MetaLeague Integrates Chainlink VRF to Help Fairly Allocate Football Clubs to In-Game League
MetaLeague the NFT Football Manager game — has integrated Chainlink Verifiable Random Function (VRF) on Polygon mainnet.
By integrating the industry-leading decentralized oracle network, we now have access to a tamper-proof and auditable source of randomness needed to randomly generate the level of the League for each Football Club in the game, where the players can compete with other Managers.
MetaLeague is a football-inspired universe where you can own a football Club with unique players, manage the strategy and tactics, and build the best team in the blockchain-based game. You can be the Club manager and the owner of a unique MetaLeague NFT Club with unique NFT players.
Users can take part in the League and compete to reach the highest rankings of the game. In the first League organization, MetaLeague currently has 4 different levels (or divisions), similar to the English football league pyramid system. In each division there is a specific number of championships, with 20 clubs for each one:
- 20 Clubs in Division 1 unique championship
- 40 in Division 2 (with 2 championships)
- 80 in Division 3 (with 4 championships)
- 160 for Division 4 (with 8 championships)
Moreover, every MetaLeague player is a randomly generated NFT, with billions of different combinations. They have various skills and characteristics like role, nationality, age, height, and more.
In order to assign a Club to a specific Division of the League pyramid system, we need access to a secure random number generator (RNG) that any user could independently audit. However, RNG solutions for smart contracts require several security considerations to prevent manipulation and ensure system integrity. For instance, RNG solutions derived from blockchain data like block hashes can be exploited by miners/validators, while off-chain RNG solutions derived from off-chain APIs are opaque and don’t provide users with definitive proof about the integrity of the process.
MetaLeague aim to leverage Chainlink decentralized services in their next development steps with the integration of Chainlink Data Feeds and Keepers into the smart contract of the game, in order to automate specific gaming features and updates. Together with these integration plans, the goal of MetaLeague is to be multichain, providing the Managers playing on “Local” Leagues on different chains, with the opportunity to compete and challenge each other in “Global” Leagues cross-chain. We’re currently planning launches on Avalanche and BNB Chain.”
“As a first step, we decided to integrate Chainlink VRF in MetaLeague in a fundamental part of the game — the initial on-chain verifiably random assignment of the Club League’s Division. This integration also helps ensure that Club Managers can transparently and fairly generate tamper-proof NFTs. This transparent set of rules for our managerial games is in line with our open-source philosophy, much like our decision to publish the off-chain gameplay algorithms.” — Maurizio Palumbo, Founder of MetaLeague

About MetaLeague
MetaLeague is a startup project, created by a small indie team with an experience of more than 15 years in the design and development of managerial sports games. The goal of the MetaLeague team is to create a series of managerial and strategic games of different sports, with Play to earn features and NFT based.
The first game is a multiplayer football universe where the user/manager can own their NFTs of football players and clubs to compete with other real players in multichain global Leagues.
