Security features of Mintlayer

Mintlayer uses advanced encryption technology to ensure the security and integrity of its blockchain. Security is reflected in its use of Elliptic Curve Cryptography (ECC), especially the secp256k1 curve. This encryption method, the same as Bitcoin, provides a high level of security while maintaining computational efficiency.

The secp256k1 elliptic curve is a mature standard in blockchain encryption, providing a 256-bit security level, making it computationally infeasible to break with current technology. The use of ECC allows Mintlayer to maintain small key sizes and fast transaction processing while providing a solid security foundation.

On top of that, Mintlayer also integrates Schnorr signatures, which is a more efficient and privacy-focused digital signature scheme than the traditional Elliptic Curve Digital Signature Algorithm (ECDSA). Schnorr signatures have multiple advantages, including signature aggregation, which can combine multiple signatures into one, thereby reducing transaction size, lowering costs, and increasing privacy by making it more difficult to associate multiple signatures with the same user.

By combining secp256k1 and Schnorr signatures, Mintlayer enhances security and privacy. The linear properties of Schnorr signatures support efficient multi-signature schemes, helping decentralized financial applications meet the demand for multi-party approval of transactions, such as multi-signature wallets and decentralized governance structures.

Privacy-focused Token (MLS-02) and Its Impact on DeFi

In the field of decentralized finance, privacy is becoming increasingly important, as transparent transactions may expose sensitive financial information. To address this issue, Mintlayer has developed the MLS-02 token standard, designed specifically to support privacy-focused tokens.

The MLS-02 token is supported by encryption technologies such as zero-knowledge proof (ZKP) to enable confidential transactions. ZKP allows one party to prove a statement as true without revealing any information. In the blockchain environment, ZKP can be used to verify the validity of transactions without exposing detailed information such as amounts or parties involved.

This is important for DeFi because it allows users to maintain privacy while participating in decentralized financial activities. Privacy tokens are particularly useful in certain scenarios, such as corporate finance, sensitive personal transactions, or financial activities subject to regulatory privacy requirements.

Integrating the MLS-02 token into the Mintlayer ecosystem may attract institutional investors who are concerned about exposing sensitive financial data on public blockchains. In addition, privacy-focused tokens can also support new DeFi use cases that are currently difficult to achieve due to transparency issues.

Future Upgrade: Zero Knowledge Proof (ZKP)

Mintlayer's commitment to privacy extends beyond the MLS-02 token. The platform is actively working to integrate zero-knowledge proofs (ZKP) into its infrastructure to enhance the privacy of all types of transactions. ZKP is a powerful encryption tool that allows one party to prove a statement as true without revealing the underlying data.

One widely discussed application of ZKP in blockchain is confidential transactions, where the transfer amount is hidden from the public. While the transaction can still be verified as valid, its detailed information remains confidential, thus bringing significant improvement in user privacy.

Mintlayer's future plans include expanding the use of ZKP to support more advanced privacy features across the network. This may involve the ability to conceal transaction amounts and the identities of parties involved in transactions. These developments could make Mintlayer one of the most privacy-focused platforms in the DeFi space, supporting a variety of confidential financial activities.

Confidential transactions on Mintlayer

Confidentiality is an integral part of the financial system, and Mintlayer meets this need by supporting confidential transactions. Confidential transactions combine encryption technologies such as Schnorr signatures and ZKP.

In confidential transactions, the transfer amount is encrypted using confidential commitments. These commitments are included in the transaction, allowing network participants to verify the validity of the transaction without knowing the actual amount. This ensures transaction confidentiality while maintaining the integrity of the blockchain.

One of the technical challenges in achieving confidential transactions is to ensure that no information about the transaction amount is leaked. To address this issue, Mintlayer uses a type of ZKP called range proofs, which prove that the committed value is within a certain range (for example, the transaction amount is between 0 and 1,000) without revealing the exact value. This ensures the security and verifiability of confidential transactions.

The ability to conduct confidential transactions makes Mintlayer particularly attractive to financial institutions and individuals who require high privacy in transactions. With increasingly strict privacy regulations, the demand for confidential financial solutions may increase.

Decentralized Identity Function

In addition to privacy and confidentiality, Mintlayer is also exploring the integration of decentralized identity (DID) functionality into its platform. DID provides a way for individuals and organizations to establish secure, verifiable identities on the blockchain, independent of centralized institutions.

DID is particularly important in the context of compliance and regulatory requirements. For example, in the case of security tokens, regulatory agencies may require that only verified investors can participate in certain transactions. By using DID, Mintlayer can ensure that token holders comply with these regulations without compromising their privacy. The DID system allows for identity verification on the blockchain without disclosing sensitive personal information.

Mintlayer's DID method could play an important role in decentralized governance. In many blockchain ecosystems, governance is based on token holdings, which can lead to centralization of power. By implementing DID, Mintlayer can introduce more complex governance models that consider not only users' identities and reputations but also their token holdings. This could bring about more democratic and decentralized governance structures that better reflect the interests of the community.
