Algorithms for cryptocurrencies

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. Some algorithms can be used in multiple cryptocurrencies because the number of cryptocurrencies today exceeds the number of existing algorithms. Miners decrypt this algorithm seek hash. 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 need for digital privacy and security increases as the world becomes more digital. Creating that is complicated because the world is transforming into a digital world at an alarming rate. As mentioned, we humans like to automate and simplify things as much as we can. Algorithms, in a cryptographic sense, are often classified into one of three categories; encryption, signature, and hashing. Each of these categories is equally valuable.

Essentially, each of them is a crucial link in a chain leading towards strong encryption. In the end, leaving any of them out does a grave injustice to the process. Encryption Algorithms We use encryption algorithms to encrypt data and provide confidentiality. Basically, encryption involves converting information or data into a cipher or code.

The purpose is to prevent unauthorized access. Additionally, encryption enables us to conceal data by converting it into a code. Unauthorized viewers are unable to understand the data. Therefore, encryption algorithms must include algorithms that work both ways. We need a powerful algorithm to encode the information to the level we need. To be sure, we need an equally powerful algorithm to decode that information. When we sign something, we mark it to identify oneselves as the writer or sender.

Likewise, digital signatures serve the same function when it comes to data. The signature is another important requirement to consider a digital currency a cryptocurrency. Specialized algorithms make is possible to create a one-of-a-kind signature in digital form. Fundamentally, digital signatures provide enhanced authentication when sending and receiving digital messages.

Authentication is a process. Through it, we prove or show something to be true, genuine, or valid. Signature algorithms work on both the sending and the receiving end. They create genuine signatures on the sending side. On the other hand, they also ensure that signatures are valid on the receiving side.

Hashing Algorithms We use hashing algorithms to provide data integrity. To hash something literally means to chop it up. Hashing algorithms allow us to condense large pieces of information into shorter forms. On the other hand, integrity means that something is whole and undivided.

When data has integrity, it is both complete and sound. Complete data means that it has all of its necessary parts or elements. In terms of soundness, it is free from error, fallacy, or misapprehension. In short, hashing algorithms allow us to condense data while maintaining integrity.

As with other types categories of algorithms in this post, each function creates a requirement for its opposite. This is like trying to find a grain of sand in the Sahara Desert. Virtually any kind of data can be hashed, no matter the size or type.

Hashes have been designed to act as a one-way function. What this means is that you can put in data into the hashing algorithm and get a unique set of symbols, but you cannot determine the original message from the result. Changing the input number will change the hashing value. A unique set of input data will always produce the same hash. In the context of blockchain and cryptocurrencies, each transaction is taken as an input value and run through a hashing algorithm such as SHA, Scrypt, MD5 that produces an output of fixed length.

How Does It Work? However, it is challenging to reverse. While encryption can be reversed or decrypted using a specific key, hashing is one way. Bonus Tip: You may have been involved in hashing without even knowing. There is every possibility that you have an email account or a social media account on Facebook or Twitter. Now for every time you need to log in, you have to input your password. What if I told you that most platforms do not save your password as it is. Instead, they run your password through a hashing algorithm and save the output hash of your password.

So, for every time you try to log in, the platform runs your password through their hashing algorithm and then compares the output with what they already have saved in their database. You are granted access only when both hashes match.

It is used to write new transactions, their timestamp, and add a reference to them in the previous block. A combination of several blocks is what is then known as the blockchain. When a new block of transactions is added to the chain, a consensus has to be reached among the operators of several nodes. These nodes validate and verify that the transactions are right and true. It is almost impossible to reverse a transfer once the nodes in a network confirm it is true.

Trying to do so requires enormous computing power, and this will alter the one-way nature of hashing. Cryptocurrency Hashing Algorithms Cryptocurrencies make use of different algorithms, otherwise known as hashing functions. We have already explained that a hash is a message digest. If you have ever done some essential reading on Bitcoin or ever tried to mine it before, you may have come across this term. With regards to Bitcoin, this algorithm is used during the creation of a public key from a private key.

It is also used during the realization of the process of proof of work. It belongs to the SHA-2 family and a bit 32 bytes signature is generated for a text string. It is worth noting that hashing algorithms are not specific to only cryptocurrencies. As with Bitcoin, there have been attempts to decentralize payment systems in the past.

Bitcoin is only famous because it was the first successful attempt at this concept. Similarly, a hashing algorithm is not a new concept and is being applied in several other industries. So, your understanding of algorithms concerning cryptos from this guide , is universal and can be applied to other fields. During the early days of Bitcoin, miners could validate transactions and mine Bitcoins using regular CPUs computer processing units.

However, they soon discovered that GPUs graphics processing units could do a better job. Presently, none of the above options can generate a substantial amount of Bitcoin. The block processing time for this algorithm is around ten minutes. Some other cryptocurrencies other than Bitcoin that used this algorithm include Bytecoin, Devcoin, Joulecoin, Battlecoin, Peercoin, and Betacoin, amongst others.
