    Why uncertainty about Ethereums PoW algorithm should be welcomed

    Posted: 03 Feb 2019 07:38 AM PST

    1. One of Ethereum stated goals is the switch away from PoW to PoS

    2. As long as we rely on a PoW algorithm we have to incentivize miners to secure the network

    3. Miners have to invest in hardware to secure the network

    4. GPUs were the most efficient way to secure the network for a few years.

    5. With the release of Ethereum specific ASICs GPUs are not the most efficient way to secure the network anymore.

    6. Nevertheless, it is still profitable for miners to mine on the Ethereum blockchain; the status quo is more or less okay for miners or they wouldn't continue mining on Ethereum.

    7. It's a possibility that the next generation of ASICs will heavily reduce the profitability of existing hardware

    8. As a result GPU Miners are worried about their investment, while participants in the Ethereum Ecosystem are worried about decentralisation

    9. Switching to another PoW algorithm can be contentious, as seen in the current ProgPoW debate

    10. BUT as long as there is uncertainty about Ethereums mining algorithm / mining rewards the incentive to develop Ethereum specific ASICs is relatively low.

    11. It doesn't seem completely absurd that a productive, ongoing debate about the mining algorithm without switching to ProgPoW is the sensible choice. The possibility to switch to another PoW algorithm may already be enough to hinder further ASIC development

    12. If this shouldn't be the case then a switch to a heavily audited, but not yet implemented, algorithm is easier and potentially less contentious than right now.

    tl;dr: Ethereums current form of governance (endless discussion) is a good enough deterrent for further ASIC development without being overly contentious.

    Maximum (practical, gas defined) limit on Solidity / EVM address array size

    Posted: 03 Feb 2019 08:00 AM PST

    Check out the smart contract below (not tested), I understand that the maximum array size is 2^256-1, but I'm thinking block-gas-limit will stop it growing long before that.... What is the practical limit - approximate?

    contract unmissableParty { address[] public partyList; function addMe() public { partyList.push(msg.sender); } }

    Quick question about the logistics/algorithms behind Eth-JS wallet/keypair generation tool

    Posted: 03 Feb 2019 10:54 AM PST

    Quick question on the Eth-JS utility that has a wallet generation tool. Does anyone know offhand how "random" wallet keypairs are generated?

    ​

    i.e. is it (functionally) random enough that, in very, very, very, incredibly rare circumstances, one could theoretically generate the same keypair twice in a row (would never, ever happen, but theoretically)? Or is it set up to be much more deterministic, such that you'd have to run through literally every keypair once before they started to be recycled?

    ​

    I'd also love any resources on how these ethereum libraries work behind the scenes... really interested in learning but haven't found a good resource yet!

    Thanks!
