The Hedera Hashgraph project launched the main network, and some people called it to question that it was retrogressive.

The Hedera Hashgraph (hereafter referred to as Hashtu) project, which has received over US$100 million in financing, launched its public network. This project is backed by many large companies, and its highlight is the promise of faster transaction speed than the blockchain. And better scalability.

Since December 2018, a small number of companies and developers have been using the network in test environments. Starting today, anyone can open an account on a hash map or build a decentralized application (dapp). This book is similar to a blockchain, but it uses different mechanisms to achieve the status of the book. consensus.

With the main online line, the HART token system's HBAR token will gradually be released.

It is reported that the first batch of tokens (more than 379 million pieces) will be sent to investors who participated in the project's three rounds (total $124 million) in financing from March 2018 to August 2018.

Another 1.95 million tokens will be issued to project consultants, suppliers and other participants on the first day. In the next 15 years, the total supply of HBAR tokens will be allocated by the management committee of the network.


It is reported that 12 cryptocurrency exchanges and OTC platforms are planning to launch HBAR tokens, including: Algoz, Bitooda, Bering Waters, Bittrex, Galaxy Digital, GSR, Liquid, Okex, OkCoin, OSL, Upbit and Xfutures.

According to Hashtu creators, hash maps work more efficiently than blockchains, making them more suitable for business and business. Specifically, the hash map network can support up to 10,000 transactions per second.

Hedera CEO Mance Harmon said in an interview with foreign media Coindesk:

“This is the first time Hachtu has been tested on a global scale. It is a different data structure and different technologies. It does not look like a blockchain, but it solves similar problems with better security and performance. ""

The most eye-catching is the giant companies behind Hashi, including IBM, Boeing, Deutsche Telekom, Tata, Nomura Securities and banking technology provider FIS.

Identity and doubt are in the same voice

Before the Hashtu main online line, it has captured some fans and critics.

For example, Steve Wilson, principal analyst at Constellation Research, an emerging technology consultancy, is a fan of the Hashto project, saying that Hedera's scale advantage is key to its speed.

Regular blockchains are typically hundreds of gigabytes in size, while hash maps are relatively small because they don't store all transaction history on the ledger (although you can choose to store them on a "mirror" network), wilson Explain that, in addition to speed advantage, Hashtu promises better finality and instant payment.

However, Eric Wall, head of the former blockchain of Cinnober, a Nasdaq-based financial technology provider, said that this speed advantage only applies to certain types of transactions. Wall explained:

"Dapp is a smart contract, and since Hedera's current smart contract trading is limited to 10 strokes per second, it's not going to be more interesting than Ethereum." (Recently he wrote two articles to question the Hedera Hash Project. , which mentions that because the project uses Ethereum virtual machines , this limits the actual TPS of the project).

In addition, Wall also believes that Hedera's consensus service is not new, it said:

“I can't predict what kind of model Hedera will transform in the future, but moving from a model based on economic and game theory guarantees to a credible model is a serious weakening of the system neutral model.”

In addition, the Hedera Hashtu project did not choose to open source as the regular blockchain project. For this, its official website explained:

"The source code for the Hedera network will be open for review, which means anyone can view the code, but this is not open source. Public review can provide transparency while suppressing forks and related instabilities. The Hedera code will be at 1.0. The version (expected to be released in 2020) is open for review. Hedera's sdk, api, mobile wallet, sample application, payment server, node operating software, etc. will all be open source."

Connect to a private network through Consensus Services (HCS)

In addition, Mance Harmon added that since October last year, hundreds of developers have been developing on the Hedera Hashgraph network, which has had 25 dapps before the main network was released.

Despite this, the hash map is still considered to be in beta testing because the network still lacks the Hedera Consensus Service (HCS) and some other features that will be included in version 1.0.

The Hedera Consensus Service (HCS) will act as a link between the private blockchain network and the hash map, which allows transactions from another network to be sorted in time in the heteroda network.

For example, drug development company Certara plans to use HCS to create a “tamper-proof” record of health data transactions, while using a private network like hyperledger to ensure privacy, said Jim Nasr, vice president of technology and innovation at Certara subsidiary Synchogenix. .

And this mechanism seems to have the same function as cross-chain technology.
