Union: A ZK-powered interoperability protocol
Reasons to participate
Union is a cross-chain interoperability protocol based on zero-knowledge proof. It breaks the model of traditional cross-chain bridges relying on multi-signatures or centralized oracles. Its core architecture includes: CometBLS consensus mechanism (through BLS aggregate signature and MiMC zero-knowledge hash, it reduces verification costs and supports large-scale validators), Galoris zero-knowledge proof system (generates consensus proof in 7 seconds, with low threshold and can be run on personal devices), and Voyager repeater system (with automatic recovery, parallel processing, anti-pre-attack and other features), forming a trustless, efficient and stable cross-chain infrastructure.
In early December last year, Union announced the completion of a US$12 million Series A financing 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 and others, bringing its total financing amount to US$16 million.

Currently, the Union Foundation has been established, and the V2 version of the final stage test activity before the mainnet has also been launched, which is worth interacting with for free.
STEP 1. Get Holesky and Sepolia testnet tokens (collection link: https://cloud.google.com/application/web3/faucet ).
STEP 2. Exchange ETH on Holesky and Sepolia testnet into WETH (exchange link: https://sepolia.etherscan.io/token/0x7b79995e5f793a07bc00c21412e50ecae098e7f9#writeContract , https://holesky.etherscan.io/address/0x94373a4919B3240D86eA41593D5eBa789FEF3848#writeContract ).
STEP 3. Connect MetaMask and Keplr wallet to perform cross-chain operations directly on different 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, and is committed to jointly building an open network ecosystem. It supports a variety of network application scenarios, including data capture, VPN routing, content distribution, etc., and is highly scalable to meet various innovative network needs.
Yesterday, Ping Network officially announced that the app has been launched on iOS, Android and Chrome, and with the official launch, the first quarter of the points earning activity has also officially started. (Note: This project is an early project, please pay attention to the safety of funds when interacting)
Interactive Tutorial
The mining rules for Ping Network in the first season are: 1 point can be obtained for every 10 minutes of operation, and additional points can be obtained by inviting friends.
STEP 1. Go to the download link (link: https://download.pingnetwork.io/ ) to install it (the following demonstrates the Google Chrome interaction process).
STEP 2. Open the Google plug-in and click the task button to start mining (remember to log in to your account through Google Mail).
