This blockchain ecosystem is still in a period of discovery as different chains and projects look to address issues such as performance, optimization based on the Ethereum architecture (Near, Solana), and the design of blockchain infrastructure for specific scenarios (Filecoin, for decentralized storage as an example).
However, the full potential of what a decentralized digital ecosystem and economy can offer has not truly been reached as a number of basic infrastructure problems still persist. Poor user experience and operating experiences are key among them.
The barrier to entry for users wanting to make use of dApps is extremely high. Using blockchain products means creating wallets that require mnemonics, public and private keys, and every time a user wants to utilize a new chain, the process has to be repeated from scratch. The user experience is inferior to even simple signature verification systems of internet products like fingerprint unlocking, FaceID and direct payment from things like Apple Pay.
Migration costs for app developers are also extremely high. Current app developers are facing performance problems or high gas fees on ETH 1.0. Additionally, there are several other migration cost issues such as facing a new development language which means learning costs and also audit costs. More so, the issue of new customer acquisition cost after app migration comes into play.
Current cross-chain solutions are not addressing foundational problems. Achieving cross chain asset flow is actually not difficult, but it is difficult to make all chains completely cross-chain and functional at the minimum cost.
We are seeing Wrap BTC solutions, and we can also see that Polkadot and Cosmos can complete cross-chain under their own Substrate, Zone, architectures. But, Polkadot’s standards and the assets on the chain issued by Substrate will not really be able to reach the world outside of Polkadot.
The current blockchain ecosystem, surrounded by these problems, means the interaction between blockchains, assets, App products, and users becomes difficult. Without workable interoperability, the blockchain world becomes a lot less potent.
There is a real need for an infrastructure that can solve the problem of interoperability between assets, Apps, and users between multiple chains. And this is where Nervos comes in with the creation of Universal Apps through its suite of developer tools known as Your Universal Passport to Blockchain.
Nervos has built a suite of tools which we have called the Universal Passport. This is our solution to creating a next generation of interoperability that will empower the creation of Universal Applications — Apps that transcend individual blockchains to work seamlessly across every chain in the ecosystem.
In this tool box, we have the Force Bridge, PW Core and Polyjuice.
These three important components of the Universal Passport solve the high barriers to entry, cross-chain circulation of assets, and the premise that dApps do not need to change their code to be truly interoperable.
These components are based on top of the flexible underlying public chain, the Nervos CKB. Through the power of the underlying public chain of Nervos CKB, with Layer2 components, applications, users and assets have access to a blockchain ecosystem that is likened to the internet as we know it today.
