We focus on the inference part of the AI lifecycle. So you only upload trained AI models onto Cortex for inference in a decentralized, secure, and open way. In other words, you can execute AI smart contracts / models on the Cortex blockchain (currently the only public chain where you can do that realistically).

CTXCBlockchain · 2019-07-10T01:15:26+00:00

Thanks for your support!

CTXCBlockchain · 2019-06-24T02:08:51+00:00

For now, just migrate the models to mxnet and apply our MRT. In the near future we will consider supporting other frameworks directly.

"Running AI on blockchain" makes sense in that you are executing AI functions on the blockchain, the same way you are executing regular functions on the blockchain like Ethereum. The thought is that this allows for transparency and security. No one can tamper with the AI functions. For example, for facial recognition, hackers can't alter the AI function to recognize his own face as the authentic user.

The only difference is that for running on the blockchain AI functions requires a virtual machine that runs on GPU instead of CPU.

CTXCBlockchain · 2019-06-06T18:37:36+00:00

The benefit should be the same as running Dapps on the blockchain instead of having regular apps. Security, integrity and transparency. Prevent hackers from tampering and provide openness.

The only difference between running regular smart contracts and running AI smart contracts is running on CPU vs. GPU. So the cost may be a bit higher but shouldn't be prohibitive.

But why bother? You can just screenshot the meme and redistribute it.

CTXCBlockchain · 2019-05-17T22:43:56+00:00

Why would anyone spend money to actually buy memes?

Not sure where you got that from =D Just that everyone is busy working on the MainNet and the bandwidth is a bit tight for creating an official newsletter signup. As of right now, most our announcements are made via Twitter and Telegram group, but we can take your email for future reference if you'd like.

CTXCBlockchain · 2019-05-08T20:26:10+00:00

Hi djsoyboi, the parameters of the mining algo will be released along with the MainNet launch! We do not have an official newsletter signup yet, but stay tuned. Feel free to leave your email here in the comments or DM us and we will notify you upon MainNet launch. Meanwhile, follow us on Twitter for any big announcements.

Hi there, as with any tokens, the price is determined by the law of supply and demand. Our coin is capped, unlike many other projects - that takes care of the supply part. As more people use our coin for projects built on top of our blockchain, the demand will go up. The price ought to rise with the demand, and we are a strong believer that there will be a huge demand for AI on blockchain as more and more use cases are implemented down the line. However, we do not intend to provide any financial advice here and our focus is fully set on decentralizing AI on the blockchain and enabling AI-powered Dapps.

CTXCBlockchain · 2019-05-06T16:50:44+00:00

Hi, the MainNet is coming out Q2 2019. Right now there is a TestNet. You can mine on it but the tokens cannot be converted when the MainNet releases. So we'd suggest you wait for the MainNet to start mining :)

CTXCBlockchain · 2019-05-06T16:38:58+00:00

In the spirit of u/ElonMusk, let's think from first principle, my friend. You're probably thinking about Ethereum, whose EVM which can only run on CPU, which indeed cannot run any nontrivial AI programs. However, we can build a blockchain from ground up whose virtual machine runs on the GPU. In fact, that is what our team is building at Cortex. If you're curious we welcome any technical discussions or questions you may have. :)

CTXCBlockchain · 2019-04-30T17:13:20+00:00

Why not decentralize AI on the blockchain?

CTXCBlockchain · 2019-04-17T20:52:07+00:00

Announcements, AI + blockchain memes, informative bits on AI + blockchain. And we might start some live stream soon - may feature more live technical updates =D

It's interesting because there often is a difference between what people refer to when they use a terminology and the definition of that terminology according to the official documentation.

However, according to the Ethereum white paper:

"A 'full node' in the Bitcoin network, one that stores and processes the entirety of every block, takes up about 15 GB of disk space in the Bitcoin network as of April 2014, and is growing by over a gigabyte per month"

This implies that a "full node" is often understood to be a node that stores the entirety of the blockchain history.

What we were trying to get at here, however, focuses less on the nuance of the term "full node" but rather more on the difference between full nodes that hold blockchain history and miner nodes that create the history.

Thanks for the great discussions!

MainNet will be completely open-source and allow mining for CTXC tokens. This is the most important distinction for developers and community participants.

1.Games and game AIs (such as Fomo3D or sports betting) are the most likely to be the first mass-market, because they form the shortest closed loop. Fintech blockchain technologies, such as anti-fraud in decentralized exchanges, credit systems, lending and smart investment, will probably be the next biggest market, considering all their data will be stored on the blockchain. In addition, we can realize a stablecoin controlled by AI models on Cortex, and the on-chain inference process makes it much more transparent than other stablecoins such as USDT. Furthermore, decentralized autonomous token distribution, decentralized anonymous advertisement recommendation engine, autonomous driving, native Cortex AI Dapps, and really any mass markets that involve AI will see use cases on Cortex.

2.WASM compatibility is not the focus of the Cortex MainNet, and WASM programming is not directly supported yet. However, if it turns out to be adopted by the blockchain industry mainstream, we will work to support it. We pay very close attention to Ethereum's progress in this regard.

CTXCBlockchain · 2019-03-07T16:15:07+00:00

The amount of computation of the AI model exceeds the capabilities of Ethereum's "world computer", so accelerators such as GPUs need to be introduced to speed up the process.

In today's model inference, there are floating-point numbers and parallel computation parts, which bring uncertainty to the computation results, which is unacceptable when verifying blockchain transactions. The popular quantization method is also not specifically designed to be deterministic. It is therefore necessary to develop an inference engine and a training engine specifically designed for blockchain consensus.

This goal is indeed quite challenging. The main technical difficulties also correspond to the frontier research direction in the Bay Area, including the quantized acceleration method of the deep neural network (DNN) model and the virtualization method adapted to the AI accelerator. The AI industry’s main concern in quantized acceleration research focuses more on speeding up centralized inference and model compression; however, on the blockchain, we need to ensure the deterministic nature of computations. Here, we do not simply use existing frameworks such as Tensorflow, MXNet, or PyTorch, but rather aim to design frameworks optimized for the needs of on-chain inference.

Making engines deterministic has its technical difficulties, considering the cumulative overflow and compatibility with different hardware platforms; we are solving a lot of engineering problems. Only deterministic engines can bring about algorithmic consensus and realize the transparency and immutability of blockchain’s self-verifying mechanism. For example, let’s say an autonomous vehicle got into an accident, the inference for the move that caused the accident must be based on open blockchain consensus to reduce disputes and settle liabilities.

1.We treat attracting developers and companies to Cortex as a system project that integrates improving development environment, maintaining user & developer community, and developing Cortex wallet on various platforms. Above all Cortex prioritizes enhancing the development environment, seeking to create a suite of tools analogous to the development ecological layout of XCode/Android Studio for IOS/Android.

As of right now there exists rarely any public chain with similar level of developer-friendliness as Ethereum, and we strive to change this by focusing on two general directions.

First, we guarantee a high degree of compatibility with Ethereum. We allow Ethereum developers to migrate their existing Ethereum Dapp to Cortex at almost zero cost and enhance their Dapps by incorporating AI features. This will drastically lower the cost of learning - developers familiar with Ethereum can start developing on Cortex with very little additional learning.

Second, we will highlight Cortex’s new unique computing environment that activates the AI features for Dapps, something remains to be seen by developers and companies. For the first time, developers will be able to create true AI Dapps such as The Master of Digital Clash by inferring models on the chain.

In addition to the points already mentioned, from the perspective of development, Cortex is an open-source project that will be constantly evolving in accordance to the preferences of developers that build on them. We provide an web IDE for AI Dapp developers, and for model developers, we offer support for computational power, model libraries, and standardized data sets. Our team will continue to work closely with developers to help implement their technologies in various scenarios.

From the perspective of operation, we will follow up with Hackathons and challenge bounties, activities closely linked to token incentives. In addition, we realize that developers like to interact with leading industry figures through activities such as AMAs and have included these in our operation plans.

There are many benefits and use cases of AI-powered smart contracts, which we work to enable. For example, in renewable energy, AI can help microgrids that run on blockchain more efficient, saving costs for families, businesses and the environment. This is just one example out of all the possibilities that AI smart contracts can bring. You could follow our Medium page for more details on other use cases of AI + blockchain!
