WHO WE ARE

Why blockchain

Blockchain introduces a revolutionary approach to data management, diverging from the conventional centralized model. Instead of relying on a small group of stakeholders for data control, Blockchain distributes information across multiple computers, known as nodes, on a decentralized and public network. This transformative shift ensures increased security, data anonymity, tamperproof integrity, and seamless auditability.

This can be achieved due to the unique characteristics of the Blockchain:

Distribution: Blockchain operates on a distributed network comprising numerous nodes. Data stored in the Blockchain is replicated across these nodes, creating unique references that bind each replica.

Encryption: Blockchain employs robust encryption techniques utilizing private and public keys, fortifying data security. Access to the Blockchain for writing purposes is exclusively granted through individual private keys.

Transparency: Blockchain activity remains transparent and auditable, while safeguarding the privacy of individual users. It enables comprehensive visibility into transactions without traceability to specific individuals.

Immutability: Once data is recorded in the blockchain, it becomes immutable, impervious to alterations or deletions. The data’s replication across multiple nodes, coupled with a validation mechanism, ensures tampering attempts on one node are invalidated by others, rendering tampering virtually impossible.

Tokenization: Blockchain represents data as tokens, facilitating seamless transfer, storage, and verification of data integrity and accuracy.

Decentralization: By eliminating the reliance on a central intermediary, Blockchain liberates transactions and rules from single-entity governance, granting participants greater autonomy and trust.

Smart Contracts: Blockchains support smart contracts, empowering participants to establish automated rules for transactions. These self-executing contracts facilitate direct exchanges of tokens between parties, eliminating the need for intermediaries and streamlining processes.

 

Why Choose Blockchain for Your Business?

Blockchain is the perfect choice for businesses engaged in multi-participant transactions. It guarantees transparency, maximizes security, and offers versatile applications across various domains, including payments, logistics, data traceability, smart contracts, voting processes, and approval workflows.

One of the remarkable advantages of Blockchain technology is its ability to significantly reduce verification costs in multi-participant processes. By providing a single, validated data storage location accessible to all participants, Blockchain eliminates the need for individual data updates and validations required by conventional technologies.

Our bespoke blockchain solutions seamlessly integrate into modern applications, combining functionality with a visually appealing and user-friendly interface. We understand the importance of delivering an engaging user experience that both you and your esteemed clientele will appreciate.

If you’re seeking reassurance about the transformative potential of Blockchain technology for your business, contact us today. We are eager to delve into your requirements and discuss how blockchain can revolutionize your operations.

XSynkLogo

DOES YOUR APPLICATION SPEAK BLOCKCHAIN?

XSynk is a translator connecting your applications with the applications of external partners.
Using the blockchain as a common database, XSynk integrates the information you need to share without providing access to your systems.

In a connected economy, organizations need to integrate their systems with multiple stakeholders, each utilizing different technologies. This poses several challenges and XSynk uses Blockchain technology to address these challenges. The Blockchain is a common database, distributed between all the stakeholders, allowing to modify any data only through a process of consensus. Consensus uses advanced cryptographic methods, making it a highly secure platform. Data stored on the blockchain is resistant to unauthorized alterations and provides robust protection against fraud and cyber threats.
Transactions recorded on a blockchain are immutable -much like a book where you can write new pages but you cannot change what is written- ensuring a high level of data integrity and accountability. This is particularly valuable for applications requiring an indisputable audit trail.

XSynk, harnessing blockchain technology, offers numerous advantages for your organisation:

  • Interoperability: Seamlessly integrate your system with multiple partners, each utilizing different technologies.
  • Costs of reconciliation: Sharing the distributed ledger with your external partners voids the efforts and costs of cross-referencing information between different databases.
  • Traceability: Establish a fully traceable chain of goods or services, such as achieving Fair Trade certification, pharmaceuticals productions process, etc.
  • Compliance and Auditing: Simplify compliance with regulatory requirements and auditing processes by providing a transparent and auditable record of transactions and data.

 

With XSynk, we can implement both public and private blockchain solutions, employing encryption or hashing techniques to ensure that only the intended recipients can access and decrypt the data.

With XSynk, you don’t need to write a single line of code and the installation is simple: simply define the database entities and transfer directions (incoming or outgoing) where XSynk should read and write, and XSynk handles the rest.

IdMeLogoFinal

SECURE AGE VERIFICATION WITH PRIVACY

Leveraging blockchain technology and with a focus on privacy and compliance, IdMe provides an anonymous non-transferable token certifying that, depending on the jurisdiction, the user is over a certain age, allowing them to access online age restricted content.

IdMe offers a seamless connection between users and content providers. Users can verify the content of their tokens and reuse the same token to access different platforms.

To generate a non-transferable token without retaining any personal data, IdMe employs a double anonymity protocol, similar to Zero Knowledge Proof encryption, using a certified third-party provider:

  • The third-party provider simply verifies the requested eligibility of the user.
  • IdMe acts as an intermediary between the user and the third-party provider and only receives the validation of the eligibility criteria from the third-party provider.
  • The recipient of the intended use of the token ignores the identity of the owner of the token. They simply know the user has a valid token.
  • The owner of the token has the option to and use it again, as they please, certifying they fulfill the criteria certified by the token.

 

Tailored Verification Systems

Our age verification process is precisely customized to adapt to the unique requirements of different jurisdictions for the access of age restricted content.

Whenever a user connects, we employ only official verification measures accepted in the country of the user, such as document verification, facial recognition, or the use of national digital identity solutions.

ENHANCING ART TRACEABILITY WITH BLOCKCHAIN

Leverage the power of blockchain technology to revolutionize art traceability and authentication. Our customized solutions are designed to ensure transparent and verifiable art transactions, providing a secure and immutable record of ownership, provenance, and transactions. By utilizing blockchain, artists, collectors, and art institutions can benefit from increased trust and authentication in the art market.

With our art traceability solutions, every art piece is assigned a unique digital identity stored on the blockchain. This digital identity contains crucial information such as the artist’s name, creation date, previous owners, and transaction history. These details are securely recorded and cannot be tampered with, providing an unalterable record of the art’s journey.

By leveraging blockchain’s decentralized nature, our solutions eliminate the risks associated with fraudulent art practices, including counterfeiting and unauthorized duplication. The transparent and immutable nature of blockchain ensures that art buyers can verify the authenticity and provenance of artworks, fostering trust and confidence in the market.

Our customized solutions also empower artists by enabling them to protect their intellectual property rights. By securely storing copyright information and digital certificates on the blockchain, artists can establish undeniable proof of ownership and protect their creative works from unauthorized use or plagiarism.
