What are the different second layer solutions? Understand modular blocks – Money Times

You block chains modular solutions seek to use second-layer scalability solutions or so-called 2nd layer (L2) solutions.

These technologies allow transactions in a particular blockchain to be validated in parallel, connected to the original, or even in a fragmented version.

Once the transactions are validated, a “summary” that takes up less space is sent to or stored in the main blockchain.

The advantage of this is the greater scalability of this network, which means that the amount of “work” – or validation – given to the original is shared and distributed between these layers, allowing for greater volume.

As a result, the speed is higher and therefore the network rates are lower.

There are different types of secondary solutions, and it is important to understand a little about them:

It is a secondary solution where the transaction is performed outside the main block chain or outside the primary chain.

When the transaction is complete, the data is taken and placed in layer 1. When the transaction data is in layer 1, it checks the rollups and sets the main blockchain “stones”.

There are currently two rollup models: so-called zero knowledge (Zk Rollups) and optimistic (Optimistic Rollups).

Zero Knowledge Rollups performs external chain validations and send proof of that validation to the main lock chain.

On the other hand, Optimistic Rollups assumes that all transactions are valid, and only validate this validation if there is a proposed challenge.

The challenge is through a method called “proof of fraud”.

In short, rollups are blockchains created for various transactions that take place outside of the original. It makes it easier to imagine it as a branch of the main blockchain, where each branch is tied to a single tree.

All branches are tied together and depend on the tree. Each branch supports a number of fruits (transactions). The more branches, the more fruit (transaction) the tree supports.

Sidechains have different features from Rollup.

For example, they are independent working in parallel with the main one and are free to function as a decoupled block chain, so it can have its own behavior and attributes.

These secondary blocks have their own consensus algorithms, such as Proof-of-Work, Proof-of-Stake, and so on.

They also communicate with the main blockchain network via a two-way bridge or a two-way pin (TWP).

The TWP protocol used by Sidechain allows the transfer of cryptocurrencies from the main blockchain to a 2nd layer block.

However, this process requires a third validation to function, where the first two validations will refer to transactions within the blocks – and independent – (first and second layers), and the third would validate the transaction between them.

Sharding solutions involve splitting the network into different parts or parts called parts. These parts of the main blockchain are responsible for certain tasks (transaction, validation, etc.)

The secondary solution ultimately helps the network to organize its ability to scale transactions.

Sharding seeks to extend the weight of tasks across the network, thereby bringing more computing power to more validator nodes, which ultimately aims to help ease the process of creating new blocks.

However, this model has some weaknesses in terms of network security.

Once the main parts of the blockchain, the parts can be attacked, so this problem is something to be aware of.

The upgrading of the Ethereum network, scheduled for June 2022, will specifically apply the concept of division, while other second-tier solutions will continue to function as a solution at the same time (such as Polygon’s Sidechain).

Parachains are used and popularized by Polkadot (DOT). Polkadot Layer 0 is a blockchain.

This means that other blockchains can be built “on top” (and are already being built).

Block chains built on top of Polkadot are called “parachutes” and use Polkadot security and validation.

Developers can take the convenience of building a custom layer 1 block chain, and layer 0 (Polkadot) ensures network security and scalability.

The Polkadot network began putting its parachutes on the network this year, and the renewal of the Ethereum network is scheduled for the third quarter of 2022.
