Polkadot (DOT) Exchange

About Polkadot

"DOT is the native token of Polkadot, a Layer 0 metaprotocol designed by Dr. Gavin Wood (Ethereum co-founder and inventor of the Solidity programming language) that underlies a network of interconnected Layer 1 blockchains called parachains. The Relay Chain provides shared security and cross-chain interoperability, while each parachain operates as an independent, application-specific blockchain with its own tokens, governance, and execution logic. Polkadot uses a hybrid consensus combining BABE (block production) and GRANDPA (finality) to achieve 6-second block times following the 2024 Async Backing upgrade. The network can autonomously and forklessly update its own codebase through on-chain governance, meaning upgrades happen through community votes rather than hard forks. On March 14, 2026 Polkadot executed the first issuance reduction under a new supply model approved through OpenGov: a permanent hard supply cap of 2.1 billion DOT and a 53.6% reduction in annual issuance."

DOT tokenomics

"DOT's tokenomics were restructured on March 14, 2026 (Pi Day) through OpenGov Referendums #1710 and #1828. Before this change, Polkadot had an uncapped, inflationary supply issuing approximately 120 million DOT annually at 7 to 10% inflation with no maximum supply.
Hard supply cap — 2,100,000,000 DOT (2.1 billion), set by governance in March 2026
Circulating supply — approximately 1.71 billion DOT as of October 2026, according to CoinGecko
Annual issuance (post-March 2026) — approximately 56.88 million DOT, down from 120 million (53.6% reduction); inflation fell to approximately 3.1%
Future reductions — issuance decreases by 13.14% of the remaining supply every two years, following a pi-based formula
Burn mechanisms — 80% of coretime sales revenue plus a portion of transaction fees are burned from circulation, creating deflationary pressure proportional to network usage
DOT utility — governance (voting on network upgrades and treasury spending), staking (securing the Relay Chain; reward rates vary and are published on staking dashboards), and coretime purchases (buying compute resources for parachain operations under the Agile Coretime model)
Institutional access — the 21Shares Polkadot Staking ETF (TDOT) holds DOT and stakes between 40% and 95% of its holdings, according to 21Shares"

What determines DOT's value

"DOT's value proposition in 2026 rests on three developments: the supply cap, which limits the structural inflation of earlier years; Agile Coretime, which lowers barriers for new projects; and the JAM (Join-Accumulate Machine) upgrade roadmap, which aims to position Polkadot as a decentralized supercomputer supporting RISC-V execution environments beyond WebAssembly.

Agile Coretime replaced the rigid parachain auction system where projects locked large amounts of DOT for two-year slots. Developers now buy compute resources on demand, similar to cloud computing pricing. Elastic Scaling (completed in October 2025) allows a parachain to use multiple Relay Chain cores during traffic spikes. The coretime purchase mechanism creates DOT demand that feeds directly into the burn mechanism, linking ecosystem growth to supply reduction."
