Marco Lee (Ph.D., Kaohsiung University of Science and Technology, graduate thesis researching the application of blockchain. He used to start a business in the information industry, and was fortunate to experience the process from Web1.0 to Web3.0. Love billiards, self-learning and hands-on I actually do it, and I also like to cook for breakfast. Facebook page: Dr. Mark ) "Blockchain" is not a new term, but it is still puzzling and shrouded in mystery. I only started to understand blockchain after studying blockchain.
There are three basic elements in the composition of blockchain, namely decentralization, consensus and currency. Some people may think that as long as photo background removing the blocks are connected to form a chain, it is a blockchain, but the blockchain that I and many blockchain enthusiasts recognize must have the above three elements. So let me start with three elements to illustrate where the decentralized blockchain is hiding. Basic building blocks and concepts "Decentralization" refers to the decentralization of the blockchain, and "consensus" refers to the consensus mechanism adopted in the decentralized state of the blockchain. Anyone can participate, mine and trade in the blockchain without the need for A certain node is specifically trusted.
"Currency" refers to digital assets that are publicly tradable in the blockchain, and whose transaction records are stored on a decentralized ledger. Satoshi Nakamoto published "Bitcoin: A Peer-to-Peer Digital Currency System" in 2008, describing a digital currency called Bitcoin and related algorithms, which proposed an electronic transaction system that does not rely on intermediary trust. Let Bitcoin allow two parties who have not yet established trust in each other to make financial payments without a centralized trusted third-party institution, while providing a transparent and protected data storage mechanism. To put it another way, on the blockchain site, no matter where you are, you must follow a pre-established consensus and use the same digital currency. Although you and I on both sides of the transaction do not
