AltLayer: The Three-Tiered Approach to Security for Web3

The world of Web3 is quickly evolving, and with it comes the need for more secure and efficient solutions. One such solution is AltLayer, a hyper-scalable and disposable execution layer that provides a three-tiered approach to security.

AltLayer offers a unique approach to security that caters to users with varying security budgets. In this article, we will explore the three tiers of security that AltLayer provides and how they make it an ideal solution for Web3.

Low Budget Security

The first tier of security is designed for users with a low budget for security. AltLayer achieves this by having multiple block producers that reach consensus on the next block, thus avoiding a single point of failure and mitigating any censorship from a malicious sequencer. A user with a low security budget may decide to accept a block as soon as at least one honest block producer generates the correct block.

Medium Budget Security

The second tier of security is designed for users with a medium security budget. Once a block is produced, verifiers in AltLayer check the validity of the block. Verifiers re-execute transactions and compare the generated state root with the Merkle root committed by the block producers. Verifiers are also required to commit data to the underlying Layer 1. A user with medium security budget may decide to wait until a given block is verified by at least one verifier. Note that a verifier can be run on different platforms, e.g., commodity x86/ARM machines, web browsers, dApp backends or hardware-assisted environments.

High Budget Security

The third tier of security is designed for users with a high security budget. As AltLayer ultimately derives security from the underlying Layer 1, a user with a high security budget may decide to wait until the FlashLayer is disposed of and when the dApp state gets rolled up to Layer 1. At this stage, the security achieved is the same as that of the sovereign Layer 1.


AltLayer’s three-tiered approach to security makes it an ideal solution for Web3. It offers a range of options for users with varying security budgets, and its modular design allows for easy integration with any Layer 1 or Layer 2. With AltLayer, developers can build more secure and efficient Web3 applications, and users can enjoy a higher level of security and peace of mind. As the Web3 ecosystem continues to grow, solutions like AltLayer will play a critical role in ensuring the security and success of the platform.
