stainless steel jewelry set wholesale philippines The development history of bitcoin

wholesale jewelry stores in los angeles The global financial crisis broke out in 2008. On November 1, the same year, a person who claimed to be Satoshi Nakamoto published a Bitcoin white paper "Bitcoin: A point -to -point electronic cash system" on the P2P website. The new idea of ​​electronic currency -Bitcoin is here. On January 3, 2009, Bitcoin Creation Block was born.
Compared with the legal currency, Bitcoin does not have a concentrated issuer, but is generated by the calculation of the network node. Everyone may participate in the manufacture of Bitcoin, and it can be circulated all over the world. No matter where they are, no matter where they are, anyone can dig, purchase, sell or collect Bitcoin, and foreigners cannot identify user identity information during the transaction.
On January 5, 2009, Bitcoin was not controlled by the central bank and any financial institution. Bitcoin is a digital currency, which is composed of a string of complicated code generated by a computer. The new Bitcoin is manufactured through the preset program.
Whenever Bitcoin enters the vision of the mainstream media, the mainstream media will always ask some mainstream economists to analyze Bitcoin. Earlier, these analysis is always concentrated on whether Bitcoin is a scam. And today's analysis is always concentrated on whether Bitcoin can become the mainstream currency in the future. The focus of the controversy is often concentrated on the contraction characteristics of Bitcoin.
The bitcoin players are attracted by Bitcoin that cannot be issued at will. Contrary to the attitude of Bitcoin players, the attitude of economists to a total of 21 million fixed amounts of Bitcoin is polarized.
The economists in the Kanes School believe that the government should actively regulate the total currency and use the relaxation of monetary policy to refuel or brake the economy in a timely manner. Therefore, they believe that the total currency of Bitcoin has sacrificed regulatability, and what is worse is that it will inevitably lead to deflation and harm the overall economy.
The views of the Austrian school economists are the opposite. They believe that the less the government's intervention in currency, the better, and the total currency fixation is not a big deal, even the sign of social progress.
The Bitcoin network generates new Bitcoin through "mining". The so -called "mining" is essentially using a computer to solve a complex mathematical problem to ensure the consistency of the Bitcoin network distributed bookkeeping system. The Bitcoin network will automatically adjust the difficulty of mathematics, so that the entire network will get a qualified answer every 10 minutes. Subsequently, the Bitcoin Network will generate a certain amount of Bitcoin as a block reward, and the reward will receive the answer.
In 2009, when Bitcoin was born, the block reward was 50 Bitcoin. 10 minutes after birth, the first batch of 50 bitcoin was generated, and the total currency at this time was 50. Bitcoin then increased at a rate of 50 minutes every 10 minutes. When the total amount reaches 10.5 million (50%of 21 million), the block reward is halved by half.
When the total amount reached 15.75 million (new output 5.25 million, that is, 50%of 1050%), the block reward was reduced by half to 12.5. The currency system has only exceeded 10.5 million in 4 years, and the total number will be permanently limited to about 21 million.
Bitcoin is a virtual currency, with a limited number, but it can be used for cash: can be exchanged for currency in most countries. You can use Bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use Bitcoin to buy items in real life.
On February 25, 2014, the Bitcoin opening price of "Bitcoin China" was 3562.41 yuan. As of 4:40 pm, the price had fallen to 3185 yuan, a drop of more than 10%. According to the historical market data of the platform, on January 27, 2014, 1 Bitcoin can be exchanged for RMB 5032. This means that less than a month on the platform, the price of Bitcoin has fallen by 36.7%.
On September 9 of the same year, US e -commerce giant eBay announced that the company's payment processing subsidiary Braintree will begin accepting Bitcoin payment. The company has reached a cooperation with Bitcoin trading platform Coinbase and began to accept this relatively new payment method.
Although the eBay market trading platform and PayPal business do not accept Bitcoin payment, the travel house leasing community Airbnb and car rental service Uber and other brainTree customers will start accepting this virtual currency. BrainTree's main business is to provide enterprises with payment processing software. The company was acquired by EBAY at about $ 800 million in 2013.
On the evening of January 22, 2017, Huobi.com, Bitcoin China and OKCoin Coins successively issued an announcement on their official website that it would further suppress speculation and prevent the price fluctuations. : Starting from 00, the transaction service fee is started. The service fee is charged at a fixed rate of 0.2%of the transaction amount, and the active transaction is consistent with the passive trading rate.
On May 5th, the latest data from OKCoin Coin.com showed that the price of Bitcoin has just refreshed history again, as of the highest level of 9,222 yuan before the release. Starting from 12:00 noon on January 24, China's three major Bitcoin platforms officially began to charge trading fees. On September 4, the central bank and seven ministries and commissions issued an announcement saying that China banned virtual currency transactions. On December 17 of the same year, Bitcoin reached a historical highest price of $ 19850.
On November 25, 2018, Bitcoin fell below the $ 4,000 mark, and then stabilized to more than 3,000 US dollars. On November 19, cryptocurrencies resumed the decline, and Bitcoin visited the $ 5,000 mark since October 2017. The reason was that the previous BCH had a hard fork, and the regulatory authorities strengthened the review of the first token issuance (ICO). Essence
4:30 in the morning on November 21, the quotation of the Coinbase platform Bitcoin fell below $ 4,100, a new low since 13 months.
In April 2019, Bitcoin broke through the 5,000 US dollars again, a new high in the year. On May 12, Bitcoin exceeded $ 7,000 for the first time in the past eight months. On May 14th, according to the offer, Bitcoin Station rose 14.68%within 24 hours.
On June 22, the price of Bitcoin exceeded the $ 10,000 mark. The price of Bitcoin fluctuates at about 10200, and rose nearly 7%in 24 hours. On June 26, the price of Bitcoin exceeded $ 12,000 in one fell swoop, a high point since January 2018. On the morning of June 27, the price of Bitcoin was close to 14,000 US dollars, a new high in the year.
On February 10, 2020, Bitcoin exceeded $ 10,000. According to transaction data, the price increase of Bitcoin exceeded 3%. On March 12, according to the Crypto currency trading platform Bitstamp data, at 19:00

This and acceptance
Bitcoin still has legal or legitimate use. There are many ways to use Bitcoin. Through electronic money exchanges, Bitcoin withdrawal machines, service providers, and individuals, they can be exchanged to local cash or gold coins or buy bitcoin with cash or gold coins; it can also be used directly to use it. Buy items and services, or use Bitcoin financial cards.
Suvenally, after the WikiLeaks announced the acceptance of Bitcoin donations, the individual, organization and enterprise using Bitcoin have grown rapidly.
With the activation of Bitcoin Financial Card, even if the merchant does not accept Bitcoin, it can still be paid at Bitcoin and the real -time exchange rate of Bitcoin and fiat currency. Wait) Consumption, you can still complete the payment according to the instant exchange rate of the foreign currency and the renminbi;
and deducting the deposit account of the RMB to complete the payment, so that the merchants can support mobile payment functions such as VISA or waiting for credit cards or Apple Pay, which can be available. Use;
The use range can be greatly expanded from 10,000 merchants who directly accept Bitcoin to tens of millions of merchants including online shopping, store shopping, restaurants and cafes, take transportation, gas stations, etc. ( Visa 29 million and 32 million), if permitted, can use more than 30 million general fiat currency ATMs around the world, and use Bitcoin to use local cash.
The transaction
The Bitcoin point -to -point network stores all the transaction history in the blockchain. Essence The payer needs to sign a digital signature with his private key to prove ownership and recognize the transaction.
Bitcoin will be recorded on the address of the payee. The transaction does not need to participate in the payment party. The destination destination, that is, income, called "output". If there is input, the input must be greater than equal to the output.
The miners 'output transaction is not input, only output, the transaction record will show the newly generated bitcoin (Newly Generated Coins). In addition to the miners' output transaction, one input must be another output of another transaction, that is, it is also the output of another transaction. An income is bound to be the payment of others.
When one input does not become another transaction output, it is "unprepared", that is, "account balance". After the block of this transaction is broadcast, this transaction has "1 confirmation". The average miner generates a block every 10 minutes, and the birth of each new block will add 1 confirmation of this transaction.
In the number of confirmations reaches 6, the transaction is usually considered safer and difficult to reverse. Bitcoin transactions are irreversible, and each transaction cannot be revoked. Merchants do not have to be lost by fraud -style refusal payment. The only way to get a refund is to ask the other party to do a reverse transaction, but the other party needs the other party’s Cooperate.
Blockchain
Blockchain () is an important concept of Bitcoin. This concept is proposed in the white paper of Satoshi Nakamoto. Blocks (called "block", block).
The newly added data blocks can always be linked to the previous block, that is, the rear of the entire blockchain. Bitcoin point -to -point network stores all transaction history in the "blockchain" (), so the blockchain can be regarded as a ledger recorded by Bitcoin transactions. The blockchain is a group of decentralized client nodes, and a distributed database composed of all participants is a record of all Bitcoin trading history.
Mencong predicts that when the amount of data increases, the user hopes that these materials will not store all the nodes in their own. In order to achieve this goal, he uses the introduction of a latency function mechanism. In this way, the client will automatically eliminate those parts that you can never use, such as the extremely early Bitcoin transaction records.
The Satoshi created the first block of the Bitcoin system, that is, "Creation Block", and a sentence "The Times 03/Jan/2009 on Brink of Second Lout for Banks", and this Sentence is the title of the front page of the Times that day.
The process of confirming a transaction is achieved by solving the workload mechanism of a series of calculation problems.
The workload proof mechanism requires that the computing power of the computer is a certain amount of calculation, which requires a certain amount of time to solve it. The point -to -point network system has a stronger computing power, so that the blockchain can be generated at a faster speed (called "51%attack").
The difficulty of the workload certificate is automatically adjusted by the system, so the average generation of new blocks takes 10 minutes. The nodes of the entire Bitcoin point network will automatically detect the effectiveness of transactions and blocks, and ignore any transactions and blocks that violate the rules, such as those blocks that produce errors, or send the same amount of Bitcoin trading behavior multiple times.
The client participating in the processing block can get a certain amount of newly issued Bitcoin and related transaction fees.
In order to get these new Bitcoin, the user of the user who participated in the processing block needs to pay a lot of time and computing power (for this reason, there are professional mining machines to replace other low network devices such as computers). This process It is very similar to mining mining resources, so Nakamoto Nakamoto named the data processor as "miner" and called the data processing activity "mining".
This new Bitcoin can report to the data processor in the system, and their calculation work provides guarantee for the normal operation of the Bitcoin point network.
In view of this, other similar concepts are used to process the transaction data of the end with the same concept, but it is only adjusted in the workload certificate, such as the use of equity proofs (Proof of Stake) and SCRYPT Algorithm and other
