Discover the intricacies of Tezos Smart Rollups, their benefits, and unique features like being optimistic and enshrined, according to Tezos Spotlight.
Tezos is making waves in the blockchain space with the introduction of Smart Rollups, a Layer 2 scaling solution designed to significantly increase transaction capacity. According to Tezos Spotlight, these rollups move computation from Layer 1 to a dedicated infrastructure, enhancing efficiency and performance.
What are Tezos Smart Rollups?
Tezos Smart Rollups are a Layer 2 solution that optimizes transaction throughput by processing computations off-chain and committing the results periodically to the Layer 1 blockchain. This innovative approach allows for a substantial increase in transaction capacity. Notably, Tezos Smart Rollups are optimistic and enshrined within the protocol, offering both public and private configurations.
Rollups Explained
Rollups are a method to scale blockchain computations while maintaining the security guarantees of the main blockchain. By executing computations off-chain and summarizing the results on-chain, rollups can drastically enhance transaction throughput. For example, Tezos developers have demonstrated the capability to achieve one million transactions per second using rollup technology.
Optimistic Rollups
Tezos Smart Rollups are categorized as optimistic rollups. In this system, any participant can post a commitment to the Layer 1 blockchain, which is considered valid unless challenged within a specific period. Users are responsible for verifying commitments and providing fraud proofs if necessary. If fraud is detected, the challenger is rewarded, and the fraudulent party loses their staked tokens. This mechanism ensures that only one honest node is required to maintain the rollup's integrity.
Enshrined Rollups
Being enshrined means that Tezos Smart Rollups are integrated into the protocol as first-class citizens. This integration allows the Layer 1 protocol to offer common infrastructure to all rollups, such as a message inbox and refutation game logic. Developers can deploy and manage Smart Rollups more easily and securely, without needing to rebuild the infrastructure from scratch. The open-source nature of the Tezos protocol ensures transparency and community governance over any changes to the rollup management logic.
Public vs Private Rollups
Tezos supports both public and private Smart Rollups. Public rollups are permissionless, allowing anyone to participate as an operator and contribute to the rollup's security. In contrast, private rollups are permissioned, limiting the set of operators to those approved by the rollup originator. This feature is beneficial for scenarios requiring state protection. While private rollups can be transitioned to public, the reverse is not possible.
For those interested in deploying a Smart Rollup on Tezos, the Tezos documentation provides a comprehensive guide.
