Different Facets Of The Blockchain Technology

Introduction

We have seen many topics related to blockchain explaining different facets of the technology. This article is an attempt to put together the main aspects of the technology and how it has shaped up so far from the invention of bitcoin as the first application of blockchain technology.

πŸ”— Cryptocurrencies

The blockchain journey starts with cryptocurrencies. The blockchain technology journey started with the bitcoin platform. The coin is the first cryptocurrency ever, and it changed the course of the finance industry for good. Cryptocurrencies include the properties of cryptography, which result in the property of immutability.

Peer-to-peer networks lead to decentralization, which has become the need of the hour with ever-growing frauds. The cryptocurrency platforms use different consensus algorithms like Proof of Work, Proof of Stake, Delegated Proof of Stake, Proof of Burn, etc., which overcome Byzantine Fault Tolerance issues. People who maintain the network and confirm the transactions are incentivized using the local currency of the platform.

πŸ”— Cryptocurrencies with enhanced privacy features

Blockchains being transparent, it is easy to find the transactions done by different users in the platform. Hence a few platforms have enhanced privacy features so that the transactions made are not traceable. Coins from the Cryptonote family are a good example. Monero is an excellent example from cryptonote, which uses ring signatures, which obscures the sender and receiver’s address. The amount is also restricted by default.

πŸ”— Different types of Blockchains

While cryptocurrency platforms have a protocol that they should be open and permissible, it is not a hard and fast rule for blockchain technology. We have permissioned ledgers, which are also called private blockchains. An excellent example of private blockchains is enterprise blockchains like hyperledger platforms.

We also have permissionless ledgers, which are public blockchains. Good examples of permissionless are cryptocurrency platforms. We have hybrid platforms as well, which are a mix of public and private, leveraging the properties of both the platforms wherever required.

πŸ”— Applications of blockchain other than cryptocurrency

Blockchain technology has made its way to almost all the fields. Healthcare, supply chain, agriculture, energy trading, valuable goods/diamond digitization, shipping industry, trade finance, music, publications, art, gaming, etc. Blockchain being a niche technology, the adoption is still low, but the recent surveys across the industries only prove that they have started implementing the technology or looking to implement at the moment.

πŸ”— Non-crypto applications on top of cryptocurrency platforms

Ethereum has many DAPPs developed and operating on its platform, but we cannot say that these applications run on cryptocurrency applications. Ethereum is a broad platform with a multitude of smart contracts operating on them serving different purposes. There are applications on the top of the bitcoin platform which convey messages. Protocols like Counterparty, Factum, Colored Coins allows the creation of tokens to denote something with a fraction of bitcoin value.

πŸ”— Projects to tackle scalability issues

The main drawback of blockchain platforms is scalability, and many projects have been developed to address the same. Segwit, segregation of witness aims to remove the signature from the main block and store it somewhere else to increase the block’s space for more transactions.

We have sidechains that intend to transfer some of the workloads to an adjacent chain, called sidechain, which may or may not run on the same consensus algorithm but are equally secured. The hacking of the main chain doesn’t affect the side chain and vice versa. The sidechains are used to test innovations and implement smart contracts if they are not feasible to run on the leading network.

Conclusion

These are some of the facets to show how blockchain as a technology has grown to address the drawbacks from one stage to another. Many have speculated that the technology is not very much useful and is overhyped. But with all the developments since its inception and all the money being poured into the technology, we can only say that it is here to stay and improve a lot and prove itself for time and again.

Exploring The New Suite Features Of ‘CryptoNote’ Technology

Introduction

CryptoNote is an open-source protocol that essentially serves as an underlying technology for some cryptocurrency. Just like Blockchain technology, CryptoNote is also technology that is a backend for cryptocurrencies.

CryptoNote technology was primarily developed to provide extremely private features using advanced cryptography. What makes it unique is the egalitarian approach for making the network decentralized and censorship-resistance.

Origin of CryptoNote

The CryptoNote has had a history similar to that of Bitcoin, in terms of being mysterious. It emerged in 2012 and was published on Tor, and the author of the original whitepaper Nicolas Van Saberhagen is a pseudonym, which means that the identity of the author is still unknown. In fact, the identity of the author of the second edition of the whitepaper is also under the same pseudonym.

The original whitepaper discussed the privacy and flexibility that is deficient in Bitcoin. It also sheds light on the traceability and linking ability of transactions in Bitcoin’s β€œone-CPU-one-vote,” as explained by the creator of Bitcoin Satoshi Nakamoto. On the whitepaper, they claim to present more advanced features for decentralized cryptocurrency networks that are based on complicated mathematical analysis.

Entering the CryptoNote Technology

The CryptNote technology is similar to the blockchain technology, with few key differences. This technology is built under consideration of two features that make the payment network through this system fully anonymous. They are,

                        Untraceability & Unlinkability

Untraceability – For all the incoming transactions from the network, every sender is equally probable at the origin.

Unlinkability – A property where it is not possible to verify that two outgoing transactions are sent to one particular person.

When the proposal to launch the technology was made, there were many optimizations and improvements made to keep their technology stand apart from the crowd and hold its original principles along the way. The standard features that should be embedded in such technology are implemented as well. The following are the primary features CryptoNote has to offer.

  • Untraceability of payments
  • Unlinkability of Transactions
  • No Double-Spending
  • Blockchain Analysis Resistance
  • Egalitarian PoW

Cryptocurrencies backed by CryptoNote

There are several coins that are implemented using CryptoNote technology. All of the coins have this technology in them in some or the other way. In fact, there are even optimizations made to the current features that are then added to the cryptocurrency.

Bytecoin

Bytecoin is the first cryptocurrency that was created using CryptoNote technology in 2012. Being the first one, it was quite popular back then. This coin includes the exclusive CryptoNight mining algorithm along with the typical features of CryptoNote. Bytecoin was mainly developed to facilitate instant transactions with no fee for businesses, merchants, and customers in the inclusion of security, anonymity, and fast international payments.

Monero

Monero has been one of the most popular cryptocurrency when it comes to privacy. This open-source protocol and decentralized network community are highly dedicated to making Monero a powerful anonymous payment method. And not to mention, this coin is created under the assistance of CryptoNote.

Conclusion

Over the years, people are not completely satisfied with the features provided by the blockchain. Their focus has been on finding inefficiencies in this technology and coming up with other technologies satisfying those inefficiencies. And CryptoNote is one such technology that emphasizes on anonymity in cryptocurrency networks. This is a very broad property and will remain in development for long.
