Before we delve into the transformative potential of pairing blockchain and machine learning, it is prudent to start with the fundamentals and gain a clear understanding of what exactly blockchain and machine learning entail.
Blockchain: The Cyber-Sheriff of the Internet Explained
Imagine you have a notebook that you use to keep a record of all the things you buy or sell to your friends. Every time you make a transaction, you write down the details in this notebook. Your friends also have their own notebooks where they do the same thing.
Now, let’s say you want to make sure that nobody can cheat or change what’s written in your notebook. To do that, you decide to share your notebook with all your friends. Whenever you make a new entry in your notebook, your friends also write down the same thing in their notebooks. They check to make sure what you wrote matches what they have in their notebooks.
Once everyone agrees on what’s in the notebooks, that information gets locked, and it can’t be changed. So, if anyone tries to cheat or alter their own notebook, everyone else would notice because their notebooks would still have the correct information.
This is a bit like how a blockchain works. Instead of a physical notebook, it’s a digital ledger (a fancy word for a record-keeping book) that lots of people share and use together. Each time a new transaction (like buying or selling something) happens, it’s added to this digital ledger, and everyone in the network checks to make sure it’s accurate. Once they all agree, it’s like sealing the information in a digital lock, and it can’t be changed.
So, a blockchain is like a super secure, digital record-keeping system that many people use to make sure nobody can cheat when they’re trading or doing transactions online. It helps keep things fair and honest on the internet!
Machine Learning: Barking Up the Right Tree
Imagine you have a clever dog named Max, and you want to teach Max to recognize different types of toys. You start by showing Max a bunch of toys — rubber balls, stuffed animals, and squeaky toys.
Max looks at these toys, sniffs them, and begins to notice differences, like the texture of the toys or the sounds they make. You play with Max using these toys, so he gets familiar with them.
Now, when you introduce a new toy to Max, one he’s never seen before, he can still figure out what it is because he remembers the patterns and differences he learned from the other toys. It’s like having a dog who can tell which toy is which, even if it’s a brand new one.
Machine learning is similar. Instead of teaching a computer, you’re teaching Max, the dog, to recognize things by showing him lots of examples. Max learns to notice patterns and differences, just like a computer does when it learns from examples and gets better at recognizing things over time.
Blockchain & Machine Learning — Mathematical representation
The fundamental mathematical structures used to describe blockchains is a chain of blocks, where each block contains a list of transactions. Here’s a simplified mathematical representation:
Where,
Blocks: Represented as B0, B1, B2, … where B0 is the genesis block and subsequent blocks are linked together in a linear sequence.
Transactions: Represented as T1, T2, T3, … where each Ti represents a transaction included in a block.
Hash Functions: Mathematical functions that transform data into fixed-length alphanumeric strings. These are commonly represented as H(data) or H(Bi) to represent the hash of a block Bi.
Blockchain Structure: Each block contains a reference to the previous block’s hash, forming a chain. This can be represented as B(i) -> H(B(i-1)).
Machine learning can be represented as an equation (a simplified representation) that describes the relationship between data (X), model parameters (θ), and predictions (y). Here’s a simplified equation for a generic machine learning model:
Where,
`y` represents the predicted output.
`X` is the input data, often presented as feature vectors.
`θ` represents the model parameters that are learned during training.
`h` is the hypothesis function that maps input data and parameters to predictions.
Now that we’ve explored the high-level overviews of blockchain and machine learning, let’s delve into how these two technologies work together in a powerful synergy.
