    Proof of Volatility?

    Posted: 13 Mar 2018 06:11 PM PDT

    So, I'm not entirely sure what to make of this: https://ethphoenix.io/docs/PhoenixCoin_Whitepaper.pdf

    For anyone too lazy to read it, let me give a one sentence back story: Self perpetuating Dapp pyramid scheme proposed by mathematician -> Live implementation fails due to bad devs -> Better devs reimplement and relaunch it -> someone creates a betting pool pseudo-Futures contract based on the underlying pyramid contract.

    So anyway, enough of that. One of the devs has proposed a new Proof system - basically, by using the participation in the underlying pool (ie the pyramid smart contract) as something like a Proof of Stake, there's now a NEW contract that uses the volatility of the pool to issue a new ERC223 token (ostensibly so it can eventually be used in other Dapps, games and whatnot I imagine). The volatility itself (which since it generates fees) is used as the "value" underlying the new token.

    So: Forget all the pyramid stuff, it's just the usual Ethereum Dapp shenanigans. I'm more interested in the technical concepts behind this. I'm still pretty new to Dapp writing (still working on my first project - never enough hours in the day!) so I would like a wider opinion on this.

    From a technical perspective - is this PoV concept viable, obviously not for separate blockchains but for the issuance of new tokens by smart contracts? It reminds me a little of MakerDAO and the use of CDP's to control the issuance of DAI. What's the possible exploits of using this PoV?

    One criticism I have would be that it's a bit arbitrary - why not just issue a token directly, without ANY underlying contract? I guess the argument would be that the value given to the token is derived from the Ether locked up in the pool - ie it's similar to how something like Neo operates via issuing Gas to stakers. But since this is ALREADY operating on top of a platform, that itself operates on a Proof system (ie Ethereum itself), is this necessary or beneficial to the wider ecosystem?

    I'm also curious to see the source code - it's not been published yet unfortunately. See, I can think of quite a few other applications for this, like using some underlying contract to issue an in-game currency for example.

    So, what does everyone think (leaving aside opinions on Ethereum pyramid schemes)? Clever idea or terrible?

    Edit: A word.

    Ethereum Bracket Challenge 2018

    Posted: 13 Mar 2018 09:25 AM PDT

    The Ethereum Bracket Challenge is back and better than ever (or at least the same)! If you didn't see last year's, this is where the action happened: https://www.reddit.com/r/ethereum/comments/5z88f6/ethereum_march_madness_bracket_challenge/.

    Unfortunately, I didn't give myself enough time to prepare this year, so I am only deploying the dApp to the Ropsten testnet. On the other hand, I'm raising the stakes from 0.25 real ETH to 1.0 whole testnet ETH and also doubling the fun by deploying both men and women's bracket challenges!

    To play, you will need an Ethereum client (MetaMask recommended) and some Ropsten testnet ether. If you don't know how to get those or want a primer on using dApps, check out my Ethereum Development Guide: https://github.com/jimpo/ethereum-development-guide.

    Rules

    The contest has five phases:

    Setup: Before the contract is deployed, 4 human oracles (listed below) are preselected to accurately report the results of the NCAA tournament to the contract after the tournament ends. When the contract is deployed, the entry fee, timeline, and oracles are specified by the creator.

    Submission: During the submission phase, entrants pay the entry fee to submit a cryptographic commitment to their bracket picks without publicly revealing their actual bracket picks. Each address may only make one submission. The users will be given a submission key by the UI encoding their bracket picks that they must keep in order to later reveal their bracket and be eligible to win. The submission phase ends at 12:00PM ET on Thursday, March 15.

    Tournament: Once the tournament starts, no further submissions are allowed. Games outcomes are not reported until the entire tournament is over to simplify the process for the oracles. When the tournament ends, the oracles each submit the outcome and if 3 of them agree, the next phase begins. If the oracles cannot reach consensus in the aftermath of the tournament, entry fees will be returned to the entrants.

    Scoring: During the 3 day scoring period, entrants may reveal their bracket picks and score their brackets. The highest scoring bracket revealed is recorded. After the scoring period ends, all entrants with a highest scoring bracket split the pot and may withdraw their winnings. There are no tiebreakers.

    Contest over: When the scoring period ends, all entrants with a highest scoring bracket split the pot and may withdraw their winnings.

    Disclaimer: There is an inherent risk to using decentralized applications, so do not enter funds that you are not willing to lose. Except that this is all testnet ETH, so YOLO.

    Oracles

    I'd like to present your lovely oracles this year along with IPFS links to PGP-signed statements by each of them. Thank you to all of them for agreeing to help out.

    How are Ethereum based companies' co-founders sorting out (percentage of) ownership?

    Posted: 13 Mar 2018 08:01 PM PDT

    I'm working on a new project with two other people and looking to determine who gets what in the company. There are three of us (so far) and I'm the team lead / CEO. There is a tech lead in the team. And there is also someone who I believe will be a great fit for marketing / business development / operation.

    Curious to know how other Ethereum project teams have approached this when establishing their organizations. How did they distribute shares / percentage of ownership?

    Note: we are not doing an ICO.
