The terms of a much-hyped bet have finally been settled, and, at current prices, more than $500,000 in crypto is on the line.

“It’s a maximum pain kind of bet,” Jimmy Song said during a session of CoinDesk Live at Consensus 2019. “Skin in the game.”

The new details stem from an onstage agreement from Consensus 2018, where Lubin told Song that he would bet “any amount of bitcoin” that ethereum’s decentralized apps would have a non-trivial number of users in five years.

Song had accused Lubin of “weaseling” out of the bet in recent weeks, including calling Lubin out on Twitter.

But the meeting of the two crypto thought leaders on Tuesday did not disappoint, especially in terms of how much crypto was wagered.

Deal terms

If ethereum is doing great four years from now, Song will pay Lubin (or his beneficiary) 810.8 ETH. If the dapp economy is sputtering at that point, Lubin will send Song 69.74 BTC.

For Lubin to win, Ethereum needs to have five unique dapps achieving 10,000 or more daily active users and 100,000 monthly active users for any six calendar months in any 12-calendar-month period up to and including May 23, 2023.

To be clear, this is not a small bet for either side, and both acknowledge that whichever side wins, it will hurt badly. It’s also possible the loser will be giving up considerably more money in 2023 than they would today.

When the bet was first made, on May 14, 2018, BTC was trading at $8,577. So, Lubin had effectively bet $598,190 based on prices at the time. That’s $564,307 at today’s prices.

The difference in ETH was much more stark, however. At the time of the bet last year, ETH was trading at $722.86. So, Song effectively bet $586,095 at prices at the time – but only $168,030 at today’s prices.

If he wins, Song was very clear that the BTC will go straight to him. “I want it to hurt for you,” Song told Lubin. “I don’t want you to feel like you are donating to charity.”

“I’m fine with that,” Lubin replied.

The terms have slowly been hammered out over the last year since the bet was first spoken into existence. The two sides have been working on a shared document that they’ve committed to share with CoinDesk once the final piece is in place: settling on a public arbiter.

“Jimmy’s thesis was that there would be no significant applications on blockchain, and the only thing relevant in blockchain was bitcoin,” Lubin said on CoinDesk Live. “My thesis is bitcoin is awesome, and there’s a narrow set of use cases built on bitcoin and that’s wonderful. We love that, but decentralized applications are also really useful.”

There are some definitions of daily active users in the document. The point, Song explained, was for the dapp in question to achieve something like the numbers an Android mobile app would need to be deemed an early success.

Critically, Song argued that the transactions only count if they are on chain. It doesn’t matter who pays for the gas to put them on chain, he agreed (the startup itself could front that), but it needs to hit the base layer.

The sticking point had been what it meant to spend money, but once Song agreed that it didn’t have to be paid by the user – as long as it hit the chain – terms were done.

Lubin proposed a hug and Song accepted.

Web3 or bust

At its core, the bet hinges on whether the decentralized web will come to fruition – and whether ethereum will deliver it.

Song argued that centralized technology will always be faster and easier to develop on, and that’s why he doesn’t believe the decentralized web has a future.

“The only reason dapps exist is to raise money from gullible people or from greedy FOMO people, and that’s essentially what the ethereum platform has done,” Song said.

It’s possible that the world could change in a way that doesn’t fit the terms of the bet. For example, Felix Salmon and Ben Horowitz made a bet five years ago that bitcoin would be widely used in payments. Five years later, Horowitz lost that bet, and yet at the same time he’s still won by investing successfully in crypto.

To that point, Lubin noted:

“It’s possible that there are many many successful applications on ethereum that are sufficiently decenteralized and they don’t hit exactly those two criteria. So it’s possible I will lose and the ecosystem will be strong.”

Correction (May 15, 18:57 UTC): According to the terms of the bet, ethereum needs to have five unique dapps achieving 10,000 or more daily active users, not 15, as was previously reported.
