Smart Contracts That Ensures Privacy: Ways In Keeping Smart contract Private and Confidential

Hello everyone, How are you doing, I welcome you again to my blog in the Steem Alliance community.

Today, we will discuss an interesting topic on the platform which will be: Smart Contracts That Ensures Privacy: Ways In Keeping Smart contract Private and Confidential

---

• Introduction

---

One of the main developments in the fast world of blockchain innovation has been the upgrade of smart contracts, it works by giving automatic, straightforward contracts, and these self-executing contracts are provided with the requirements of the automatic transaction encoded into a code on the blockchain.

The very straightforwardness that supports blockchain's security gives a basic resource that is uncommon, i.e. confidentiality and this brings us to the interesting technology in security, securing the smart contracts, wanting to transform the advantages of blockchain technology.

The Security Issue

---

As we all know smart contracts are executed on a public blockchain, where each transaction is identifiable and well-known to all individuals, while confidence and security are ensured by this straightforwardness, important information may likewise be discovered and this is an issue to some.

This level of openness is somehow not an advantage in some blockchain usage, especially those with individual private information, or somehow a company's worth that shouldn't be on the chain.

Therefore, a few interesting methods for safeguarding confidentiality have been created because of the need to cover some specific parts of smart contracts without risking their usage in the blockchain network.

1. Zero-Knowledge Proofs (ZKPs)

---

Zero-knowledge proofs (ZKPs) tend to be one of the most promising ways to deal with the security/confidentiality issue. ZKPs entrust one party to show to another that an exchange/transaction is confirmed without disclosing any other extra information. This shows that an exchange can be confirmed without uncovering the full information despite it been carries out on a smart contract.

ZK-STARKs and ZK-SNARKs are the two most typical ZKPs presently being used. Despite the fact that the two of them have good security arrangements, they are still very different in reality.

ZK-SNARKs: These are great for blockchain applications because of their high productivity and low computational power requirements. They do require a trust arrangement between two parties.

ZK-STARKs: These don't require trust in two parties, but they require more computationally than ZK-SNARKs, it is more scalable for huge applications and can be used in several varieties.

Multi-Party Computation(MPC)

---

Another cryptographic protocol that secures confidentiality is the multi-party computation(MPC), it works by allowing different users to mutually configure a contract while keeping it a secret from the blockchain.

This is more useful in decentralized finance (DeFi) applications, where different users or developers might have to communicate with a contract without revealing their individual financial positions, MPC is particularly helpful in this safe and keeps everyone on the safe side.

Application In Real-World

---

The developments in privacy protection of smart contracts are not simply hypothetical; they are really being used in some real applications, let's look at some here:

Confidential Transactions: For confidentiality, we have some interesting projects like Monero and Zcash, which have shown the usage of private transaction strategies to execute transactions, where transaction amounts or amounts of purchases of an individual are hidden.

Healthcare: We can also advance in healthcare by using the power of blockchain, confidential smart contracts can protect private sharing and handling of clinical information while maintaining patient privacy.

Conclusion

---

The requirement for smart contracts that protect blockchain transactions is always advancing and these developments will play an essential part in making blockchain applications making it safer, private, and generally acceptable as we keep on pushing the limits of its usage in the tech environment.

With the level of progress we have seen from projects like ZKPs, and MPC, I could say we are comfortably moving forward to a future where smart contacts can be powerful and more private for every crypto enthusiast out there.
