Kroma Unveils New Secure Exclusive Validator Mechanism

• Kroma optimistic rollup based on the Superchain using zkEVM technology
• They introduced a new secure exclusive validator mechanism 
• KGH NFTs and $KRO token holders can now contribute to network security

Kroma, an optimistic rollup based on the Superchain using zkEVM, has introduced a unique validator mechanism supported by holders of Kroma Guardian House (KGH) NFTs and $KRO tokens.

How Does the Mechanism Work?

The validator mechanism provides $KRO-based incentives, allowing KGH NFT and $KRO holders to contribute to network security through delegation.

• Validator Prioritization. Validators are prioritized based on the number of $KRO tokens delegated to them. If a priority validator doesn't submit an output during the priority round, a public round opens for other validators.
• Bonding. Validators deposit $KRO tokens, which are partially bonded. If the tokens successfully pass the challenge phase, they are released, and validators receive rewards for their output submissions.

How Successful Is It?

Shortly, in the previous system, users could only participate in the validation process directly, which required technical knowledge and resources. The new mechanism allows tokens to be delegated to validators, simplifying the participation process for all users, including non-technical ones.

As a result, since Kroma's mainnet launch on September 5th last year, over 360 validators have registered, submitting more than 7,500 checkpoint outputs.

Conclusion

The new approach should make the Kroma network more accessible, resilient, and secure while reducing barriers for non-technical users to participate in validation.

Of course, any security solution presents a new target for attackers and takes time to prove itself.

However, security initiatives help develop other solutions, even if previous ones don't fully meet expectations, improving the industry anyway.
