Please keep in mind that while the platform is fully operational, this launch marks a Beta phase designed to optimize the DEX based on real-world use and continuous feedback.


Getting Started with zkCross

Joining zkCross as an early adopter is straightforward. 

Remember, to pay for transaction fees on Partisia Blockchain, you have the flexibility to use BYOC assets directly or wrap MPC (via Koala Wallet and the Browser.) Koala Wallet’s guide on bridging and gas or paying for transaction fees on Partisia Blockchain is available here.

Here’s how you can get started with Koala Wallet:

  1. Download Koala Wallet
  2. Create an account and securely store your 24-word seed phrase (your account backup).
  3. Get some MPC or BYOC assets into your account*
  4. Start trading on zkCrossDEX

 

*You can onboard assets into Partisia Blockchain in multiple ways currently:

  • Withdraw MPC or BYOC assets from supported exchanges. BYOC assets would be required to be withdrawn to supported chains, eg BNB on BSC or POL on Polygon
  • Obtain BYOC or MPC onchain, directly through zkCross cross-chain swaps, Koala Wallet bridge (BYOC only at the moment) or various other routes. For example, one could purchase BNB on BSC and then bridge that into Partisia Blockchain. Any BYOC asset can be used for transaction fees on Partisia.

We’re working with zkCross and other relevant partners on increasing accessibility and liquidity. Please bare in mind that high volume transactions will result in high slippage. We highly encourage our community to provide liquidity across the core pairs to support increase depth across zkCrossDEX.

Interoperability Challenges in Blockchain and PBC’s Solution

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…

Figure 1: Amusement Park and Similarities to Blockchain Industry

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?

Figure 2: Historical Outcomes in Platform Competition

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.

Figure 5: Design to call PBC as a service

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.

Creating Privacy Around Blockchain Settlements

Creating Privacy Around Blockchain Settlements

Ledgers are the primary ways settlements are recorded. The first double bookkeeping ledger system was recorded in use as far back as the 1300s. It is still the de-facto system used today to record transactions between entities.

Fast forward to 2008. Satoshi Nakamoto (pseudonym) was frustrated with the corruption due to the lack of transparency and centralized control of the traditional system. He proposed a transparent distributed ledger system that was immutable as a system of recording transactions. Thus Bitcoin was born.

But with all new systems, there is always room for improvements.

As discussed in our previous articles, full transparency does not solve the problem of building trust. In fact, privacy is a requirement in any trust relationship. For example, nobody would trust a credit card provider that revealed every purchase cardholders made just by someone having their credit card number. In a traditional blockchain space, every transaction is written in a public ledger. It would only require matching a wallet address to a name to see the full history of their transactions.

How can you have a blockchain that privatizes transactions and has enough flexibility to analyze and compute the data? Through integrating a proven technology into a scalable and interoperable blockchain.

Developers can pick and choose which part of the data in the blockchain needs to be private and which can be public. All thanks to the Partisia Blockchain’s programmable MPC. A layer of governance can be enabled around the private data to allow for computation and access to select individuals. Those who access the data can also be audited transparently.

Now, even if someone has your credit card details, they will not be able to see your purchase history and your spending. If needed, a governance model can be created to ensure auditability and traceability to the system.

The importance is evident in our partnership with the International Committee of the Red Cross (ICRC). We partnered with the ICRC to build out a program for distributing aid through blockchain. One of their key requirements was privacy of the aid recipients. As they are a very unique organization, one of their key principles is in confidentiality and bilateral dialogue. The ICRC mainly operates in conflict zones and lack of privacy can mean life or death.

ICRC was able to solve their key challenge of privatizing the transactions of the stable tokens in the ecosystem thanks to Partisia Blockchain’s MPC. As shown above, the deposit of the funds from ICRC is kept private. As a result, transfers between the users are anonymous. To learn more, please watch our video of the overview of the solution here.

As blockchains become more prevalent, the need for privacy will continue to grow and take center stage. Various projects are already being built with private settlements in mind. We continue to speak with many organizations who prioritize the need for privacy in a blockchain solution.
