What is a hash?

[sumbr 78]

maybe, you mean the hash rate, not hash, the hash rate, is the speed required by the miner to mine, so the higher the hash rate, the more results you get, the amount of hash rate is determined by the specifications of a computer,  high specifications of computer, the higher the hash rate, but now people prefer to use Asiic miner, the hash rate is more faster than computer, and the result is more bigger, you will understand about the hash rate if you become a cryptocurrency miner

excellent information to be added to our learning, in the crypto world this term d hash is heard a lot

Your information is very useful, I also want to add that every time you make a transaction in the blockchain, it throws you a unique and unrepeatable Hash, it can be considered as the ID of your transaction. By taking that Hash and searching for it through pages such as Etherescan (which is a blokchain explorer of the ETH network) or Blockchair (for BTC), it will show you all the details of the transaction and you can track your operation

 

 

It is indeed a very useful information @jacksonj, by making our selves aware of the crypto terms we could safe ourselves from mistakes.But I didn't   understand all the post @Wilmer Garcia.Can you give me it's source so that I can go there and read about it in detail.It would be very helpful.By the way it was a great topic although I couldn't understand it but it made me aware of that term about 60 percent.

We can also say that it is a mathematical algorithm that transforms any arbitrary block of data into a new series of characters with a fixed length. Regardless of the length of the input data, the output hash will always be the same length.

When you mine a cryptocurrency, what your hardware does is look for a mathematical solution to a problem, which basically consists of finding a number, then each hash is a possible solution to the problem, the more hash power your hardware can do, the more likely you are. to solve the problem and take the reward, which is the cryptocurrency you are mining.

A hash is a fee that is paid to send money to another wallet, that is, it is like a commission that wallets charge for sending money, it is also used by exchanges to withdraw cryptocurrencies, but clearly it has to be investigated better, to see what the hash is necessarily used

[Gabomg 54]

It is the mathematical function or algorithm that converts a block or chain of information of any size into a different block of fixed size, so that the first information is encrypted. The Hash function is also known as a summary or cryptographic summary function, as it is in charge of cryptographically summarizing a block of information of any size in an alphanumeric sequence, normally smaller,

Thanks for the informative post. I already knew the term "hash" but it seems important to me that they create a post explaining some terms related to cryptocurrencies because they are very useful.

The word hash is used in the world of computing to describe a string of encoded text. A string consisting of fixed-length number and letters and a single, unrepeatable order that represent a series of data. This text string is created by a unique cryptographic function known as a hash function.

 

When we are novices or beginners it is important that we know the terms used in this world of cryptocurrencies is why I have set out to bring them the meanings of those terms so that they can be informed. 
I hope you like it and give it to your heart down here. 

That is my first time that I'm facing word like this because i didn't see this word before that's why I prefer to learn more and more learning is like ocean it can't be complete so the main thing is learning..

[sonic22 106]

The information presented on this topic is excellent, many comments of interest and very complete, congratulations to the members who participated and provided valuable information regarding this topic, it is good to read about these topics and help beginners and not so beginners that is still touring the world of cryptocurrencies, this type of knowledge is needed more to grow every day and thus help this forum of valuable information and you will see.

The encryption function in creating wallet keys is unique so that these letters and numbers are not repeated again forever, and each wallet has an address of specific letters and numbers for this wallet. Bitcoin or other cryptocurrencies are sent via the wallet address, and each cryptocurrency has a different wallet address than the currencies.  The other Bitcoin wallet addresses begin with the number 1 or 3, while Litecoin with the letter M.

In the cryptographic field, hash means a unit of power in terms of mining, the larger the value of this denomination, the greater the result achieved by the mining process and the lower the benefit if this value is scarce, the hash normally It is then used to calculate the mining power of the cryptocurrencies and this aspect is very important for this process

[Shamsiddin 54]

A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. The values are used to index a fixed-size table called a hash table. Use of a hash function to index a hash table is called hashing or scatter storage addressing.

[Yorka 48]

In Mining, the hash rate refers to the amount of computation that miners use to validate the Bitcoin blockchain, and it is the unit of measurement of the processing power of the Bitcoin network. ... When the network reaches a hash rate of 10 TH / s it means that it can do 10 trillion calculations per second and in summary functions they are also called hash functions or digest functions. A hash function H is a function computable through an algorithm such that: It has as input a set of elements, which are usually strings, and converts them into a finite output range, usually fixed-length strings

[justcryptofan 72]

Hash is like a receipt of any transaction you have made on the blockchain in order to track your transactions back to the origins

[Maharba 237]

Your post made me curious and I had to look for more information to be able to understand better and I found this; which I hope will help others, as much as it helped me to understand the concept more clearly, thanks for getting me to think. 

A cryptographic hash function - usually known as "hash" - is a mathematical algorithm that transforms any arbitrary block of data into a new series of characters with a fixed length. Regardless of the length of the input data, the output hash value will always be the same length.

According to an online SHA-1 hash generator, (SHA-1 is one of the most widely used hash functions in computing, along with MD 5 and SHA-2) the hash of my name, Brian, is: 75c450c3f963befb912ee79f0b63e563652780f0. As probably any other Brian can tell you, it is very common for many people to make the mistake of writing "Brain" when they try to write my name. It is so common, in fact, that I once had a driver's license with the name, "Brain Donohue," but that is another story. The SHA-1 hash for "brain," always according to the online SHA-1 hash generator, is: 8b9248a4e0b64bbccf82e7723a3734279bf9bbc4. I will try to comunicate with my wife with hash. lol

Really interesting and very grateful for your explanation, I had handled the term Hash is in the part of mining where a hash refers to the amount of computation that miners use to validate the bitcoin blockchain, when one is mining on a page one generally buys power hash to mine faster.

Hashing is the practice of taking a string or input key, a variable created for storing narrative data, and representing it with a hash value, which is typically determined by an algorithm and constitutes a much shorter string than the original. Hashing is also a method of sorting key values in a database table in an efficient manner.

Thanks for asking and answering the question. I have learned  a new term related to cryptocurrency world. It was a valuable information.

Hello, good afternoon. A hash is the result of a hash function, which is a cryptographic operation that generates unique and unrepeatable identifiers from a given information.

[Maaz sultan 265]

You are right but we are in world of crypto and in this world we thinks that hash is the power of a computer  known as hash rate the more of hash rate have the computer the more it is powerful in the world of crypto we use this terminology in the field of crypto mining for best mining profits we choose mining machines that have high hash rate .

[sukoe 106]

I think the term hash when used in the context of cryptocurrency it may refer to the strength of the computer to mine relative to time in seconds.
