Blockchain is a system of recording information in a way that makes it difficult or impossible to change, hack, or cheat the system. A blockchain is essentially a digital ledger of transactions that is duplicated and distributed across the entire network of computer systems on the blockchain.
How do you explain blockchain to a child?
The simplest definition of blockchain suggests that it is a decentralized public ledger that helps in recording all transactions throughout multiple computers. One of the biggest highlights of blockchain technology is that the network does not have any central point.
What is blockchain in one word?
A blockchain is a decentralized, distributed, and often public, digital ledger consisting of records called blocks that are used to record transactions across many computers so that any involved block cannot be altered retroactively, without the alteration of all subsequent blocks.
What is a blockchain and how does it work?
A blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.”

What is an example of blockchain?
Bitcoin and Ethereum are popular examples of blockchains. Everyone is allowed to connect to the blockchain and transact on them.
How would you describe what blockchain is to a 5 year old?
Blockchain is basically a network of computers called nodes which all have same history of transactions. So instead of one company or a database which holds all the information, now the information is spread across whole of the network.
Why do we need blockchain?
Blockchain helps in the verification and traceability of multistep transactions needing verification and traceability. It can provide secure transactions, reduce compliance costs, and speed up data transfer processing. Blockchain technology can help contract management and audit the origin of a product.
Why is it called blockchain?
Why is it Called “Blockchain”? Blockchain owes its name to how it works and the manner in which it stores data, namely that the information is packaged into blocks, which link to form a chain with other blocks of similar information.
What is blockchain good for?
Blockchain helps in the verification and traceability of multistep transactions needing verification and traceability. It can provide secure transactions, reduce compliance costs, and speed up data transfer processing. Blockchain technology can help contract management and audit the origin of a product.

Where is blockchain used in real life?
Blockchain in Money Transfer Blockchain is especially popular in finance for the money and time it can save financial companies of all sizes. By eliminating bureaucratic red tape, making ledger systems real-time and reducing third-party fees, blockchain can save the largest banks lots of money.
How many Blockchains are there in the world?
Currently, there are at least 1,000 blockchains with at least four types of blockchain networks. While the idea of blockchain is a singular data transfer type, there are multiple platforms provided in this industry.
Where is blockchain data stored?
The blockchain is stored on computers in a network called nodes. The data itself is stored on a user’s hard drive. It can also be stored on a virtual server on a cloud computing network. Using cloud storage adds a layer of security for the blockchain, with the added benefit of remote access.
How does blockchain work in cryptocurrency?
A blockchain is a decentralized ledger of all transactions across a peer-to-peer network. Using this technology, participants can confirm transactions without a need for a central clearing authority.
What are disadvantages of blockchain?
One of the main disadvantages of blockchain technology is the immutability of data. It benefits financial and supplies chain systems. Immutability can only exist if network nodes are fairly distributed. A blockchain network is vulnerable if one entity owns at least half the nodes.
How will blockchain change the world?
Banks are also eager to adopt digital tokens for a huge transfer amount of money. It generally helps them to do bank to bank settlements faster and securely. Therefore, blockchain technology could change the world by offering a faster transaction process.
Who invented blockchain technology?
Blockchain has the potential to grow to be a bedrock of the worldwide record-keeping systems, but was launched just 10 years ago. It was created by the unknown persons behind the online cash currency bitcoin, under the pseudonym of Satoshi Nakamoto.
Is blockchain on the Internet?
Blockchain is a decentralized trust mechanism that is opposite to the Internet. Blockchain will give rise to a distributed business model that is open source, free, license-free and non-profit. Finally, the blockchain adopts distributed ledger, which is different from the centralized ledger of the Internet.
Can blockchain be hacked?
The concepts behind blockchain technology make it nearly impossible to hack into a blockchain. However, there are weaknesses outside of the blockchain that create opportunities for thieves. Hackers can gain access to cryptocurrency owners’ cryptocurrency wallets and exchange accounts to steal crypto.
Does every crypto have its own blockchain?
Coins are built on their own blockchain and were originally intended as a form of currency. Generally, any blockchain-based cryptocurrency that is not Bitcoin is referred to as an altcoin (more on those below). A digital coin is created on its own blockchain and acts much like fiat (traditional money).
