Do you know what is a blockchain...?

[book1483]

It is something in which all the transactions that happens goes through.

The blockchain stores all the transactions, and groups them into blocks. Each block is linked(chained) together through hash functions.
That is why it is call blockchain.

Note that Satoshi Nakamoto does not use the term blockchain in his Bitcoin whitepaper at all. Blockchain is a term later given to the way Bitcoin transactions were being stored. This idea of linking data together through hash functions was first described in a paper from the early 90s. In fact this paper is one of Satoshi Nakamoto's sources he sites in his Bitcoin whitepaper.

blockchain technology

Technology that allows no central party to verify transactions. You need huge distributed calculated power to achieve that.
Most people forget that and talking about blockchain while its not it

I want to know whether what is a blockchain technology...? If you know, please explain as simple as possible.... 

As far as I know, blockchain is considered as a decentralized, peer-to-peer transaction. Using this technology, participants can transact without the need for a centralized authentication unit. Potential applications for blockchain applications are money transfer, trade, election, and more.

The blockchain is a ledger that records all transactions. Blockchain technology has many other uses where Bitcoin currency is just one of them. The blockchain technology platform allows strangers to trade safely without mutual trust.
In addition, blockchain technology opens up a potential application trend for many areas such as banking and finance, retail, transportation, manufacturing, telecommunications ...

Blockchain is a public-registry technology that uses digital signatures and cryptographic hashes to provide records of secure transactions that can not be changed.

I've found what is most useful is checking youtube videos to answer all your beginner questions.

Hey,
In one word it just a wallet to hold bitcoin. It just a ledger where all transaction history stored of your bitcoin wallet.

You can understand Blockchain is a technology that allows secure data transmission based on extremely complex coding systems. The Blockchain system is divided into three categories:
-Public: Anyone has the right to read and write data on Blockchain. Authentication process on this blockchain requires thousands or tens of thousands of participants. Therefore, it is impossible to attack the Blockchain system because of its high cost.
-Private: The user is allowed to read the data, not write permission, because it belongs to the third party trusted.
-Permissioned: Also known as the Consortium, a form of Private but augmented with certain features, combining "trust" with public participation and "absolute trust" when joining Private.

The blockchain is the technology behind Bitcoin and allows digital money like Bitcoin to work. Blockchain specifically promotes its strength in managing and trading all types of online assets that are most commonly present in copper bitcoins.

The blockchain is a technology that allows secure data transmission based on the encryption system. Blockchain possesses a very special feature that the transmission of data does not require an intermediary to confirm the information.

[kjfngkleoi]

Blockchain or the ledger, its original name is a blockchain, is a database system of information, which is used to store information in linked blocks, and is managed by Everyone participates in the system, instead of a separate third parties such as the state or the central bank; It also allows for secure data transmission with a complex encryption system, and is scalable over time.

It's a series of keys that record the entire set of keys

[lamroinhau09]

The blockchain is an information database system used to store information in linked blocks and is managed by all participants in the system, not the third party such as the government or the bank. It also enables secure data transmission with a complex and extended encryption system over time.

All data on the Internet is easily copied. As we know, Bitcoin is just one application of Blockchain technology, meaning that each Bitcoin transaction is just one file.
Normally, when dealing online, we will need a third party that we trust (eg, intermediary, shipping company, bank ...) with a database set to verify the transaction to prevent fraud when the crooks use this file repeatedly.
Blockchain technology solves this problem without the need for a reliable third party.
The blockchain is a ledger that records all transactions

The blockchain is a technology that securely transfers data based on a very complex coding system, similar to a company's accounting ledger, where cash is closely monitored.

[macarong998]

Blockchain technology is similar to a database, just different in interacting with a database. To understand blockchain, it is important to understand the following five definitions: block chaining, distributed consensus mechanisms, reliable computing, intelligent contracts, and work proof. This computational model is the basis for creating distributed applications.

[draacubile328]

Technically, blockchain provides a hierarchical data called "digital ledger" and uses encryption technologies. Everyone can see their transactions. This network is basically a series of computers that all have to approve a transaction before it can be validated and recorded. It's like sending a letter and everyone confirms the letter is yours. Your letter will be sent to various computers and confirmed, the contents of the letter will be scattered and re-entered into a matching string.

[suchi2591]

In a very simple language: It is a kind of data structure which stores information about crypto transaction.

[shade jenn]

Blockchain is one technology that does not use third parties in the data exchange process or in the transaction process.

The example is, if you buy something in the store by using a debit card, the third parties here are banks that connecting the buyers and sellers in the transaction using the debit card. But in the bitcoin, seller and buyer can be directly connected without third parties assistance.
