#### Proof of Work

Tari is mined using a hybrid approach. On average, 60% of block rewards come from [Monero merge-mining],
while 40% come from the [Sha3x][RFC-131] algorithm. Blocks are produced every 2 minutes, on average.

### The block distribution

A 50/50 split in hash rate among algorithms minimises the chance of hash rate attacks. However,
sufficient buy-in is required, especially with regard to merge mining RandomX with Monero. To make it worthwhile for a
Monero pool operator to merge mine Tari, but still guard against hash rate attacks and to be inclusive of independent
Tari supporters and enthusiasts, a 60/40 split is employed in favour of merge mining RandomX with Monero.
A 50/50 split in hash rate among algorithms minimises the chance of hash rate attacks. In Tari, a 50/50 split is employed in favour of merge mining RandomX with Monero and Tari with Sha-3x respectively.

### The difficulty adjustment strategy

The choice of difficulty adjustment algorithm is important. In typical hybrid mining strategies, each algorithm operates
completely independently with a scaled target block time.
