After the rapid surge and bursting of the ICO bubble, Bitcoin still sings, breaking the $9600 mark recently. As a digital cryptocurrency independent of the monetary system, the essence of Bitcoin's success is due to technology-blockchain security and privacy that underpin Bitcoin's core value.Referring to blockchain, asymmetric cryptographic algorithms and hashing algorithms are two technical terms that cannot be avoided. In particular, hashing algori

PoW, full name proof of work, that is proof of workload, also known as mining. Most public or virtual currencies, such as Bitcoin and Ethereum, are based on the POW algorithm to implement their consensus mechanism. That is, according to the effective work of mining contribution, to determine the distribution of money.?Bitcoin block?The Bitcoin block consists of t

Recently in the exchange with colleagues in our palletone on the Utxo and signature processing, some experience, write down this blog post. The basic concept of Bitcoin is that bitcoin is a ECDSA digital signature to unlock the unspent balance in Utxo. About Utxo I do not need to do too much introduction, after all, the introduction of the concept of the article has been many. I mainly talk about already ha

Exploring the technology of block chain (I.), constructing the Genesis block of the Bitcoin May one, 2017 0. Understanding block chain technology from a simpler perspective If we use search engine to search block chain, we see most is go to center, distribute, trust, can't change, can't forge, consensus, work proof, POW, equity proof, POS, public chain, private chain, Alliance chain, Intelligent contract, future, etc. a bunch of similar words. Now let

So what exactly is digging mine. How do miners get bitcoin by digging a mine? This requires the POW (work proof) consensus mechanism that is used in the Bitcoin block chain system. PoW (work proof) consensus mechanism Tell a story first: There is a village, and many things in this village need to be made together. For example, one day, the village chief needs all the villagers to make a decision. The villag

Bitcoin encryption algorithms there are two categories: Asymmetric encryption Algorithm (Elliptic curve encryption algorithm) and hashing algorithm (sha256,rimped160 algorithm).Bitcoin private key (private key), public key, public key hash value (Pubkeyhash), Bitcoin addressThe public key and private key are generated by elliptic curve encryption algorithm, the p

In accordance with the relevant policy provisions, domestic Bitcoin trading will be closed by the end of September 2017, but in recent years the historical data on Bitcoin trading may have significant value for future research on economics, finance and quantitative trading strategies, so this article is mainly about how to use Python to deliver from the trading platform API to get the data and save it as a

Recently looked at the bitcoin source code, initially see the mainstream C + + version, but I have not used C + + for many years, almost equivalent to revisit the grammar, in addition to C + + environment compiled a lot of trouble. Instead of starting with the Golang version, the Golang language is relatively easy to get started, and the BTCD version of the code module design and unit testing is clearer and better than the C + + version of the source.

Ching When designing Bitcoin, the capacity of one chunk in the bitcoin is 1M (megabytes). and a sum ofThe deal is 250 bytes or more, and some deals are now roughly 500 bytes.The calculations are as follows: The capacity of a block of bitcoin is 1M, 1m=1 024KB (kilobytes) =1 048 576 bytes, then a block contains the total number of transactions: 1 048 576÷250≈4 19

Reference:http://www.infoq.com/cn/articles/deep-understanding-of-bitcoin-transaction-script In the Bitcoin blockchain, each chunk points to the previous block , and the chunk Hashiki computed by SHA256 is the basis for the non-tampering of the bitcoin ledger. In a block, the Bitcoin system uses trading (Transaction) to

The length of the private key of Bitcoin is 256 bits. In theory, there is a 256 power case. This is a very large number. The number of atoms in the scientific research universe is about 80 power of 10, the second power of 2 is about 77 to the power of 10. Therefore, when a private key is randomly generated, the probability of repetition is quite small, which is also the guarantee of Bitcoin Security. Althou
