CASE STUDY

BOTANIX 2100 AIRDROP CAMPAIGN BACKEND

BeAWhale engineered the backend system powering Bitcoin 2100 – Botanix Labs’ gamified airdrop campaign where users earn real satoshis through daily check-ins, provably fair mini-games, block predictions, and NFT-gated VIP access, all tied to Bitcoin airdrop eligibility. The backend shipped in 2 months with a team of 3 specialists.

THE CHALLENGE

PROVABLY FAIR
BITCOIN CAMPAIGNS

Airdrop campaigns in crypto are everywhere – but most are shallow point-farming exercises with no real engagement, no on-chain mechanics, and no lasting value. They attract bots, burn budgets, and leave projects with inflated user counts but no genuine community.

Botanix Labs needed something different. They were launching their Bitcoin Layer 2 mainnet and wanted a campaign that would onboard real users into the ecosystem – not through passive tasks, but through interactive games that required actual on-chain transactions on the Botanix network. The vision: a virtual Bitcoin City with a VIP Citadel, four distinct mini-games, NFT-based access control, and a rewards system that pays out real satoshis convertible to BTC.

The backend challenge was immense. Every game needed its own concurrency model, fairness guarantees, and payout logic. The system had to handle thousands of concurrent players, prevent bot abuse, integrate with third-party task platforms, manage NFT minting and verification, and run a scalable Bitcoin payout pipeline – all within a 2-month window to align with the mainnet launch.

FEATURES

What we built FOR MVP

PAYOUT ENGINE

Converts in-game satoshis to real BTC payouts. Handles batch processing, wallet disbursement, and sats-to-BTC conversion at scale. Aggregated scoreboards across all games determine airdrop eligibility.

VIP & REFERRAL SYSTEM

NFT-gated access to the Bitcoin Citadel and its exclusive games. Wallet authentication ties NFT ownership to eligibility. Referral codes reward both sides with sats. Anti-bot layers – captcha, behavioral detection, rate limiting – keep the system clean.

PROVABLY FAIR LOGIC

Cryptographic fairness tied to on-chain data. Spin outcomes use verifiable randomness. Block predictions derive from real Bitcoin hashes, verified after 6 confirmations. Every result is auditable. No one can manipulate outcomes.

ROLE-BASED ACCESS

Satoshi Spin – 1 sat per spin, guaranteed prizes from 2 to 10 million sats. Mining Sats – daily check-ins with streak multipliers. Predict the Block – 100-sat lottery on the last 6 hex characters of a Bitcoin block hash. Satoshi’s Keys – weekly treasure hunt where daily clues lead to a SHA-256 private key unlocking 0.1 BTC.

KEY FEATURE

HOW DOOES PROVABLY FAIR
SYSTEM work?

Every game in Bitcoin 2100 that involves randomness or prediction uses verifiable on-chain data to guarantee fairness. No one – not even the game operators – can manipulate outcomes.

01 Player Action

User places a bet, spins the wheel, or submits a block hash prediction with an on-chain transaction

02 On-Chain Randomness

Outcomes are determined using cryptographic randomness derived from Bitcoin block data – tamper-proof by design

03 Verification Window

For block predictions, results wait for 6 confirmations to account for chain reorganizations before finalizing

04 Instant Payout

Verified winners receive sats credited to their account, redeemable as real BTC through the automated payout pipeline

DETAILED

What you might want to KNOW

Can you build gamified blockchain campaigns at scale?

Yes – Bitcoin 2100 is a full-scale gamified airdrop backend with four distinct mini-games, NFT access control, a referral system, leaderboards, and a real Bitcoin payout pipeline. We handled all game logic, concurrency, fairness algorithms, anti-bot measures, and third-party integrations. The system was built to handle thousands of concurrent users interacting with on-chain mechanics simultaneously.

How do you ensure fairness in blockchain-based games?

Every game with a random or predictive element uses provably fair algorithms tied to on-chain data. For Predict the Block, outcomes are derived from actual Bitcoin block hashes verified after 6 confirmations. For Satoshi Spin, cryptographic randomness determines prizes. All outcomes are verifiable on-chain – the system is designed so that neither operators nor players can manipulate results.

How did you handle anti-bot protection for a campaign distributing real Bitcoin?

With real sats on the line, bot prevention was critical. We implemented multi-layered defenses: captcha challenges, behavioral analysis, wallet-based authentication tied to NFT ownership, and rate limiting across all game endpoints. The combination of on-chain transaction requirements and off-chain verification makes automated abuse significantly harder than typical Web2 airdrop campaigns.

Can you integrate with third-party Web3 platforms?

Yes. Bitcoin 2100’s backend integrates with Galxe and Intract for external task validation, verifying that users completed off-platform quests before crediting rewards. We also built NFT minting flows, wallet authentication, and bridge interactions with the broader Botanix ecosystem. Third-party integrations are handled through robust API layers with retry logic and validation.

How fast can you build a campaign backend like this?

We delivered the full Bitcoin 2100 backend in 2 months with 3 developers – 2 backend engineers and 1 Web3 specialist. That included all four game engines, the NFT pipeline, referral system, leaderboards, anti-bot infrastructure, payout automation, and third-party integrations. Tight timelines are manageable when the architecture is right and the team has deep blockchain experience.

What blockchain infrastructure does BeAWhale work with?

We build across multiple chains and protocols. For Bitcoin 2100, the backend operates on the Botanix Bitcoin L2 network with direct Bitcoin payout mechanics, NFT minting, and on-chain game transactions. We’ve also delivered projects on Solana (token launch bots), Ethereum-compatible chains (DeFi lending), and cross-chain payment platforms. We choose infrastructure based on what the product requires.
