In an effort to mitigate potential attacks and reduce miner centralization threats, Masari has developed Cryptonight-Fast to serve as our proof of work algorithm. This article will explain why the fork is needed, and highlight necessary preparations.

Reasons for the fork

Within the past 30k blocks, Masari has forked twice. So why another one? The reason is that as a young coin with a relatively low network hashrate, Masari is exposed to a variety of both plain and exotic attacks. Plain attacks could include the rollout of CNv7 ASICs which would drive Masari towards miner centralization through ASIC hashes. Exotic attacks could include the redirection of hashing resources from large pools that offer CNv7; which opens the door for 51% and flash mining attacks.

Both of these attack vectors rely on Masari using CNv7. As such, the most apparent solution to reduce potential corruption within Masari’s network is to use a different algorithm. Cryptonight-Fast is a Masari development that has slight variations from the current CNv7 algo while maintaining Masari’s standard privacy features. CN-Fast will still allow for Masari developments to be pushed upstream and to the greater Cryptonote community.
