POLKADOT: AN INTEROPERABLE, MULTI-CHAIN BLOCKCHAIN INFRASTRUCTURE
Polkadot is an interoperable, multi-chain blockchain infrastructure. It operates as a Layer-0 protocol, enabling specialized blockchains (parachains) to share security and communicate through Cross-Consensus Messaging (XCM). Its core utility includes staking, governance, and purchasing ‘Coretime’ for block production. Significant tokenomics changes in 2026 introduced a hard supply cap and reduced annual DOT issuance, positioning it as a long-term investment focused on shared infrastructure and scalability within the Web3 ecosystem.
