Blockchain Fundamentals #1 - what is Blockchain?

Below are some basic understanding of Blockchain.

•  A blockchain is simply a distributed database.
• Think it as a large worldwide computer where everyone can securely access their data and execute transnational code.
• All transactions are stored in blocks of data, these blocks are made in a way that makes them very hard to manipulate or faked once they are stored to the blockchain.
• Due to the nature of the blockchain, you can say that it gives you the trustworthy way to store data in scenarios where there are no trusts. 
• This could be monetary transactions between anonymous strangers on the internet, or the secured way to store your medical data that can only be accessed by those you allow.
• Blockchain is generally not the place to store the large amount of data for each transaction.
• For example you would not store the images on the block chain but you can store the information to validate whether the image is tampered or not.
• Most data stored on blockchain focus on transactions and states of object rather than the actual objects itself.
