Polkadot (DOT) 価格 — DOTを購入・スワップ

The story behind Polkadot

Gavin Wood helped write Ethereum's original code before concluding, in a 2016 paper, that one chain trying to do everything was the wrong design — better to let many specialised chains share security through a common relay layer. Polkadot's relay chain launched in May 2020, and the first parachain slot auctions followed in late 2021, with projects locking up DOT for months at a time to win a place.

That rigid auction model eventually gave way to more flexible 'coretime' purchases, and governance moved fully on-chain under OpenGov, retiring the council-based system Polkadot started with.

What DOT is used for

You would stake DOT through nominated proof-of-stake to help secure the relay chain and earn a share of network rewards for it, and you can vote directly on treasury spending and protocol changes through OpenGov rather than delegating that judgment to a council. Coretime purchases, paid in DOT, are what let a parachain actually access the network's shared security and cross-chain messaging.

Polkadot in the market today

Polkadot remains one of the best-known interoperability projects and controls a substantial on-chain treasury to fund its own ecosystem. It competes for the same cross-chain role as Cosmos, LayerZero and the fast-growing web of Ethereum rollups, and that crowded field has diluted the first-mover advantage Polkadot held when parachain auctions first launched.
