NEAR Protocol is a decentralized platform designed to support and scale applications much like the current internet but with enhanced capabilities thanks to its blockchain backbone. It uses a consensus mechanism known as Thresholded Proof of Stake (TPoS), where nodes stake NEAR tokens to participate in transaction validation and governance, incentivizing network participation. NEAR Protocol enhances scalability through Nightshade Sharding, a technique which splits the blockchain into smaller parts called shards to process many transactions simultaneously, increasing efficiency. This protocol is particularly tailored for decentralized applications (dApps) and supports various modern use cases like Decentralized Finance (DeFi), which involves blockchain-based financial services, and Non-Fungible Tokens (NFTs), which are unique digital assets. A key feature is its compatibility with Ethereum through tools like the Aurora Bridge, allowing developers to migrate or build Ethereum-compatible dApps within NEAR's robust ecosystem at lower costs and with higher throughput.

NEAR Protocol was founded in 2017 initially as "NEAR.ai" by Illia Polosukhin and Alexander Skidanov. The founders have strong backgrounds in technology and programming. Illia Polosukhin previously worked with Google on Google's innovative machine learning projects. Alexander Skidanov was the Director of Engineering at MemSQL (now called SingleStore), where he focused on SQL database advancements. After starting with a focus on program synthesis (computer-automated software development), they shifted towards developing a more scalable blockchain solution, namely the NEAR network, when Ethereum's technology did not meet their needs. The development of the NEAR network began in August 2018, and the mainnet officially launched in April 2020, with full network participation and governance handed over to the community in October 2020.

Yes, you can natively stake tokens in the NEAR Protocol project. Here is a breakdown of how staking works:

Token to Stake

• NEAR is the native cryptocurrency of the NEAR Protocol. It is used for staking to participate in network security and to earn rewards.

Staking Process

• NEAR Protocol uses a Proof-of-Stake (PoS) mechanism where token holders can either run validators themselves or delegate their tokens to validators who operate network nodes. This delegation allows holders to earn rewards without running a node.
• Token holders can use platforms like the official NEAR wallet, Moonlet, or Dokia Capital to stake their NEAR tokens. There are both lockup and non-lockup options for staking.

Rewards for Stakers

• Stakers earn a portion of the network's inflationary rewards. The static inflation rate is approximately 4.5% annually, meaning stakers can earn new tokens generated from this rate.
• The actual reward distributed to a staker depends on their proportion of total staked tokens in the network, and validators may share rewards with delegators.
• Additional rewards can be earned through stake farming initiatives where validators may partner with other projects to distribute project tokens along with NEAR rewards.

Considerations

• There is a minimum threshold of NEAR required to stake by validators, known as the "seat price," which adjusts dynamically based on network conditions.
• Stakeholders are encouraged to distribute their NEAR tokens across multiple validators to support decentralization efforts and mitigate risks.

Staking NEAR not only benefits individual token holders through rewards but also contributes to the security and decentralization of the network.

The NEAR Protocol has not experienced any hacks or exploits resulting in a significant loss of funds or causing outages within the specified timeline. However, in October 2024, a potential vulnerability dubbed the "Web3 Ping of Death" was discovered, which could have crashed every node on its network. Importantly, this flaw was patched before any exploitation occurred, so no funds were lost, and no outages resulted from this issue. The proactive measures taken and the collaboration with the security firm Zellic highlight the protocol's diligence in maintaining network security.

NEAR Protocol implements several security measures to ensure the safety and integrity of its network, leveraging unique features to enhance its robustness:

1. Consensus Mechanism:

   • Utilizes a Proof-of-Stake (PoS) mechanism, encouraging validators to lock up cryptocurrency collateral, thus promoting honest network participation and making it costly for malicious activities source.

2. Sharding:

   • The Nightshade technology enables advanced sharding, dividing the network into "shards" to enhance scalability and reduce single points of failure. Each shard processes a fraction of transactions independently, which increases security by making it harder to coordinate attacks across shards source.

3. Advanced Cryptography:

   • NEAR employs secure cryptographic algorithms and encryption methods to protect data integrity and confidentiality. This cryptographic foundation is critical for safeguarding sensitive on-chain data source.

4. Two-Factor Authentication (2FA):

   • Strengthens wallet security by requiring additional verification, which minimizes unauthorized access and helps protect user assets source.

5. Continuous Auditing and Bug Bounties:

   • Regular security audits and bug bounty programs are implemented to identify and rectify vulnerabilities proactively. This involves collaborating with the security community to keep defenses current against emerging threats source.

6. Community Governance:

   • NEAR's governance model allows token holders to propose and vote on security upgrades, fostering a decentralized approach to security maintenance and ensuring that challenges are addressed collaboratively source.

7. Integration with Other Protocols:

   • Uses interoperability solutions like the Rainbow Bridge to facilitate seamless asset transfers between Ethereum and NEAR, helping broaden security scope in a multi-chain environment source.

Recent developments and security advancements in NEAR include significant upgrades to its consensus and sharding architecture. The shift towards stateless validation aims to further streamline transaction processes and minimize storage needs, potentially increasing overall network security source. However, like any complex blockchain, NEAR remains vigilant against possible vulnerabilities and continually adapts its security strategies to mitigate risks effectively.

Here are the known audits of the NEAR Protocol, listed in chronological order from the most recent:

• Audit by Gauntlet (Discussed since July 2024): Proposed as part of the House of Stake governance framework to enhance security and governance of NEAR Protocol. Details

• Audit by South Pole (Year 2021): Focused on the NEAR Protocol's carbon footprint, achieving Carbon Neutral Product Label by assessing the emissions related to NEAR Foundation, Core Collective, and validators. Source

• Smart Contract Audit Program (Launched June 2022): This program was initiated by the NEAR Foundation to facilitate regular audits for the smart contracts deployed on the platform. NEAR Blog

There is limited publicly available information on specific audit reports by individual auditors for NEAR Protocol. The Smart Contract Audit Program and the environmental audit by South Pole are the most detailed entries.
