What kind of applications can I build quickly using blockchain?

Building a blockchain app or DApp requires various skills and knowledge to apply practically. You must be familiar with languages such as C++, Python, JavaScript at the base and special focus to be given for Simplicity, Solidity, and Rholang. If you are aware of these, you might start with basic programming and build a blockchain app easily. You might want to hire a blockchain developer for your business if it requires a sophisticated app with a better interface and functionalities.

If you are more interested in blockchain app development company, you may consider taking up an online or offline course from a reputed blockchain training institute. This would help you improve a lot and also prepare you to be a part of the IT sector in the near future. Also, check out the existing apps, their codes from websites such as GitHub and learn to do it by yourself without errors.

What is the basic idea of building the blockchain network?

There’s a ton of the hype around blockchain. I’ve read that blockchain development company can erase global hunger, make the world corruption-free, end poverty and do a lot more without breaking a sweat. Unfortunately, that’s not true. So, step 1 is to identify a use-case that makes business sense.

There are 3 things that blockchains can do very well:

·        Data Authentication & Verification: this includes immutable storage, digital signatures and encryption. Data in almost any format can be stored in the blockchain. Blockchains can create public-private key pairs and also be used for generating and verifying digital signatures.

·        Smart Asset Management: this includes issuance, payment, exchange, escrow and retirement. A smart/crypto asset is the tokenized version of a real-world asset e.g. gold, silver, oil, land.

·        Smart Contracts: This is a term most often misunderstood, but that’s something for another day.

Step 2: Identify the Most Suitable Consensus Mechanism

The original blockchain, which powers the bitcoin crypto-currency, used proof of work as a consensus mechanism. But today there are multiple distributed ledger systems that offer a host of consensus mechanisms such as Proof of stake, Byzantine fault-tolerant, Deposit based consensus, Federated Byzantine Agreement, Proof of Elapsed Time, Derived PBFT, Redundant Byzantine Fault Tolerance, Simplified Byzantine Fault Tolerance, Federated consensus, Round-Robin and Delegated Proof of Stake.

There are many top blockchain development company platforms out there today and most of them are free and open source. Depending upon the consensus mechanism you chose in step 2, you need to select the most suitable blockchain platform.

Some of the more popular platforms, in alphabetical order are:

1.          BigChainDB

2.         Chain Core

3.         Corda

4.         Credits

5.         Domus Tower Blockchain

How do I add blockchain in my app?

A blockchain is a network that shares all data among its peers, storing this data chronologically in blocks. This means that once something occurs in a blockchain network (for example, a transaction or a data exchange), it’s shared with all members of the network, and everyone has a record of this action on their own devices.

To set up a blockchain, you’ll need from a few gigabytes to a terabyte of storage space. Since mobile devices don’t have so much space, DApps usually function on just a part of a chain.

There are two types of blockchains based on the type of network.

A permissionless blockchain is accessible to all members of the network and is available on any device. Every user can access the code, verify transactions, interact with others, and stay anonymous. Bitcoin, for example, is permissionless.

Permissioned blockchain technology allows only authorized, participants. All users have roles and permissions. A permissioned blockchain has rules that regulate transactions between network members. This type of blockchain is great for managing operations within organizations.
