What are the possible solutions to the race conditions, created by ICOs so popular that they paralyze the Ethereum network?
Over the past few months, the cryptocurrency market has displayed a huge surge of interest in digital token sales, also known as Initial Coin Offerings (ICOs) or crowdsales. However, the best way to run an ICO - one which is good for both the project’s owners and its investors - remains to be found.
Many approaches to conducting a campaign have been tried out, but so far most of the crowdsales have been causing significant problems for everyone involved, as well as for non-participating network members.
In order to better understand where the problems with ICOs come from, we should take a look at the goals people usually have in mind when choosing to start a campaign.
To put it briefly, most projects who decide to run a crowdsale want to do three things:
raise money for the development of the project
make sure that their tokens are distributed across as many users as possible. This helps ensure that the token value will be more fairly determined and decentralize access to and/or ownership of the project. A larger number of token holders also means more potential users, especially if the tokens are directly usable in the project’s ecosystem.
make the experience as painless as possible for their supporters to encourage more people to invest, again ensuring distribution amongst more users.
As it turns out, there are several problems when it comes to running a user-friendly crowdsale campaign that accomplishes all three of the above goals. To break it down, let’s look at some of the main factors at play.
When running an ICO, project creators usually decide to cap the number of coins they will sell during their campaign for a number of reasons. In particular, they want to be able to set an initial price for the tokens and not to accidentally collect way more money than they actually need for the development.
Additionally, a large chunk of recent crowdsales have only accepted Ether as crowdsale contributions, which just means lots of transactions take place solely on Ethereum’s network.
Problems come up with how the Ethereum network functions under certain conditions, known as ‘race conditions.’ These conditions have unfortunately been created by many ICO campaigns (recent examples include Status and Bancor), due to flawed design of the token sale models.
Put simply; race conditions are a combination of high demand, limited supply (amount of tokens for sale is capped), and/or limited time (the duration of the campaign is also capped). What happens under these conditions is that a lot of people want to make sure they buy some tokens out of fear of missing out.
As such, they all attempt to make transactions at the same time, usually within seconds or minutes since the campaign’s start.
Since, as mentioned above, many of these transactions are concentrated on the Ethereum network, popular crowdsales can cause severe network overloads, which in turn causes delays and cancellations not only for campaign-related transactions but for all transactions on the network.
Ethereum’s Blockchain requires you to pay a small fee called ‘gas’ every time you ‘do something’ on the network - whether it’s sending money or running a smart contract. The gas - think of it as fuel that makes the transaction happen - is paid to the miner that actually does the work to process the transaction.
This system was designed so that work that was deemed more important would also be more valuable and end up prioritized by the miners. So, gas ends up working as something like a bidding system - when you initiate a transaction you can set the price of gas you’re willing to pay, knowing that miners are willing to do more work or do it faster if they’re offered more gas as a reward.
It’s important to note that there is nothing inherently flawed about Ethereum’s fee system and in general, it manages to do what it was designed to do.
However, in the case of running an ICO campaign, things get a little more complicated. Given the special race conditions described above, people who contribute to a crowdsale are incentivized to set exorbitantly high gas prices to make sure that their particular transaction will get processed faster, before the ICO is complete - either by reaching its funding or timing cap.
Obviously in this scenario, wealthier ICO participants have an unfair advantage, because they can afford to throw away thousands of dollars in gas.
One way ICO makers address this problem of unfair distribution is by choosing to set a limit on the amount of gas each contributor is allowed to set per contribution to the ICO. In theory, this would prevent those who could afford to pay huge gas prices from beating everyone else to it.
Status chose to do exactly that during their ICO, in addition to taking other precautions to prevent unfair distribution. However, despite their well-intentioned efforts, race conditions were still in place and Ethereum’s network became severely overloaded during their campaign.
Status ended up returning 111,161 attempted transactions - a total of 347,154 ETH - due to problems with network overloading. As you might imagine, everyone who wanted and tried to participate, but whose transactions were returned were upset and disappointed.
This overload also caused big problems for those who weren’t even involved in the ICO, but just wanted to use the Ethereum network. Canceled and delayed transactions affected many cryptocurrency services, especially the exchanges - some exchanges were forced to suspend all ETH withdrawals during the period of overload.
Some organizations are looking for better ways of conducting ICO campaigns. ICObazaar is a self-described ‘participation platform’ for crowdsales that claims to have a solution to the problem of race conditions.
Cointelegraph has reached out to its representatives to learn about the platform’s experiences and the measures it takes to ensure the fair and painless distribution of tokens during ICOs.
CT: First of all, what is your platform about? What's its mission?
ICObazaar: Our mission is pretty simple - we want to make it easier for people to participate in ICOs. That’s why we call it a ‘participation platform.’ Anyone who has contributed to a crypto crowdsale knows that the process is more often than not fairly complex and frustrating. We provide people with a more intuitive and user-friendly option.
Our platform is a place where you can explore and contribute to different crowdsales at various stages of fundraising. Rather than searching around for info on new ICOs, you can just come to our site and see all the official info in one place, and then contribute to them right there. And of course it’s way easier to always use the same simple payment interface, rather than figure out a different one for each individual ICO.
CT: What solutions do you offer to the race conditions?
IB: Our solution is basically to avoid these conditions entirely. One way we do that is by providing expanded access to campaigns at various stages of fundraising. By expanded access, we mean that on our platform, in addition to ongoing ICO campaigns, you can contribute to select campaigns both before they publicly open and after they’re publicly complete.
That means you can calmly and conveniently secure your tokens while avoiding all of the hassle caused by race conditions and commonly associated with ICOs, like uncertainty, waiting, missing out on a campaign, etc. On our platform, the whole process is much easier and smoother.
CT: Can you give us some highlights of successful crowdsales featured on your platform?
IB: Sure - I think we’d define most successful as those crowdsales that turned out to be the most chaotic and not user-friendly during their public campaigns, but that our users had a totally different experience of, such as Bancor, Civic, Status and Patientory. Lots of people who tried to participate in those public campaigns ended up not being able to for a variety of reasons, namely caused by race conditions. But after those public campaigns were over, and before the projects deployed their tokens, our users were able to easily get tokens on our platform from those same ICOs, completely avoiding the chaos and problems present during the public campaigns.
CT: Let’s talk about the market in general. There have been stories of people who can barely operate a computer buying into ICOs just because of all the hype. Do you think we are in a bubble?
Clearly there is a lot of hype, and not every new project deserves or will get funding. But to put it bluntly, no this is not a bubble. The main reason being that the technology behind digital tokens makes them function differently from traditional assets, and so we can’t talk about their ‘value’ in the same way. In many cases, tokens have specific uses and value within the project that created them, such as Ether in Ethereum. So even if there’s a big surge of excitement and interest in the ICO phenomenon happening right now that feels hypey and will likely cool off a bit, the technology behind this industry is solid and it’s not going anywhere. The same should be said for the model itself - after all, the ICO is a new funding model that is decentralizing, incentivizing, and democratizing crowdfunding and funding in general. Going forward we hope to see the model continue to improve and stabilize.
CT: And a final prediction from you: how much money do you think the largest ICO of 2017 will secure?
Well, this year we’ve already seen a single project raise $232 mln (Tezos) and there’s no reason to say a really good project couldn’t raise much more than that. This is an exciting time in an emerging market and records are continuously being set and broken. The main thing is that these super successful projects are attracting the attention of more and more people outside of crypto, which is great. More people are learning about the possibilities that this new funding model offers, and services are emerging (like ours) that make it easier for people to support new projects or to start their own ICO and get their ideas off the ground.
