Polkadot (DOT) Giá | Thị trường | Thông tin dự án | LBank
Polkadot Polkadot is a heterogeneous multi‑chain technology. It consists of many parachains with potentially differing characteristics which can make it easier to achieve anonymity or formal verification. Transactions can be spread out across the chains, allowing many more to be processed in the same period of time. Polkadot ensures that each of these blockchains remains secure and that any dealings between them are faithfully executed. Specialised parachains called bridges can be created to link independent chains. On approximately August 21st at 16:45 UTC (block number 1,248,328), the DOT token underwent a redenomination from its original sale. New DOT are 100x smaller than DOT (old). Therefore, your DOT balance is 100x higher and the price per DOT is 100x lower. The percentage of the DOT you own relative to total supply is unchanged. This will not affect the total value of your position. See the Polkadot blog post for more information

Dự đoán giá
Giải thích về đường trung bình động: Đường trung bình động là đường nối giá trung bình trong một khoảng thời gian, dùng để làm mượt biến động giá và xác định hướng xu hướng. Giá nằm trên đường trung bình thường là xu hướng tăng, nằm dưới là xu hướng giảm. Đường trung bình ngắn hạn cắt lên trên đường trung bình dài hạn là giao cắt vàng (tăng giá), cắt xuống dưới là giao cắt tử thần (giảm giá). Sắp xếp tăng giá (ngắn hạn > trung hạn > dài hạn) cho thấy xu hướng tăng mạnh, sắp xếp giảm giá thì ngược lại.

Polkadot (DOT) Câu hỏi thường gặp
Polkadot is a Layer 0 meta-protocol designed to connect various specialized blockchains (parachains), enabling secure and trustless data and asset transfers across them. This framework aims to build a scalable and interoperable multi-chain ecosystem. It was co-founded by Dr. Gavin Wood (co-founder of Ethereum), Robert Habermeier, and Peter Czaban, with development supported by the Web3 Foundation.
Polkadot operates with a central Relay Chain that provides shared security and consensus, but does not support smart contracts directly. Instead, specialized Parachains connect to the Relay Chain to leverage this security and achieve interoperability, hosting smart contract functionality (e.g., via Moonbeam or Astar). With Polkadot 2.0, the JAM protocol is bringing native smart contract focus. Unlike single-chain networks, Polkadot's throughput scales with its parachains, designed to process thousands of transactions per second across the entire ecosystem.
The DOT token serves multiple core functions: Governance, allowing holders to vote on network upgrades via OpenGov; Staking, where users bond DOT to nominate validators and secure the network, earning rewards; and Coretime (formerly Bonding), used to purchase blockspace for parachains in the new Agile Coretime model. The network uses an inflationary model (around 10% annually) to incentivize staking, with no hard cap on supply. A redenomination occurred in August 2020, changing 1 Old DOT to 100 New DOT purely for manageability.
Users can earn rewards by staking DOT, primarily through nominating validators in Polkadot's Nominated Proof-of-Stake (NPoS) system. While direct nomination on the Relay Chain typically requires a higher minimum (dynamically changing, often hundreds of DOT), Nomination Pools allow staking with as little as 1 DOT. It's crucial to maintain an 'active' account by keeping at least 1 DOT (the Existential Deposit) to avoid account deactivation. Be aware that validators and their nominators can be 'slashed' (lose DOT) if the validator misbehaves, ensuring network security.
Polkadot 2.0 encompasses significant upgrades like Asynchronous Backing and Agile Coretime, transitioning from rigid parachain auctions to a flexible, cloud-like model for blockspace. This allows projects to purchase 'processing power' (Coretime) on demand. A major future focus is the JAM (Join-Accumulate Machine) protocol, envisioned to replace the current Relay Chain with a high-performance 'global computer' capable of supporting any service, not just specialized blockchains, making the ecosystem more adaptable and powerful.
