A direct airdrop distributes tokens directly to user wallets based on a snapshot of past activity, often unexpectedly. An airdrop points system is a transparent, ongoing campaign where users accumulate points for specific actions (e.g., trading, providing liquidity). These points are later converted into a token allocation at a predetermined rate. Points systems create anticipation and allow users to actively work towards a larger reward, whereas direct airdrops are typically retroactive rewards.

Under worst-case, "fat-tailed" slashing distributions, the required reward multiplier increases dramatically. Standard models using Poisson or binomial distributions underestimate the risk of extreme, correlated slashing events. To compensate for this tail risk, the multiplier must be calibrated based on metrics like Conditional Value at Risk (CVaR), which measures the average loss in the worst 1% of scenarios, rather than the expected loss. If the expected annual loss is 0.1% but the CVaR is 5%, the reward must be sufficient to cover this potential 5% loss in a crisis year. This could mean multipliers an order of magnitude larger than those derived from standard models, ensuring the system remains secure and operators are adequately compensated even under catastrophic conditions.

How does required reward multiplier vary under worst-case slashing distributions? Under worst-case slashing distributions, which have "fat tails" (a higher likelihood of extreme events than a standard model like Poisson would predict), the required reward multiplier escalates dramatically. A standard model might estimate a 0.1% slashing probability, but a fat-tailed distribution acknowledges a non-negligible chance of, say, a 1% correlated slashing event. This drastically increases the expected loss and, more importantly, the perceived risk for operators. To compensate for this tail risk, the reward multiplier must be substantially higher. Operators will demand a large premium for the possibility of a systemic failure that could wipe out a significant portion of the staking pool. Ignoring worst-case distributions leads to a dangerously underfunded security model that is vulnerable to black swan events.
