The technical case for ISPAY Chain: heterogeneous cross-chain at scale.
ISPAY Chain connects independent blockchains through a relay chain. Assets move at the protocol level, with BFT consensus, GRANDPA finality, and 100,000 TPS across 100 parachains. Supply is fixed at 1 billion ISPAY tokens, with 80% going to public mining.

Cross-chain infrastructure built for commercial scale.
Thousands of blockchains today run without any connection to each other. ISPAY Chain addresses this with a heterogeneous multi-chain architecture: a relay chain that connects parallel chains (parachains) and moves assets between them at the protocol level, with no bridges or wrappers in the path.
ISPAY Chain uses BFT (Byzantine Fault Tolerant) consensus with GRANDPA finality and a 6-second block time. Each parachain runs 1,000 TPS. With 100 parachains and a relay chain, the network reaches 100,000 TPS. Assets move from source chain to destination chain in native form via MerkleTree-verified cross-chain messaging.
ISPAY has a fixed supply of 1 billion tokens. 80% goes to public mining, open to all participants with no arithmetic threshold. The remaining 20% covers the ecosystem fund, foundation, marketing, and team allocation. The DAO controls 10% of block GAS revenue.
Core concepts from the white paper
Relay chain + parachains
ISPAY Chain is a relay chain that connects parallel blockchains. Parachains submit candidate blocks to relay chain validators. Once finalized, the parablock inherits shared security from the relay chain. No parachain needs its own validator set.
GRANDPA finality, 6-second blocks
GRANDPA (GHOST-based Recursive Ancestor Deriving Prefix Agreement) finalizes chains, not individual blocks. It confirms N blocks per round. 6-second block time. BABE handles block production; GRANDPA handles finality. The two run in parallel.
MerkleTree cross-chain messaging
Cross-chain transactions use MerkleTree verification to prove data integrity. The relay chain moves transactions from the exit queue of one parachain to the entry queue of another. Transactions are tagged with origin chain identifiers to prevent forgery.
Liquidity asset mining
Users pledge any supported parallel chain assets into ISPAY Chain Network. Assets are automatically mapped at 100% value and generate mining rewards without any arithmetic threshold. This is the primary distribution mechanism for the 80% public supply.
DAO governance
ISPAY Chain DAO receives 10% of all block GAS revenue. DAO members are randomly selected from network participants. Proposals for spending from the Ecosystem Fund require a deposit of 5% of the requested amount, returned on approval.
Runes module
ISPAY Chain contains a native Runes module. All transactions route through smart contracts on ISPAY Chain and are confirmed by the full network. This is the infrastructure that ISPAY Swap uses for cross-chain routing without bridge architecture.

The ISPAY Chain White Paper describes the technical architecture of ISPAY Chain: a heterogeneous multi-chain blockchain that connects independent blockchains through a relay chain. It covers consensus (BFT + GRANDPA), cross-chain protocol (MerkleTree verification), token economics (1 billion fixed supply, 80% public mining), and the DAO governance structure.
ISPAY Chain uses BFT (Byzantine Fault Tolerant) consensus combined with a PoS-based validator system. BABE handles block production with 6-second block time. GRANDPA finalizes chains by finding the highest block with sufficient validator votes. With 1,000 validators and groups of 10 per parachain, the probability of a successful attack is statistically negligible.
Each parachain handles 1,000 TPS. With 100 parachains running in parallel on the relay chain, the network reaches 100,000 TPS total. Block time is 6 seconds for both relay chain and parachains.
80% of the 1 billion ISPAY token supply goes to public mining, open to any participant with no arithmetic threshold. 10% goes to the Ecosystem Fund (DAO-controlled), 5% to team incentives, 2.5% to the foundation, and 2.5% to marketing. No private placement or pre-mining for the public supply.
Users pledge any supported parallel chain assets into ISPAY Chain Network. The assets are automatically mapped at 100% value on ISPAY Chain and generate ISPAY mining rewards. The system converts the USD value of the pledged asset into arithmetic power (1 USDT = 1 arithmetic power). Users complete mining without any technical threshold or cost.
The ISPAY Chain DAO receives 10% of all block GAS revenue from the network. DAO members are randomly selected from all network participants. They vote on Ecosystem Fund expenditure proposals. Proposals require a 5% deposit of the requested amount, which is returned on approval and forfeited on rejection. All decisions are executed on-chain.
