Even a slight change in an input string should cause the hash value to change drastically. Even if 1 bit is flipped in the input string, at least half of the bits in the hash value will flip as a result. This is called an avalanche effect.

Since it is computationally infeasible to produce a document that would hash to a given value or find two documents that hash to the same value, a document's hash can serve as a cryptographic equivalent of the document. This makes a one-way hash function a central notion in public-key cryptography. When producing a digital signature for a document, we no longer need to encrypt the entire document with a sender's private key which can be extremely slow.

It is sufficient to encrypt the document's hash value instead. Although a one-way hash function is used mostly for generating digital signatures, it can have other practical applications as well, such as secure password storage, file identification and message authentication code MAC. See Chapter 3 of the User Manual for more information. What you need is a peer-to-peer P2P network. Information sharing in P2P networks is similar to information sharing among friends and family.

If you share information with at least one member of the network, eventually this information will reach every other member of the network. The only difference is that in digital networks this information will not be altered in any way. You have probably heard of BitTorrent, one of the most popular P2P file sharing content delivery systems. Another popular application for P2P sharing is Skype, as well as other chat systems. Hashing Algorithm To understand digital identities, we need to understand how cryptographic hashing works.

Hashing is the process of mapping digital data of any arbitrary size to data of a fixed size. In simpler words, hashing is a process of taking some information that is readable and making something that makes no sense at all. You can compare hashing to getting answers from politicians. Information you provide to them is clear and understandable, while the output they provide looks like random stream of words.

There are a few requirements that a good hashing algorithm needs: Output length of hashing algorithm must be fixed a good value is bytes Even the smallest change in input data must produce significant difference in output Same input will always produce same output There must be no way to reverse the output value to calculate the input Calculating the HASH value should not be compute intensive and should be fast If you take a look at the simple statistics, we will have a limited but huge number of possible HASH values, simply because our HASH length is limited.

If you think Hamlet is just a name or a word, please stop reading now, or read about the Infinite Monkey Theorem. Digital Signature When signing a paper, all you need to do is append your signature to the text of a document. A digital signature is similar: you just need to append your personal data to the document you are signing. If you understand that the hashing algorithm adheres to the rule where even the smallest change in input data must produce significant difference in output, then it is obvious that the HASH value created for the original document will be different from the HASH value created for the document with the appended signature.

A combination of the original document and the HASH value produced for the document with your personal data appended is a digitally signed document. And this is how we get to your virtual identity, which is defined as the data you appended to the document before you created that HASH value. Next, you need to make sure that your signature cannot be copied, and no one can execute any transaction on your behalf. The best way to make sure that your signature is secured, is to keep it yourself, and provide a different method for someone else to validate the signed document.

Again, we can fall back on technology and algorithms that are readily available. What we need to use is public-key cryptography also known as asymmetric cryptography. To make this work, you need to create a private key and a public key. These two keys will be in some kind of mathematical correlation and will depend on each other.

The algorithm that you will use to make these keys will assure that each private key will have a different public key. As their names suggest, a private key is information that you will keep just for yourself, while a public key is information that you will share. If you use your private key your identity and original document as input values for the signing algorithm to create a HASH value, assuming you kept your key secret, you can be sure that no one else can produce the same HASH value for that document.

If anyone needs to validate your signature, he or she will use the original document, the HASH value you produced, and your public key as inputs for the signature verifying algorithm to verify that these values match. Since we do not have a central authority that will validate how much money you have, the system will have to ask you about it every time, and then check if you lied or not. So, your transaction record might contain the following information: I have Topcoins I want to send 10 coins to my pharmacist for the medication you would include your pharmacists public key here I want to give one coin as transaction fee to the system we will come back to this later I want to keep the remaining 89 coins The only thing left to do is digitally sign the transaction record with your private key and transmit the transaction record to your peers in the network.

Your job is done. However, your medication will not be paid for until the whole network agrees that you really did have coins, and therefore could execute this transaction. Only after your transaction is validated will your pharmacist get the funds and send you the medication.

Cryptocurrency Miners: A New Breed of Agent Miners are known to be very hard working people who are, in my opinion, heavily underpaid. In the digital world of cryptocurrency, miners play a very similar role, except in this case, they do the computationally-intensive work instead of digging piles of dirt.

Unlike real miners, some cryptocurrency miners earned a small fortune over the past five years, but many others lost a fortune on this risky endeavour. Miners are the core component of the system and their main purpose is to confirm the validity of each and every transaction requested by users. In order to confirm the validity of your transaction or a combination of several transactions requested by a few other users , miners will do two things.

They will look into the history of your transactions to verify that you actually had coins to begin with.

The validity of each crypto coins is provided by a blockchain. A blockchain is a frequently growing list of records, called blocks, which are linked and secured using cryptography. Now, you might have got the basic idea of what a cryptocurrency is. Cryptocurrencies make use of different algorithms named as hashing algorithms.

Cryptocurrencies algorithms and hash functions are used to secure blockchain transactions and are a necessary component of the crypto mining process. In this Blog, we going to explain in detail about the Top Cryptocurrency Hashing Algorithms and How Developcoins works with Cryptocurrency Development platforms using trendy hashing algorithms. In this article covered by the below topics: What is Hash?

What is Cryptocurrency Hashing Algorithms? What is Mining Hashing Algorithms? What is Blockchain Consensus Algorithms? How Does Hashing Work? A hash is nothing but it is a function that converts an input of letters and numbers into an encrypted output of a fixed length. A hash is created using an algorithm and is important to blockchain management in cryptocurrency. What is a Cryptocurrency Hashing Algorithm? Cryptocurrency algorithm or hashing algorithm — is a mechanism that encrypts virtual currency or digital currency.

Characteristics of Hash Functions For a hash function to be deemed reliable, it should have certain properties. These properties make hash functions fitting for cryptocurrencies. Deterministic The deterministic property of the hash function is that for a particular input, the output should always be the same. Quick Computation Another property is that computations should be quick. Pre-image Resistance Pre-image Resistance means that, from a hash, there is no way that the input can be traced back except for brute force guessing and trying every possible combination.

Randomized The hashes of similar inputs should be vastly different. Else it would be easier to decrypt the hash. Collision Resistance A collision occurs when different inputs have the same output or hash in the case of a hash function. As hash functions are used to validate crypto transactions worth billions, you can imagine why collisions would not be ideal. Hashing in Blockchain Each block in a blockchain represents a transaction.

And each transaction has a corresponding hash. To validate a transaction and gain their reward, miners from all over the world try to brute force a digit hash, less than or equal to the target hash. Brute force, as mentioned earlier requires the guessing and trying of possible outcomes.

But here the possible outcomes could be in the order of trillions. So no human being or ordinary computer could accomplish this. This is why extensive computing power is required for mining. A block in a blockchain consists of a timestamp, transaction data, hash of the block, and the hash of the previous block.
