Yes, you can stake tokens in the Celestia project. Here’s a breakdown:

• Token to Stake: The native token used for staking is TIA, with the staking denomination being "utia", which is equivalent to micro TIA (1 TIA = 1,000,000 utia) [source].
• Staking Process:
  • Celestia operates as a proof-of-stake blockchain based on the Cosmos SDK.
  • Users can either become validators by meeting hardware requirements and staking TIA, or they can delegate TIA to existing validators [source].
  • Validators and delegators secure the network and participate in consensus [source].
  • Validators gain active status based on the amount of TIA staked/delegated, earning rewards if they are among the top validators [source].
• Rewards:
  • Validators earn rewards consisting of inflationary emissions and network transaction fees, both denominated in TIA.
  • Delegators receive a pro-rata share of the block rewards minus the validator’s chosen commission rate.
  • Currently, staking yields are estimated to be between 15% to 17% annually [source].
• Additional Benefits: TIA stakers might also be eligible for airdrops from projects using the Celestia infrastructure [source].

Staking TIA not only secures the network but also offers an opportunity to participate in network governance and gain financial incentives through rewards and potential airdrops.

Based on recent data search, there have been no notable hacks, exploits, or outages reported for the Celestia project's native protocol or network where a significant amount of money was lost. The search focused on incidents specifically impacting Celestia's core operations as opposed to any applications or services built on top of it.

Celestia employs a comprehensive set of unique security measures and features to enhance its blockchain architecture. Here are the key security features and unique aspects of the project:

1. Modular Architecture: Celestia is a modular blockchain that separates execution, consensus, and data availability. This allows for custom applications without affecting network congestion, improving performance and flexibility source.

2. Shared Security: Celestia utilizes a shared security model. New blockchains, such as rollups, can deploy on Celestia and instantly leverage its existing security infrastructure, eliminating the need to establish a new validator set source.

3. Data Availability Sampling (DAS): This feature allows nodes to verify data availability efficiently without downloading entire blocks. Light nodes, such as those on smartphones, can participate in sampling, which increases security and throughput source.

4. Lazybridging: A feature that enables seamless asset transfers across multiple rollups and blockchains, facilitated by zero-knowledge (ZK) verification at the base layer, ensuring fast and secure transactions source.

5. Censorship Resistance: Data published on Celestia cannot be altered or removed by any single party. The network of decentralized validators ensures that posted data remains intact and available for validation by rollups source.

6. Sovereignty and Custom Governance: Rollups on Celestia can operate autonomously, enabling communities to set and manage their rules without relying on a monolithic governance model common in traditional blockchains source.

7. Ginger Upgrade: This recent consensus upgrade doubles data availability throughput by reducing block times and supports potential block size increases, improving throughput and transaction finality source.

As for vulnerabilities, while Celestia has undergone various audits to minimize risks, the project still faces challenges such as market volatility impacting its native token TIA and the technical complexities inherent to modular blockchain architecture source.

Based on the available information, here are the security audits conducted for the Celestia project, listed in chronological order from the most recent:

• Zellic Audit: Conducted by Zellic, a top-tier security auditor, as part of a comprehensive security audit for the Omni protocol. Published on November 14, 2024.

No additional audits or details were found in the data retrieved. This list may not be exhaustive, and further verification through original sources or more specific searches could provide more audit details.
