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
Today I would like to share with you some of the strategy of Bitcoin futures. "Market-making strategy" is the most famous one in the strategy, where I want to share some of my experiences with my own thoughts.
Now let's start with the concept.
One, what is to do the city strategy
The market-making strategy (Market-maker strategy) is a risk-neutral (risk-neutral) handicap spreads arbitrage strategy. The basic principle is: between Handicap's selling o
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,
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
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,

See Chao Shin code has this thing, went to check, ORZZLD, the following is reproduced.=============================================================The algorithm is defined in the numeric header file .Assuming that VEC is a vector object of type int, the following code:1 // sum the elements in VEC starting the summation with the value 2 int );Set sum to the element of VEC plus 42.The accumulate has three formal parameters : The first two parameters spe
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
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

IntroductionIn addition to calculating all the elements of a specific range, including successive parts and initial values, you can also use the specified binary operation to calculate the result of an element within a particular range. Its header file is in numeric.The accumulate original function declaration is defined as follows: templateclassclassType> Type accumulate( InputIterator _First,

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
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, someone always asked me: "Jianpeng Ah, we start a business, what do you think of my project?" "In fact, these people's projects ppt do very well, and I do not usually answer the question, because the project can not see anything."
Today, I am here to focus on the answers to your questions:

Two Asian bank websites are blackmailed bitcoin ransomOne of the problems with using virtual money is that when it is robbed from the bank, it may take a lot of work to make it look as thrilling as the movie. So I think filmmakers will have to think about some of the recent dramas like "Chinese Cyber theft robbery".
