Free text chat application “RoundTable” browser service beta version has been released

EXCo Inc. released a browser service beta version of free text chat application “RoundTable” ( ), specialized in community formation using block chain technology

Along with the rapid expansion of the block chain market, flooding of uncertain information is being seen in any community. The fact that participants are truly owners of that token is an important factor in managing the community.

“RoundTable” uses distributed application technology of Ethernet. The corresponding standard is an ERC 20/223/721 compliant token. With this technology it becomes possible to authenticate that the user really owns the token. By doing this, it becomes possible to eliminate malicious non-owner, and it becomes possible to operate a community with higher quality.

In addition, we are planning various developments applying this application.


1.Utilize the token as an event ticket by taking advantage of the unalterable property of the block chain. In addition, it is possible to create a community for event participants only.

By using tokens as event tickets, you can check the transfer history (transaction). Transmission of tokens by resale can be confirmed in all transactions. If you invalidate a token with a history of transfer, you can use it as a non-resale ticket. In addition, it is possible to create a community with “RoundTable” on condition that you own a ticket. We can add value, such as making a limited community between fans and artists.


2. Utilization as a private salon

RoundTable technology can also be applied to online private salon. We plan to implement key token on RoundTable. This will allow anyone to easily open a secure private salon.


3. In-house development,  creator support business, use RoundTable as a secure collaborative production environment

Scheduled to be used as an application for communication within collaborative production group.

We aim to reach 10 million users of RoundTable users by March 2019. We will continue to develop and expand further services through block chain technology.
