What is a decentralized application?
Decentralized applications (or Dapps)includes serverless provisions that might be run mutually on the customer side and inside a blockchain based dispersed network, for example, such that Ethereum.
The customer tool manages the front-end and consumer credentials, at the same time as the back ends runs within a disbursed network of computers that offer for the processing and storage necessities.
Features of Decentralized applications
- Open Source: The application’s code structure must be mostly available for public research.
- Decentralized: The application’s data should be stored on a public and decentralized blockchain platform.
- Incentive: The application must utilize tokens/digital resources to reward its network supporters.
- Protocol: The application must generate tokens using a cryptographic consensus algorithm to demonstrate proof of value.
Building Decentralized Applications
Publish White Paper on the DApp
Publishing a white paper defining the blueprint, features, and technicalities of the DApp is crucial, and is also the very first step. Your whitepaper should address a problem you wish to solve. It should state the intentions and goals of the Dapp.
Gather Community
Gain community involvement by stating the plan and discussing the proportion that will go to the development budget and other essential allocations. Being transparent about the distribution of tokens is critical.
Begin Development
When all is stated and achieved, after gaining the price range and tuning the idea, it’s time to start development. And once you have got commenced, it turns crucial to percentage weekly or month-to-month updates that help in constructing surroundings for community individuals.
Launch the Product
Launch the product with release notes stating the maintenance plans so that the community is involved.
Overview
There are different kinds of people in the world, who have different languages, different cultures, different eating styles but one of the things that brings them together is money, which is everybody's necessity.
In today’s fast moving and developing era, we need a safe and secure platform to be able to make online transactions, for whatever purpose they might be. In whatever transactions we do, banks are the third party involved in it, and they have all records of our transaction and of one’s account holdings.
Blockchain Technology aims at removing this third-party involvement and keeping the transactions only limited to the sender and the receiver. A broad idea behind this technology was to build a secure platform where safe transactions could happen in a very transparent manner.
With the help of Blockchain technology, we can save ourselves from any kind of overheads and third party involvements and send or receiving money could be as hassle-free as sending emails. BlockChain Technology is a peer to peer software technology that protects a digital piece of information.
What is BlockChain Technology?
The origin of Blockchain technology is a little uncertain and still for experts to find out for sure. It is said to be invented by a person or a group of people known by the name of Satoshi Nakamoto in the year 2009.
Initially, it was developed to enable digital transactions between two parties in an anonymous fashion, without having the need of a third party to perform verification of the transaction.
The main inspiration behind the development of such a great technology at the time was to facilitate the transfer of Bitcoins, but it later caught on and is today being used for many other important things.
The blockchain technology is an open system for transaction processing that follows distributed ledger approach whose goal is to automate the processes and reduce data storage costs and provide data security and eliminate duplicates.
We can also say that BlockChain is a method of recording data, i.e., transactions, contracts, agreements that need to be recorded independently and verified as they are happening.
A very good way to understand the concept of Blockchain technology is the google docs analogy. Just the way Google Docs shared between two people enables both of them to make changes to the document at the same time and visible to the other party, similarly the transparency of blockchain works.
BlockChain sounds like a revolution and is the underlying Technology behind Bitcoin. Truly, BlockChain is a mechanism that brings everyone to the highest degree of accountability, i.e., no more missed transaction, no more third party involvement in the transaction.
Blockchain guarantees the validity of a transaction by recording it not only on the main register but also by connecting distributed system of registers, and all of which are connected through a secure validation mechanism. It may have been invented to create the alternative currency Bitcoin but can be used for other purposes like online signature services, voting systems, and many other applications.
It's a good way instead of sending our payment information through servers, in BlockChain Technology all transactions are Copied and cross-checked between every computer in a system, which becomes very safe at scale.
BlockChain Technology is a type of distributed ledger that means a database that is consensually shared and synchronized across network spread across multiple sites, institutions. Blockchain provides an unalterable, public record of digital transactions in packages called Blocks. These digitally recorded “Blocks” of data are stored in a linear path, and each block contains cryptographically hashed data.
Key Applications of BlockChain
- Capable of transforming
- Making transaction faster
- Reducing cost
- More security
- Transparency
- Seamless and simultaneous integration of transaction
- Settlements and ledger updates directly between multiple parties
- Creates a secure way to share information
- Conduct transactions without the need for a single, central party to approve them.
- Only authorized network members can see details of their transactions, providing confidentiality and privacy.
- All updates to the shared ledger are validated and recorded on all participants shared ledgers, which drives security and accuracy.
- All updates to the ledger are unchangeable and auditable. Network members can accurately trace their past activity.
How Does BlockChain Works?
The Blockchain technology enables direct transactions between two parties without any intermediary such as a bank or a governing body. It is essentially a database of all transactions happening in the network.
The database is public and therefore, not owned by any one party, it is distributed that is, it is not stored on a single computer. Instead, it is stored on many computers across the world. The database is constantly synchronized to keep the transactions up to date and is secured by the art of cryptography making it hacker proof.
The basic framework on which the whole blockchain technology works is actually two-fold first is gathering data (transaction records) and the second is putting these blocks together securely in a chain with the help of cryptography.
Say a transaction happens, this transaction information is shared with everybody on the blockchain network. These transactions are individually timestamped and once these transactions are put together in a block, they have timestamped again as a whole block.
Now, this complete block is appended to the chain in the blockchain network. Other participants might also be adding to the network at the same time, but the timestamps added to each block takes care of the order in which the blocks are appended to the network.
The timestamps also take care of any duplicity issues hence, everybody on the network has the recent version of the chain available to them. The main cryptographic element that makes this whole system tamper-free is the hash function.
Each block's information is taken and a hash function is applied to it. The value computed from this is then stored in the next block and so on. So in this way, each block’s hash function value is being carried by the next block in the chain which makes tampering with the contents of the block very difficult.
Even if some changes are made to the block, one could easily find out because that block’s hash value would not be the same as the already calculated value of the hash function that was stored in the next block of the chain.
Blockchain works as a network of computers. Bitcoin photography is used to keep transactions secure and also shared among those in the network after the transaction is validated, the details of the transfer are recorded on a public ledger that anyone on the network and sees in the existing financial system essentially ledger maintained by the institution access the custodian of the information.
But on a blockchain the information is transparently held in a shared database and no one party access the movement, thus increasing the trust among parties.
How Bitcoin Transaction Works?
For everyone, it's easy to download a simple piece of software and install it on the computer. But to use Bitcoin which is a decentralized be out of your system, we do not need to register an account with any particular company or handle or any of your personal details, once you have a wallet you can create addresses which effectively become your identity within the network.
Suppose party A wants to send money to party B in the form of Bitcoins. For both party A and Party B, the transaction is collected in a block. A block record some or all of the most recent Bitcoin transactions that have not yet entered any cry of blocks, the new block is then broadcasted to all the parties or so-called nodes in the network the parties in the network approve that the transaction is valid through a process called mining.
Building Blocks With BlockChain
A very simple definition of blockchain is that “the blockchain is distributed, digital ledger.” One of the key features of the blockchain is that it is a ‘Distributed Database’ that is to say, the database exists in multiple copies across multiple computers.
Concept of BlockChain Technology
- Shared View - One of the most powerful features of BlockChain Technology is it’s shared a view of data for all participants in a peer-to-peer network. Transaction records can be shared but cannot be altered. Shared views have two approaches i.e. Traditional Approach where each party maintains their own independent ledger and Blockchain Approach where all parties share and maintain the same ledger.
- Cryptography - Cryptography is used to establish identity and protect the integrity of the underlying data. One of its concepts is hashing and this concept is used in the blockchain technology. Hashing is an effective means of determining if any piece of data has been changed or not. It generates a fingerprint for a piece of data by applying a cryptographic function to it. Changing one character in the original string results in a completely different hash value. Also, the original string cannot be reverse engineered from the hash function.
CryptoCurrency - Everything You Need to Know
Cryptocurrency is a virtual currency which uses cryptography for security. The main defining features of this currency which make what it is are its decentralized nature, transparent ledgers and it's security feature which makes it resistant to any kind of malicious manipulation. Bitcoin is the is the first and the most famous cryptocurrency. It was invented in 2009 and has seen an enormous rise in value ever since.
The cryptographic technique that it follows is SHA-256, it is a hash function that is used to encrypt every transaction before being added to the blockchain. The underlying and main aspect on which cryptocurrency works is that all the transactions happen in a transparent and decentralized ledger for everyone to see and verify if need be. One can go back to the very first transaction of a user to verify their credibility by tracking back in the ledger.
Benefits of CryptoCurrencies
The advantages of cryptocurrency are much fold. To name a few would be:
- No Fraudulent activities - Transactions happening in this process cannot be reversed or in any other way be tampered with, without at least letting anybody know. The whole architecture is such that any discrepancies cannot go unnoticed and can be detected.
- Faster transactions - The traditional way of settling payments involves a trusted third party, namely banks mainly, this makes the process take more time. In cryptocurrency, since the payments are peer-to-peer without any involvement of a third party, the payment process happens immediately without any delay. No Overheads- With the elimination of third party involvements, the overheads in the form of service fees that these institutions charge are also eliminated. This makes cryptocurrencies more cost-effective.
- The integrity of identity - Unlike credit cards, which always have a risk of getting misused since all the information regarding it is given to the vendor, this mode of payment does not divulge any more information than required and only pushes the amount of money that is required to be paid.
How is Blockchain Changing Money and Business?
Blockchain technology is likely to have a great impact on next few decades. Currently, Blockchain is not the most thundering concept in the world, but it is believed that it will be the next generation of the internet. For the past few decades, we've had the internet for information.
The crucial difference between Internet and BlockChain is that the Internet enables the exchange of data, blockchain could enable the exchange of value, i.e., it could allow users to carry out trade and commerce across the globe without the need for payment processors, curator, and settlement and adjusting entities. Trust is a very crucial thing, and blockchain is one of the biggest technologies that peer.
Trust enables people everywhere to trust each other and transact peer established, not by some big institution, but by collaboration, by cryptography and by some smart code. And because trust is native to the technology, so we can say that it's “The Trusted Protocol.”
