An ÐApp (it is written with this strange Ð and pronounced as [Di-app], similar to how we say “e-mail” [i-meil]) is a decentralized application, that is, an app that does not depend on a central system , but it depends on the community of users that use it.
The decentralized application can be a mobile app or a web application that interacts with a smart contract to carry out its function.
If we briefly recall what an intelligent contract or smart contract was , we will say that it is a computer program that executes itself when the conditions that were programmed in its code are met.
To understand how an ÐApp works and its interaction with smart contracts, it is best to make a brief introduction comparing traditional web applications with the new ÐApps.
TYPES OF APPS
After knowing the characteristics that an ÐApp must have to be considered as such, and continuing with the purpose of this article, we will go on to differentiate the different types of ÐApps that exist.
We will make this classification of decentralized applications based on whether they have their own blockchain or whether they use the block chain of another ÐApp .
According to this criterion, we could differentiate three types of ÐApps:
Type I decentralized applications
These are the ones that would have their own independent blockchain .
In this case, and as we have already seen in the previous section, Ethereum would be one of these ÐApps, although the most famous in the world of cryptocurrencies is Bitcoin. Litecoin, Dash, Monero and many other “altcoins” would also fall into this classification.
Type II Decentralized Applications
The main characteristic of type II ÐApps is that they use the blockchain of a type I decentralized application instead of having their own . This type of ÐApps are protocols that work either with their own tokens or with the tokens of the blockchain in which they operate.
An example of this type of ÐApps would be Omni Layer . This decentralized application is built on top of the Bitcoin blockchain and is a platform for creating and trading digital assets and cryptocurrencies. Acting on top of the Bitcoin blockchain, Omni transactions are also Bitcoin transactions.
Another example of a type II ÐApp, this time based on the Ethereum blockchain, would be the Raiden Network .Dapps Development
This platform offers a scalability solution within the Ethereum network when it comes to allowing almost instantaneous and low-cost payments. The main idea of Raiden Network is to take advantage of a network of payment channels that allow value to be transferred safely without the need to involve the Ethereum blockchain in each transfer, which would multiply its speed.
Type III Decentralized Applications
Finally, type III ÐApps would be those that use the protocol of a type II decentralized application like the ones we have just seen.
These applications also work with their own digital tokens or with those of the ÐApps on which they are based, as was the case with type II ÐApps.
A type III ÐApp could be Safe Network , which uses the Omni Layer protocol (a type II ÐApp) to issue its own cryptocurrency — Safecoin -, which in turn can be used to purchase distributed file storage, for example.
Or continuing with the Raiden Network example, a type III ÐApp in that case would be µRaiden (read as ‘Micro Raiden’).
Where Raiden Network seeks to allow transfers through a network of bidirectional payment channels, this ÐApp performs the functions of making micropayments through unidirectional payment channels.
To finish understanding the types of ÐApps 100%, we will put a simile that is better known to all of us in our day to day:
A type I ÐApp could be the equivalent of a computer operating system. The operating system could be said to be the basis for everything that can be done on the computer. Some of those that can come to mind are Windows, Mac OS or Linux, and for mobile devices, Android or iOS.
A type II ÐApp would be the equivalent of a general purpose program, such as a word processor (Word), a spreadsheet manager (Excel) or a file synchronization system such as Dropbox.
And finally, a type III ÐApp would be the same as a specialized software solution for that word processor, that spreadsheet manager or that file synchronization system. In other words and following the previous example, a type III ÐApp would be a kind of plugin or tool that adds some kind of service to Word, Excel or Dropbox. ethereum token development company
Many decentralized systems are developing the search of independent operations with the help of an Ethereum Token Development Service.
New tokens are supplied easily, due to an increased activity in the blockchain network.
These tokens represent any asset in the form of gold, any financial transaction done for settlement, and financial instruments like bonds and shares.
All the tokens have some special features like-Fixed supplyConstant inflation rateUseability for a variety of purposes.
Various types of Ethereum Token Development Services are- Token creation - Both fungible and non-fungible tokens will be createdToken Migration - Tokens can be migrated from the Betanet to Mainnet in the blockchain network, therefore flexibility is maintained.
Cold Storage - The security of tokens should not be hampered with a robust or cold storage mechanism.
The Ethereum network is taking a big step towards a scalable PoS blockchain.
L to lack of scalability and high rates of gas are the main problems.As one of the largest cryptocurrency platforms for decentralized applications, Ethereum has been dealing with network congestion reflecting the high gas fees that people have had to pay with each transaction.
Since the beginning of the year, at times, the cost of facilitating transactions in the Ethereum ecosystem has hovered around the range of $ 16-20, reaching $ 100 in DApps such as Uniswap that have a high volume of transactions.From this point of view, the transition to Ethereum 2.0 (Eth2) as a solution designed to address scalability issues, as well as solve the problem of skyrocketing gas rates, is a welcome respite from the Ethereum community.Eth2, or Serenity, will be a technical update that will move the Ethereum blockchain from a proof-of-work (PoW) protocol to a proof-of-stake (PoS) blockchain.
Named after the host city of Ethereum Devcon's inaugural convention, Berlin is a precursor to the larger London hard fork, incorporating four Ethereum Enhancement Proposals (EIPs) that address gas prices and allow new types of transactions.Berlin's EIP-2565 consists of the reduction of gas rates on Ethereum.
This mechanism uses a feature called Modular Exponentiation (ModExp) to benefit Ethereum users who need to run services on the Ethereum network.The EIP0-2718 protocol makes all types of transactions backward compatible, thus facilitating the incorporation of new transaction logic in Ethereum.
However, the update was postponed several times due to concerns about potential vulnerabilities caused by the centralization of the update.Furthermore, the consensus in the Ethereum community was that Berlin would have less of an impact in the short term, but that it would pave the way for the long-awaited London hard fork EIP-1559 protocol.London's hard fork: increased elasticity of blocksEthereum's London hard fork is part of Ethereum's roadmap on its way to the Eth2 launch.
