BitPay Chief Commercial Officer Sanny Singh, has been committed to the application of Bitcoin in global enterprises. Recently, he led a discussion on Bitcoin: blockchain technology for the rapid growth of banks, venture capital, and the importance of businesses and small e-commerce enterprises. }5 5 T.

Preface:
Haven't written a blog for a long time, because they are engaged in bitcoin this thing, now most of the internet is a number of conceptual things, the real content is not much, hear the most words is to center, to the third party, which for the understanding of Bitcoin or block chain technology is not half a dime of the help, So I'm here to sum up the various things about
Strategy analysis of bitcoin high-frequency tradingMany Bitcoin trading platforms implement a zero transaction fee and provide an API interface for trading, providing favourable conditions for high-frequency trading in Bitcoin.How to do bitcoin high frequency trading? A simple trading model is presented below.1, according to their own financial strength, determin
bitcoin production.2. What is bitcoinBitcoin concept is proposed by the Nakamoto, is a point-to-point, de-neuter digital assets, 2009 years in the first block, and won 50 Bitcoin mining incentives, mining awards halved every four years, according to this calculation, Bitcoin is expected to be released in 2140, the total amount of 21 million pieces, With the deve

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
ConceptFollowing the quasi-materialized, flattened (Flat design), long-Shadow, low-poly (Lo Poly), the latest design craze. This style of design has been widely adopted in early computer modelling and dynamic efficiency, and suddenly became popular when it was almost forgotten. The low poly is a retro futuristic style design (which itself can also be called the new aesthetic design of the Neo aesthetic), ba
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
Blockchain Introduction
A blockchain is a data structure that is logically linked from the back to the block that contains the transaction information. It can be stored as flat file, which contains files with no relative relational records, or stored in a simple database. Bitcoin core clients use Google's LEVELDB database to store blockchain metadata. Chunks are sequentially linked from the back to the chain, with each chunk pointing to the previous
Bitcoin packets are very large (more than 10G), and the Bitcoin wallet will default to the packet on the C drive, our C disk space is often not enough, this time, we can move the packet to D disk. Take a look at the method provided by the bit-age gadget.
First step: Find the bitcoin packet to C drive
In the case of Win 7,
The first paragraph: the popular concept analytic POW: Full name proof of Work, work proof. What do you mean by that? That is to say, how much money you get depends on the effective work you're digging for, that is, the better your computer performance, the more mines you'll have to give you, and that's how you perform the distribution of money according to your work certificate. Most virtual currencies, such as Bitcoin, the Wright dollar, and so on,
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
Blockchain, simply put, is like a database ledger, which records all the general ledger of historical transactions and is the underlying technology of Bitcoin. However, because of the deviation of the domestic cognition, the blockchain has not been universally accepted in China, so its application is seldom used. But in Beijing Cornerstone trillion Industry Holdings Co., Ltd. CEO Wang Dong, the entire blockchain industry users gathered a small amount
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

It is understood that Beijing Bar Cafe Bar 2nd place has become the first in the country to accept bitcoin payment bar.
Café Bar 2nd place is located near the five crossing of Beijing, operated by a Japanese company and opened in 2011. The bar, which is close to many universities and a large number of foreigners, has benefited the bar.
In April this year, some Bitcoin enthusiasts gathered at the bar,
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
