Airdrop

An Airdrop is a distribution of free tokens to a community, typically used as a marketing tool or a reward for early protocol adopters and testers. In 2026, the "points-to-airdrop" model has matured into merit-based incentive programs that utilize Sybil-resistance and Proof-of-Humanity to filter out bots. Airdrops remain a primary method for decentralized governance (DAO) bootstrapping. Follow this tag for the latest on retroactive rewards, eligibility criteria, and how to participate in the most anticipated token distributions in the ecosystem.

Coders Push ZK ‘Secret Santa’ System Toward Deployment

Coders Push ZK ‘Secret Santa’ System Toward Deployment

The post Coders Push ZK ‘Secret Santa’ System Toward Deployment appeared on BitcoinEthereumNews.com. Ethereum developers are refining a zero-knowledge protocol designed to bring stronger privacy guarantees to on-chain interactions, starting with a “Secret Santa”-style matching system that could evolve into a broader toolkit for private coordination. Solidity engineer Artem Chystiakov resurfaced the research on Monday in an Ethereum community forum post, pointing to work he first published in January on arXiv. The idea aims to recreate the anonymous gift-exchange game on Ethereum, where participants are randomly matched without anyone learning who is sending to whom. Doing that on a transparent blockchain, however, requires solving several long-standing issues around randomness, privacy and Sybil-resistance. Chystiakov said the core problems are straightforward: “Everything on Ethereum is visible to everyone,” blockchains do not provide true randomness, and the system must prevent users from registering multiple times or assigning gifts to themselves. The proposed protocol uses zero-knowledge proofs to verify sender–receiver relationships without revealing identities, and a transaction relayer to submit moves so individual wallets cannot be linked to actions. In the proof-of-concept, participants register their Ethereum addresses in a smart contract and commit to a unique digital signature, which blocks duplicate entries. Each participant then submits a random number to a shared list through the relayer. Because the relayer broadcasts the transactions, no one can tell which address contributed which number. Receivers encrypt their delivery details using these shared numbers, ensuring only their assigned counterpart can decrypt them. A participant then selects someone else’s random number, completing the matching. At that point, the protocol reveals the receiver’s identity only to the person assigned as their “Santa,” keeping the rest of the network blind to the pairing. The work slots into a broader push to design privacy frameworks for Ethereum as crypto systems increasingly intersect with regulated finance. Zero-knowledge layers of this type can be adapted to anonymous…

Ethereum developers push forward with the deployment of the ZK-based "Secret Santa" system.

PANews reported on December 2nd, citing CoinDesk, that Ethereum developers are refining a zero-knowledge protocol designed to provide stronger privacy guarantees for on-chain interactions. The project starts with a matching system similar to a "secret Santa," which is expected to evolve into a wider suite of private collaboration tools. Solidity engineer Artem Chystiakov revisited this research in a post on the Ethereum community forum on Monday, mentioning his initial work published on arXiv in January. The idea is to recreate an anonymous gift-swapping game on Ethereum, where participants are randomly paired and no one knows who is sending gifts to whom. However, achieving this on a transparent blockchain requires addressing several long-standing issues surrounding randomness, privacy, and resistance to Sybil attacks. Chystiakov states that the core problem is simple: "Everything on Ethereum is visible to everyone," the blockchain cannot provide true randomness, and the system must prevent users from registering multiple times or assigning gifts to themselves. The proposed protocol uses zero-knowledge proofs to verify the relationship between sender and receiver without revealing identity information, and uses transaction relayers to submit operations, so that no single wallet can be linked to a specific action. This type of zero-knowledge layer can be applied to anonymous voting, DAO governance, whistleblowing channels, and private airdrops or token distributions that avoid revealing receiver information.

Ethereum developers working on a ZK protocol for on-chain interactions privacy

Ethereum developers working on a ZK protocol for on-chain interactions privacy

Ethereum developers are advancing a new zero-knowledge protocol that aims to bring stronger privacy to on-chain interactions, beginning with a cryptographically verified Secret Santa–style matching system.Though playful in theme, the work reflects a growing push within the Ethereum ecosystem to design practical privacy frameworks that can be deployed across a range of real-world applications.A push for private coordination in EthereumThe idea resurfaced recently after Solidity engineer Artem Chystiakov highlighted research he and collaborators first published earlier this year.Their proposal, known as the ZK Secret Santa (ZKSS) protocol, describes a method for matching participants on-chain without exposing who is assigned to whom.The challenge is heightened by Ethereum’s fully transparent state, lack of native randomness and the long-standing problem of Sybil resistance.To address these constraints, the ZKSS design leans heavily on zero-knowledge proofs, transaction relayers and cryptographic nullifiers.Together, these tools allow participants to prove their place in the game, contribute randomness and receive assignments without revealing the underlying identity linkages that would otherwise be visible on-chain.The use of a relayer is central to the privacy guarantee. During the matching phase, participants submit their randomness through the relayer, which broadcasts the transactions on their behalf.Because the relayer masks the origin of each submission, no observer can infer which address contributed which value.The protocol’s zero-knowledge proofs then verify that each randomness submission is valid, tied to a legitimate participant and not duplicated.Inside the three-step protocolThe ZKSS system unfolds in three coordinated steps.First, all participants are registered in a smart contract, which stores their addresses in a sparse Merkle tree.This setup needs to be done only once, allowing for repeated Secret Santa rounds without rebuilding the participant list.The registration tree later enables proof-based membership checks without exposing wallet relationships.The second stage, called signature commitment, requires each participant to commit to a deterministic ECDSA signature.This commitment prevents them from using signature variability to bypass anti-Sybil protections.Each signature hash is stored in a separate Merkle tree, with the contract verifying that the sender belongs to the initial participant set.After committing, players generate and publish a unique randomness value. They do this privately, but their proof shows that the randomness belongs to a legitimate participant and hasn’t been reused.Players are encouraged to use RSA public keys as their randomness so they can later receive encrypted delivery details from their assigned counterpart.The final step is the receiver disclosure phase. Here, each participant reveals themselves to the person who drew their randomness. They provide a proof showing they are not claiming their own slot and that their nullifier does not conflict with the randomness they selected.With this final verification step, the protocol completes the matching without leaking any sender-receiver mappings to the public chain.A framework with broader usesAlthough framed as a Secret Santa algorithm, the implications reach far beyond seasonal gift exchanges.Ethereum’s growing intersection with regulated finance, governance, and organisational coordination has amplified the need for permissionless privacy systems.The same framework can support anonymous voting in DAOs, whistleblower channels where members must prove eligibility without exposing identity, and private airdrops that avoid revealing recipient lists.Its structure, Merkle trees for membership checking, deterministic signatures for Sybil resistance, and zero-knowledge proofs for correctness, mirrors the backbone of many emerging privacy-first protocols.Developers expect continued refinement as the community tests the ZKSS design and explores interoperability with existing Ethereum tooling.The early research suggests that privacy-preserving, verifiable coordination can be achieved without trusted intermediaries, marking a notable step toward more confidential activity on public blockchains.The post Ethereum developers working on a ZK protocol for on-chain interactions privacy appeared first on Invezz
