THE

DIGITAL BLOCKCHAIN AGENCY

SHAPING THE DIGITAL FUTURE

Blockchain technology achieves decentralized security and trust in several ways. To begin with, new blocks are always stored linearly and chronologically. That is, they are always added to the “end” of the blockchain. After a block has been added to the end of the blockchain, previous blocks cannot be changed.

ECOSYSTEM KNOWLEDGE & SKILLS

The knowledge of different standards or ecosystem work is essential for a blockchain engineer.
Below are some programming languages that are necessary in building and optimizing the underlying infrastructure of blockchain systems.

WHO WE ARE

Blockchain technology was first outlined in 1991 by Stuart Haber and W. Scott Stornetta, two researchers who wanted to implement a system where document timestamps could not be tampered with. Two decades later, blockchain had its first real-world application. Our team and experience reaches back a decade and gives us

a head start within this fast growing

technology.

OUR WORK

Blockchain for business is built on a shared, immutable ledger that is permissioned to increase efficiency among trusted partners.

Cryptography is key for the blockchain to maintain a secure, transparent, and tamper-resistant record of transactions. Our expertise is to provide this to our clients and optimize multiparty workflows around trusted, permissioned data and accelerate performance across your value chain with blockchain applications.

Consensus: Shared ledgers are updated only after the transaction is validated by all relevant participants involved.

Replication: Once a block — the record of an event — is approved, it is automatically created across the ledgers for all participants in that channel. Every network partner sees and shares a single “trusted reality”of the transactions.

Immutability: More blocks can be added, but not

removed, so there is a permanent record of every transaction, which increases trust among thestakeholders.

Security: Only authorized entities are allowed to create blocks and access them. Only trusted partners are given access permission.

WHAT WE DO

Blockchain is a shared tamper-proof ledger that simplifies the recording of transactions and asset accounting in a business network. Sharing supply chain data is good for business. Sharing data on an enterprise blockchain platform adds greater functionality because you decide who can see it. With a supply chain transparency solution and management system, you can create immutability with a distributed and shared ledger to transact with your supply chain partners in a more trusted and efficient way.

CRYPTOGRAPHY

The developer knows how cryptography and data structures fit into the blockchain structure. A blockchain developer is a software engineer who develops a blockchain network or decentralized application for that network.

The knowledge of cryptography helps blockchain engineers ensure data encryption without any loopholes.

BLOCKCHAIN ARCH.

To implement effective consensus protocols and how to build decentralized applications and smart contracts. A blockchain developer is also proficient in the programming languages used to create these components.

Our Blockchain engineers have an exceptional understanding of blockchain architecture and its working with consensus and hash functions.

WEB DEVELOPMENT

Comprehensive understanding of the technologies that support web applications. Blockchain web applications must be efficient and user-friendly.
The understanding of different blockchain development tools (MetaMask, Remix, Truffle, etc.) acts as catalysts to create solutions at a faster rate.
