zkTube Combination of Zero Knowledge Protocol and Layer2 (Part 1)
Introduce
Layer 2 is a generic term for solutions designed to help scale your application by processing transactions beyond the Ethereum mainnet (layer 1), while leveraging a strong decentralized security model. strength of the main network. Transaction speeds suffer when the network is busy, which can result in poor user experience for some types of dapps. And as the network gets busier, gas prices rise as transaction senders aim to outbid each other. This can make it very expensive to use Ethereum.
You should have a good understanding of all fundamental topics and a high level understanding of Ethereum scale. Implementing scaling solutions like roll-up is an advanced topic as the technology is less combat-tested and under ongoing research and development.
WHY GRADE 2 NEEDED ?
- Some use-cases, like blockchain games, make no sense with current transaction times
- It can be unnecessarily expensive to use blockchain applications
- Any updates to scalability should not be at the expense of decentralization or security — layer 2 builds on top of Ethereum.
ROLLUPS
Rollups are solutions that perform transaction execution outside the main Ethereum chain (layer 1), but post transaction data on layer 1. As transaction data is on layer 1, this allows rollups to be secured by layer 1. Inheriting the security properties of layer 1, while performing execution outside of layer 1, is a defining characteristic of rollups.
Three simplified properties of rollups are:
- transaction execution outside layer 1
- data or proof of transactions is on layer 1
- a rollup smart contract in layer 1 that can enforce correct transaction execution on layer 2 by using the transaction data on layer 1
Rollups require “operators” to stake a bond in the rollup contract. This incentivises operators to verify and execute transactions correctly.
Useful for:
- reducing fees for users
- open participation
- fast transaction throughput
There are two types of rollups with different security models:
- Zero knowledge rollups: runs computation off-chain and submits a validity proof to the chain
- Optimistic rollups: assumes transactions are valid by default and only runs computation, via a fraud proof, in the event of a challenge
What is ZK (zero-knowledge) synthesis?
One of the biggest challenges of many blockchains is scalability, or in other words making transactions fast and cheap. Low scalability prevents the network from growing and gives developers a reason to look for another blockchain.
The Ethereum blockchain, for example, has had a scalability problem for years. Crushed under the weight of its own success, the network is now running at around 15 transactions per second, while a single transaction can cost upwards of $20.
ZK-Rollups, or in complete no-knowledge, can provide a scalable solution.
ZK-Rollups is a layer 2 scaling solution. It is a solution that is not integrated into the underlying blockchain architecture, but exists as a second layer above it.
With this solution, funds are held by a smart contract in the main blockchain (layer 1) while computations and storage are done off-chain (off-chain) and/or on the side chain second (grade 2). The roll-up thus relieves the pressure on the main blockchain by reallocating some transaction processing responsibilities to another blockchain.
Zero-knowledge proofs guarantee the validity and reliability of these side chains. ZK proofs reduce the computing power and storage required to validate blocks by reducing the amount of data stored in a transaction. No need for full data knowledge, a few intermediate checks can validate an entire block.
In that sense, you can compare them to the Bitcoin lightning network
It’s called “roll up” because the technology rolls back transactions and fits into a block. This frees the network from congestion, making transactions faster and cheaper.
Conclude
With the content that I give, you probably have a better view of Zero Knowledge Protocol and Layer2. The existence of Layer 2 scaling solutions relieves pressure from the main chain. This benefits gas prices for traders on both sides, reducing transaction fees for everyone. It is important to note that roll-up is a complex and experimental technology. The ZkTube team is doing their best to prepare the test network to go live. It is receiving great attention from users. The test system has been running since April 27, so far everything is great. In the next section I will go into detail about this project, maybe you will realize a great investment opportunity
