Video Title: Merkle Tree In Blockchain | What Is The Merkle Tree In Blockchain | Merkle Tree | Simplilearn
Hey everyone i’m shamley and i welcome you all to this new video of simply learn on merkle tree in blockchain in this video at first we will see some of the use cases of merkle tree and then we will understand what is a merkle tree followed by what is a marble root
After which we will explore about cryptographic hash functions in blockchain and then we will understand how mongol tree exactly works after which we will discuss the benefits of mochal3 and at last we will explore why is it essential to blockchain so without much delay let’s get started with the video
But before starting let’s have a quick look at some general use cases of merkle tree of course there are more merkle trees implementations out there git a distributed version control system is one of the most widely used it is used to handle projects by programmers from all around the world
Interplanetary file system a peer-to-peer distributed protocol is another suitable implementation it’s also open source allowing computers to join and use a centralized file system merkle trees are used to benefit of certificate authorities as well it’s part of the technique that generates verifiable certificate transparency logs the final use case we’ll look at is
Database systems like amazon dynamodb and apache cassandra during the data replication process merkle trees are used by these no sql distributed databases to control discrepancies now the very first thing we will discuss is what is a mockultry merkle trees also defined as binary hash trees are a type of data structure
Commonly used in computer science merkle trees are used to encrypt blockchain data more effectively and securely in bitcoin and other cryptocurrencies it’s a mathematical data structure made up of hashes of various transactions of various data blocks in a particular blockchain network which acts as a summary of all the transactions in a block
It also enables quick and secure content verification across big data sets it also helps to verify the consistency and content of the data now that we know about the merkle tree let’s explore what is a merkle root a merkle root is a simple mathematical method for confirming the facts on a mogul tree
They are used in cryptocurrency to ensure that data blocks sent through a peer-to-peer network are whole undamaged and unaltered muggle roots play a crucial role in the computation required to keep cryptocurrencies like bitcoin and ether running now that we know hash is a big part of
Mughal tree let’s dive down and have a look at some of the cryptographic hash functions a hash function maps any type of arbitrary data of any length to a fixed size output it is commonly used in cryptography since it is a cryptographic hash function the hash functions are efficiently
Known for one property they can’t be reversed it’s a one-way function that’s only meant to work in one direction message direct secure hash function and ripe message direct are some of the hash families available now let’s take an example if you use the sha 256 hash algorithm and pass 101 blockchains as input
You will get the following output this concludes that hash functions have the following key properties deterministic pre-image resistant computationally efficient cannot be reversed engineered and collision resistant now that we know about various aspects of the merkle tree let’s understand how the mercury works now that we have a basic understanding
Of hash functions we can move on to the working of mobile trees a merkle tree totals all transaction in a block and generates a digital fingerprint of the entire set of operations allowing the user to verify whether a transaction is included in the block merkle trees are made by hashing pairs
Of nodes repeatedly until only one hash remains this hash is known as the merkle root or the root hash they are built from the bottom using transaction ids which are hashes of individual transactions each non-leaf node is a hash of its previous hash and every leaf node is a
Hash of transactional data of each block here’s the example of a mokul tree to help you understand the concept consider the following scenario a b c and d are four transactions all executed on the same block each transaction is then hashed leaving us with hash a hash b hash c and hash d
Now the hashes are paired together resulting in hash a b and hash cd a mogul root is formed by combining these two hashes hash a b c d in reality a merkle tree is much more complicated especially when each transaction id is 64 characters long but this should give you a good concept
Of how the algorithms work and why they are so effective now let’s explore the benefits of mogul tree merkle trees provide four significant advantages validate the data’s integrity it can be used to effectively validate the data’s integrity takes little disk space when compared to other data structures the mogul tree takes up very
Little disk space timely information across networks muggle trees can be broken down into small pieces of data for verification and efficient verification the data format is efficient and verifying the data’s integrity takes only a few moments now that we know the benefits of murkle free let’s explore how it is essential to blockchain
Let’s imagine a blockchain without mercury to get a sense of how vital they are for blockchain technology we’ll focus on bitcoin because it’s use of mongol trees is not only important for the cryptocurrency but also simple to grasp if bitcoin didn’t include morgle trees for example every node on the mob
Network would have to retain a complete copy of every single bitcoin transaction ever made you can imagine how much information that would be any authentication request on bitcoin would require an enormous amount of data to be transferred on the over the network therefore you’ll need to validate the data on your own
To confirm that there were no modifications a computer used for validation would need a lot of computing power to compare ledgers well merkel tree are a solution to this issue they hash records and accounting thereby separating the proof of data from the data itself proving that giving tiny amounts of information across the
Network is all that is required for a transaction to be valid furthermore it enables you to demonstrate that both ledger variations are identical in terms of nominal computer power and network bandwidth well that is all about mercury we have almost reached the end of this video if

This is just read out. Not very helpful
Good explanation, however you missed one case:
If the count of leaf nodes are odd in number then last node is grouped (repeated) with itself to form a pair
GOOD!!!
Ngl worst explanation ever.. boring !!!!!!
4:43 best diagram ever
Very interesting topic! Thank you for the clear explanation!
Grt Video
Awesome ❤
