About Us
+
We are a team of 4, curious about blockchain technology. We started building this project under the
+ inheritance mentorship program at VJTI in September 2021.
+
About Blockchain
+
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. Each block in the chain contains a number of transactions, and
+ every time a new transaction occurs on the blockchain, a record of that transaction is added to every
+ participant’s ledger. The decentralised database managed by multiple participants is known as Distributed Ledger
+ Technology (DLT).
+
Blockchain is a type of DLT in which transactions are recorded with an immutable cryptographic signature called a
+ hash.
+
This means if one block in one chain was changed, it would be immediately apparent it had been tampered with. If
+ hackers wanted to corrupt a blockchain system, they would have to change every block in the chain, across all of
+ the distributed versions of the chain.
+
