Today, OpenSea is announcing a new type of tradable digital assets on the marketplace: ERC-1155 items. In short, these are like ERC-721 items, but they have different behavior and more flexibility, which we’ll explain below. It’s a new Ethereum token standard and a new type of dapp on OpenSea!

ERC-1155 items have been tradable on OpenSea for a while now (there are over 200,000 that you can find already), but today they get the full attention that they deserve. Let’s start with what’s new in 1155. Then we’ll explain how you can get started trading, which games are already supported (17 so far!), and how developers can make 1155-compliant dapps!

What is ERC-1155 and What’s New

The ERC-1155 token standard provides a way to make one smart contract govern almost an unlimited number of tokens — technically, 2²⁵⁶ token types with up to 2²⁵⁶ copies of each. Additionally, each token is semi-fungible. Unlike ERC-721 non-fungible tokens (NFTs), which can only be owned by one address each, semi-fungible means:

1. Each token type can be owned by multiple addresses
2. One address can own multiple copies of each token

This expands the design space for building game economies and provides efficiency benefits as well. ERC-1155 is a result of the combined efforts of multiple companies working together to achieve these two goals, including Enjin, Horizon Games, and The Sandbox.

What’s needed now is a marketplace for the (at the time of writing) 208,319 new semi-fungible assets on Ethereum! And that’s what’s here today:

Our decentralized game economy calls for the proper adoption enablers. Trusted marketplaces are a must-have. Our friends @opensea are now supporting #erc1155 tokens and we couldn't be happier. Go to https://t.co/QKijcajWKj to trade our tokens. Watch for a Special Charm too 👀

How to Trade ERC-1155 Tokens on OpenSea

Check out your OpenSea account page to see which items you already own, or visit the supported collections on OpenSea (listed below) to buy one.

To sell an ERC-1155 item, it’s as simple as clicking Sell, and then specifying the total price and quantity you want to sell. If you specify an end date, the price will decline to the amount you want until the end date is reached, and then your listing will be automatically cancelled (expired) for free.

You only have to pay gas the first time do you sell an item (which may include approving the token for trading). If you want to sell for Enjin ENJ, Sandbox SAND, or another payment token, click the dropdown below and set your price:

Placing Offers

As with other tokens on OpenSea, you can place offers on 1155 items by clicking “Make an Offer” on the item’s page. Offers are non-binding, but because an item can have multiple owners now and any owner can accept it for you, many people will consider your offer at once!

ERC-1155 Games on OpenSea

Even before this official launch announcement, there are already 17 games on OpenSea using mainnet ERC-1155 contracts, and many are already ranked in the top fifteen dapps by volume. Here’s a full list, with many more to come! Special thanks to all of them for working with us to make a great marketplace experience.

What’s the best way to sell crypto collectibles? Their value is based on market demand, which is hard to measure, and there’s no “Kelley Blue Book” for pricing them. So you have to put them on auction, and until now, only the seller was setting the price curve.

Now, on OpenSea, you can let buyers compete to find the best price for your item or bundle of items!

Two main types of auctions

There are two main types of auctions: “English” and “Dutch.” The paradigmatic type of auction that you see for existing crypto collectibles like CryptoKitties, Etheremon, and MyCryptoHeroes has been the Dutch Auction. In this form, a seller lists an item for immediate sale, but sets the price to change over time. Buyers make purchases hoping they see these listings at the right time.

But the type of auction that most people think about is the English Auction, where you list your item for a minimum price and accept the highest bid after a set time period. This is the type of auction made popular by eBay* that you see for physical items there, and now it’s available on OpenSea. Here’s what the two price graphs look like, side-by-side:

Why English Auctions can be better

The primary benefit of an English Auction is that the seller doesn’t have to know the market value of their item when they price it; instead, they can low-ball a guess, and the market will drive the price up to the seller’s benefit.

What about buyers? Buyers love English Auctions, which feel like games with winners and players. Most importantly, as long as the starting price is low, buyers don’t have to know the market value. Dutch Auctions essentially require buyers to know the true value because buyers purchase hoping that they saw the item at the right time, and therefore the right price. In reality, determining price involves a conversation between more than just one buyer and one seller, and English Auctions enable that.

For example, let’s say a CryptoKitty with a market value of 0.5 ETH is currently on sale for 1 ETH and declining to 0 ETH over 2 months. Along comes a buyer who doesn’t know how much it’s worth. The buyer might purchase the item out of fear that someone else will snag it later, even though it’s currently too high of a price. In an English Auction, the seller will list the CryptoKitty for a low-ball guess (e.g. 0.4 ETH), and if demand for the kitty truly is high, then its price will naturally rise to 0.5 ETH as buyers outbid one another. It’s a multi-party conversation about value where every party has skin in the game, which has until now hasn’t had a first-class experience on OpenSea.

Gas-free for both buyers and sellers

Why not just ask buyers to make offers on your items, like OpenSea has allowed for months? Because an English Auction guarantees that the highest bidder will win the item when the auction expires, regardless of whether the seller is awake or not. And we’ve added a nice feature that makes this guarantee possible: OpenSea will auto-match the highest bid with the auction, so neither sellers nor buyers have to pay gas!

How does this work? It’s a three-step process. First, sellers create auctions by creating and signing an off-chain sell order, which OpenSea stores off-chain with the OpenSea API. This involves no gas as long as the seller has already approved those assets for trading.

Second, buyers create buy orders in the same way, which also only requires signatures. To bid on an item for sale in an ERC-2O token like DAI (a stablecoin pegged to $1 USD), they just need to approve the token and have enough of it. If the item is on sale for ETH, buyers need to wrap ETH into W-ETH, which can be done when bidding or any time using the W-ETH Station on OpenSea. This allows the trade to happen when the buyer is asleep, without the need to escrow ETH into some non-standard contract, and the seller will receive W-ETH instantly that they can unwrap into ETH at their discretion.

Finally, when the sell order expires, OpenSea’s servers look for the highest buy order that’s at least the minimum amount specified by the seller, and pays the gas to match the two together. For the first time ever, no user (not even the order taker) needs to pay gas to fulfill the final transaction!

Bundle Offers

With this new auction ability comes another highly requested feature on OpenSea: making offers on bundles. Now buyers will be able to suggest prices they’re willing to pay for your bundles on Dutch Auctions and fixed-price listings.

As an added bonus, if your bundle expires or you cancel it without finding a buyer, it’ll still be available for buyers to find and make offers! And a new “Re-list this Bundle” button makes it easy for you to quickly bring it back to auction and renegotiate a price. We hope this will make it easier for everyone to trade complex bundles and talk $ to sellers without spamming them.

Give it a try!

We’re very excited about English Auctions, so give them a try and put an asset on sale by visiting your account: https://opensea.io/account. OpenSea doesn’t escrow your items, so you never lose hold of them!

If you’re a developer, we’ve also added support to the OpenSea SDK for programmatically creating English Auctions, querying for them, and bidding on them. You can even add an address as a referral address and claim referral bounties, both through the SDK and by creating referral links.

For more information, or if you have any feedback, contact us on Discord or contact us at support.opensea.io!

* Despite the widespread belief that all eBay listings are English auctions, most eBay listings are fixed-price now.

We see thousands of student polls every week on Whatsgoodly covering topics from politics to dating to college life. So one day we asked ourselves an obvious political question: what happens if we sort our personality polls by how much Trump supporters differ from Clinton supporters?

Before the 2016 presidential election, we created the Winsights Library to make this task as easy as possible. We reorganized our 800,000 polls, tracking how Trump supporters and Clinton supporters differ on everything from pineapple pizza and Jurassic Park to dating and sex. Today, we checked the results. Here are the three most significant trends we found:

#3: Trump Supporters Value Making Money Over Feeling Important

We analyzed a poll asking millennials if they care more about “being important” or “making money.” Out of 1,089 respondents, 55% voted for money and 45% voted for importance. This contrasts with common speculation that millennials work more for purpose than for money, but it may also be a false dichotomy: according to Fidelity’s online sample of 1,500, work/life balance and company culture are turning millennials’ heads more than paychecks.

Either way, an interesting thing happens when you break down the results by presidential candidate preference:

Trump supporters are almost 20% more likely to value money over feeling important. This begs a followup question: what does “being important” mean to Trump supporters versus Clinton supporters? Is it fame for Trump supporters but fulfillment or power to Clinton supporters? Or are Trump supporters simply aligned with Trump’s emphasis[1] on high net worth as an end-goal?

#2: Trump Supporters Consider Themselves More “Instinctive” Than “Thoughtful”

Anybody surprised? Didn’t think so. Trump himself is both praised and criticized for being impulsive. His supporters mirror him, being 17% more likely than Clinton supporters to follow their gut:

This poll was conducted 3 weeks after the election, and it shows Clinton’s reliance on calculated reflection in her supporters. (Coincidentally, 60% of all respondents claim to be more thoughtful, which is exactly the same as the share of the millennial vote that Clinton received.)

#1: Male Trump Voters Consider Themselves “Alpha Males,” while Male Clinton Voters Don’t

We noticed this poll back in March: Do you consider yourself an alpha male? An alpha male assumes a dominant role in social or professional situations, and Trump’s team consistently touted his alpha personality as a key strength. Vice President Mike Pence used to routinely explain that Americans should back Trump because we need “broad-shouldered leadership,” which some interpreted as a sexist dig at Hillary Clinton.

But why, exactly, do Trump’s supporters crave an alpha-male personality in the white house? We asked male American millennials if they considered themselves to be “alpha,” and found a possible explanation in the results. Male Trump supporters are a whopping 21% more likely to consider themselves alpha males than their pro-Clinton equivalents, marking the most significant personality difference to date in our two-year-old database of 150 million responses [2]:

This data could explain why two-thirds of Trump supporters believe that society has become “too soft and feminine,” while 78% of Clinton supporters don’t. Alpha males may seek “broad-shouldered” leadership that reminds them of themselves.

Summary

If America is like a high school, then the 2016 election was a battle between classic stereotypes: instinctive, dollar-driven alpha males versus reflective individuals. It wasn’t merely a national disagreement on how society ought to be — it was a conflict of personality types. Future campaigns are going to need to appeal to both constituencies… or just double down on their own cliques.

Whatsgoodly is the largest social polling app for millennials. Learn more here.

Methodology:

Results for these Whatsgoodly polls were collected between November 30, 2016 and April 20, 2017 from 2,685 U.S. respondents aged 18–24. College-aged respondents verified their university through school email and location. Given the population of U.S. millennials, the margin of sampling error on all polls mentioned here is ±3 percentage points at the 95% confidence level.

Notes:

1. As Trump told Forbes, “I’m worth much more than you have me down [for]. I don’t look good, to be honest. I mean, I look better if I’m worth $10 billion than if I’m worth $4 billion.”
2. Interestingly, the equivalent poll asking women if they considered themselves “alpha females” didn’t show a significant difference in the results, indicating that this alpha personality clash is very specific to men.

Current millennial approval ratings, updated daily

To track and visualize Trump’s approval ratings over time, we built a public Trump Tracker, with timelines that measure millennial opinion on controversial issues since he started his campaign. Hundreds of Americans between the ages of 18 and 30 are voting every day. Check out the demographic breakdowns of his overall approval rating as it stands right now.

Each timeline includes an Analyze button for viewing demographic breakdowns on each poll, along with a table showing how different universities voted from around the country. Each survey has between 1,867 and 11,312 respondents at the time of writing, yielding a margin of error that’s among the best in the polling industry (< 2%, for a 95% confidence interval).

Why Time-Tracking Matters

A notable takeaway from these visualizations is how sensitive millennial opinions are to events covered by the media. Notice the dip in presidential approval pictured above, which occurred after Trump’s executive order on Jan 27 barring entry into the United States from seven predominantly Muslim countries. (This aligns with Gallup’s job approval poll.)

Even more pronounced, check out the crushing dip in Trump’s favorability after the first presidential debate on September 26th 2016, and then the incredible rebound after the second debate on October 9th:

This shows the importance of maintaining continuous surveys instead of doing one-offs over just a few days, like Fox News’ 5-day Quinnipiac Poll on the immigration ban. These are easily biased by rousing and concurrent events in the news. In Fox’s case, not only was the January 5th poll taken a whole month prior to the immigration ban’s enactment, but it also coincided with the Fort Lauderdale shooting that same weekend, which likely biased it towards the side promoting national security.

The future of polling is in continuously measuring what people think. Opinions aren’t timeless, so polls shouldn’t be either.

Exit polls match Whatsgoodly’s projection: millennials were split 60/40 between Hillary Clinton and Donald Trump

Trump’s victory embarrassed nearly every pre-election pollster. Even the British research company hired by Trump’s own campaign predicted his chances at less than 30% the day before the election.

Part of the upset was how many millennials (aged 18–29) voted for Trump when they were expected to vote in a landslide for Clinton. Compared to President Obama in 2008, she underperformed with millennials by 3 to 13 percent. SurveyMonkey even predicted that Clinton would sweep 88% of the electoral college if only millennials voted.

We at Whatsgoodly focus only on millennials. While 98% of our polls are created by users, we made election polls every few weeks up until election day. Our results were within negligible distance from exit polls conducted after the election (1). (Note that the exit polls surveyed 4,629 millennials; not as many as our 14,595, but still a very low margin of error, at 1.4%.)

It’s hard to know all the issues with the mainstream pollsters until the AAPOR completes its review in May 2017. Even then, there are too many variables to really isolate any of them. But aside from having a much larger sample, we postulate that our results were accurate for two reasons: content diversity and lower nonresponse bias. Let’s go through both of those now.

Dangers of the Echo Chamber

If you’re a liberal millennial, you probably saw this image shared all over your social media, claiming that millennials overwhelmingly voted for Hillary Clinton. It’s misleading. The data comes from the same SurveyMonkey pre-election survey mentioned earlier, and most shares were of a cut of the data dated October 25th. It doesn’t represent how millennials actually voted (the government doesn’t even release that data), and it isn’t from an exit poll asking voters to reveal their picks.

This is a great example of content homogeneity: a story that validates intense emotions will ricochet like a superball around newsfeeds that promote similar content. It’s a complex but engaging algorithm that powers most of the social media world today, including Facebook, Instagram, and Twitter.

Instead of feeding into these echo chambers, Whatsgoodly seeks to break them. Users connect to their school or community, and within those communities, they can anonymously poll each other and engage in open, honest dialogue without fear of backlash. Whatsgoodly is about understanding how your entire community feels; it’s about empowering the moderates to be heard over the fringes who yell the loudest.

Capturing More Perspectives

Pollsters are struggling to recruit panelists. Landline telephones — which are much quicker and cheaper to call than mobile phones — have been steadily disappearing over the last 20 years. Almost 50% of Americans only have mobile phones now. As a result, response rates on market research surveys have dropped from almost 40% in 1997 to just 9% today.

Millennials are the biggest generation ever, and they’re at the crux of this shift. But the survey industry has lingered in the landline world. Even the national exit poll used by all major media outlets this year was only able to survey early and absentee voters via the telephone!

When millennials in particular get excluded from polls, it causes nonresponse bias, the unfortunate situation in which people who aren’t being surveyed are systematically different from the people who are. Nonresponse bias may be the main reason for SurveyMonkey’s significant inaccuracy this year. Their Election Tracking poll is sent to a random sample of the people who’ve given SurveyMonkey an email address, thus excluding millennials who shun conventional messaging like email compared to in-app communication. If these millennials are systematically different citizens (and indeed they are), we have a problem.

This is where Whatsgoodly comes into play. Our userbase is almost 100% millennial, and response rates on most polls are 60–90%, depending on how relevant the poll is to the community. It’s the only truly mobile millennial panel and a fundamentally different way to collect public opinion. Most of our users don’t care about email, and polls at our high schools show that the upcoming wave of voters has almost completely abandoned it. We won’t know for sure until May, but our users in Rust Belt states may have had a critical role in our prediction’s accuracy. Many of our Trump-supporting users, for example, had reservations with revealing their opinions elsewhere:

The Largest Panel of Millennials in the Country

Our predictions come from our userbase as-is, so we’ll be transparent about what that looks like. Out of 38,602 U.S. millennials who saw our first pre-election poll (see map), 14,595 of them voted on it.

Our demographic makeup looks like this (2):

Full breakdowns by school and more than 400 demographic attributes are available for every poll on the Survey Dashboard. The language breakdown, for example, shows an interesting result: millennials who grew up speaking both English and Spanish were much more likely to prefer Clinton back in August, but other segments were much less decisive.

Given how much attention they get on the web, it’s hard to think of millennials as being systematically ignored… But this election was a gut-punch for the polling industry, and a fundamental restructuring is needed. Organic community insights could lead the way.

(1) Exit polls came from Edison Research for the National Election Pool, a consortium of ABC News, The Associated Press, CBSNews, CNN, Fox News and NBC News. They are based on questionnaires completed by 24,537 voters leaving 350 voting places throughout the United States on Election Day, including 4,398 telephone interviews with early and absentee voters. According to Fox News, which subscribes to Edison, 4,629 of them were between the ages of 18 and 29.

(2) Respondents with a reported age of 30 or above included for completeness, but none of them were included in the pre-election poll results.
