Stellar is an open-source, decentralized blockchain network designed for facilitating payments and remittances quickly and at a low cost. It aims to connect financial institutions, payment systems, and people, acting as a bridge to convert cryptocurrency to fiat money (government-issued currency) simply. Unlike many blockchain platforms that use energy-intensive consensus mechanisms like Proof-of-Work (PoW), Stellar employs the Stellar Consensus Protocol (SCP), which relies on a model called Federated Byzantine Agreement. This allows transactions to be confirmed faster and more efficiently. The network is maintained by a non-profit organization, the Stellar Development Foundation, which supports the growth and development of the Stellar ecosystem. Its native cryptocurrency, Lumens (XLM), is used for transaction fees and to facilitate multi-currency transactions. Stellar’s unique attribute is its ability to handle asset tokenization and support cross-border payments, making it a powerful tool in the global finance system.

Stellar was founded in July 2014 by Jed McCaleb, David Mazières, and Joyce Kim. These founders aimed to create a "decentralized protocol for sending and receiving money in any pair of currencies." Prior to founding Stellar, Jed McCaleb co-founded Ripple, indicating his significant experience in developing financial protocols. The Stellar Development Foundation (SDF), a non-profit established to steer the development of Stellar, was also founded in 2014, and it continues to maintain the network today.

No, you cannot stake any tokens in the Stellar project. Stellar uses the Stellar Consensus Protocol, which does not involve traditional staking mechanisms like those found in Proof-of-Stake systems.

Based on the available information, there is no record of the Stellar protocol itself experiencing significant hacks or exploits that resulted in substantial monetary loss to the network or native protocol up to the current date, April 4, 2025. The search did not reveal any such events that match the specified criteria.

The Stellar network employs several security measures and protocols to safeguard its operations, with certain aspects unique to its design:

• Stellar Consensus Protocol (SCP): Stellar uses SCP, a unique consensus mechanism characterized by its energy efficiency and low-cost operations. It achieves consensus through a decentralized voting process, ensuring quick transaction confirmations without the need for intensive computation, distinguishing it from Proof-of-Work systems like Bitcoin's.

• OpenZeppelin Partnership: Starting 2025, Stellar partnered with OpenZeppelin to enhance the security of its smart contract platform, Soroban. This partnership includes thorough security audits (40 Auditor Weeks) and a bug bounty program to proactively address potential vulnerabilities (source).

• Protocol Upgrades (Protocol 22): Stellar has continuously evolved through upgrades like Protocol 22, which focus on enhancing privacy and scalability while maintaining low operational costs (source).

• Bug Bounty Programs: The Stellar Development Foundation (SDF) runs a robust bug bounty program incentivizing the discovery of vulnerabilities within its protocol, offering rewards of up to $250,000 in XLM or up to $50,000 in USD for issues discovered on Soroban (source).

• Open-Source Development: The Stellar protocol is open-source, with over 135 repositories on GitHub, allowing for community contributions and transparency in addressing potential security flaws (source).

Challenges and Vulnerabilities:

• Centralized Control Concerns: One concern is the potential over-centralization due to the SDF's significant control over the supply of Lumens (XLM). This control could impact trust in the network's decentralization but is something Stellar actively manages through community engagement and regulation (source).

Overall, Stellar's unique consensus protocol and commitment to security set it apart, although it must continually address and mitigate centralization concerns to maintain trust and security across its network.

Here are the known audits conducted for the Stellar project, listed with the auditing entity and date when available:

• 2025: Partnership with OpenZeppelin for enhancing Stellar smart contract development with a focus on security through a dedicated 40 Auditor Weeks of security audits. The partnership runs from January 2025 to December 2026 source.
• November 2024: Coinspect completed audits on Stellar's Soroban contracts for General Message Passing and Balanced, as Stellar expanded to its tenth blockchain source.
• May 2024: Audit by OtterSec on Soroswap.Finance, facilitated by the Stellar Development Foundation's "Audit Bank" initiative. This audit identified and resolved multiple vulnerabilities source.

These audits highlight a strong focus on the security and integrity of Stellar's systems and smart contracts.
