A Polkadot Parachain
A Polkadot Parachain
Mosaic Chain isn't a standalone blockchain. It's a Polkadot parachain—which means it plugs directly into Polkadot's relay chain and inherits security from around 1,000 relay chain validators securing the entire Polkadot network.
This isn't just a technical detail. It's the foundation of how Mosaic Chain delivers speed, security, and interoperability without compromise.
What's a Parachain?
Polkadot is a sharded network. Instead of one blockchain trying to do everything, Polkadot connects multiple specialized blockchains—called parachains—that run in parallel.
Each parachain handles its own transactions and logic. Polkadot's relay chain coordinates everything, finalizes blocks, and provides shared security.
Mosaic Chain is one of these parachains. We handle financial transactions. Polkadot handles security and cross-chain communication.
Shared Security: Two Layers of Validation
Mosaic Chain will have over 2,000 validators (when fully onboarded) running our DPoS consensus mechanism. 200 validators are selected each session (every hour) to produce blocks and validate transactions on Mosaic Chain.
But that's only the first layer.
After Mosaic Chain validators produce and validate blocks, those blocks are sent to Polkadot's relay chain validators (~1,000 validators) for finalization. Polkadot validators review the blocks, check their validity, and finalize them on the relay chain.
This two-layer validation process means:
Mosaic Chain validators handle block production and initial validation (via DPoS)
Polkadot relay chain validators provide final validation and shared security
In Polkadot terminology, Mosaic Chain validators are technically called collators—they collect and batch transactions, then send them to Polkadot's relay chain for finalization.
This double-checking ensures Mosaic Chain benefits from both:
Our own decentralized validator set (2,000+ validators, NFT-based participation)
Polkadot's economic security (~1,000 relay chain validators with billions in staked DOT)
You get the best of both worlds: a large, decentralized validator set on Mosaic Chain, plus the security guarantee of Polkadot's relay chain.
Forkless Upgrades
Blockchain upgrades are usually painful. On most chains, upgrades require hard forks—validators download new software, coordinate off-chain, and hope the network doesn't split.
Polkadot parachains, including Mosaic Chain, use runtime upgrades instead.
The blockchain's logic is stored on-chain. When an upgrade happens, validators automatically switch to the new runtime. No hard fork. No downtime. No coordination chaos.
Mosaic Chain can roll out new features, optimizations, and fixes seamlessly—without disrupting users or validators.
Why Polkadot?
We chose Polkadot because it's the best available technology for building a financial blockchain.
Shared security from day one—2,000+ Mosaic validators plus 1,000 Polkadot relay chain validators
Native interoperability via XCM
Horizontal scalability through parachains
Forkless upgrades for seamless evolution
Substrate framework—modular, extensible, battle-tested
Mosaic Chain is built on Substrate, connected to Polkadot as a parachain, and designed to leverage everything Polkadot offers.
We're not reinventing the wheel. We're using the best infrastructure available and focusing on what matters: building a blockchain optimized for financial applications.
