IOTA is a new technology using the so-called Tangle instead of Blockchain. In IOTA, every transaction approves two previous transactions in the Tangle. This makes IOTA scale proportionally with the number of transactions per second and enables IOTA to be completely fee free. This makes IOTA the perfect fit for the Internet of Things (IoT).

But there are a few concerning issues with MIOTA:

• The kerfuffle with the custom hash function. Many still aren’t convinced it is necessary, even after the dev responses.
• No good GUI wallet and “disappearing” iota after snapshots. Really big issue for newcomers.
• Not handy. Hard to obtain, especially for beginners or newbies.

While Hdac platform will achieve convenience and reliability by using MultiChain and other technologies. It is interesting to note that Hdac will use the products of EYL that will provide quantum random number generation for blockchain to be even safer.

Hdac seamlessly utilising double-blockchain, private and public blockchain, to ensure security and reliability within the network. From private to public and back again, Hdac Hybrid Blockchain is configured as a hidden network with safe tunnelling between a user and device to combat hacks, privacy invasions and external attacks. Mutual authentication between device and user is crucial for a reliable Private Blockchain, which fundamentally will only be practical if it interacts with the Public Blockchain.

Hdac also implements a specific authentication scheme by applying a Quantum Random Number (beginning with our identifiable characters “Hdac”) to eliminate the possibility of hacking.

And what interesting is, the transaction speed per second. Compare to IOTA and even Bitcoin, HDAC can handle more transactions per second:

• 160 tx/sec (in public blokchain)
• 500tx/sec (in private blockchain)
• 1000 tx/sec (HDAC target)

IOTA is good but HDAC is better with real improvements in technology.
