《精通比特币（第三版）》发布

Author's Source I am very happy to announce that the third edition of Mastering Bitcoin, which was jointly written with me, has now been published with new content. Six years have passed since the publication of Mastering Bitcoin in the previous edition, but the best part of Bitcoin has remained unchanged, but there are also many optimizations that make Bitcoin safer, more extensible and more private. The third edition introduces some of these enhanced signatures, which is a new and powerful way to authorize bitcoin transactions. We provide an easy-to-understand explanation for its working principle, and the inspiration comes from and beyond. The ordinary concise description starts with the initial interactive authentication protocol, and we add details bit by bit, and finally come to the conclusion that the standard scriptless multi-signature realized on Bitcoin today enables almost countless people to create a public key together and spend the money under this public key name only when everyone provides a signature, which greatly improves the scalability and privacy of Bitcoin, making the scriptless multi-signature so simple that we can describe the number in just a few paragraphs. Then we briefly introduce the multi-signature protocol family, which provides additional security against malicious co-signers. Merkel's abstract syntax tree also greatly improves the expansibility and privacy of bitcoin. It allows almost unlimited conditions to be used in bitcoin scripts, and only the conditions that are met need to appear in the chain. Paying to the contract is a method to modify bitcoin public key, which first appeared in 2000 but has not been discussed much. It allows us to use a privacy contract. The promise of receiving funds from Noel can remain mysterious forever, and it can also be publicly proved that it is powerful and simple, so we can quickly explain that it combines the capabilities provided by scriptless multi-signature and integrates into a protocol. Because we have introduced these three basic technologies, it is easy to explain the working principle, the huge improvement it brings to Bitcoin users in scalability, privacy and homogeneity, and the new address introduced by isolated witness and upgrade respectively. The format makes the address easier to use. We rewrote the whole chapter about the address in this book. Now it will start with the earliest address-based payment protocol of Bitcoin, which may also be the origin of the name address. From the address all the way, it will talk about the improvement brought by the handling fee management. In the old edition of this book, there is also a brief explanation, but because of the recent development of the handling fee market of Bitcoin, we have added much more details. We have introduced two methods of handling fees, and we have also introduced the situation that they may be invalid. Easy-to-nail and some recently proposed solutions for contractual protocols, such as transaction packet forwarding and unscripted threshold signature, can be easily explained as a variant of unscripted multi-signature with a verifiable private key partition with an additional feature. This is exactly what another developer and I explained to us privately many years ago when we encountered difficulties in discussions with developers. We once again learned from his inspiration and gave a very understandable explanation. Compact block filter is a kind of light client. Understand the new method that affects their wallet transactions. This method is more private for clients and less troublesome for nodes. We use simple arithmetic and a pair of dice to introduce the principle of dense block filter, which lays a solid foundation for readers before entering the implementation details. Dense blocks not only accelerate the spread of blocks, but also greatly reduce the network bandwidth requirements for running a whole node. We introduce its working principle, and we also introduce the possibility of building on the basis of dense blocks. A block forwarding system that provides faster block forwarding between nodes that trust each other and will not launch denial-of-service attacks and a new method to activate soft forking. We won't introduce many details. I have no idea what method we will use for the next soft forking, but I mentioned the characteristics that this activation method was widely discussed during the year of activation. A new appendix was added after Satoshi Nakamoto introduced the original paper copy of Bitcoin. This appendix was suggested by me. It was the bitcoin theory that I wrote in. A slightly updated version of the corrigendum introduces the difference between the bitcoin described by Satoshi Nakamoto in his paper and the bitcoin actually realized by him and later developers. Who is the new co-author? The main author of this book is almost everyone who knows him. He has given countless speeches, attended hundreds of podcasts, made many videos and written many books about bitcoin. In the past ten years, most of his work has been devoted to guiding people who are first exposed to bitcoin to explain bitcoin to them. How many people have changed their views on Bitcoin because of him, and how many bitcoins have been prevented from being stolen and lost because of his timely suggestions can only be said to be countless. The new co-author is me, and I have been writing technical documents about Bitcoin for nearly ten years, but I am aiming at people who develop and directly use Bitcoin protocols in smaller groups, such as the developer of lightning network and multiple wallet libraries, my most famous identity. As a co-author of the weekly newspaper, my goal has always been to make these developers more productive in the long run, so that the Bitcoin protocol can go anywhere it wants faster. As for this book, we started with the text of the second edition and an outline he set up for the third edition. I revised the outline and added some things that I thought of in the process and things suggested by early reviewers. The final decision of all the texts appearing in the third edition is mine, so any questions are also my responsibility. In addition to updating dozens of pages of new materials, we have also made some substantial improvements to the original part of this book. The old version of this book introduces the language of Bitcoin, but the new features of Bitcoin exist outside the scope. For example, the Merkel evidence of address and script path is inspired by a comment given to me. We show the evolution of authorization and authentication methods of Bitcoin from the version introduced in the white paper to the version realized by software. Script public key and script signature to isolated witness program and witness structure, which not only provides a background for a lot of different features in the current bitcoin input verification, but also shows why bitcoin scripts and programs are not designed for arbitrary calculation. They can be considered as just very flexible public key and signature terms. Satoshi Nakamoto gave us bitcoin, but alas, he did not give us a consistent set of terms. Developers often use terms derived from the function naming of their code, and other developers use different terms. Fortunately, during the writing of this book, a recommendation related to transactions was put forward. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
