Hedera Hashgraph Development Company

Hedera is a decentralized ledger that is openly available to the public and was built from the ground up to accommodate web-scale applications both new and old. We make use of a number of different distributed ledger technologies, but one of the most important is Hedera Hashgraph. This allows us to create enterprise-level decentralized apps that are scalable, trustworthy, and efficient. Hedera Hashgraph uses distributed ledger technology to offer an innovative, dependable, and secure solution for conducting online transactions that are unaffected by third parties. Systems that are based on Hedera Hashgraph are able to easily solve issues of stability, security, performance, governance, and regulatory compliance.

Tokenized Assets

Tokenized Assets

Hedera Hashgraph development services can tokenize any asset, including tangible or intangible items, government bonds, and other assets, using the ERC standard. It is straightforward to upgrade, transfer, and mint digital tokens. EvaCodes developers who construct decentralized apps on the Hedera Hashgraph platform, provide superior Hedera token services.

Why Hedera Hashgraph?

Hedera Hashgraph makes it possible for people and companies who do not know or trust one another to work together quickly, inexpensively, and reliably. It results in more favorable technical environments for business processes. Public distributed ledgers make it possible to generate and exchange values, provide proof of identity, verify and authenticate significant data, and do much more. It is an alternative to the blockchain. These benefits stem from the underlying Hashgraph consensus algorithm, which forms the bedrock of the Hedera Hashgraph platform. Hedera is unique in that it achieves the same results as distributed universal blockchains (such as Bitcoin or Ethereum), but in a manner that is faster, fairer, and more energy-efficient, stable, and secure.


Utilizing fair access, ordering, and timestamps provides protection against nodes that have the potential to influence or alter the sequence in which transactions take place.


The Byzantine Fault Tolerance Algorithm makes it difficult for users and cybercriminals to record fraudulent transactions on the ledger. Thanks to the Hash, it is also immune to DDoS attacks and other system attacks.


The Hashgraph distributed consensus algorithm underpins the Hedera Hashgraph distributed ledger technology. This consensus approach can complete a million transactions per second. Hedera Hashgraph's high throughput makes it a great choice for large organizations that conduct high volumes of transactions.


We are working on the peer-to-peer network procedure for digital communication to be combined with virtual voting in order to reach a general work agreement in a shorter amount of time by avoiding Proof Of Work (PoW)

We can integrate your app with Hedera Hashgraph Network with a help of:

Corda Plugin

In conjunction with Corda with Hedera Consensus Service, we have created a public BFT Notary Service.

Hyperledger Plugin

By connecting Hyperledger Fabric and the Hedera Consensus Service, we make it possible for transactions to be ordered and for public verification to take place.

Hedera Hashgraph Microservice

We deploy and prove an application action by utilizing an OSS microservice for Hedera Hashgraph's Cloud Service (HCS) by using a Proof-of-Action Microservice.
