZelCash will swap the POW hashing algorithm from ZCash (200,9) Equihash to ZHash (144,5) Equihash to continue our stance of ASIC-resistance.

Equihash 144,5 is a "stop-gap" for ZelCash. This algo swap will give us time to continue development for ASIC-resistance by exploring more long-term options, such as ProgPOW.

ZelCash Personalization String: "ZelProof"

Zawy LWMA Difficulty Algorithm

The difficulty algorithm will swap from DigiShield v3 to LWMA with the Equihash algo swap. The algorithm was developed for micro/small-cap coins to better adjust difficulty for large hash swings.
  • Faster block find retargeting response
  • Stronger protection against hash and timestamp attacks
  • Reduces number of potential "stolen" blocks

Mining Information

Modified Equihash is similar to the original algorithm in terms of GPU settings. Miners must update mining software and mining scripts. You will see a significantly lower sol rate, this is normal.


Example script: "miner --algo 144_5 --pers ZelProof --server YOURPOOLURL --port XXXX --user YOURADDRESS --pass x --pec"
