Java For Blockchain App Development
It is based on OOP and has lots of libraries. It has monitoring tools like JMX or Java Mission Control to help manage applications. It is an architecture-neutral, secure and independent platform. Also, it is fast, supports pluggability, is easy to maintain, effortless memory cleaning and is less intense difficulty level is lower than C and C++. NEM, IOTA, NEO, and Hyperledger Fabric are some best blockchain projects in Java.
What Is Happening Here
Can you see the difference between the two blocks of codes?
When we are using the move semantics, the value of b need not be unchanged. That is the difference between copy semantics and move semantics. The biggest advantage of move semantics is that you can get copies of certain data only when you need them, which greatly decreases redundancy in the code and gives a huge performance boost. So as you can see, this efficient memory management and high performance are both desirable for the blockchain.
Feature #: Move Semantics
One of the most interesting aspects of C++ is move semantics. Move semantics provides a way for the contents to be moved between objects rather than be copied outright. Lets check out the differences between copy semantics and move semantics. .
- a = b
So what is happening here? The value of b goes into a and b remains unchanged at the end of the whole thing.
Now, consider this.

Blockchain Coding Difficulty Challenge #: Isolation
What is deterministic behavior?
- If A + B = C, then no matter what the circumstances, A+B will always be equal to C. That is called deterministic behavior.
- Hash functions are deterministic, meaning As hash will always be H.
So, in blockchain development, all transaction operations must be deterministic. You cannot have a transaction that behaves one way and then behaves another way the next day. Similarly, you cannot have smart contracts that work in two different ways in two different machines.
The only solution to this is isolation. Basically you isolate your smart contracts and transactions from non-deterministic elements.
So, we have discussed the main problems that blockchain developers face. Now lets finally check out some of the languages that the developers can use to code on the blockchain.

Blockchain Coding Difficulty Challenge #: Security
Blockchains, as David Schwartz puts it, should be fortresses. Firstly, the code is public and open for all to see. Anyone can look over the code and check for bugs and vulnerabilities. However, unlike other open code resources, the downside of finding vulnerabilities on blockchain code is massive. Any programmer can hack in and get away with potentially millions and millions of dollars. Because of these legitimate security concerns, development on blockchain is usually very slow.

C++ The King Of The Hill
The granddad of every programming language out there, C++ is, still today, the king of the hill. Since its an object- rather than a process-oriented extension of the C language, C++ interacts perfectly with blockchains inherent structure.
This programming language can manipulate the blockchains blocks & chains as easily as binding LEGO bricks together to build a toy castle. C++ is also flexible enough for blockchain since it provides full control over CPU and memory usage, dealing nicely with the high resource demand needed to give quick service to all nodes at the same time.
C++ is the language that was originally used to write Bitcoin, but it is used even today to implement a broad range of ground-breaking blockchain applications.

Erlang And The Permaweb
Somewhat of an underdog among the other mainstream programming languages used for blockchain, Erlang shines as a less-known gem for the amazingly unique applications developed with it. Erlang is the perfect candidate for building the exceptionally robust back-ends systems needed to achieve the scale required by the most revolutionary broad-scoped blockchain projects.
In fact, today, 90% of Internet traffic is routed through Erlang-running nodes. Its inherent fault tolerance is just one of the characteristics that make Erlang superior to other programming languages to build, for example, peer-to-peer networks in a blockchain ecosystem.
Lets have a look at one of the most prominent examples.
Arweaves Permaweb is one of these amazing blockchain technologies. It allows for permanent permanently archiving web content in a sort of parallel world wide web. This new web uses blockweave, a blockchain-based distributed ledger technology, and has been up and running for a few years already. Other than being able to store information that is now lost in the traditional web, the decentralized web may also provide a fantastic solution to internet censorship in countries such as Russia, China, or other African nations.
In fact, as Sam Williams, Arweave co-founder and CEO explained Information on the Permaweb cannot be manipulated or removed giving citizens the ability to hold their governments accountable and to help preserve democracy and its already working!

What Is A Programming Language
Programming languages are essential to ensure that blockchain networks and crypto infrastructure are safe and secure.
Their role of the programming language is simple. It enables a computer to understand the Blockchain instructions. However, there is some overlap in the programming languages to develop traditional software and technologies. Therefore, in blockchain platforms, the workflows and skills may require to create successful projects.
Maintaining a public blockchain using the programming language is not an easy task. The language code should be absolutely bulletproof to ensure that hackers cannot attack it. Therefore, language creations may slow down the process substantially as developers need extra effort on every loophole.
Programming languages are instrumental to ensure that the blockchain network can run smoothly in terms of transaction processing. To achieve this automation, programmers often use smart contracts. When predetermined conditions are met, the programming code enables these agreements between parties. The benefit of using the language is that it eliminates middlemen. Therefore, it does not need to eradicate lawyers or notaries. Anyways, it can take intensive levels of coding to ensure the right.
Besides these, some blockchain includes the development of as well as the execution of crowdfunding initiatives.

Section : Adding The Blocks
Firstly, we will need to know what the last block in the blockchain currently is. For that we use the getLatestBlock function.
getLatestBlock Now that we have determined the latest block, lets see how we are going to add new blocks.addBlock
So, what is happening here? How are we adding the blocks? How are we checking if the given block is valid or not?
Remember the contents of a block?
A block has the hash of the previous block right?
So, what we are going to do here is simple. Compare the previousHash value of the new block with the hash value of the latest block.

If these two values match, then this means that the new block is legit and it gets added to the blockchain.
What Are Smart Contracts
A smart contract is a computer program that automatically executes actions according to the terms of the contract without intermediaries. For example, if you want to purchase a piece of land using a smart contract mechanism, your land ownership documents will be sent to you immediately after your payment is completed. You dont need to trust a third-party site to transfer the ownership after making payments.
Also, you can see smart contracts in action in decentralized exchanges , like PancakeSwap, which allows you to exchange your tokens for another token. If you have BNB, you can easily exchange it for Ethereum without having to talk to customer support.
Smart contract programming languages allow you to write programs that implement smart contracts on the blockchain.
So, what are the top smart contract languages, you asked? Lets get into it.

Section : The Genesis Block
What is the genesis block?
The genesis block is the first block of the blockchain, and the reason why it is special is that while every bock points to the block previous to it, the genesis block doesnt point at anything. So, the moment a new chain is created, the genesis block is invoked immediately. Also, you can see a createGenesisBlock function wherein we have given the data of the block manually:
return new Block
Now that we have built the genesis block, lets build the rest of the chain.
Which Blockchain Programming Languages Are Most Popular
Due to the blockchain ecosystems distributed and complex nature, it is impossible to precisely quantify programming language use across all platforms, apps, and smart contracts. However, some experts have come up with methods of approximating such information indirectly.
