Polkadot 2.0
Polkadot ecosystem evolution — Coretime, Agile Coretime, JAM protocol.
Polkadot is a "Layer-0" blockchain evolving toward Polkadot 2.0 — with new Agile Coretime model and JAM protocol.
Polkadot 1.0 model:
•Relay Chain — central hub
•Parachains — specialized chains connected to Relay
•Parachain slot auctions — expensive (millions of DOT)
•Limits who can be a parachain
Polkadot 2.0 — Agile Coretime:
•Instead of parachain slots → buying "coretime"
•Coretime = right to validate blocks
•Bulk Coretime (month) or On-Demand (per block)
•Much cheaper and more flexible
•Small projects can use Polkadot infrastructure
JAM Protocol (2024):
•Join-Accumulate Machine
•Next generation Polkadot
•Smart contract layer + parachain logic
•Competition with Ethereum execution layer
DOT token:
•Staking for consensus (~15% APY)
•Governance voting
•Coretime payment
Ecosystem:
•Acala — DeFi hub on Polkadot
•Moonbeam — EVM compatible parachain
•Astar — multi-VM (EVM + WASM)
•HydraDX — parachain DEX
•Bifrost — liquid staking
Criticism:
•Complex, harder for developers than EVM
•Less traction than Solana or Ethereum L2
