at present, bitcoin mining needs professional ASIC miner. If you are just playing, you can buy a 500 or so Avalon 2 miner to experience it. A big cost of bitcoin mining is electricity, and the price of mining machines
if you want to be a miner in the mining instry, you need more professional Avalon third generation miner. It's better to deploy large-scale mines for mining, with higher scale efficiency. Of course, the ant S3 is a good choice, but the energy consumption of S3 is low, but the price is high. Although Avalon III consumes high energy, it has low price and cost advantage.
as of April 18, 2020, the price of Leyte is about 305 yuan
litecoin (LTC) is an improved version of digital currency inspired by bitcoin (BTC). It was designed and implemented by a programmer who once worked in Google. It was released on November 9, 2011. Lightcoin and bitcoin have the same implementation principle in technology, but the creation and transfer of lightcoin is based on an open source encryption protocol, which is not managed by any central organization
lightcoin is a kind of network currency based on "peer-to-peer" technology, and it is also an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world. Lightcoin was designed and implemented by a former Google programmer (Li Qiwei). It was released on January 9, 2011
lightcoin is an improved digital currency inspired by bitcoin. The technical principle of lightcoin is the same as that of bitcoin. It also adopts a decentralized architecture, without any central organization control, and the new currency issuance and transaction payment transfer are based on open source encryption algorithm. All these are imitations of the design principle of bitcoin
however, lightcoin tries to improve the shortcomings that bitcoin has shown before, such as slow transaction confirmation, less total upper limit, workload proof mechanism leading to the emergence of large ore pool and so on. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences
first, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network
thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte is divided into 100000000 smaller units, defined by eight decimal places

bill is a kind of valuable voucher, which needs a hidden "third party" role to ensure the safety and reliability of both parties in the transaction. However, with the help of blockchain, there is no need for a third party to supervise and verify the information transmitted by the two parties, nor for a specific physical object to be used as a proof to connect the two parties to obtain trust, thus realizing the "invisible" transmission of value between point-to-point
in the development of bill platform based on blockchain, Yingtang Zhongchuang said that the application of blockchain technology in the development of bill platform has the following functions: to realize the disintermediation of bill value transmission; Effectively prevent the risk of bill market; Change the existing system structure of electronic commercial draft; Improve operation efficiency; Standardize the market order and rece the cost of supervision
the advantages of the blockchain bill platform are as follows: the system construction and data storage do not need a central server, nor do they need a central level application; The integrity, transparency and verifiability of data can be traced and queried for any value exchange; The form of smart contract makes the bill programmable and controllable in the whole life cycle.
