Introducing BITE Protocol: The End of MEV and the Dawn of Blockchain Privacy

By providing decentralized trust, blockchain technology has revolutionized digital interactions, from finance to gaming. Yet, as adoption grows, serious challenges have emerged, undermining user confidence. 

Issues like front-running, privacy invasions, and unfair transaction handling, collectively known as Maximal Extractable Value (MEV), threaten the integrity and usability of blockchain platforms. Enter BITE (Blockchain Integrated Threshold Encryption) Protocol, a first-of-its-kind technology designed to eliminate these issues at the Consensus level and usher in a new era of fairness and privacy in blockchain ecosystems.

The Problem – Why Traditional Blockchains Aren’t Fair

Today’s blockchain users frequently experience MEV attacks, situations where miners or validators and block builders exploit their visibility in the mempool to manipulate blocks and steal funds from users. Common examples include front-running trades on decentralized exchanges or executing sandwich attacks, resulting in significant financial losses and compromised user privacy. In fact, users have lost nearly $2B to MEV since 2020. 

Beyond financial losses, traditional blockchain transactions lack fundamental privacy, exposing sensitive financial or personal information, and further reducing overall trust.

The Solution – Introducing BITE Protocol

BITE Protocol addresses these critical issues by introducing threshold encryption at the blockchain’s consensus layer. Imagine sending your blockchain transactions like mailing sealed envelopes; no one, not even validators or block builders, can view the contents until they're safely delivered and opened at the intended destination. 

BITE achieves this by encrypting transaction details before they are sent to the chain. This encryption ensures complete confidentiality of transaction information during the entire validation and consensus process, eliminating any possibility for front-running or other malicious MEV strategies. By doing so, BITE Protocol fundamentally enhances fairness, trust, and privacy across blockchain transactions.

The immediate benefits of BITE Protocol include:

• Complete protection from front-running and MEV attacks.
• Reduced slippage and better exchange rates. 
• Enhanced transaction privacy.

Diving Deeper – How BITE Protocol Works

BITE Protocol fundamentally transforms blockchain transactions through threshold encryption, operating through the following sequence:

1. Prepare Encrypted Transaction

Before submission, transaction data (e.g., function calls) is encrypted client-side using BITE’s threshold encryption.

2. Network Broadcast & Signature Collection

Once submitted, the encrypted transaction is broadcast to the network. Validators validate and collect signatures, although transaction contents remain encrypted.

3. Pending State

While pending, transaction data remains encrypted onchain, fully obscuring the mempool from observers and validators.

4. Consensus and Decryption

Upon reaching consensus, a supermajority of validators can use their private shares to produce decryption shares. Combining these decryption shares reconstructs the original, unencrypted transaction data.

5. Post-Finality Behavior

Post-execution, the transaction data remains encrypted within block explorers and accessible only viaBITE-specificJSON-RPC calls.

This comprehensive approach removes informational asymmetry, rendering MEV attacks impossible, while maintaining essential onchain privacy and application integrity.

‍The BITE Protocol Four-Phase Roadmap & Real-World Use Cases

BITE Protocol employs a strategic, four-phase approach, each phase unlocking greater functionality and new real-world applications:

Phase 1: Threshold Decryption of Transactions by Consensus Node Committees

This foundational phase immediately mitigates MEV issues by encrypting transaction contents at submission.

• Decentralized Exchanges (DEXs): Completely remove front-running and sandwich attacks.
• On-chain Auctions: Enable fair, sealed-bid auctions where all bids are private until the cutoff time.
• Gaming: Prevent cheating in real-time move submissions or hidden strategies.
• Prediction Markets: Users submit encrypted predictions, keeping outcomes unbiased until event resolution.

Phase 2: Threshold Decryption of Encrypted Smart Contract Data by Consensus Node Committees

Expanding encryption capabilities, smart contracts will directly handle encrypted data, increasing privacy in blockchain interactions.

• Sealed-Bid Auctions: Bids are encrypted, stored on-chain, and revealed all at once to prevent sniping and timing advantages [see: Paradigm’s onchain auction research].
• Conditional Trading Triggers: Smart contracts execute actions only when encrypted thresholds or events are met.‍
• Time-Locked Messages or Wills: Data is decrypted and acted upon only at a future timestamp.

Phase 3: Threshold Re-Encryption of Encrypted Smart Contract Data by Consensus Node Committees

Introducing secure selective disclosure, BITE enables precise management of data visibility, greatly enhancing privacy.

• Private Social Networks: Encrypted posts are shared only with selected friends.
  On-Chain Subscriptions and Licensing: Access keys for digital content (videos, documents, NFTs) are selectively re-encrypted for paying users.
• Private DAOs: Confidential voting and proposal systems with member-specific visibility.
• Encrypted Order Books: Buyer data is encrypted and visible only to relevant sellers.

Phase 4: Threshold Fully Homomorphic Encryption (TFHE) inside Smart Contracts

The most advanced phase, TFHE, enables computation directly on encrypted data, transforming blockchain into a powerful, privacy-preserving computational network.

• Confidential DeFi: Fully private lending, borrowing, and AMMs.
• On-chain Banking: Maintain account balances, interest, and transfers entirely encrypted.
• Private Payroll: Employers can issue salaries and calculate bonuses without revealing on-chain amounts.
• Confidential Voting: Encrypted votes are counted via homomorphic addition, no need to reveal individual choices.
• Private Credit Scores: Prove solvency or creditworthiness without disclosing financial details.

Fair On-chain Auctions – A New Possibility with BITE

Historically, blockchain-based auctions suffered from inherent timing advantages, allowing participants to unfairly leverage visibility into others' bids. BITE Protocol's encrypted transactions introduce the ability to conduct truly fair auctions. Bids remain confidential, eliminating any unfair timing or visibility advantages and resulting in transparent, provably fair outcomes. This transformative capability opens blockchain technology to entirely new auction mechanisms, expanding potential applications significantly.

‍BITE Protocol vs. Other MEV Solutions

Unlike traditional MEV solutions that rely on off-chain methods, partial protections, or centralized services, BITE Protocol integrates encryption at the floor level of a decentralized network, the consensus layer, leaving no gaps for exploitations. 

The most popular form of MEV protection today is something known as a Private Mempool. With projects like Flashbots leading the way, private mempools are highly centralized and do not provide protection automatically i.e., you have to opt-in to a specific service.

BITE is the first integrated threshold encryption protocol designed to bring native MEV resistance to the consensus level of a Layer 1 blockchain. No roll-ups or protocols are stacked on top of a public blockchain with BITE.

This guarantees gapless MEV resistance for all transactions, significantly elevating fairness and security standards in any blockchain ecosystem integrating BITE. The phased roadmap further allows incremental adoption, progressively delivering advanced privacy and fairness capabilities.

What this Means for Blockchain

BITE Protocol is not just an incremental improvement—it's a foundational shift in how blockchain transactions are processed. By prioritizing provable fairness and transaction privacy at the consensus layer, BITE paves the way for blockchain technology to achieve broader adoption and deeper trust.
