How Does Cryptocurrecy Work? Blockchain And Cryptography Explained 

That’s why we’ve created an in-depth guide to all things crypto, from the very blockchain technology it is built on, to the cryptography that protects these assets. 

How Does Cryptocurrency Work? A Detailed Guide To Blockchain And Cryptography

The blockchain acts as a complete record of all transactions made across the network. Before the coin arrives, however, there’s a unique verification process involved called mining.

Mining utilizes computing power to solve complex mathematical equations that unlock a block reward from the protocol and verify each transaction. The block reward is paid in the form of the underlying digital currency, providing an incentive to keep processing power flowing. A miner can also earn cryptocurrency from transaction fees.

Crypto assets themselves feature powerful encryption technology. Each coin has a public key acting as a wallet address and a private key which is used to sign transactions digitally with a unique digital signature.

Here is a more detailed explanation of other important areas of cryptocurrency technology.

Blockchain

Almost every type of cryptocurrency is built on top of distributed ledger technology called blockchain. Blockchain was invented with the debut of Bitcoin, also created by Satoshi Nakmoto, although various precursors exist.

It distributes each cryptocurrency’s ledger across a vast network of nodes. Nodes can act as validators in some types of cryptocurrencies, while others rely on other mechanisms for verification purposes and security analysis.

Because of the wide decentralized distribution, the network is autonomous and fully secure.

Public Ledgers

Another interesting attribute of cryptocurrency technology is that anyone can view transaction information, wallets, and more through a fully public and transparent ledger. Using a blockchain explore, all information is available for all to see.

Thanks to the cryptography involved in crypto, there’s no private information attached to the blockchain, only a series of numbers and letters representing addresses and hash data.

Transactions

Transactions are made from peer-to-peer, to or from anywhere in the world, all without a third party required. Cryptocurrency technology lets users be their own bank, sending cryptocurrency with ease.

Each transaction is added permanently to the blockchain, and cannot be altered in any way. Even if developers decide to launch a new currency instead, the blockchain must be forked, leaving the previous chain intact along with all transaction information. 

Mining

The so called money supply of each virtual currency is created through a process called mining. Unlike gold, it does not require picks, forks, and digging. It does, however, require computation power from powerful machinery called miners, which provide hash rate that keeps the network secure and in operation. 

Proof-of-Work

The process is called proof-of-work and is the cryptocurrency consensus mechanism that many coins are based on, including Bitcoin. 

Proof-of-work prevents an issue called double-spending, which was a major challenge in previous attempts at forms of digital cash.

Adaptive Scaling

Adaptive scaling of certain types of blockchain technologies can be achieved through a proof-of-stake process, sharding, and other scaling techniques. 

Scaling of blockchain throughput increases transaction speed, lowers fees, and increases productivity in the network.

Block Reward

For the efforts and all the processing power that miners give to the Bitcoin network, they receive something called a block reward. Miners also make revenue from fees, however, the real motivation is to get coins.

For example, each block reward in Bitcoin is currently 6.25 BTC. Previously, it was 12.5 BTC and in several years it will be even less.

Halving

Roughly every four years, the Bitcoin protocol as well as some other coins based on its code, will slash the block reward in half. This makes for a seismic shock to the entire ecosystem, that eventually favors price appreciation by throwing off the balance of supply versus demand.

Based on the halving and the low, 21 million BTC supply, the cryptocurrency is projected to become extremely valuable. The halving is a unique factor that causes the asset’s bubble effect, sucking in more participants.

When gold is in a bull market, miners produce more metal to compensate until supply meets demand. In Bitcoin, when demand rises, supply is instead slashed and price rises as a result.

Decentralization

Crypto assets are widely distributed across the globe, and aren’t tied to a government like fiat currencies. This makes them completely dependent on the underlying protocol, but also means full autonomy.

Decentralization enables a variety of benefits for the cryptocurrency and blockchains themselves, due to better censorship resistance, avoidance of 51% attacks, and much more. Peer-to-peer networks have also shown exponential growth according to data, which bodes well for crypto investors.

Wallets

Each cryptocurrency wallet includes a public key which is essentially the public address users must input to send or receive crypto assets. A private key must be stored safely, or the account can be accessed by a hacker, or bad actor. Each public or private key utilizes cryptography and is a string of randomized letters and numbers.

Wallets can be kept offline for cold storage and require USB or bluetooth devices, while hot wallets are directly connected to the web via apps or a desktop computer.

Anonymity

To this very day, no one knows the true identity of Satoshi Nakamoto, the pseudonymous creator of Bitcoin and blockchain. In essence, this person created all of crypto and changed the world of finance forever, yet no one will ever know who exactly it was thanks to the anonymity this person achieved.

Staying true to anonymity, Nakamoto made sure Bitcoin transactions had a layer of pseudo anonymity also. Transactions can be tied to users, but it isn’t easy and requires matching blockchain transactions to bank records and other paper trails.

Cryptography

According to Wikipedia, “cryptography is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. 

Furthermore, it says that “modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.”

Cryptocurrency assets like Bitcoin and Ethereum are also included in that list.

Quantum Computing

One of the biggest fears facing the future of cryptocurrency technology is quantum computing. Ultra powerful computers complete processes at light speed, far faster than current computers. These powerful machines can theoretically crack the cryptography protecting cryptocurrency assets.

This tech is far ways off from being a major problem for the cryptocurrency sector, and new coins are releasing that are quantum resistant.
