Apply what you have learned about cryptography and hashing in previous blockchain to the Merkle Tree, which underlies the process of adding new blocks — representing new transactions — to the blockchain. This course also introduces the concepts of proof of work and proof of stake, which play an important part in ensuring the integrity of the blockchain.

完成時間為 2 小時
Hashing and The Merkle Tree
This first week introduces more technical concepts including how we look at the manner in which data blocks are assembled as well as how hash values and encryption are used to ensure the proper sequencing and integrity of data blocks that are added to a blockchain.

Proof of Work and Proof of Stake I
Now that we have investigated hash functions and hash puzzles, we will focus on proof-of-work, which is an approach to modifying the blockchain that can be difficult and time-consuming to compute. We will also focus on proof-of-stake, an alternative to updating the blockchain in which larger nodes are modified that already represent a large portion of the blockchain. We will investigate the pros and cons of each approach and prepare to apply the principles of proof-of-work and proof-of-stake.
