Explore how Bitcoin's blockchain uses four full nodes to store the entire ledger, enabling data persistence and trust through a chain of blocks linked by sha-256 hashes.
Explore how hashes are deterministic, producing a fixed-length signature for each block, ensuring collision resistance and linking blocks to secure the blockchain ledger.
Trace ledgers from ancient accounting to modern money, highlighting transactions, bearer instruments, and the rise of cryptocurrency, while noting blockchain and private keys securing transfers.
Explore how the public witness concept informs blockchain as a digital archive where each node attests to history, follows consensus rules, and fosters incentive-driven persistence and security.
Welcome to Blockchain Foundations course. If you want to find out what blockchains are and the basics of how to use them.
Many people think blockchains are difficult to understand. They may also think that blockchains are just about cryptocurrencies like Bitcoin, Ethereum, but they’re so much more. Anyone can master the basics of blockchains.
They are everywhere. Companies and governments have started to use blockchain technology in earnest and will increasingly do so for the foreseeable future. It is time to take an in-depth look at blockchain technology, and how you can take advantage of its potential.
This course is suitable for you if you are looking to expand your knowledge of blockchain technology but are not a developer or a programmer. It is about software but not written for technical learners. It assumes that you have little to no knowledge of the subject and will explain topics as simply as possible, while not obscuring details that may affect you. The course will give an insight into the critical differences in blockchain software and will provide you with a basic understanding of how and why they work.
After learning this course, you will be able to speak with confidence on the topic, know key differences in technology, and why they are relevant to you, your organization, and your industry. You will also have critical insight into blockchain software’s inherent limitations and shortcomings.
The popularization of blockchain has shrouded the sector into the realm of alchemy. Attaching the words “tokenization” and “blockchain” have spontaneously transformed the mundane into the magical. This course will demystify the topic and cut through the hype. You will understand the changes that are happening and uncover any pretense.
