Before Cortex, there was no known way to execute on-chain machine learning models efficiently and deterministically. DApps that include machine learning models had to resort to off-chain inference, which defeats the purpose of smart contracts. Cortex has solved this problem - primarily via the CVM (which utilizes the GPU instead of CPU) and MRT (quantization and integer-only inference). Source: cortexlabs.ai
Mining solo with 100 Gp/s The CTXC network have an estimate of 6429 blocks per day, and a network hashrate of 67.93 KGp/s. With a hashrate of 100 Gp/s, which equals to 0.147% of the network, you will have 946.4% chance of finding a block in a day. On average, you will find 9 blocks every day. at the current network hashrate.
