On August 16th, TokenGazer released the Polkadot in-depth research report: Polkadot's founding team has extensive experience in blockchain development and operation, and has a deep understanding of the limitations and development direction of the public chain. Based on this, Polkadot's positioning is also very clear, addressing scalability and isolation issues. Polkadot solves this problem by adopting a heterogeneous multi-chain architecture—parallel chains can meet the specific needs of building applications over time, and the relay chain building base layer coordinates parallel chains. Polkadot's design on the economic model is also relatively reasonable. The economic incentives for certifiers, nominees, collectors, and phishers make Polkadot's network fully effective. At the same time, DOT has more usage scenarios under the economic model, including the payment of cross-chain transaction fees, parallel leasing lease mortgages, mortgages for verifiers and nominees participating in the consensus mechanism, and ballots in decentralized governance. – The use of diversity can form a relatively stable value support for DOT. But compared to similar projects, the valuation of Polkadot's $1.2 billion may be overestimated.
