With the advent of Blockchain technology, the application of internet and IT is rapidly expanding to other non-conventional areas. Asset management is one of them. Think of a situation where you buy an apartment from a seller without signing single paper agreements, Or you sell your apartment without writing lengthy legal agreements and without the involvement of a third party like registrar. Yes, it is possible and it is the future. Smart contracts are the digital version of contracts and it can be used to exchange the digital assets. Smart contracts are used to exchange anything of value in a more secure way without any middleman. Yes.. they are some lines of code that facilitate the same purpose of a written contract.

So if there is no guaranteeing authority how the agreements are implemented? It is the most interesting part of the smart contract. As we mentioned earlier the transactions are totally completed via computer networks and the payment methods will also be compatible with it.  Generally, the payments are done through cryptocurrencies like Bitcoin and it is often self-executable.

Smart contracts are usually created with the help of contract development tools and written using programming languages such as Solidity, Java, Go, Python. Out of which Solidity is the most popular one.

APPLICATIONS:

The applications of smart contracts are many and some of them are:

Insurance Policies: Today it is taking a long period of time to claim an insurance after an accident or any other insured event has occurred. This process is manual and increases the administrative cost. This can be reduced by automating claims processing, verification, and payment. Thus the customer can claim the insurance shortly after an insurance event happens.

Property Sale: Using the smart contracts for buying and selling of a property decreases the auditing cost. This also improves the transaction efficiency and strengthen the confidence in the system.

Digital Identity: Digital identity like personal data and assets can be protected and shared to trusted channels more safely with smart contracts.

Personal Health Tracking: Tracks patients health-related action and automatically generate reports. It can share the data to trusted channels and same time protect it from unauthorized accessing.

Voting: Validates voter criteria, add votes to the blockchain and develop the result according to majority vote.

Smart contract codes and Smart legal contracts,  these are two terms which are often confused while talking about the smart contract. Actually, the smart contract can be classified into these two types. Let look them individually.

SMART CONTRACT CODES:As you can see from our previous blogs, blockchain applied technologies are largely based on smart contracts. In the case of ‘Hyperledger’ or Ethereum there many internal check and balance conditions which regulates the working of such frameworks, these are smart contract codes. These are also self-executable codes which ensure the security and consistency of the framework.

Here is an example of smart contract code used in Ethereum Blockchain

contract token { mapping (address => unit) public coinBalanceof ; event coinTransfer(address sender, address receiver, uint amount) ; /* initialize contrct with initial supply tokens to the creator of the contracts*/ function token(uint supply) { if (supply == 0) supply = 1000 ; coinBalanceOf[msg.sender] = supply ; } /* very simple trade function */ function sendCoin(address receiver, uint amount) returns(bools sufficient) { if (coinBalanceOf[msg.sender] < amount) return false ; coinBalanceOf[msg.sender] -= amount ; coinBalanceOf[receiver] += amount ; CoinTransfer (msg.sender,receiver,amount); return true; } }

SMART LEGAL CONTRACTS:Smart legal contracts are the real legal agreements used to manage the transaction of digital assets. Like the apartment rental case, we discussed first. It has a legal validity and its scope is often outside the blockchain.

WORKING:There are mainly three steps involved in the working of a smart contract:

Coding: As mentioned earlier smart contracts are computer programs, coding is essential in it. Proper coding ensures that the contract will run exactly according to user needs and conditions. Thus it should automate “if this - then “part of the traditional agreement.

Distribution: Once the code is ready it is encrypted and sent to Blockchain network or the distributed ledgers for execution.

Execution:  When the contract arrives on the network, each node in the network will come to an agreement on the execution of the contract. After such an agreement is established by networks then manipulation is not possible.

ADVANTAGES Following are some advantages of Smart Contracts

1. Security: The control over the execution of smart contract codes is distributed over the network, it eliminates the risk of manipulation.

2. No intermediaries: Smart contracts allows the parties to enter the agreement without the intermediaries.

3. Lower cost: As it requires only less human intervention, and it reduces the cost.

4. Transparency: It creates an environment of trust as the conditions in the agreement are visible to all nodes in the network.

5. Faster settlements: Since settlements are done digitally, it happens instantly and will be faster

DISADVANTAGES:

1. Rogue contracts: As smart contracts are anonymous and self-executing it has a chance of conducting illegal activities by terrorists, smugglers etc.

2. Errors in code: When bugs or errors get in the code it may lead to procedural difficulties related to identifying errors and the party who is responsible for the error.

The fundamental part of blockchain technologies is hash functions. If you understand hash functions, you can understand the related concepts more easily.

What is hashing? To get an output of a fixed length we use hash functions, It will not consider the length of the input given.The hashing function is executed with the help of a hashing algorithm.

How Hashing Technology used in Blockchain? To write new transactions into Blockchain we use hashing and it is a mathematical process.We must ensure the following features to consider a hash function as a secured one: Even if we execute the same input multiple times, the output or hash should be same.It should produce the output quickly. It should be impractical to find an input ’A’ from H(A).There should be a huge change in the hash with the small change in the input.There should be a unique value of the hash.

Data structures Pointers and linked list are mainly two data structures used in Blockchain.The pointers also store the hash value of the previous block including the address. The blockchain is a linked list in which each node stores a hash pointer and a data header.

Mining process This process is used to add new blocks to the Blockchain.If it is a valid transaction, the miners add the transaction to Blockchain.Instant creations of more hash functions can result in the collision of hashes.

You might have read a lot about the Blockchain and its undisclosed concepts. As the definition says ‘The Blockchain is a public ledger used to record all the transaction happened in a particular network’. currently, Blockchain is spreading to various ideas like trading, file storage, identity management, medical records management and education etc.As Blockchain is growing at such an incredible speed there must be a very strong and secure data structure behind this to support the entire blockchain system.

do you have any idea how exactly a block is implemented? If you are still in a dilemma then read on. Let’s explore ‘how exactly blockchain is implemented?’ You might be aware of the concept Distributed computing and the famous Linked list Data structure.Really...?  You don’t have to be a ‘geek’ to understand those two. So what we have to say is Blockchain is a well-blended combination of these two concepts.

Blocks are the basic building units of the blockchain. Initially, we will be creating a block and then link this block to the chain. There won’t be any abandoned blocks in the blockchain. All the blocks are interconnected together.

Block Similar to a linked list, the Blockchain is a group of blocks interlinked together, in which each block will have the following fields.

1) Block: It is used to store the block value 2) Nonce: An arbitrary value used for finding a valid hash value. 3) Data: Store the data (transaction details) 4) Prev: Store the hash of the previous block 5) Hash: Hash value for the current block which can be used to refer this block.

Suppose we are creating the first block in a Blockchain, then consider the example. • Here Block No is ‘1’ • Nonce string is ‘3522’ • ‘Hello World’ is the Data part • ‘0000fdgydfs5434hbsdfjndsd’ is the hash value. • Previous value is ‘000000000000000000000’ (Zero) as it doesn’t have any previous block.

Hash The hash value, it is the very important thing in a block. The hash value is unique and it indicates a single block in a blockchain. It is acquired using a hash function algorithm like SHA 256 or keccak-25. The hash value is used to decide the validity of the block. A valid block will have a hash value that begins with 4 zeros. The hash value starting without 4 zeros are not valid block, and because of that mining should be done on that particular block to make that block valid.

The mining process is done by a miner, which is responsible for the validation of the blocks or transactions of a Blockchain.  The mining process is based on Merkle Root of the block, timestamp, previous block etc. After finishing the mining process, a valid hash key is produced which is a unique value. The nonce value is the number of Hash outs we have to perform in order to obtain a valid hash value. So the nonce value will also be changing after the hashing. Sometimes the miner has to perform a number of Hash outs before getting the targeted hash value. Whenever a new block is added to the Blockchain it must contain the hash value of the previous block and a default hash value for that represents the particular block.

As per the distributed behavior of the blockchain, each and every node in the distributed network will have the same copy of the blockchain and whenever a transaction occurs in the network it will be updated in its corresponding block after the verification only and it should be updated in the other peers also. But what if two distinct peers got different hash value and both declare as valid? In such case, a democratic method is used for verification. The hash value that majority of the peers holding will be considered as the actual value.  

Tokens The token is a term used in Blockchain to control financial transactions. All the digital asset movements in the network are saved in the tokens called ‘tx’. Each block will have a token in which the transactions are recorded or saved and we can see any transactions between two clients here. The Miners dig through the transactions history of the clients in order to validate a new transaction. Since the miner has the copy of the public ledger, it is very comfortable to go through various blocks and validate the transactions. For validating a financial transaction, the miner will make sure that the client who transferred the amount is having that much amount in his wallet. He can verify it by going through the transactions history of the client. If the client does not possess that much amount, then the miner will not verify that transaction.

Coinbase In the case of the initial transaction of a client, it is not possible to validate the amount as he does not have a transaction history for checking. In such a case, the Blockchain uses a term called ‘Coinbase’ to start the transaction. Each client will be having a ‘Coinbase’ and he can directly save some amount to this Coinbase. Then the remaining transactions can be continued from here.

Immutable Nature of blocks Every node holds a copy of the whole Blockchain, so the security is a most important concern here. In a Blockchain, the security is maintained through the immutable nature of blocks. Once you add a block in a Blockchain it cannot be changed. You may add a new block, but you cannot make modifications in the previously added block. The Blockchain immutability is acquired with the two properties of the hash.

1. It is very difficult to calculate the actual data from the hash. 2. A small change in the data will make a big difference in the hash value.

As a distributed system, immutable nature of the blocks is needed in blockchains. As all the nodes in the network hold the same copy of the data anybody can make modifications on the block. But because of the immutable nature of the blocks, once a data is entered to the blockchain any changes on the data can be easily recognized by its hash value.

This nature is dangerous too since a very small change in data can make big changes in the hash value.  Furthermore, the possibility of the data loss is very less as every node keeps the copy of entire blocks.

We all hear about cryptocurrencies, as it is the most prior topic discussed in all over the world.Since the concept of bitcoin set fires on the minds of common people, many people is in research about the bitcoin concept and how to acquire it. so everybody should know, what exactly the bitcoin concept is ? in simple terms it is just like very other currencies that already exist around the world but the important difference is that cryptocurrency exist in a digital form of money that means there is no tangible currency but only some program snippets.

The most beneficial point or aspect of cryptocurrency is that the currency is self-controlled and there is no middleman involved to control the currency.The term “middleman” refers to the central banks or government authorities. Its security is guaranteed by sophisticated cryptographic algorithms.Now the question arising in your minds will be that “ as there is no one to issue and control the currency then How the currencies are generated ?” New units of cryptocurrencies are generated by a process called “Mining”.The first established cryptocurrency was Bitcoin, invented by a mysterious person named ‘Santhosi Nakamoto’.

Another currency named ‘Namecoin’ was created in April 2011.After this invention, many other cryptocurrencies have emerged and many of them became well known.This blog shares you the knowledge about the top ten cryptocurrencies circulating around the web currently.Before that, we can discuss some of the benefits of cryptocurrencies in a border context.

ADVANTAGES OF CRYPTOCURRENCY:

- Cryptocurrencies are global currencies i.e.no individual country or authority can control it.They are accessible and transferred to everyone and anyone around the world

- Cryptocurrencies are free from middlemen like banks and government authorities. So there is no middlemen fee for transactions and transactions are usually done faster.

- It is a more secure asset than traditional currencies. The sophisticated cryptography guarantee that only the sender and receiver can access the data.

- It is a more transparent monetary system now existing. The transaction history and data are stored in public ledger so that it is viewable to all stakeholders.

LIST OF TOP 5 CRYPTOCURRENCIES:

Now in the digital world, there are about thousand plus cryptocurrencies available now on the web and also a new one can be invented any time.The value of cryptocurrency can rise or fall quickly. Some of the most popular cryptocurrencies are mentioned below :

1. Bitcoin 2. Ether 3. Litecoin 4. Ripple 5. Namecoin

1. BITCOIN: The Bitcoin (BTC) invented by Santhosi Nakamoto is the first famous cryptocurrency.The details of the founder are still unknown and no one is neither sure about his existence.Bitcoin uses peer to peer network for its existance and transaction are done and verified by miners. Mining is the process of solving a complex mathematical problem to verify a transaction.This process needs high amount of computing power.By finishing the process of verifying transaction the miners get a fixed amount of bitcoin as a reward through this newly created coin also gets part of the network.Now in the web there are finite number of bitcoins say 21million is existing and according to the miner more bitcoins will be added to the network by 2024 The hashing algorithm(hashing technology) used in bitcoin is SHA-256 (Secured Hashing Algorithm-256). And POW algorithm is used by the network to decide the next block to be added to the Blockchain.

Mining in Bitcoin Mining is the process of adding a new block to the Blockchain. As a new block arrives the contents of the block is hashed first. This hashed output is concatenated with the nonce and once more it gets hashed.The resulting hash is compared with the difficulty level it is done to identify the block is below or above the fixed difficulty level if it is less, then the block is added, else the nonce gets changed and the process is repeated until it reaches the target.

As the transaction process gets completed in a bitcoin network, the user pushes it to the network. So that the transaction can get verified by some participants in the network called miners.The process is as follows. When a new block arrives, all the contents of the block is hashed first. Then this hashed output is concatenated with a random string called ‘nonce’ and is hashed again. The resulting hash is compared with the difficulty target. If it is less than difficulty level then block is added, else the nonce is changed and the process is repeated till it meets the requirement. This process of verifying the transaction is known as mining.

2. ETHER : Ethereum is specifically designed to develop and run smart contracts and decentralized apps.So that we say ethereum is another type of decentralized blockchain network.Ether is the fuel of ethereum founded by Vitalik Buterian and launched in 2015.Currently, the total supply of ethereum is estimated to 60million. Ether is another type cryptocurrency which is used in the distributed application platform Ethereum. Ethereum is specifically designed to develop and run smart contracts and decentralized apps.So that we say ethereum is another type of decentralized blockchain network.Ether is the fuel of ethereum founded by Vitalik Buterian and launched in 2015.Currently, the total supply of ethereum is estimated to 60million.

Like in bitcoin Ether mining also indicate the verification of a transaction is done in Ethereum network. In Ethereum network a new block is added in every 15 seconds and currently, the reward for adding a new block is 3 Ether coins.

3. LITECOIN : Litecoin was launched in October 2011 by Charles Lee. It is an open source peer-to-peer network that is fully decentralized without any centralized authority. It has a market cap of around $180 million. LiteCoin little bit complex than previous two. Though the working principles are similar. There are some differences too. Open source Cryptographic protocol is the base of LiteCoin. A new block is processed in every 2.5 minutes and it uses ‘Scrypt’ for mining process. Since the mining is a little bit harder in LiteCoin the miner gets 25 LiteCoins for every new block.

4. RIPPLE: Ripple is used as both cryptocurrency and open payment network where the currency is transferred. It was released in 2012 and was invented by Chris Larsen and Jed McCaleb. Ripple coin is labeled as ‘XRP’. The current market for Ripple coin is $243 million. The ripple coin is mainly known for its strong focus on banking market and real-time settlement.

Ripple uses a medium known as Gateway that enables any person or organization to put into or take money out of the Ripple pool. Maybe the gateway mechanism is similar to present banking system but the shared open ledger makes the difference. Ripple is slowly becoming popular. Companies like Santander, UniCredit, UBS have already adopted it and Payment networks and Banks are increasingly attracted towards it.

5. NAMECOIN: Name Coin is another cryptocurrency which has many similarities with Bitcoin. In fact, it uses the same code of Bitcoin. And just like Bitcoin it also uses the Proof-of-work algorithm and SHA-256 Hash algorithm. The total supply of the Namecoin is limited to 21 million. Namecoin technology solves the problem of Zooko’s triangle, where anyone can register arbitrary human-readable names in a decentralized and secure way. These names can be used to create online identities. Namecoin was invented in April 2011 by Vince. NameID was launched in June 2013.
