Union: ZK-Driven Interoperability Protocol
Reasons to Participate
Union is a cross-chain interoperability protocol based on zero-knowledge proofs, breaking the traditional cross-chain bridge model that relies on multi-signatures or centralized oracles. Its core architecture includes: CometBLS consensus mechanism (reducing verification costs and supporting large-scale validators through BLS aggregated signatures and MiMC zero-knowledge hashes), Galoris zero-knowledge proof system (generating consensus proofs in 7 seconds, low threshold, can run on personal devices), and Voyager relay system (features automatic recovery, parallel processing, and protection against front-running attacks), forming a trustless, efficient, and stable cross-chain infrastructure.
In early December last year, Union announced the completion of a $12 million Series A funding round, led by Gumi Cryptos Capital and Longhash Ventures, with participation from Borderless Capital, Blockchange, ATOM Accelerator, Eterna Capital, Veris Ventures, LBank Labs, Gate Ventures, TRGC, etc., bringing its total funding to $16 million.

Additionally, Union has been listed on Kaito's Pre-TGE Community Leaderboard.
Interaction Tutorial
Currently, the Union Foundation has been established, and the final stage testing activity of the mainnet V2 version has also been launched, making it worth "zero-cost" interaction.
STEP 1. Obtain Holesky and Sepolia testnet tokens (Claim link: https://cloud.google.com/application/web3/faucet).
STEP 2. Exchange ETH on the Holesky and Sepolia testnets for WETH (Exchange links: https://sepolia.etherscan.io/token/0x7b79995e5f793a07bc00c21412e50ecae098e7f9#writeContract, https://holesky.etherscan.io/address/0x94373a4919B3240D86eA41593D5eBa789FEF3848#writeContract).
STEP 3. Connect MetaMask and Keplr wallets to perform cross-chain operations directly on supported networks (Link: https://app.union.build/transfer).
Ping Network: Decentralized Bandwidth Infrastructure
Reasons to Participate
Ping Network is a decentralized network infrastructure platform that connects users, node operators, and validators, dedicated to collaboratively building an open network ecosystem. It supports various network application scenarios, including data scraping, VPN routing, content distribution, etc., while possessing high scalability to meet various innovative network needs.
Yesterday, Ping Network officially announced that the application is now available on iOS, Android, and Chrome, and with this official launch, the first season of the points-earning activity has also officially begun. (Note: This project is an early-stage project, please pay attention to fund security during interaction.)
Interaction Tutorial
The mining rules for Ping Network's first season are: earn 1 point for every 10 minutes of operation, and additionally earn points by inviting friends.
STEP 1. Go to the download link (Link: https://download.pingnetwork.io/) to install (the following demonstrates the interaction process on Google Chrome).
STEP 2. Open the Google extension and click the task button to mine (also remember to log in with your Google account).
Miden: Ethereum Layer 2 Scaling Solution
Reasons to Participate
Miden is an Ethereum Layer 2 scaling solution based on zk-STARKs (zero-knowledge scalable transparent arguments) launched by Polygon, aimed at improving the scalability and security of the Ethereum network.
At the end of April, Miden announced the completion of a $25 million seed funding round led by a16z, Hack VC, and 1kx, with other investors including Finality Capital Partners, Symbolic Capital, and notable angel investors such as Aptos co-founder Avery Ching. Moreover, the team stated that 10% of the cryptocurrency issued by Miden in the future will be allocated to Polygon token holders.
