In what could be one of the year's most talked-about launches, a cryptocurrency project called Augur may soon invite its community to bet against its success.
Created by the Forecast Foundation in 2015, the crowdsourced prediction protocol raised $5.5 million by selling REP tokens long before the term initial coin offering (ICO) had taken hold. Now, after the release of a new version of its white paper, the system that would allow global users to bet on the outcomes of real-world events is getting close to a test launch.
But while Augur will allow people to bet on all sorts of events (from which team will win a specific sports game to whether the Dow Jones will break a certain price), the founders say users will have only one market to make when it goes live.
The Future Foundation's operations lead, Tom Kysar, told CoinDesk:
"Essentially, we are going to launch Augur with one market, and that market is: 'Will Augur be hacked?' or 'Will there be a critical vulnerability discovered in Augur' by a certain date?'"
If that seems risky, it is. But according to Kysar, it will be well worth it in the end.
In parallel with the bet, the Augur team will run a bug bounty, seeding the market with bets that the system won't be hacked. In this way, a confident hacker could then take the other side of those bets, and go to work trying to find flaws in the protocol to collect a big payday.
"From what we heard from our auditors, we'll probably be the largest and most complex application to be attempted to be deployed on ethereum," he said. "I think it's very naive to think we could launch 6,500 lines of Solidity code being bug-free."
In an effort to give outsiders plenty of time to find potential bugs, the team will be running the controlled launch for something like three months.
Augur is going through its second round of smart contract audits right now, and once complete, a live launch could be just months away, the team said.
Security model
As for what will be made available at the time, the platform is expected to finally permit real people to serve as "reporters" in the markets.
New markets need to designate a trusted reporter to determine how a bet resolves. Odds are, many of these will probably be bots of one kind or another, maintained by trusted developers (not unlike Polyswarm's approach to threat assessment).
Still, as outlined in the white paper, the system has two levels of dispute resolution in case participants disagree with an outcome.
At the most basic level, all Augur users are enlisted in resolving a disputed market. If a market dispute rises to the highest level, Augur forks into new "universes" for each outcome, and that's when a crowdsourcing procedure kicks in to determine the correct outcome.
An attacker could try to force an incorrect outcome through an attack, but the Forecast Foundation's models suggest this shouldn't be profitable.
In any case, whenever users participate in deciding how a market resolves, they will need to stake REP tokens to do so. Any time they stake on the correct outcome, they stand to earn a return.
"The system does also attempt to shift the value of REP upward, or downward, when needed by adjusting the fees that are given to reporters," Alex Chapman, Augur's lead contract engineer, explained. "While the cap of rep is below our target level, the fees will go up every week and vice versa."
Yet, as the team has been working on the project, they've realized there are limits to how far a project should go on distributing all work. Early on, the team wanted to have every market decide by participant votes. While that's still the backup plan for markets with disagreements, the team has come around to the idea that rewarding centralized decision making turns out to be more efficient.
Kysar said:
"Distributed reporting is really a worst-case scenario."
