At the moment of starting the search for a little deeper information on the operation of a Blockchain, perhaps at some point you will find information regarding the different layers that make up said network.
To contextualize a little more about this topic, it is necessary to know that within a current Blockchain there can be 3 types of layers that help improve the scope and scalability capabilities of a Cryptocurrency, in addition to the fact that in its most complex version it allows the creation of all kinds of decentralized applications. In this article we will explain the meaning of layer 1 of a Blockchain and why it is called this way.
When we talk about the layers that make up a Blockchain, it is inevitable to mention level 1 or layer 1, which is basically like the core of a chain of blocks, where all the information is stored, and through its encryption protocol it is in charge of the security of the stored data.
Let’s remember that all block chains are created or are born being layer 1 because this is the essential and minimum level for the operation of a Cryptocurrency. This is why it is very common to say that at level 1 of a Blockchain, Cryptocurrency transactions are created and executed, also through this protocol new units of said Crypto asset are created and thanks to it it can be protected from securely all information through encryption mechanisms.
As we mentioned earlier, a layer 1 network is another way of calling a base Blockchain. For example, the Ethereum (ETH) network or the original Bitcoin (BTC) network, which, like many others, 7layer 1 protocols.
All Blockchains are born with a layer 1 protocol embedded in them and a Blockchain cannot exist without this protocol, where basically all the functionalities of a Blockchain are the same functionalities of its layer 1.
Let us remember that not all Cryptocurrency networks are the same, for example the Bitcoin Blockchain is different from the Ethereum Blockchain, since the latter has very different characteristics and therefore level 1 of Ethereum is very different from level 1 of Bitcoin.
But even so, all the Blockchains of all the Cryptocurrencies have similar characteristics and some of them are essential to fit within the concept of a chain of blocks.
Below we will present the two most important Blockchain networks or those that opened the technological gap that arose in the use of digital assets as a means of payment:
Bitcoin – Capa 1
Being the first Cryptocurrency properly created, its development was essential for the beginning of what we know today as the economic system of Crypto assets, since it laid the foundations for the standard of all Blockchain networks with layer 1.
Satoshi Nakamoto practically created the standard of what a Blockchain must have to be a proper Blockchain, he was even the one who put together all the aforementioned fundamentals and developed the first block chain; Bitcoin may not be the best Blockchain in the world, but it is true that by being the forerunner of all current Blockchains, it left a great contribution within the Cryptocurrency ecosystem since many of the future digital currencies would be based on this model and would would improve, as is the case with our second largest Blockchain network.
Ethereum – Chapter 1
As we already know, Ethereum is the second most important Cryptocurrency in the Crypto market, but many do not know why. Apart from being an excellent Cryptocurrency with decent scalability at the time, Ethereum revolutionized the concept of Blockchain by adding some extra features that would allow incredible things to be done.
As we mentioned before, there are a series of characteristics that every Blockchain must have and that help to identify the layer 1 protocol.
In the case of Ethereum and many other Blockchains, it is very different since, although it is true that they have those characteristics mentioned above, they have also included some characteristics that make them unique, such as the creation of smart contracts and the inclusion of a powerful language. programming that allows improving the network and making it scale together using other layers such as layer 2 and 3.
These features were successfully implemented for the first time in Ethereum and, like Bitcoin, they were the basis for other future projects that also contributed their bit and improved the ecosystem of Crypto assets.
There are different layers because it is very difficult to achieve an integration of the different functions that the different layers of a Blockchain can execute and that in this way the transactional load of the operations executed in the chain of blocks can be better managed.
To identify if an operation or transaction is being executed within the first layer of a chain of blocks, it is as simple as verifying the protocol through which the transaction is operating. In general, all transactions generated in layer 1 are governed by all the rules. general chain of blocks and in the standardized times of said chain, if any of these characteristics change or are improved, it is most likely running on some other layer.
In theory, a Blockchain can have as many layers as necessary or a significant number, it all depends on how complex the code of said Blockchain has been developed, but currently it is common to see Blockchains with up to 3 application layers.
