What Is A Benefit Of A Multi-Party System In Blockchain

Today’s world is witnessing unprecedented amounts of data being generated by people and machines. This data or information will need to be processed, which may require artificial intelligence and machine learning techniques. The majority of this information will be gathered from all sorts of sources, including individuals, businesses, governments, etc.

Furthermore, this data must be processed and exchanged between several organizations. Sharing data amongst several organizations creates the possibility of hacking, resulting in data loss, potential internet dissemination, and illegal sales. Additionally, trust and privacy are important concerns when multiple organizations must share information. In order to obtain helpful insights, counterparties wish to keep their data private while also gaining access to, and processing, data from other counterparties.

So, how can any party share and handle data while keeping it private at the same time?

 Here comes a solution in Multi-Party Computation-Based Cryptography.

What Is Multi-Party Systems?

Multi-party systems provide more options and enable a wider range of viewpoints to be voiced. A multi-party system precludes a single party’s leadership from unchallenged control of a single legislative chamber. From a data or process perspective, inter-organizational business procedures facilitate interactions between organizations and entities by utilizing multi-party systems. In a multi-party system, stakeholders engage for mutual commercial success, yet they may lack trust. Stakeholders communicate via a variety of mechanisms and hold fragmented or duplicated copies of data. 

Individuals and organizations can share data via multiparty systems in order to enhance efficiency and create new revenue models. Blockchain Technology, distributed ledgers, distributed databases, tokenization, and other technologies and capabilities are some of them.

How Does A Multi-Party System Work?

Data used as input for computation in Multi-Party Computing (MPC) is separated into chunks and “masked” by adding random integers using a cryptographic function. The pieces are then transferred to other servers, which never see the original data from the organization and simply compare the encoded amounts. Even if the underlying data is unknown, the servers are able to perform computations on the encoded amount in such a way as to produce the required results with certainty. It demonstrates how MPC enables organizations to collaborate without having access to each other’s confidential information.

Correctness, greater privacy, input independence, fairness, and guaranteed output delivery are all features of Multi-Party computation.

How Multi-Party System and Blockchain are Connected?

Blockchain is a database system that stores and records data in a way that allows different companies and individuals to securely share real-time access to the same data while minimizing security, privacy, and control concerns. This capacity opens up entirely new perspectives on how to alter processes, drive robustness across complex networks like supply chains, facilitate trust, authenticate people’s and objects’ digital identities, and develop new income models. 

Public-key cryptography, or the usage of pairs of public and private keys in a cryptographic system, is used extensively in the blockchain.

Public keys in public-key cryptography can be shared widely, but private keys are only known by the key’s owner. The owner of a private key can create a digital signature and sign a transaction with it. Anyone with access to the public key can confirm that the communication was sent by the private key owner. This is used in blockchain to sign transactions, offer evidence of identity, and track asset holdings. Within public-key cryptography and blockchain, private key management is a critical task. If not done correctly, accessing and managing private keys can lead to the loss or theft of digital assets or information, as well as data tampering.

When it comes to handling private keys, Multi-Party computation in the blockchain is incredibly handy.

How Multi-party System in Blockchain Works?

Private keys can be broken into chunks and spread across n number of servers using a Threshold Signature Scheme (TSS), a subset of Multi-Party computation that computes digital signatures in a distributed manner. Because the private key does not need to be rebuilt and may be utilized in a distributed fashion, it never becomes a single point of failure.

When a transaction signature is needed, the n servers will work together to perform a distributed signature creation process among the various parties. This is a Multi-Party computation protocol that is used to sign the transaction.

The private keys are never saved together in this procedure, so even if a potential attacker successfully hacks one of the parties, they don’t have access to the entire information.

Interoperability with TSS is being enabled by companies like VMware for the smart contract signing, digital asset transfer signing, and key management services.

What are the Advantages of a Multi-Party System?

If you want to alter your business, you’ll need to collaborate, coordinate, and coinvent with your ecosystem to drive change at an industry level. And multi-party systems will become an increasingly important enabler of ecosystem collaboration. These systems, which include blockchain, distributed ledgers, distributed databases, tokenization, and other technologies and capabilities, allow individuals and organizations to share data in a way that improves efficiency, increases sustainability, and aids in the development of new business and revenue models.

It helps you to focus on

  • Recognize which platforms your company’s consumers and customers used the most in the previous year.
  • Look for ways to collaborate to create one-of-a-kind digital products.
  • Keep up with the multiparty systems that are cropping up in your industry, and start weighing the benefits of participation.
  • Consider how technologies can help with better cooperation and supply chain responsiveness outside of the organization’s borders.
  • Connect virtually every step and piece of data in the source-to-pay process.
  • Network for suppliers. By cutting sales costs, finding new consumers who are ready to buy, or knowing when you’ll be paid, you can shorten the sales cycle.

What are the Applications of Multi-Party in the Blockchain?

MPC’s use in blockchain for digitally signing transactions is just one of the many applications for this technology. Many of the aforementioned firms are attempting to mix MPC and blockchain in novel ways.

  1. MPC can be used by large digital asset custodians like Fidelity, Coinbase to offer evidence of the existence of private funds without divulging specifics or balances. A particular transaction might be signed by regulators, clients, and compliance managers, for example, to demonstrate the existence of private funds.
  2. BuzzShow Network is the decentralized video media sharing platform that is rewarding each of its users with “Goldies”, the network’s utility token for watching, sharing, uploading, and curating videos. The platform’s aim is to distribute revenue equally to all of its users of the platform depending on their contribution.
  3. Amazon Web Services and Google Cloud could use MPC to offer “Security as a Service” models, potentially leading to plug-and-play MPCs.
  4. MPC could potentially be used to calculate medical data for diagnostics without disclosing data to third-party model providers.

Concluding Note

The business environment is more challenging than ever before, yet the opportunities are numerous. A successful deployment of MPC in the future could allow organizations to share data while keeping it private at the same time. In addition, MPC would allow the safe protection of assets, improve security, efficiency, and the overall user experience.

And as data grows exponentially around the world, MPC may be the solution we need to analyze data without sacrificing privacy.
