Grudge Platform | May 2025
Gruda is a Layer 1 blockchain built on Polygon, designed to integrate gaming, GPU mining, and community engagement through its native ERC-20 token, GRUDA COIN (GRUDA). With a fixed supply of 10 million tokens, Gruda employs a hybrid consensus mechanism—Proof of Stake (PoS), Proof of Work (PoW), and Proof of Play™ (PoP)—to reward users for gameplay, social contributions, GPU and mobile mining, and ad sharing. As the economic backbone of the Nexus Nemesis trading card game (TCG), GRUDA enables seamless swaps for GBuX, the in-game currency for purchasing card packs and NFTs. This white paper outlines Gruda’s architecture, consensus node process, tokenomics, cross-chain bridge to Solana, renewable energy commitment, and SDK integration, offering a scalable, merit-based ecosystem for gamers, miners, and creators.
Gruda is a pioneering Layer 1 blockchain on Polygon, leveraging the Ethereum-compatible network’s scalability and low-cost transactions to power the Nexus Nemesis TCG, a flagship application of the Grudge Platform. The native GRUDA COIN (GRUDA), an ERC-20 token with 8 decimal places, supports a fixed supply of 10 million tokens, distributed over 36 months through merit-based minting and grants. Gruda’s Proof of Play™ mechanism rewards diverse contributions—gameplay in Nexus Nemesis, GPU mining with renewable energy, mobile mining, social engagement, and ad sharing—while a 0.5% transaction fee and a treasure hunt feature inspired by “The Pirate King” incentivize active participation. A Polygon-Solana bridge enables wrapped GRUDA (wGRUDA), enhancing interoperability. This paper provides a comprehensive overview, with a detailed focus on the consensus node process, and invites participation in the Season 0 presale.
The intersection of blockchain and gaming ecosystems faces several challenges:
Gruda addresses these issues by introducing a Layer 1 blockchain with a merit-based reward system, sustainable mining practices, and seamless integration with the Nexus Nemesis ecosystem, fostering a cohesive and rewarding environment.
Gruda is a Layer 1 blockchain built on the Polygon network, leveraging its Ethereum-compatible infrastructure for scalability and low transaction costs. The native GRUDA COIN (GRUDA) is an ERC-20 token with the following key features:
Nexus Nemesis, a trading card game (TCG) developed by the Grudge Platform, utilizes GRUDA as the cornerstone of its in-game economy. Players earn GRUDA tokens through gameplay achievements, such as winning matches or completing challenges, and can swap these tokens for GBuX, the in-game currency, at a fixed rate of 1 GRUDA = 100 GBuX. GBuX is used to purchase card packs (priced at 100 GBuX per pack), NFTs, and other in-game assets, creating a seamless economic loop from mining and gameplay to in-game purchases.
Gruda’s consensus mechanism is a hybrid model combining Proof of Stake (PoS), Proof of Work (PoW), and Proof of Play™ (PoP), with nodes responsible for transaction validation, block production, and merit action verification. This section provides a detailed mathematical framework for node operations, ensuring security, efficiency, and fairness.
Nodes are selected to propose and validate blocks based on their staked GRUDA tokens and reputation score. The selection probability for node \( i \) is:
P_i = (S_i × R_i) / Σ(S_j × R_j)
where \( S_i \) is the stake amount, \( R_i ∈ [0,1] \) is the reputation score, and the summation is over all \( N \) nodes. Reputation is updated dynamically:
R_i(t+1) = R_i(t) + 0.01 × (Success - 0.5 × Failure)
with \( R_i \) capped at 1. Success is a correct validation, and Failure is an incorrect or missed validation. The reward per block is:
R_i = 10 × 10^8 × P_i GRUDA
Nodes, particularly GPU partners, perform lightweight computational tasks to contribute to network security. The difficulty \( D \) adjusts dynamically:
D(t+1) = D(t) × (2 × H_current / H_target)
where \( H_current \) is the network’s hash rate, and \( H_target \) is the target (calibrated for 2-second block times). The reward is:
R_PoW = 0.05 × 10^8 × HashPower_i GRUDA
Nodes verify merit actions (gameplay, engagement, etc.) to mint rewards. The merit score for user \( u \) is:
M_u = 0.4 G_u + 0.2 E_u + 0.2 S_u + 0.1 M_GPU,u + 0.1 M_Mobile,u
where \( G_u \), \( E_u \), \( S_u \), \( M_GPU,u \), and \( M_Mobile,u \) are points for gameplay, engagement, social, GPU, and mobile mining. Reward:
R_u = min(M_u × Rate, 100 × 10^8) GRUDA
Nodes earn 0.02 GRUDA per verified action.
Nodes failing validation \( F \) times in 1000 blocks are slashed:
S_slash = S_i × (1 - e^(-0.1 F))
Uptime \( U_i < 0.95 \) reduces \( R_i \) by 0.05 per epoch.
Gruda has a fixed supply of 10 million GRUDA tokens, distributed over 36 months:
Minted_month = 120,000 × 10^8 GRUDA
Reward rates:
R_u = min(Points × Rate, 100 × 10^8)
Fee = (Amount × 5) / 1000
NFT rewards at thresholds: 100, 444, 1727, 5001, 10000, 25000, 50000, 100000, 250000. Bonus: 10,000 × 10^8 GRUDA.
GBuX = GRUDA × 100, Packs = GBuX / 100
Gruda leverages Polygon’s EVM-compatible infrastructure, with smart contracts for token management, cross-chain bridging, and Nexus Nemesis. The SDK supports wallet, token, and NFT operations.
GPU mining requires verified renewable energy, reducing environmental impact.
