About ForTube

ForTube is the world’s top DeFi lending platform based on The Force Protocol, committed to providing decentralized lending services for cryptoasset enthusiasts worldwide. Based on smart contracts and automated algorithm technology, users can earn interest on deposited currency and pay interest on their borrowed currency.

About ForTube 2.0 Yield Farming

ARPA is now added on ForTube liquidity mining, reward index 0.15, APY 1.96%.

Total rewards: 85,000,000 FOR

Release speed: initial daily release amount is 500,000 FOR. Daily release amount will be timely adjusted according to [the user growth of the ForTube platform], [the growth of assets on the platform], and [the price of FOR in the secondary market].

Mining period: long-term incentives

Mining rules: weighted net assets mining

The APYs are directly related to the amount and type of deposited assets and borrowed assets. Different tokens have different incentives indexes (weights). Depositing assets with higher weights can get higher APY.

The incentive indexes of the assets that have been supported by the ForTube platform are as follows:

Please notice:

The indexes of all the remaining assets that are not listed in the above chart are temporarily 0.

Users can initiate proposals for adding new assets and vote on the incentive indexes of different assets every week on the ForTube governance platform

The calculation formula for the【Weighted Net Asset A】:

Vi is the deposit value of the asset i, Vj is the borrowing value of the asset j, and Fi and Fj are the mining reward indexes of assets i and j.

The calculation formula of the user’s daily mining reward is:

∑Ak is the sum of the weighted net assets of all users.


  • If a user deposited $10,000 worth of ETH (reward index is 2) and withdrew $3000 equivalent worth of USDT (reward index is 1), then the weighted net asset value of the user is 10000*2–3000*1= $17000. The user can earn【mining rewards】+【deposit interests】 dynamically according to the proportion of 【$17,000】in the【weighted net assets】of the entire platform.
  • If a user deposited $10,000 equivalent worth of BNB (reward index is temporarily 0), then the weighted net asset value of the user is 10,000*0= $0. The user can earn deposit interest but no mining reward.
  • If a user deposited $10,000 equivalent worth of HT (reward index is 0) and withdrew $3000 equivalent worth of USDT (reward index is 1), then the weighted net asset value of the user is 10000*0–3000*1= -$3000. The user can earn deposit interest but no mining reward, and need to pay the borrowing interest.
  • Account asset snapshot: The system will take a random snapshot of all users’ assets three times a day, and then take the average of the three times into the mining reward calculation.
  • Reward distribution and withdrawal: The system will distribute the rewards for the preceding day from 0 AM to 3 AM every day, and users can withdraw at any time once received the rewards.

About ARPA

ARPA is a blockchain-based solution for privacy-preserving computation, enabled by Multi-Party Computation (“MPC”). Founded in April 2018, the goal of ARPA is to separate data utility from ownership, and enable data renting. ARPA’s MPC protocol creates ways for multiple entities to collaboratively analyze data and extract data synergies, while keeping each party’s data input private and secure. ARPA allows secret sharing of private data, and the correctness of computation is verifiable using information-theoretic Message Authentication Code (MAC).

Developers can build privacy-preserving dApps on blockchains compatible with ARPA. Some immediate use cases include: credit anti-fraud, secure data wallet, precision marketing, joint AI model training, key management systems, etc. For example, banks using the ARPA network can share their credit blacklist with each other for risk management purposes without exposing their customer data or privacy.

Team members have worked at leading institutions such as Google, Amazon, Huawei, Fosun, Tsinghua University, Fidelity Investments. ARPA is currently assisting the China Academy of Information and Communications Technology in setting the national standard for secure multi-party computation. ARPA is a corporate member of MPC Alliance and IEEE and is in partnership with fortune 500 companies to implement proof-of-concepts and MPC products. In 2019, ARPA was named as the Top 10 most innovative blockchain companies in China by China Enterprise News and China Software Industry Association.
