Breaking the value island of advertising industry,JAMBO joins Polkadot ecology
Due to the lack of mutual trust among stakeholders in the traditional advertising industry, there are some non value parts, such as advertising verification, data monitoring, and advertising interception. The high trust cost leads to the transfer of interests of all parties. On the one hand, advertisers have high user acquisition costs. ; On the other hand, small and medium-sized media have no way of parrying the monopoly of large enterprises; at the same time, users are disturbed by advertisements and the user experience is poor.
Blockchain technology can solve some of the traditional integrity problems, but there are isolated islands of value between chains, and smooth interaction cannot be achieved. The current disadvantages of distributed blockchain traffic are very obvious. In the past, due to the lack of technical support and closed-loop design of traffic, not only the effective increment of blockchain traffic could not be opened smoothly, but also the vast majority of the stock traffic could not be imported into the blockchain target projects, causing ecological development to become scattered and disorderly.
We use Substrate to build our own application chain. Polkadot plus Substrate can meet all the five basic requirements. Modular functions are the biggest highlight of Substrate. As long as you use Substrate to develop a blockchain, you will enjoy the loosely coupled modules. The following figure shows the division of modules by Substrate.
The interoperability of data and assets requires the use of Polkadot’s functions. As we can see from the Polkadot architecture diagram, as long as we are connected to the Polkadot slot, the validator node of the relay chain can verify the data and assets to open up with other parachains connected to the slot. Of course, we can also communicate with the existing main blockchain through the connection bridge. This connectivity solution can also be expanded through the second-layer relay chain.
Transaction also requires scalability for an application. When a parachain cannot support the transaction of a certain application chain, new parachains can be used to continuously expand the transaction. Therefore, in the ecology of Polkadot plus the rapid development of Substrate, developers can easily meet the ever-expanding demand. Of course, when a relay chain cannot meet the demand, multi-layer relays can also be used to continuously expand the number of parachains.
Substrate’s framework is naturally friendly to governance. The biggest problem of blockchain development so far is the source of credit. Blockchain is said naturally trustworthy, which is correct to a certain extent. It is indeed verifiable, If, like Ethereum, it cannot be changed once the contract is released. As long as it is verifiable, it is trustworthy. No one needs to trust the person who issued the contract because they can verify it themselves. However, the problem is that the contract cannot be iteratively upgraded. Blockchain products that have been launched definitely evolve iteratively, and iterative upgrades should be realized. As a launched application chain service, the system certainly needs to achieve the characteristics of iterative upgrade. However, by doing so, it needs to solve the problem of trust and disallow unauthorized upgrade by the developer. It is absolutely a bad idea if we have to trust the developer unconditionally. Upgrade requires a governance structure, which combines on-chain and off-chain governance, so that the application chain can iteratively adapt to market development needs.
Every developer needs to consider on-demand security distribution. The cost of absolute security is high. Relative security is good enough for application chains in certain scenarios. The security of the Polkadot ecosystem can be provided through its own consensus mechanism, or provided through Polkadot’s consensus mechanism. After access to the slot, you do not need to maintain the verification node by yourself, which enables you to focus on application and function realization.
