    3 Years Since Ethereum Launched!

    Posted: 28 Jul 2018 07:41 PM PDT

    This time 3 years ago Ethereum launched. It was trading between ICO price of 30c & 50c if you could get your hands on some. I was busy reading about how it was a 'shitcoin' on the r/Bitcoin subreddit and waited until 2016 to buy.

    Addressing Nano's weaknesses (bandwidth usage and disk IO). Nano voting traffic to be reduced by 99.9% by implementing vote by hash, lazy bootstrapping, and reduced vote rebroadcasting (x-post r/CryptoTechnology)

    Posted: 28 Jul 2018 08:08 AM PDT

    Voting traffic currently dominates the Nano network (vs actual transactions), because of the size of the votes, the number of times nodes vote, and the number of nodes those votes get rebroadcasted to. This reduces node throughput, makes it harder for low-end nodes to survive increases in transaction traffic, and reduces overall network scalability.

    The Nano devs are now implementing a number of interesting solutions that should drastically reduce the voting bandwidth (99.9%) and required disk IO of the Nano protocol, which are the network's two biggest bottlenecks.

    Vote by hash - Initial reduction from 40 kilobytes of voting traffic per block to 600 bytes per block (98.5% reduction) by not including the full block in each vote and only using the block's hash.

    Lazy bootstrapping - Right now a block may get voted on thousands of times during it's lifetime by nodes that don't actually care about the block or chain it's on — AND they'll vote on other blocks which reference that block indirectly, leading to thousands of unnecessary votes. Passively listening for blocks and only pulling down chains that a node cares about solves this, and drastically reduces overall voting traffic.

    Vote stapling - Votes by reps are signed and distributed with blocks, so that when a node gets a new block that has already been voted on, it will no longer request voting confirmation once more from the representatives. The votes will be sent in a bundle with minimal vote traffic.

    Vote rebroadcasting - Since v13, the redundancy of nodes voting 4 times on each block (which in turn are rebroadcast) is no longer needed. This is because nodes now automatically seek them out if they're missing. This leads to lower votes, fewer relays, and will decrease network traffic by 75%.

    TL;DR:

    Nano is about to get a lot more scalable (99.9% less voting traffic). Stress tests will follow.

    Correction from one of the devs on vote stapling:

    While vote stapling can definitely be used for this (and presumably will be in the future), that's not what it'll be first used for. With vote stapling, when a node publishes a block, it will first communicate directly with representatives to make an aggregate signature. Then, the node will publish the block along with the aggregate signature in the same message. The aggregate signature is the same size as a normal signature, because it uses a multisignature protocol called MuSig: https://blockstream.com/2018/01/23/musig-key-aggregation-schnorr-signatures.html

    This means that we can package up the entire voting process into the size of one vote.

    I thought us cryptocurrency investors take too many risky bets

    Posted: 29 Jul 2018 03:10 AM PDT

    ...until I stumbled upon r/wallstreetbets. I must say it's a highly entertaining sub, but goddamn, every day I see a 100-500k all-in put or call option (very risky trade that can make you lose a lot of your money but sometimes 10-25x your money overnight).

    I admire some of their balls but how can people actually do this while sleeping peacefully at night?

    After the metamask - chrome store debacle. What web wallet are you using now?

    Posted: 29 Jul 2018 03:17 AM PDT

    Im currently using Nifty by POA Network

    *They are part of the ethereum alliance

    *They aren't going to be a big target like metamask

    *Nifty creates a private key-pair via a seed and is accessible through the web browser. You will maintain complete control of your private keys, which can be used to access funds anywhere. This is an advantage over other software wallets that do not give you access to your keys.

    *Nifty allows you to keep ERC20 tokens all in the same location, as well as allowing you to view your account on the ETH blockchain. With Nifty you can send/recieve without having to download any software to your computer.

    *Nifty allows your browser to directly connect to dAPPS, such as games and decentralized exchanges like Etherdelta

    *Nifty works directly with the POA Network and any blockchain hosted on it. This gives you easy access to your gaming funds for all the new games coming to POA.

    *I use Nifty wallet to easily play DopeRaiders

    Link to the chrome extension: https://chrome.google.com/webstore/detail/nifty-wallet/jbdaocneiiinmjbjlgalhcelgbejmnid

    What are you guys using?

    Statistics for POS coins

    Posted: 29 Jul 2018 02:13 AM PDT

    Hi all,

    For masternodes we have sites like https://masternodes.online which tell us how many Masternodes exist (from which we can work out how many coins are "locked" in rather than in circulation)

    Is there a similar service for Proof of stake coins?
    Where can I get such information?

    Thanks!
