The AICHAIN is a public chain that is specially designed as a blockchain infrastructure for AI applications. The AICHAIN inherited the advantages of blockchain technology, such as decentralization, open source, tamper-proof and anonymous, to solve the current challenges of AI such as data domination. However, different from other blockchains that are strictly constrained by data size and programming languages, the AICHAIN used technologies such as plug-in visual machine, out-of-chain storage and API etc. to allow larger data set and different programming languages. Moreover, as the ability to attract applications, users and developers remind the key challenge for all competing AI blockchain platforms, AICHAIN has gained a strong competitive advantage by having reached strategic partnerships with multiple AI applications teams to kick start the ecosystem among data supplier, application developers, platform resource providers and consumers.
