In technical terms, a blockchain is described as a digital transaction record. The title comes from its structural elements, in which single-list documents, called blocks, are connected called a chain. Blockchains are mainly used to record digital transactions. These transactions made up with cryptocurrencies, such as a Bitcoin. Any transaction added to a blockchain is verified over the Internet by multiple operating systems and devices like computers.

Blockchain is a decentralized program, so it’s like a record, except one person, doesn’t keep it, it’s distributed, and any interested party can hold the record book and maintain it. The blockchain is a modern and innovative technical idea which is why more tech geeks are participating in it.

These systems form a peer-to-peer network, designed to track different types of blockchain transactions. They work together to make sure any digital transaction is legitimate before adding it to the blockchain. This distributed computer network means that no machine can add invalid blocks to the chain.

3D Technology is a way to provide real life experience using geometrical shapes and patterns. 3D Technology refers to a variety of devices that provide real life appearance on screen. 3D Technology uses 3 dimensional geometric shapes to make the object look real. In recent years, 3D technology has developed significantly. It is being used in almost every sector which deals with screen and data display

When any new transaction or a group of transactions (named as blocks) is added to a blockchain, a cryptographic hash created from the contents of the previous block, and it is used to connect it to the last block. It ensures that the chain never splits and that each block is registered forever. This is therefore purposely difficult to change past blockchain transactions, as all subsequent blocks must first be changed.


Though blockchain is commonly recognized for its usage of cryptocurrencies including Bitcoin, Ether & Litecoin, there are also many other applications of this technology. It allows for “smart contracts,” for example, to be enforced when certain conditions are met. It provides for an electronic escrow system for two-party transactions. 

Potentially, blockchain can be used to allow individuals to pay each other without a central clearing point needed for ACH and wire transfers. It has the potential to significantly improve stock trading efficiency by enabling transactions to settle almost immediately, instead of taking three or more days to clear each transaction.


Any person can access all data in the blockchain. Any changes are visible to the public. This is the reason that blockchain used in cryptocurrencies because every transaction is registered & displayed to the public.

Blockchain is the most cost-effective & efficient method to transfer money. As most of the information is available to the public, it results in giving more empowerment to users. Unlike typical databases, blockchains consist of every block of data from the start to just now.


Every day the blockchain records data as new transactions take place, the blockchain expands every moment and keeps getting bigger. Blockchain network needs nodes to run, old and renowned system have enough nodes to run their operation. Still, new blockchain faces the problem of lacking the number of sensor nodes to allow widespread use, and nodes also need an incentive for their network involvement.

Conclusion: Blockchain technology is growing with the passage of every day, and there are more possibilities for its use, that’s the reason it is a little difficult to discuss what is right and wrong about it.
