Sidechain Solutions Announces Lisk Inviter PoC

Sidechain Solutions has announced the development of a proof-of-concept application for the Lisk Blockchain. The announcement, made via one of Lisk’s Discord channels, described Lisk Inviter as “a decentralized application that enables organizations, companies, or other parties to accurately control the entrance conditions of an event, and validate each visitor at the moment they want to check in“. The announcement linked to an article on their website.

In the article, they listed a number of common scenarios where Lisk Inviter might be useful including festivals, concerts, weddings, and social events where restrictions are enforced to create exclusivity for the participants. Private business meetings is another scenario. In the PoC, an account with tokens could represent an identity or membership at any of the aforementioned gatherings. With such an account, “the user can charge up their balance and consume the tokens on additional services”. That’s assuming they’re eligible.

In order for such a concept to work, the host has to create a registerEvent Transaction, which is a custom transaction that includes information about the event’s name, description, entrance fee (optional), start/end date, and list of guests. Therefore, guests will have the event added to their ‘eventsInvited’ assets soon after the host creates the event. The custom transaction’s ID identifies a given event, while a public key is used for a person’s identity. A checkInEvent transaction validates a guest, permitting them to attend an event. This mutates the eventsVisited asset.

The article describes how it all comes together: “When it is time, a user can then go to the event and attempt to check-in. If all the conditions set by the event are met, the person is on the guest list and has not already checked in, entrance is granted. If it is not the correct date, the person has not been invited, has already checked in or does not satisfy any of the other requirements, entrance is denied and a prompt is shown with the reasons why”.

Currently, the passphrase is used for checking in as far as the live demo is concerned. However, a more realistic scenario would probably involve a device with a chip that can be scanned. Scanning will enter the passphrase automatically rather than manually. In addition to the demo, Sidechain Solutions has provided a list of test accounts for the more curious. Find them here: https://github.com/sidechain-solutions/lisk-inviter/blob/master/test-accounts.json.

Sidechain Solutions’ stellardynamic announced the first steps toward “organizing a delegation of available Sidechain node operators”. According to him, these “will be needed as these concepts grow”. He added that Sidechain Solutions hopes “to launch small networks around some of our projects as time goes on. In time, it presents the opportunity to possibly earn tokens on these chains. We also think it will give a head start to anyone who wants to become a reliable Sidechain delegate”.

The group will continue tweaking their proof-of-concept blockchain application in preparation for their LiskJS presentations in Berlin. He also proceeded to whet our appetites by teasing the rollout of a number of services and ideas they have been working on very soon. Stellardynamic noted that “besides taking our own projects to full production scale, producing white-label blockchains is also something we intend to offer. Most of our other services will remain free of charge as always”.

The company is also looking for donations, in order to support their development activities (sidechain_solutions).
