Cortex is the first ever blockchain technology that allows the execution of AI algorithms on the blockchain.
In Cortex, due to the nature of open source and competitive mechanisms, the best model as an intelligent agent will survive to enhance the intelligence level of the Blockchain network.
Cortex’s main mission is to provide the state-of-the-art machine-learning models on the blockchain in which users can infer using smart contracts on the Cortex blockchain. One of Cortex’s goals also includes implementing a machine-learning platform that allows users to post tasks on the platform, submit AI DApps (Artificial Intelligence Decentralized Applications).
Problems & Solutions
In the current blockchain world, the chain of built-in Turing Complete smart contracts is widely used, attracting a large number of application developers. However, due to the high cost of over-idealized World Computer concept, smart contracts limit their capabilities at design stage and do not fully exploit Turing Complete immense computational potential. As a result, developers are limited to write short programs and access only a very small amount of resources. While the proliferation of common smart contracts depends on the performance gains of new technologies, some extremely useful routines can be introduced ahead of time and can be applied with reasonable optimization and hardware support. Cortex is a new public blockchain. By revising and extending the instruction set, Cortex adds AI algorithms support for smart contracts so that anyone can add AI to their smart contracts. At the same time, Cortex has proposed an incentive mechanism for collective collaboration that allows anyone to submit and optimize models in Cortex, and the contributors to the models can be rewarded. Just as what’s happening in some areas, thanks to Cortex’s openness and sharing features, Cortex is set to create many models that transcend human capabilities. At the same time, as a social experiment, the team also looks forward to the Artificial General Intelligence (AGI) being born on the Cortex.
Features & Highlights
Smart AI Contract - Cortex allows users to write machine-learning programs on the blockchain and submit interactions that are dependent upon other contracts.
Cortex Virtual Machine - Cortex has its own Virtual Machine, called the Cortex Virtual Machine (CVM). The CVM instruction set is fully EVM compatible and has support for inference instructions.
Cortex Intelligent Inference Framework - Machine learning researchers around the world can upload well-trained corresponding data models to the storage layer. Other users who need this AI models can make inferences by using models and pay to their providers.
Model Submission Framework - Cortex also provides a submission interface for training off-chain, including the instruction-interpreting virtual machine for models. This will setup a bridge between computing power providers and algorithm providers for trading and collaboration.
Cortex Inference Consensus Criteria - When a user initiates a transaction to a contract, the full node needs to execute the code of the smart contract. The difference between Cortex and ordinary smart contracts is that intelligent contracts may involve inference instructions, and then all nodes need to agree on the result of this inferred result.

Token Utility & Use Cases
Rewards for Model Provider - In contrast to the traditional blockchain, in which the reward for each packaging block is paid directly to the miners, to motivate developers to submit richer and better models, Endorphins invoking the contract, are not only allocated to miners who help package the block on full node, but also used to pay the model providers. The proportion of fees charged will be determined by the market gaming price, similar to the Ethereum Gas mechanism. AI smart contracts having higher max Endorphins price have higher priority to be executed. A single execution of a contract will cause a fee of Endorphins Limit * max Endorphins Price.
Cost for Model Provider - To prevent overwhelming model committers from submitting and storing attacks - such as arbitrarily submitting almost unusable models or submitting the same model frequently to consume storage resources - each model submitter must pay for storage. More calls to use the model, more revenue the providers can earn, thereby encouraging the model provider to submit better models.
Model Complexity and Endorphin Spend - Endorphin is a measurement of the amount of computing resources spent on a hardware level within a virtual machine when bringing a data model into a contract during inference. Generally speaking, the cost of Endorphin is proportional to the size of the model. Cortex also sets an upper bound of 8GB on the parameter size of the model, corresponding to up to about 2 billion Float32 parameters.
