Data availability unlock with ZK-Rollup: Why ZK-CRP provides unparalleled security
The concept of zero knowledge evidence (ZKP) has long considered a safe way to prove the correctness of the calculation without disclosing any sensitive information. However, in the context of ZK-Rolup, this seemingly paradoxical approach raises an important question: Why does ZKRP mechanisms like ZK-CRP provide data availability? In this article, we will study the intersection of the ZKP and ZK-Rollups, emphasizing the benefits and limitations of both approaches.
ZKP paradox
The basic principle of the CCP is to prove that the statement is true without disclosing any information about the entrances or exits. This can be achieved through a variety of techniques such as commitment schemes, zero knowledge evidence and hash -based evidence. However, this characteristic secret requirement is related to catch: if you want to save certain information private, you also need to carefully choose your protocol.
ZK-CRP: Proof of correctness without disclosure
The ZK-CRP is a type of zero knowledge evidence that includes the use of a relationship scheme and hash functions to prove that the statement is true. The basic idea is to commit to the input \ (x \) using a private key and then this determined value as an entrance to another calculation. This calculation produces a result \ (y \) that can be used to check the original obligation.
The essence of the ZK-CRP lies in the fact that it provides a way to prove correctness without disclosing any information about inputs or exits. Using the hash function to calculate the output from a determined entrance, you can prove that the original entrance was really correct.
ZK-Rollups: Combination ZKP and ZK-SNARK
ZK-Rollup is a blockchain class that uses Rollup protocols to handle several transactions in parallel. These protocols usually include the use of commitment schemes, such as zero knowledge evidence (ZKP) and hash -based obligations to ensure data availability.
In the traditional ZK Protocol, the user’s private keys are used to make values for a storage agreement or other storage layer. The calculation is then made with these determined values to obtain the output. This process, however, can be or as a series of steps:
- Commitment: The user shares his / her input \ (X \) with a reliable side.
Hash Function: Hash Function calculates output \ (y \) based on the determined value and the user’s private key.
3rd output: The user receives the calculated value \ (Y \), which can be used to verify the correctness of the initial obligation.
ZK-Rollups are performed using ZKP methods such as ZK-CRP or similar protocols that allow users to prove correctness by detecting any sensitive information. This is achieved using a private key and hash function to calculate the output from the determined value.
Data availability zk-rollups
Now that we have investigated why ZK-CRP provides data availability in the ZK-Rollup context, let’s check how it works:
* Liability based : When the user makes their input \ (x \) using a private key, they share a commitment to the Rollup Protocol.
Hash function based : Hash function calculates the output value \ (y \) based on the determined value and the user’s private key. This output is then used to ensure the availability of data in the blockchain.
Provenance of correctness without information : Users can prove that their input was really correct without disclosing sensitive information.
ZKP Restrictions
While the ZKP provides an effective way to prove correctness without disclosing sensitive information, there are limitations:
* Scalability : Power ZKP protocols can be slow and ineffective for large -scale transactions.
* Compatibility
: The ZKP might not be compatible with existing blockchain architectures or protocols.
