First Dapp Starts Experience！Hashgard Bi-weekly Report（9.30–10.13）

5 min readNov 1, 2019

The first version of the public chain virtual machine was developed, and the developers of the Hashgard overseas community have developed the first DAPP based on the Hashgard public chain, which is now starting experience! !

In the future, we will concentrate on the ecological construction of the public chain and hope to join hands with all developers!

What did we do during the past two weeks? Keep reading.

Hashgard News

The first DAPP starts experience in Hashgard public chain

After the SIF-8000 update, developers have been able to build smart contracts and issue DAPP based on the Hashgard public chain testnet. Several developers in Hashgard overseas community independently produced a DAPP based on Hashgard public chain. Currently, the DAPP has been listed on Hashgard wallet.

Hashgard Smart Contract Developer Community established

With the launch of the virtual machine and the improvement of the basic functions of the testnet, developers can already develop based on the Hashgard public chain testnet. In order to allow developers to better discuss and communicate, we have established a developer community of DAPP development!

Hashgard Southeast Asian Community is in full swing

With the acceleration of our Hashgard technology and the increase in GARD trading volume, many Indonesian blockchain investors who are interested in Hashgard have spontaneously established a Hashgard Indonesian community and organized a large number of promotional activities to spread our philosophy!
