Interoperability Challenges in Blockchain and PBC’s Solution

Have you ever taken a trip to an amusement park? Then you are probably familiar with “amusement park dollars”. The park encouraging you to exchange your native currency to “amusement park” dollars because the only thing that is accepted in that amusement park is the currency of the amusement park. And of course, those amusement park dollars are not good anywhere else except in that park.

This is similar to how the public blockchain industry’s tokenomics works. If you want to play in the Solana ecosystem, you have to have the SOL token. Same with Cardano, where you need to pay using ADA. Theta is TFUEL, etc. The entire ecosystem model revolves around their specific currency.

And like amusement parks, every blockchain is in competition with each other. “We’re cheaper. We’re faster. We’re the easiest to develop on.” So on and so on…

In fact this “competition with each other” scenario has been seen throughout history. And it’s quite interesting to see, historically, who has been the winners in these types of competitions. VHS vs Beta in the 70’s, The desktop wars in the 80s, Ethernet vs Token Ring in the 90’s, search engine wars in the 2000’s, and the streaming war that is currently ongoing. And in almost all cases, the winners in these “wars” was the one who was collaborating rather than competing with others.

So the big question is….. Who is going to win the L1 public blockchain wars?

As mentioned above, the current state of the public “blockchain wars” is all about competing with everyone. The combination of every chain saying they are faster and cheaper, with the silo’ed tokenomic model of each chain forcing users to spend only in their currency locks every dApp in their own ecosystem. This is why interoperability has become one of the biggest topics in the industry.

But can we do it differently?

One of Partisia Blockchains core principles is interoperability. This is because our vision is to enable anyone to create solutions that help establish trust and foster collaboration and this means having an architecture that supports interoperability.

Figure 3: Collaboration, Not Competition

So in this regard Partisia Blockchain created a platform from scratch. And following the vision and principles we are adhering to, we created the concept of Bring Your Own Coin (BYOC).

BYOC basically means the users of the chain can pay for using apps developed on PBC using the coin they are most comfortable with. Or in other words, the gas payment on our chain is other liquid coins. This allows for the following possible features.

  • Flexibility of the developers to create their apps and open up their ecosystem to all different type of token holders
  • Use the unique bridge for different types of use cases between chains, such as swaps, or transfer of data alongside account information between chains.
  • Allow for our general multiparty computation infrastructure as a service. dApps built on other chains can now use our MPC technology without needing to port their application over into our chain
  • Stable fee structure — price of the underlying asset does not change how much you pay in gas. It is always structured in a flat USD amount, allowing businesses to properly forecast their financial projections.

The Hermes bridge is a double-entry bookkeeping system securing the bridged asset through our MPC multi-sig oracle key. Currently supporting Ethereum, BNB and Polygon USDC, our roadmap includes others like bitcoin, ADA, XTZ and allows for simple integration to all other EVM compatible tokens. This interoperability and gas payment model opens up a variety of interesting use cases, such as the ability for users to interact with any dApp using their own currency of choice.

Our MPC-as-a-Service is also a unique feature of Partisia Blockchain. Our core vision is empowering anyone to be able to utilize our MPC services and to achieve this vision, we designed an architecture that allows anyone to call the blockchain, regardless of where their core app is built. Whether it is a traditional Web2 or a Web3 application that is built on a different chain, both can call Partisia Blockchain and compute using secret inputs without needing to port their entire application stack over to Partisia Blockchain.

By creating a programming language that allows for developers to use MPC in a generic way, and combining it with a unique interoperability and a scalability architecture, Partisia Blockchain Foundation has made the creation of applications that can harness the power of MPC for different use cases a possibility. Partisia has been at the forefront of providing private MPC solutions since 2008. And by layering this technology on top of an interoperable and scalable blockchain, Partisia Blockchain is now paving the way for anyone to create solutions that can balance privacy and transparency to build trust.
