Terms Related Blockchain BTC!

Blockchain's institutional adoption is more like bitcoin, as from being a core technology of bitcoin, people now recognize blockchain as the underlying technology of decentralized finance.

Moreover, blockchain incurs numerous attributes like immutability and decentralization.

However, if you are interested in bitcoin trading, you can start using a reliable website.

But newbies fail to see the potential of blockchain because of its mysterious nature.

To put things in perspective, blockchain could be the second "Internet" for global financial transactions.

From 1998 to 2016, the bitcoin price increased from US$0.000008 to 50000 USD in 2021.

During this period, bitcoin market capitalization has grown from US$0.55 billion to 890 billion USD in 2017.

Experts discuss the applications of blockchain in various domains for entrepreneurs and investors to understand it better and it's potential as a transformational technology.

Here are some famous terms related to the blockchain of bitcoin.

1. Block:

The block is of data weight of 1MB and a reward of 6.25 BTC per block.

The data in a block is cryptographically linked with previous blocks; therefore, tampering with one block would require an attacker to recalculate all the other blocks.

2. Mining:

Mining has become synonymous with bitcoin because it is how new bitcoins are created as rewards for maintaining network security by verifying transactions and generating them in the first place.

A peer-to-peer network with every node is responsible for updating information in the blockchain.

As a result, all transactions are confirmed through mining. Mining is done by devoting computing power to solving complex mathematical problems.

The process of mining helps in creating new bitcoins.

3. Proof of Work:

The "proof of work" is used to establish the validity of transactions, and it's also used to create new coins like Bitcoin, Ethereum, etc.

Moreover, it prevents spam and attacks on the network because it requires enormous computational work.

It will be very costly and time-consuming to generate fraudulent transaction histories or steal existing funds or data stored in the blockchain.

Anyone looking to alter the blockchain must redo the proof-of-work of all subsequent blocks and their ancestors.

Every 10 minutes, on average, a new block is appended to the blockchain through mining which adds a transaction and a random "Nonce" whose value depends on recent hashes.

4. Hashing Function:

The hash function is the reason behind the secure nature of bitcoin.

The hashing function makes it much harder for an individual or organization to "tamper with" transaction information in a block and creates an added layer of security by introducing additional complexity in the proof-of-work formula (Complexity = Nonce x SHA256).

Currently, there are two popular hashing functions, i.e., SHA256 and Scrypt.

5. Nonce:

The Nonce is nothing but a random set of numbers added to the hashed value of the block by miners to result in a new hash value that meets the given difficulty target of the proof-of-work algorithm.

The difficulty target for Bitcoin's SHA-256 is adjusted based on how fast new blocks are added to the network to keep the rate at 10 minutes between blocks in normal circumstances.

6. Merkle Tree:

The Merkle tree is built with cryptographic hashes, each node representing a different level of authentication and data organization (in cryptography or computer science).

It is a binary tree or a tree in Abstract Digital Logic (ADL) where each node contains the hash from the previous level.

The root hash is called Merkle root.

7. Merkle Proof:

The Merkle proof is created via a system of hashes and timestamps that show all transactions for a particular account on the blockchain and their position in the blockchain.

Any node on the network can verify unique transactions grouped by the nearest block header.

8. Double Spending:

Double Spend is the act of spending the same Bitcoin (BTC) on two different transactions, where one transaction is recorded in a block, and another has been spent by someone else.

If you make a double spend, your entire balance will go to a Bitcoin address belonging to someone else.

9. UTXO:

UTXO is unspent transaction outputs that remain available through some form of storage or verification rather than remaining permanently locked up in a transaction output that can only be spent once.

They are essentially an array of keys (txid) and public keys (address).

This data structure can prove the existence of Bitcoin addresses and thus facilitate communication between machines.

10. Hashcash:

Hashcash is a purely cryptographic proof-of-work (PoW) system that had an addition to Bitcoin in the early days of the cryptocurrency.

Hashcash is used to deny service to users who provide computational power to verify transactions and prevent double-spending.

11. Mining Difficulty:

The difficulty target is set to make mining difficult.

The target achieves it by having a slow block time and requiring more work from mining pools to generate enough blocks per hour.

The difficulty must adjust dynamically like other currencies or assets that decrease or increase in value over time.
