Developing bitcoin

1.

According to Beijing time on October 24, Jeff garzik is one of the few key developers of bitcoin's underlying software, so he knows the shortcomings of bitcoin's blockchain at his fingertips. So he decided to create a better digital currency

he named the currency metronome and said it would be the first virtual currency to be used on different blockchains

this mobility means that if a blockchain dies e to developers' infighting or no one is using it, metronome users can transfer their money to other places. Kajik said that would help metronome maintain its valuation and ensure its long-term survival. In order to create metronome, kajik founded the start-up company bloq. Metronome will be officially launched at the money 20 / 20 conference in Las Vegas on Tuesday, he said

metronome will be generated and supported by automatic distributed software, which is neither controlled nor changed by anyone. The software will start auctioning metronome currency in December and will retain and use the proceeds from the auction to drive the price of the currency. The rest of the project will be open source, so anyone can develop applications for metronome

bloq will provide developer tools for enterprise users. Of the 10 million metronome coins to be auctioned in December, bloq and other organizations that help create and promote metronome will keep 2 million of them. Every 24 hours, 2880 new metronome coins are born

metronome avoids problems that users often encounter when they want to transfer from one blockchain to another. That is, users must sell one cryptocurrency they own and then buy another. This creates transaction costs and may lose the potential appreciation of the currency sold. With metronome, none of this is a problem

when users want to transfer metronome to another blockchain, they will get a digital receipt. They can then send the receipt to another blockchain and add metronome to that blockchain

The concept of bitcoin was founded by Nakamoto

On December 12, 2010, when bitcoin graally became a hot topic, he quietly left and disappeared from the Internet

As a descendant of samurai, Nakamoto was born in 1949 in Beppu, Japan. His mother, quanzi, was a Buddhist and brought him up in poverty

When his parents divorced in 1959, Nakamoto's mother remarried and immigrated to California with her three sons. Nakamoto and his stepfather don't get along well, but according to his younger brother Arthur, Nakamoto showed his talent in mathematics and science when he was very young, but also showed his "fickle and strange interest"

Nakamoto graated from Caltech, majoring in physics. Upon graation, he joined Hughes Aircraft and worked in defense and electronic communications. Later, Nakamoto worked for the U.S. military, and his experience was classified as a state secret. Now searching his files, his life is a blank

In 2008, in an e-mail group discussing information encryption on the Internet, he published an article outlining the basic framework of the bitcoin system. In 2009, he established an open source project for the system, officially announcing the birth of bitcoin. On December 12, 2010, when bitcoin graally became the climate, he quietly left and disappeared from the Internet

3. Only Nakamoto himself knows that other people can't get the real answer

bitcoin is the first currency to realize the concept of "secret currency". In 1998, Wei Dai first expounded the concept of "secret currency" in cypherpanks mailing list, that is, a new form of currency that uses cryptography principles to control the issuance and transaction of currency, rather than relying on the central management organization. In 2009, Satoshi Nakamoto published the first bitcoin specification and its proof of concept in the cryptography mailing list. At the end of 2010, Nakamoto left the project and did not disclose much about his identity. Since then, many developers have devoted themselves to bitcoin projects, and the bitcoin community has grown rapidly
Nakamoto's anonymous identity often leads to groundless worries, many of which are related to the misunderstanding of bitcoin's open source features. Bitcoin's protocol and software are published publicly. Any developer around the world can view its code or develop their own modified version of bitcoin software. Just like current developers, Nakamoto's influence is limited to the changes he makes that are adopted by others. Therefore, Nakamoto does not control bitcoin. So, today, the question of the identity of the inventor of bitcoin may be the same as that of the inventor of paper
up to now, bitcoin is only a small-scale large-scale socialization experiment, while Ruitai coin and Qianjin card are the experimental objects of bitcoin.

4. On January 3, 2009, the author of the white paper, Nakamoto Tsung, was located on a small server in Helsinki, Finland. He personally created the first block, the creation block of bitcoin, and won the first 50 bitcoins automatically generated by the system. The first bitcoin came out

bitcoin is a virtual encrypted digital currency in the form of P2P, and point-to-point transmission means a decentralized payment system.

5. Who told you that bitcoin will soon be divided up? Besides, blockchain bitcoin is not a single value function. If you participate in it, you can also save distributed account books. This is not measured by value, and it will make the blockchain era in the future. If you have the strength, I suggest you participate in the proct of the era. Ha ha

Coin circle mining refers to that miners use mining machines, consume electricity, calculate algorithm problems (solve the problem of workload proof mechanism with a certain workload to manage bitcoin Network - confirm transactions and prevent double payment), work out standard answers (obtain the right to generate blocks and successfully generate new blocks), And the process of getting a certain amount of monetary reward (bitcoin)

each person (network node) carries out broadcast transactions to the whole village (Network). After these broadcast transactions are verified by the miners (computers on the network), the miners express their confirmation with their own algorithm answers (work proof results), and the confirmed transactions will be packaged into a data block (one page ledger), Data blocks are strung together to form a continuous chain of data blocks (the whole ledger)

when a person (node) finds the algorithm answer matching the requirements, it can broadcast its results to the whole network. Others can receive the new data block and check whether it is qualified

if other people find that they really meet the requirements (the calculation target required by bitcoin) through calculation, then the page ledger (data block) is valid, and other people will accept it, and correspondingly they will get a certain reward

mining capacity

every time a miner successfully records a page of account book, a certain number of new bitcoin will be born to encourage successful bookkeeping

the bitcoin system determines the number of bitcoins issued according to the preset rhythm of Mr. Nakamoto

in addition to mining rewards, miners will also receive handling charges

since miners can decide whether to package a certain transaction data into a data block, miners may give priority to the transaction with higher handling charge

7. The 21 million bitcoins are artificially set in the source code. One of the parameters can change the upper limit, but most nodes must be changed uniformly, so it is impossible to change them.

8. Digital currency, bitcoin and other encrypted digital currencies are based on distributed network. Now with the deployment of 5g communication technology, distributed network will enter our life and study, and work is inseparable from distributed network! At present, to develop a bitcoin trading system, you can refer to the scheme of Yingtang Zhongchuang, which is based on blockchain technology.
