In the video titled “Bitcoin, Blockchain, and Cryptoassets: A lecture by Prof. Dr. Fabian Schär,” Prof. Dr. Fabian Schär discusses the fascinating world of Bitcoin mining and the consensus mechanism known as Proof of Work. Schär, along with the team from the Center for Innovative Finance, explores the technical aspects of Bitcoin mining, such as finding hash values below a threshold and adjusting the nonce to create variation. The lecture emphasizes the importance of maintaining a common understanding of the blockchain’s current state and the need for decentralized methods to slow down the block creation process in order to exchange information effectively.

Schär acknowledges that while there are other consensus protocols, Proof of Work, despite its energy consumption concerns, remains the most decentralized and straightforward mechanism for achieving consensus. He assures viewers that in forthcoming videos, they will discuss other consensus protocols like Proof of Stake and Proof of Authority, each with its own pros and cons. Schär highlights the simplicity of Proof of Work and its effectiveness in preventing quick replication of the blockchain, ensuring security and discouraging malicious behavior. To implement proof of work in the Bitcoin protocol, block header hash values are utilized, and these headers consist of various components like the Merkle root and nonce.

Bitcoin Mining and Proof of Work

Bitcoin mining is a fundamental process that underpins the entire Bitcoin network. It involves solving complex mathematical problems to validate and verify transactions on the blockchain. One of the key concepts related to mining is the notion of proof of work.

The Process of Reaching Consensus

Consensus is essential in maintaining the integrity and security of the blockchain. It ensures that all participants in the network agree on the validity of transactions. Achieving consensus in a decentralized and trustless environment like blockchain requires a robust and efficient mechanism.

Proof of Work as the Consensus Mechanism

Proof of work (PoW) is the consensus mechanism employed by Bitcoin and many other cryptocurrencies. It is a method of validating transactions and creating new blocks on the blockchain. PoW requires miners to solve complex mathematical puzzles, which involves expending computational resources.

Expenditure of Resources to Create a Block

To create a block and be rewarded with newly minted Bitcoins, miners need to expend a significant amount of computational power. This expenditure of resources serves as a deterrent to malicious actors attempting to compromise the network. It ensures that participants are invested in the process and discourages fraudulent activities.

Trial and Error in Finding a Valid Hash Value

Finding a valid hash value that meets the specific criteria set by the protocol is no easy task. Miners engage in a process of trial and error, iterating through various hash values until they stumble upon a solution that satisfies the requirements. This iterative process requires computational power and can consume a considerable amount of energy.


In conclusion, this lecture by Prof. Dr. Fabian Schär has provided us with a comprehensive understanding of Bitcoin, blockchain, and cryptoassets. We explored the significance of Bitcoin mining and the proof of work consensus mechanism. By expending computational resources and engaging in trial and error, miners play a crucial role in maintaining the security and integrity of the blockchain. The Center for Innovative Finance and their team strive to continue their research and education efforts to further our understanding of these revolutionary technologies.
