### AVS Description

Witness Chain AVS employs a decentralized watchtower network to enhance the security and reliability of optimistic rollups and decentralized physical infrastructure networks (DePINs). Using Proof-of-Diligence (PoD), it incentivizes watchtowers to maintain vigilant oversight of transaction verifications. Witness Chains' approach deters fraud by ensuring consistent watchtower performance but also decentralizes and automates the fraud detection process, reducing reliance on after-the-fact validator interventions.


### Unique Selling Proposition

Watchtower protocol integrates PoD mechanism that is designed to verify L2 state claims on L1. By unique incentivization of validators, Witness Chain ensures more robust and proactive fraud detection, addressing a critical gap in existing blockchain security practices. As the first physical state consensus protocol, Witness Chain unifies DePINs, enabling a shared economy that optimizes resource allocation and fosters innovation across various sectors. Integrating with Witness Chain offers several compelling benefits for DePIN chains: enhanced discoverability and economic growth by facilitating the creation of new services and bundled offerings, real-time visibility into available resources, reducing wastage and improving operational efficiency, and access to comprehensive state information enables app builders to develop innovative services and improve existing ones .

### Centralization

The [AVS contract](https://etherscan.io/address/0xd25c2c5802198cb8541987b73a8db4c9bcae5cc7) is owned by [multisig](https://etherscan.io/address/0xec6D5f54dC69EBed2379470303B706491E9E80f3) with four signatories:
[0xa7ec0a5A7798e1480224F878863A4E24b5473945]
[0x96521196855D19C56A35301A014cF99455b0F221]

The current Withness Chain documentation does not disclose the identities or affiliations of these multisig participants.

### Security

The [audit conducted by Dedaub](https://github.com/witnesschain-com/diligencewatchtower-contracts/blob/main/audits/Witness%20Chain%20Report%20-%20Mar'24.pdf) on Witness Chain's AVS contracts in March 2024 resulted in no findings of high or critical severity issues. Medium and low severity issues were either acknowledged or resolved.

### Maturity

Mainnet date: April 11th, 2024
Goerli date: December 16th, 2023
Sepolia date: January 24th, 2024

[Watchtower-contracts](https://github.com/witnesschain-com/diligencewatchtower-contracts) repo had a single boost of commits pre-mainnet launch, followed by a long period of inactivity. [Watchtower-client](https://github.com/witnesschain-com/diligencewatchtower-client) repository is much more active with regular commits to date.

### Regulatory Complexity

Low risk of legal challenges is anticipated for the project, rooted in its infrastructural nature, which positions it to be regulatory agnostic. 

### Risk Considerations

- Admin rights are centralized under a multisig wallet, controlled by four signatories whose identities remain undisclosed;
- The absence of a clearly communicated economic model undermines the ability of operators and re-stakers to effectively assess the risk-reward dynamics and engage in sound financial planning. This lack of transparency hinders their capability to anticipate returns, understand the types of tokens utilized, and the conditions attached to allocations.
