About this course Skip About this course. Developed by Blockchain at Berkeley and faculty from UC Berkeley's premier Computer Science department, this course presents Bitcoin and cryptocurrencies as the motivation for blockchain technologies, and provides a comprehensive and in-depth overview of the fundamental concepts of the crypto space with a particular emphasis on Bitcoin. The course covers basic properties of bitcoin, the mechanics behind it e.

You'll learn about practical applications of Bitcoin such as wallets and mining, as well as how to destroy bitcoins, including network attacks and malicious mining strategies. We will also take a brief look at Ethereum and how blockchain can be used outside of cryptocurrencies. This course is open to anyone with any background. Whether you are planning your next career move as a blockchain developer, crypto trader, data analyst, researcher, or consultant, or are just looking for an introduction to the Bitcoin technology. This course will help you to begin developing the critical skills needed to future-proof your career.

Real-world aspects of Bitcoin, such as wallets, wallet mechanics, mining, transactions, and Bitcoin governance and the various ways one can interface with the Bitcoin network. How to destroy Bitcoin, including various network attacks. The properties behind the second largest blockchain platform, Ethereum, including the Ethereum Virtual Machine and the idea of Turing completeness, the key protocol differences between Bitcoin and Ethereum, the use cases of Ethereum.

Syllabus Skip Syllabus. We then build an in-depth understanding of Bitcoin from the ground up, divided into four stages: Identity, Transactions, Record Keeping, and Consensus. We look into the roots of Bitcoin in the Cypherpunk movement and Libertarian ideals, and examine the revolutionary significance of Bitcoin as opposed to some of its early predecessors. We then move onto exploring the history of the crypto space as a whole. Bitcoin In Real Life: Wallets, Mining, and More We examine the most frequently used real world aspects of Bitcoin, such as wallets, wallet mechanics, mining, transactions, and Bitcoin governance.

We explain the various ways one can interface with the Bitcoin network, depending on the specific software they run. We then look into some of the use cases of Ethereum, and conclude with an overview of smart contracts and building decentralized applications. Having spent the last modules primarily on cryptocurrencies, this module encourages students to think about blockchain use cases outside of cryptocurrency. To do that, what would the steps be? First, transaction data is shared with bitcoin users from the memory pool.

The transaction sits in an unmined pool of memory transactions. In a memory pool, unconfirmed transactions wait until they are verified and included in a new block. Bitcoin miners compete to validate the transaction using proof of work. The miner who solves the puzzle first shares the result across the other nodes.

Once the block has been verified, the nonce has been generated, then the nodes will start granting their approval. If maximum nodes grant their approval, the block becomes valid and is added to the blockchain. The miner who has solved the puzzle will also receive a reward of The 10 bitcoins for which the transaction was initiated now will be transferred from Beyonce to Jennifer.

In proof of work, a predefined condition the target is adjusted for every 2, blocks, which is approximately every 14 days. The average time to mine a block is 10 minutes, and to keep the time frame for block generation within 10 minutes, the target keeps adjusting itself. The difficulty of the puzzle changes depending on the time it takes to mine a block.

This is how the difficulty of a block is generated: It is the hash target of the first block divided by the hash target of the current block. This is the difficulty being changed after every 2, blocks, so basically it is very hard to generate the proof of work—but it is very easy for the miners to verify once someone have solved the puzzle. And once the majority of the miners reach a consensus, the block gets validated and added to the blockchain. What if someone tries to hack the data? Each block has solved a puzzle and generated a hash value of its own, which is its identifier.

What is Bitcoin?

Now suppose a person tries to tamper with block B and change the data. The data is aggregated in the block, so if the data of the block changes, then the hash value that is the digital signature of the block will also change. It will therefore corrupt the chain after it—the blocks ahead of block B will all get delinked, because the previous hash value of block C will not remain valid. For a hacker to make the entire blockchain valid for the block B that has been changed, he or she would have to change the hash value of all the blocks ahead of block B.

This would require a huge amount of computing power and is next to impossible. With this method, blockchain is non-hackable and prevents data modification. In the early days of bitcoin, miners used to solve the mathematical puzzles using regular processors—controlling processor units CPUs. It used to take a lot of time for mining Bitcoins and other cryptocurrencies, even though the difficulty levels were easier than today.

As mentioned above, the difficulty level keeps changing and growing, so the miners also had to increase their processing power. They discovered that graphical processing units GPUs proved to be more efficient than regular CPUs, but this also had the drawback of consuming more electricity. A miner has to calculate the return on investment based on the hardware and the cost of electricity and other resources needed to do the mining. Today miners use hardware called ASIC application-specific integrated circuit , which was specifically introduced for mining Bitcoin and other cryptocurrencies.

It consumes less power and has a higher computing power. Miners are profitable when their cost of resources to mine one block is less than the price of the reward. So, Bitcoin miners use their resources hardware and electricity to verify a transaction, and each time a block is mined, new bitcoins are created in the network.

The total supply is limited to 21 million bitcoins; 17 to 18 million bitcoins have already been mined, so only 3 to 4 million are left. As of today, a reward of If individuals buy multiple lottery tickets and pool their tickets together, then this will increase their chances of winning. If someone wins the lottery, then based on the contribution, the reward is distributed among all the participants. The bitcoin mining pool is similar: Multiple nodes share their resources to mine a block.

When a block is solved, the miners split the reward based on the amount of processing power they have invested. The pool members generate a final hash value, then the bitcoin reward gets distributed proportionally among the participants based on the resources they contributed. You can also see an example of a mining pool, in which the participants are sharing their mining resources, and you can see both the unconfirmed reward for which they are mining and what they have earned so far.

A block has four fields, or primary attributes: Previous hash: This attribute stores the value of the hash of the previous block, and that's how the blocks are linked to one another. Data: This is the aggregated set of transactions included in this block—the set of transactions that were mined and validated and included in the block.

Every block is supposed to generate a hash value, and the nonce is the parameter that is used to generate that hash value. The proof of work is the process of transaction verification done in blockchain.
