    Official web3.js library needs better maintenance

    Posted: 27 Nov 2018 07:23 AM PST

    If you review the repo: https://github.com/ethereum/web3.js

    You'll see 350 issues, 50 of which are acknowledged as bugs, and a release cycle of up to 3 months. A 3 month wait for possible fixes for the primary API used by the vast majority of Ethereum developers is in my opinion unacceptable. Especially when such bugs include breaking changes.

    @EF - please hire more people to maintain this library.

    How can I best be ready for staking?

    Posted: 27 Nov 2018 08:18 AM PST

    I think the obvious part is getting 32(?) ETH, and I'm assuming I need to have them out of an exchange or coinbase, and the do I need to have a computer/wallet running all the time? Can I set up a RaspberryPi to do this? Sorry if these are dumb questions, but I'd love it if someone could point me on the right direction to learn more. Thanks!

    How does Quorum, JP Morgan's spinoff of Ethereum work?

    Posted: 27 Nov 2018 03:09 PM PST

    Is the ledger on Ethereum itself or a permissioned implementation with just EVM inside? I'm curious to see how the network functions as well without having a cryptocurrency and how JP Morgan makes money off of this.

    Newspapers and magazines missing the obvious Ether paywall

    Posted: 27 Nov 2018 04:44 PM PST

    Anyone noticed being asked to pay to access online content. All these media companies missing the obvious UX benefit of having automatic payment via Metamask without any hesitation. Too bad for them.

    Ladies, If He

    Posted: 27 Nov 2018 07:34 PM PST

    Ladies, if he:

    • texts you back within 14 seconds
    • promises you a better future
    • still needs work but is there for you when you need it
    • is only 3.5 years old
    • is accessible to people across the globe without permission, including those traditionally excluded from international financial development

    He's not your man. He's the Ethereum Blockchain.

    Has anyone tried to do the math on the (nearly finished) WeTrust ETH charity matching event? These numbers are crazy! 45:1 matching of small (.1 ETH) donations right now.

    Posted: 26 Nov 2018 09:16 PM PST

    Background: WeTrust's "Spring" platform is currently experimenting with one of the new "Liberal Radicalism" fundraising equations for charitable gift matching (this mechanism was designed by Glen Weyl, Zoe Hitzig, and Vitalik Buterin to make funding of public goods more effective). See here.

    Although the website mentions the use of some LR mechanism, it does not give the actual equation or a calculator showing how this works. Instead, it only shows the amount currently being matched per charity, and thus radically undersells how big of a match you can get for small donations via this campaign. After some digging one of the participating charities explained that this equation is the one being used. I then plugged in data from the website to [estimate]( the missing "match constant" α they have plugged in there. I put it back into the equation being used to evaluate how much matching would result from the minimum donation size (.1 ETH, about 10 USD at current prices) if donated to the current most popular charity.

    My mind was blown by the conclusion that small donations receive a whopping 45:1 matching ratio of almost 4.5 ETH at the present time, or a 470 USD match for your 10.50 USD donation. I can't believe they aren't advertising this more clearly! And this is genuinely by design, because the whole point of the equation is that it cares more about the total number of donors than just the total amount donated, so small donors are meant to pack a big punch. The way you can think of it is, for this particular charity there have been a few large donors, but they aren't really going to be matched very much unless a larger number of people donate. Small donations increase the number of people who have donated, and thus increase the matching ratio across the entire amount. Or just go check out that equation if you really want to understand (just realise that the equation is for the total, counting the actual donation, so you need to subtract that out if you are just trying to calculate the match).

    Anyways just though that people would be interested in this since I hadn't seen these details anywhere. It is really cool to see what these mechanisms look like in practice. I definitely felt that my small donation packed a way bigger punch this way, and hopefully you will too. But next time they totally need to make a little calculator on the site so that you can see all of this without having to reverse engineer their whole matching scheme.

    ​

    TL;DR: The matching algorithm here is intentionally designed to weight # of donors as more important than total amount donated, so small donations pack a big punch in this campaign. Go check it out!

    Edit: Oh, and they are handing out these ERC-721 "Nifty Shiba" tokens to anyone who donates. https://spring.wetrust.io/nft-about

    Ethereum libraries

    Posted: 27 Nov 2018 06:43 AM PST

    Is there an ethereum library? I am looking for a set of all available P2P books / pdfs. I imagine there is an ethereum database with swarm integration for books.

    An attempt to limit losses of compromised private keys

    Posted: 27 Nov 2018 12:50 PM PST

    Hi all!

    I wanted to get started with building smart contracts, so I've built a first version of a contract to store funds in a way that limits losses if one's private key is compromised.

    It simply has a withdrawal limit and a fallback address (which could be a cold storage, multisig wallet, or something else). Basically, if someone gets hold of your keys, the losses are limited and you can save the remaining funds by having them diverted to your fallback address.

    I am not aware of anything too similar but I suppose there is? Anyways, my first contract is now deployed on Ropsten. Feel free to try it out and send some feedback my way! :)

    More info here: https://github.com/larsholtsebonde/CryptoVault

    Cheers!

    Edit: Added greeting and ''' :)
