So, today I want to give my thoughts on the development of the Kakarot project and how it might affect the crypto sphere as a whole:

Provable Transactions and Blocks
Kakarot zkEVM's ability to generate provable transactions and blocks based on the ZK-STARK proof system is a significant advancement. It ensures transaction and block validity can be verified on-chain, enhancing security and trust in the system.

EVM Compatibility and Interoperability
Kakarot allows developers to deploy Solidity or any EVM-compatible language smart contracts, similar to Ethereum or Polygon. This compatibility enables seamless interaction with existing EVM toolchains and promotes interoperability between different protocols.

Fractal Scaling
Kakarot zkEVM can exist as a smart contract on top of Starknet L2, providing an EVM interface on Starknet. Additionally, by combining Madara (a Starknet full node) and Kakarot, it becomes possible to create L3 zkEVMs, offering fractal scaling solutions. This allows for off-chain computation, reducing gas costs and improving performance while benefiting from Ethereum L1's security.

Decoupling Security and Decentralization
L3 zkEVMs, including Kakarot, offer the potential to decouple security and decentralization. Users can benefit from Ethereum L1's security while requiring a smaller number of validators, achieving a balance between security, scalability, and cost-effectiveness.

Gas Cost Reduction and Performance Improvement
Computing on L2 or L3 zkEVMs, such as Kakarot, significantly reduces gas costs compared to Ethereum L1. Furthermore, the scalability of rollups multiplies the performance (TPS), allowing for more efficient and cost-effective transaction processing.

Separation of Proof Verification and Data Availability
Kakarot zkEVM's integration with Starknet L2 enables the separation of proof verification and data availability. This allows for the utilization of new data availability solutions, potentially reducing costs further while maintaining security by posting both proofs and transaction data on Starknet.

Fusion of Kakarot and Madara
The combination of Kakarot and Madara into a unified stack opens up possibilities for type 1 zkEVMs. This would involve writing Ethereum consensus rules in Cairo within the Madara x Kakarot full node and implementing Keccak MPT, allowing Kakarot to prove L1 blocks. This advanced use-case depends on Ethereum's roadmap and developments, such as the adoption of the Verge and potential hash function changes.

Research Topics and Substrate Integration
The integration of Madara and Kakarot enables several research topics, including cross-rollup communication using Substrate's messaging protocol and the ability to innovate with consensus protocols. Additionally, Substrate's forkless runtime upgrades facilitate upgrading the EVM version used by Kakarot chains without requiring hard forks.

Kakarot's implementation of the zkEVM on Cairo and its integration with Madara and Starknet have the potential to significantly impact the future of Web3 and cryptocurrency. It offers provable transactions, EVM compatibility, scalability, and the ability to balance security, decentralization, and cost-effectiveness. Further advancements and research can potentially lead to type 1 zkEVMs and foster innovation in consensus protocols and upgrade mechanisms.
