Airdroplyx Web3 Glossary
The comprehensive dictionary of blockchain, DeFi tokenomics, zero-knowledge cryptography, and retroactive airdrop terminology explained in plain English.
Sybil Attack
Creating dozens or hundreds of pseudo-anonymous wallets by a single entity to unfairly drain airdrop allocations.
In Web3 airdrops, protocols deploy machine learning and on-chain graph analysis to detect clusters sharing common funding sources, synchronized timestamps, or identical transaction values. Wallets caught in a Sybil cluster are blacklisted and receive zero tokens.
Retroactive Airdrop
Distributing governance tokens retroactively to early users based on their historical mainnet or testnet activity before an unannounced snapshot date.
Pioneered by Uniswap in 2020 ($UNI), retroactive airdrops reward authentic adopters who tested the protocol when no economic guarantee existed, transforming community members into decentralized stakeholders.
TGE (Token Generation Event)
The precise cryptographic moment when a protocol smart contract officially mints and initiates public circulation of its native token.
TGE is typically accompanied by airdrop claim portals opening, decentralized exchange liquidity pool initialization, and Tier-1 centralized exchange trading listings.
Snapshot
A frozen ledger record of all blockchain transactions and wallet balances captured at a specific block height to determine airdrop eligibility.
Any transaction executed after the snapshot block height does not count towards the airdrop. High-profile protocols frequently conduct snapshots months before public announcements to thwart mercenary farmers.
Fully Diluted Valuation (FDV)
The total theoretical market capitalization of a cryptocurrency project if 100% of its maximum token supply were in active circulation at the current price.
Calculated as Current Token Price × Total Maximum Supply. Low circulating supply paired with exorbitant FDV often leads to aggressive post-airdrop price depreciation during venture cliff unlocks.
Vesting & Cliff
A temporal lockup schedule where token allocations are released incrementally over months or years, often preceded by a cliff period.
A "cliff" represents a duration (e.g. 12 months) during which zero tokens unlock. After the cliff date passes, tokens vest linearly each block or month to prevent founders and venture capitalists from dumping allocations.
Proof of Humanity (PoH)
Cryptographic attestation frameworks (like Gitcoin Passport, World ID, Linea PoH) verifying that a wallet belongs to a distinct living human.
By tying biometric iris scans, social credentials, or decentralized identity stamps to an Ethereum address, protocols can grant airdrop multipliers while disqualifying automated script syndicates.
zk-SNARK / Zero-Knowledge Proof
A cryptographic primitive allowing a prover to demonstrate that a statement is mathematically true without revealing the private inputs.
In Layer 2 rollups (Starknet, zkSync, Scroll, Linea), validity proofs compress thousands of transactions into a succinct cryptographic proof verified cheaply on Ethereum L1.
Restaking & AVS
Rehypothecating staked ETH or LSTs (via EigenLayer, Symbiotic, Karak) to secure third-party Actively Validated Services in exchange for additional yield.
Restaking creates dual-yield structures where depositors earn Ethereum base staking rewards alongside secondary protocol tokens, introducing novel economic slash risk.
Paymaster (ERC-4337)
A specialized smart contract in Account Abstraction that sponsors transaction gas fees for users or enables fee payment in ERC-20 stablecoins.
Paymasters eliminate the frustrating Web3 onboarding friction of needing native ETH in a new wallet before being able to interact with dApps or claim airdrops.
DePIN (Decentralized Physical Infrastructure)
Decentralized networks leveraging token incentives to crowdsource real-world hardware, such as wireless bandwidth, compute GPUs, and mapping sensors.
Protocols like Grass, Helium, DIMO, and Hivemapper reward ordinary users for contributing excess WiFi or telemetry, making DePIN one of the most accessible zero-capital airdrop categories.
Extended UTXO (EUTXO)
Cardano and Ergo accounting model extending Bitcoin UTXOs with arbitrary state datums, redeemers, and deterministic execution scripts.
Unlike Ethereum account-based global state machines, EUTXO transactions evaluate deterministically off-chain with 100% predictable gas costs and immunity to MEV front-running.
MEV (Maximal Extractable Value)
Profit extracted by block producers or searcher bots through reordering, inserting, or censoring pending transactions in the public mempool.
Sandwich attacks force airdrop traders to incur high slippage. Intent-based decentralized exchanges (like CowSwap) shield users from MEV by executing batch auctions.
Data Availability (DA)
The mathematical guarantee that all transaction data required to reconstruct blockchain state has been published and made accessible to all nodes.
Modular DA layers like Celestia, EigenDA, and Avail dramatically reduce Layer 2 rollup transaction costs by decoupling storage verification from consensus execution.
Faucet
A community or foundation web portal that dispenses free testnet cryptocurrency (Sepolia ETH, MON, BERA) for testing decentralized applications.
Faucets enforce rate-limits (e.g. 1 drip every 24 hours) and captchas to prevent automated bots from draining test liquidity reserves.
