As you know, whenever there is a need to change or update in the field of a specific cryptocurrency, this update and in other words, updates must be notified to all users. Some cryptocurrencies even use feedback from their core users for future updates. In such a situation, the developers announce that buyers must update their wallets in line with these changes and updates, which in some cases will cause a hard fork to happen.
Normally, digital currencies are always being updated and updated. Buyers know ahead of time that many updates will happen in the future that may have a big impact on the market and prices. As a result, forks happen in many cases in the cryptocurrency network. But when will these changes be successful?
The applications of blockchain in various industries are becoming bolder every day, and we need to expand our knowledge in this field. If we want to simulate the block in simple language, we can consider it like a ledger that gives place to the next block as each block is completed. Also, the information inside the blocks cannot be deleted or changed. The entire blockchain is exactly similar to a ring and the blockchain system should be considered a chain. Therefore, each blockchain has thousands of blocks, and this small item causes a very high level of security in the network; Because it becomes practically impossible to hack the block.
One of the important questions that are often asked by cryptocurrency activists is the desired height of each block. This height depends on the data of each block and it is not possible to specify a fixed height for each block. The height of the block is recorded in the blockchain system and only the nodes in the entire network can be traced. Each block has a time tag to maintain the consistency and integrity of the entire system, that is, the production time of each block is determined based on its height and amount of data.
So far, you have understood that blocks are a set of links in a chain with high security, each of which is used for different transactions. Each transaction is recorded in a block at a specific time and the collection of these activities makes the blockchain.
Each block contains data and information, and each time it is completed, it gives its place to the next block. With the arrival of the new block, all future transactions must be done in the new block and will no longer be valid in the old block. This function has caused this blockchain system to be called “action chain”. In fact, the whole system is a cycle and has data that defines the height of the block.
The field of cryptocurrencies is full of terms that must be learned in order to enter the cryptocurrency world. Concepts such as the root of the Merkel tree, hardness, Nance, and Oracle are among these specialized concepts that you must familiarize yourself with in order to understand the height of the block. In the following, we briefly explain these terms:
All block transactions are collected in a hash that is in the block header. This hash, which is the place where the transaction history is stored, is the root of the Merkel tree.
Difficulty is actually the number of zeros that appear in the Bitcoin block header during hashing.
Nonce is a type of variable that increases if the work is proven. The value of the nonce is changed by the miners in a specialized way to achieve the difficulty or the number of zeros of the hashing time.
Oracle is one of the most important and fundamental foundations of the blockchain world, which plays an essential role in determining how to respond to the user. Oracle is responsible for data and information exchange and has a very strict process for communicating with smart contracts.
So until now, you have realized that blockchain is a chain of different blocks that are introduced and created by miners. Each block consists of a body and a header and carries important information of the transaction history attack. The security of this information must be well maintained, and most importantly, it is this information and data that determines the height of each block. Each cryptocurrency has its own specific block that enters the network at specific time intervals.
