The basic purpose of blockchain is to keep all the record updated, all its execution, the authentication while the Al will help in making a decision, assessing, and going to help in simplifying the independent interaction.
Putting blockchain and Al aims is to increase the security of systems by placing key aspects of decision-making in the blockchain rather than individual machine learning systems.
The downside for using blockchain is its inherent inefficiency. Blockchain technology is not optimized for speed or compute efficiency. This is actually a feature of the system, not a bug. As such, blockchain systems cant be placed into the execution stream of decision-making without slowing down the process.
Blockchain and Al are two technological trends which have the potential to become even more revolutionary when put together. Both can enhance the capabilities of the other, while also offering opportunities for better oversight and accountability, as well as improving the level of trust, transparency, adoption, and communication.
