Time miner asset chain
mining is the only way to obtain undeveloped bitcoin, which needs to purchase professional mining equipment for mining, which is called mining machine in the instry
bitcoin miner obtains bitcoin through a lot of calculation through hash algorithm. As we all know, the number of bitcoin is constant, 21 million. As time goes on, the number of miners increases and the number of miners decreases.
the difficulty of bitcoin system is dynamically adjusted. Every 2016 bitcoin is g, an adjustment will be made, The adjustment is based on the block time of the previous 2016 blocks. If the average block time of the previous cycle is less than 10 minutes, it will increase the difficulty. If it is more than 10 minutes, it will rece the difficulty. The purpose is to ensure that the system can output a block every 10 minutes, so the difficulty adjustment time is about 2 weeks (2016 * 10 minutes), that is to say, the output will be halved every four years, And the difficulty will be adjusted every 14 days, so the general trend seems that the output of mining will be less and less
2. Purchasing power for bitcoin
after the prevalence of mining, there are some bitcoin mines, that is, multiple mining machines are concentrated in one place for mining, unified maintenance and management, low electricity price, to rece the cost of mining
the most important parameter of bitcoin mining machine is computing power. The higher the computing power is, the higher the output will be. In the difficulty of bitcoin mining, how much bitcoin can be g with 1t computing power is also used to measure the current difficulty of mining. Therefore, some mines will directly sell computing power to users to dig coins. In this way, the mining risk is relatively lower, and there is no need to buy mining machines and equipment, and no need to maintain them, The maintenance and management of mining machine is relatively troublesome for Xiao
3. Reward for bitcoin
with the rising price of bitcoin, bitcoin has gained more popularity than before, and its position in virtual currency is also unmatched by other currencies. There are some real procts of reward bitcoin mechanism in the market, and cat disk is one of them< The simplest way to get bitcoin is to find the person who holds bitcoin to buy bitcoin, which is equivalent to buying goods. But bitcoin is not required by everyone. Therefore, it is necessary to find the person who holds bitcoin and carry out direct transfer transaction. At the same time, there are certain risks, The other side needs indivials to grasp whether they are cheaters or not, so I don't recommend such transactions on the basis of not being acquaintances or not having certain trust
2. Online trading
there are many trading platforms for bitcoin, large or small. At present, the relatively large and well-known trading platforms are Huo coin, coin security, okex, uto market,... And so on. These platforms are more convenient and safe as three-party guarantee transactions, and the only risk is platform running, But the possibility is relatively small, but some small platforms are not without security
IPFs is just an underlying technology, a point-to-point distributed file system
filecoin is the incentive layer based on IPFs and blockchain. Only filecoin has token
at present, filecoin is still in the stage of testing network, and there are many mining machines on the market, so whether we can dig out coins or not needs to be marked with a "question mark". At present, it is the stage of test network, and the configuration of future filecoin miner needs to be studied. You can pay more attention to the test network to help you understand the chain of filecoin

From last year when I entered the field of blockchain and became a member of the coin circle, I found that there are many ways to make money from blockchain. It depends on what you can do to make money
< HR / >first of all, the most direct way is to speculate in digital currency in the exchange . In the initial stage, you can choose some mainstream currencies with high value, such as bitcoin and Ethereum
the fifth way is other special ways . This is another special way, including helping some project parties do community operation, you will get some token, or helping the project parties write white papers, you can also get a certain amount of token reward
there are probably several ways to make money in blockchain. I wish you an early realization of wealth

The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
bitcoin (BTC) is the most popular digital currency in the world. The spread occurred on August 1, 2017. In a "hard fork" event, a new digital currency called bitcoin cash (BCH) was born
e to version switching, bitcoin blockchain is bifurcated into two independent blockchains. Everyone who owns bitcoin before the fork is entitled to the same amount of "bitcoin cash" tokens, similar to a dividend in a stock
bitcoin cash (BCH) is a new version of bitcoin with different configurations launched by a small number of bitcoin developers. It is a new type of blockchain asset. On August 1, 2017, the mining of bitcoin cash will begin, and each bitcoin investor will have the same amount of bitcoin cash (BCH) in his account

currency features
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms

Before the era of blockchain, Nick Saab first proposed the concept of smart contract in 1996: a set of agreements defined in digital form, including agreements on which contract participants can execute these agreements< the basic idea of smart contracts is contracts (special transactions) that can be executed automatically (event driven) and written in code form on the blockchain
since the establishment of Ethereum smart contract, more than 90% of the contracts have been used to issue tokens, and the implementation of relevant business scenarios is still good. What is the future of smart contract? Here you can see the Bytom chain that just released the news and launched the smart contract. As the first public chain project to release AI consensus algorithm in MIT, Bytom, the original chain, released an intelligent contract based on utxo model on the 26th after the main network was successfully launched in April
different from Ethereum smart contract built on account model, Biyuan chain is the first public chain in the whole blockchain instry to build smart contract on utxo model. Biyuan chain also transforms and deepens utxo to support the operation of multiple assets. In addition, compared with the original chain, the smart contract adopts its own equity language, which is a Turing complete and interpretive high-level language. It can easily compare the assets on the original chain for operation, and flexibly integrate into various asset business scenarios
in addition to the release of contract language, more than the original chain has also released multiple contract templates, which are directly attached with clear business meaning. From these contract templates, we can directly see the scene of future commercialization landing, and can extend the imagination in a wider range
currency transaction contract
through this contract, users can trade a variety of assets in Biyuan chain and other people without going through a centralized organization. That is to say, some assets can be locked through the contract. Only when other users enter the specified amount of assets, can they unlock these assets
for example, a decentralized exchange is built on the basis of contract, through which the two parties who want to exchange different assets in different currencies can be matched directly. The transaction speed is fast, and only a very small transaction fee is charged
third party trusteeship contract
under the contract template, users can transfer the specified assets to the third party's account, and the third party decides whether to call the specified account or return to the original account. The third party trust trust trust agreement stipulates that the third party institution can only transfer the assets to the designated account or return to the original account, which prevents the possibility of the third party account from stealing. In the business scenario, it can be expected that an asset custody platform can be built on the basis of the trusteeship contract of the third-party trusteeship institution in the future, which can ensure the custody, transaction and circulation of users' assets through the double trust of the trusted third party and the contract
mortgage contract
that is, the borrower will borrow the assets, and the lender will mortgage the assets into the same contract, and the lender will obtain the borrower's assets. If the lender fails to return the borrower's assets at a certain block height, the borrower will automatically obtain the lender's mortgage assets
call option contract
in this contract, the asset issuer can sell an asset at a certain price, and the buyer can buy the asset at that price. When it exceeds the height of a block, the asset will automatically return to the asset issuer
from the above design of smart contract, we can see some advantages:
firstly, a variety of templates with business meaning provide convenience for the upper layer to build DAPP, and some core business processes can be realized without too much development; Secondly, compared with the original chain, smart contracts issuing assets have templates. Compared with different developers, the security risk under the standard template is much lower. In addition, the contract will be invoked as a sub contract than the original chain when creating the intelligent contract. The contract template changes or errors that will be invoked in the future will not affect all completed intelligent contracts, which is of high security value for the early intelligent contracts. p>
we can understand that using the ratio chain of the extended utxo model butxo to interact with assets as a new form of utxo not only avoids the emergence of data overflow and other vulnerabilities in the Ethereum account model, but also has flexibility, diversity and controllability
for Biyuan chain, the release of smart contract also marks the determination of its core, which will further promote the commercialization of the project
