    Ethereum [Fun fact] If CryptoKitties were deployed on EOS, the devs would need to have $1.43B of EOS tokens just to be able to run the dApp

    [Fun fact] If CryptoKitties were deployed on EOS, the devs would need to have $1.43B of EOS tokens just to be able to run the dApp

    Posted: 16 Jun 2018 11:30 PM PDT

    In EOS, every dApp has a limit of resources it can spend, which is the share of EOS tokens the dev holds. At some point, CryptoKitties were consuming 15% of all the network's gas. So for such a dApp to be able to operate on EOS, the dev would need to have almost $1.5B of EOS tokens which are subject to 5% yearly inflation (block producers' reward). This is much more expensive than even NEO, which is $7000-$65000 for a contract and is already totally unaffordable.

    Even if we take the EVM overhead into account and say it's 100 times less efficient than C++, it's still $14.3 million.

    Disclaimer: I wanted to build on EOS, but turns out it's just impossible, Ethereum is the only dApp platform that actually works.

    EDIT: people call me a liar so I've found some more accurate info. From https://github.com/EOSIO/eos/issues/353:

    Computation - all transactions assumed to consume max quantum (1 ms) of CPU

    So EOS does 1000 tps, 66 times more than Ethereum (15), which means we should adjust the number from the title by that factor: $1.43B / 66 = $21.66M. This much tokens the dev would need to have to run CryptoKitties. 5% yearly inflation would make the real cost $1.08M a year. Considering EOS is centralized, there is no much difference with a $20 VPS, which would only cost you $240 a year.

    Known Sharding Attack Vectors

    Posted: 17 Jun 2018 12:38 PM PDT

    Are there any known attack vectors which we do not yet know how to address or mitigate regarding sharding?

    ELI5 the capacity of sharded Ethereum?

    Posted: 17 Jun 2018 08:14 AM PDT

    The computational capacity of the average node is C. There's no parallelization on Ethereum yet, so the full chain's capacity is C. If I'm not mistaken in my thinking, C is ~15 tps now, or 8 million gas.

    With sharding, there will be N shards, each with a processing capacity of C. Vitalik says that N will be proportional to C. He says that, because of this, the full capacity will be O( C2 ).

    (The big O notation expresses the order of magnitude of the growth of a function, but I don't know too much about it, which may be my point of mistake.)

    But C is proportional, not equal to N. So me layman thinks the full capacity will be O(N×C).

    Now in terms of growth rate, they are probably on the same order of magnitude ( O( C2 ) = O(N×C) ), but in terms of tps, there is a big (a whole order of magnitude) difference. C2 = 225 tps. A general number thrown around for N is 100, which makes N×C = 1500 tps. Note that N could be different, but I suspect it would be probably be greater than 100, not lower (some Casper + sharding notes talk of 4,000 shards, while 15 shards would be pretty disappointing).

    Am I right in my thinking? What are the realistic estimates for sharded Ethereum?

    Legacy Contracts/dapps After Transition to POS.

    Posted: 17 Jun 2018 03:59 PM PDT

    Hey everybody.

    I've read through the Casper v2 document a few times. Very exciting/interesting stuff. But if anyone with a firmer grasp of the consequences can help answer a few questions, that would be swell.

    Firstly, what happens to legacy contracts/dapps from the POW chain? Does everything that wants to remain have to be redeployed?

    And what happens with the history of said contracts when interacting with the new chain?

    I'm still slightly flummoxed as to how this all rolls out, as intriguing as it all is. Hopefully my questions are clear enough and a knowledgeable individual can help satiate my curiosities.

    Cheers :)

    Accessing MyEtherWallet safely?

    Posted: 17 Jun 2018 11:47 AM PDT

    So, a few weeks/months ago, there was this DNS problem with MEW, where hackers could steal your ETH when logging into MEW. I want to send some ETH, but I am afraid I'll lose everything. How can I gain access to MEW safely?

    Ethereum Wallet Has 0 Peers in Light Sync Mode

    Posted: 17 Jun 2018 04:24 PM PDT

    I ran my Ethereum Wallet client in light mode for quite a while to keep the amount of disk space it took up from ballooning insanely (at one point the default config had downloaded hundreds of gigs worth of blockchain).

    I'm used to the light-mode peers being few and far between and occasionally disappearing altogether, but at the moment I'm showing 0 peers and my last block was 12 days ago.

    Is something up?

    (Caveat: My wallet hasn't been open in a while. I'll be more concerned if there's not change overnight.)

    EDIT (~1 Hour Later): Everything is working now. Patience. :)

    Etherpong - Real-time multiplayer pong game empowered by Ethereum (Dapp)

    Posted: 17 Jun 2018 08:11 AM PDT

    www.etherpong.io 1.1

    The world is changing, also the world we knew as gaming is changing frequently together with new technologies. The blockchain is one of those new technologies that we love and want to develop ourselves in.

    That's when we thought let's build the first game ever introduced to man-kind as a inspiration to the first real-time online multiplayer ever introduced on the blockchain.

    Etherpong, a start of a new area within gaming on the blockchain. Etherpong function as a small step for new consumers/interested people to start playing and learning the possibilities and fun that the blockchain carries within.

    The game

    Etherpong is a real-time online multiplayer ping pong game empowered by the Ethereum blockchain.

    The game game exists of two (2) players, player A(1) and player B(2). As a player you can start or create a new game. When creating a new game the player can select a amount of ether (ETH) and the game will be listed for others to join. Everybody who creates a new game with the same amount will be linked into the same game. If player decides to join a game, he/she can look in the existing games and join anyone in the chronologically ordered list.

    Simple user case :

    Player A(1) opens Etherpong, create, input (any amount), transfer, get listed, wait for Player 2(B).

    Player B(2) opens Etherpong, joins, transfer

    Player A(1),B(2) play the match

    end of match, winner Player A(1) or B(2) will take the 95% of total(combined from both players) ether (ETH) played for.

    5% fee will be taken by Etherpong. (Fee will be divided by our policy which is for strengthen the team and improve game(play))

    The contract

    The contract is working as follow :

    Release

    We expect to Etherpong to be ready August 2018 (so really soon!).

    Simple Smart contract help

    Posted: 17 Jun 2018 07:29 AM PDT

    Dear People of Ether,

    I have MEWADDRESS1 that receives ether regularly. I have the private keys to this address.

    Every-time MEWADDRESS1 receives ether, I need it sent to ETHERADDRESS2.

    I don't have programming experience however is their an easy to use tool on a website that can help me develop this kind of smart contract?

    Can I do this without having to learn solidity?
