Hdac Get ready for faster, safer transactions.

We are creating a reliable ecosystem in which transaction services run across the general Hdac space and the private blockchains by configuring the private and public blockchains so they are interconnected.
Blockchain and IoT
Blockchain is a technology where many entities can share and manage everybody’s transaction accounts. The IoT refers to technologies and services that connect all things based on the Internet and communicate information between people and devices.
Integration Between Blockchain Networks
As initial blockchain technology is becoming popular due to its features of decentralization, transparency, usability, and reliability, the applicability of the blockchain is expanding across industries such as cryptocurrency, attendance verification, forecast markets, and international finance.

Our Hdac Platform

Transaction Innovation

Many devices on the blockchain are operated by an IoT contract. IoT contracts not only control devices, access, and help communicate between devices, but also assure anonymity, with all transactions recorded in the ledger.

Privacy is one of the biggest challenges facing IoT, so Hdac configures unique Hdac Platform networks for all types of users. Our platform acts to support payments with state-of-the-art hardware wallets immune to viruses. From private to public and back again, our Hdac Platform is configured as a hidden network with safe tunneling between a user and device to combat hacks, privacy invasions and external attacks. Remember, mutual authentication between devices and users is crucial for a reliable private blockchain, which fundamentally will only be practical if it interacts with the public blockchain.

The technology can be applied to smart factories, smart homes, smart buildings, and various industries. Also, M2M transaction for mutual contracts and operation between IoT devices are implemented to bring a platform where rational consumptions and transactions are possible. It is also where we can implement Transaction Innovation.

Eco-friendly, Fair Mining

We provide equitable, energy efficient opportunities.

Let’s break this down: To create a block you must mine.
A general blockchain consensus algorithm consists of Proof of Work (PoW) and Proof of Stake (PoS). This method, however, often results in excessive and unnecessary usage (PoW) while concentrated mining creates an unequal share among participants with a select few stakeholders controlling the network (PoS).

Our ePoW aims to eradicate power inefficiency and mining monopoly. By applying a block window concept, we overcome common limitations and welcome an extended group of stakeholders within an evenly distributed, decentralized network.

Connecting Chains

We seamlessly link public and private blockchains.

Firstly, it’s crucial to interpret a node as any device connecting to the blockchain network. Now, a public blockchain is open. A private blockchain requires an invitation. As a result, the “permissioned” nature of the latter means it’s unlikely to be accessed by nodes as freely as the former. Problem created.

Cue Bridge Node, an intermediary which contains key configuration information in order to link the two. Problem solved.

Enhanced Device Security

With great blockchain comes great responsibility. Hdac keeps you safe.

As with every digital transaction, cyber criminals loom. We aim to stop them. In fact, we don’t even intend to give them a chance.

Recent cases have identified vulnerability with pseudo random numbers generated when creating your wallet addresses and private and public keys.

Hdac implements a specific authentication scheme by applying a quantum random number (beginning with our identifiable characters “Hdac”) to eliminate the possibility of hacking.
