> they have zero power to do anything related to consensus. Suggest reading what Vitalik has to say if you're going to offer this kind of objection: https://github.com/ethereum/research/blob/master/papers/disc... Infura collects upwards of 80 percent of the fees that flow into Ethereum and is in a position to control exactly who participates profitably. If your solution is "minority will fork" the obvious question is surely "with what scalable infrastructure?"

Quite surprised at this comment. The reason I got into blockchain was _because_ of the incredibly difficult technical challenges it poses. Among the few I get to work on: - How to implement robust p2p networking algorithms for sharding in a distributed system such as Ethereum (a very deep rabbit hole), as Ethereum is migrating to a "sharded" architecture - How to solve the "data availability problem" https://github.com/ethereum/research/wiki/A-note-on-data-ava.... The current solution uses advanced cryptography known as KZG commitments https://dankradfeist.de/ethereum/2020/06/16/kate-polynomial-... - How to solve the problem of "transaction frontrunning", in which miners have an asymmetric advantage in ordering transactions they put in blocks for their benefit, which can adversely affect users creating those transactions. This is a proble

I vaguely remember Vitalik mentioning multiproofs in the context of stateless clients for Ethereum 2.0, but this is what I could find: https://ethresear.ch/t/open-research-questions-for-phases-0-... and the code: https://github.com/ethereum/research/tree/master/merkle_tree I also found a good article introducing multiproofs from Jim McDonald here: https://www.wealdtech.com/articles/understanding-sparse-merk...

`poly_utils.py` in https://github.com/ethereum/research/tree/master/mimc_stark is a fairly simple one-file general-purpose library for arithmetic over prime fields, including multi-point evaluation and Lagrange interpolation; secret sharing and erasure coding are quite easy to implement with these primitives.

The most interesting GH Repo is here: https://github.com/ethereum/research The forum is located here: https://ethresear.ch/ They use gitter instead of slack, I think I misremembered.

I really liked Vlad Zamfir's papers on "correct-by-construction" consensus protocols. What I love about this work is that it unifies traditional BFT consensus with blockchain consensus to make something better than both! Really exciting! Abstract CBC: https://github.com/ethereum/research/blob/master/papers/cbc-... Casper the friendly GHOST: https://github.com/ethereum/research/blob/master/papers/Casp... I found the Abstract CBC paper a little easier to understand, as it goes into more detail about the correct-by-construction process.

Mining power was shown to be overrated by the failure of multiple miner driven or supported proposals and the success of the user-activated Segwit soft fork. The idea of the UASF was that miners would be economically incentivized to follow user nodes signaling and then enforcing new rules - and that is exactly what happen. It is also not out of the question to alter how blocks are mined in Bitcoin - Ethereum is doing that in an upcoming hard fork[0]. With Bitcoin it would be possible to not only introduce a new PoW with a soft-fork, or introduce multiple proof of work methods so that each has a difficulty target and no one PoW has a geographic, technological or regulatory advantage allowing it to achieve more than 100 / number_of_proofs_of_work% hashrate [0] Ethereum is transition from proof-of-work to a combined proof-of-work/proof-of-st

Ethereum's Casper https://github.com/ethereum/research/blob/master/casper4/pap... It aims for more economically secure public blockchains with shorter confirmation times and less cost (electricity/hardware/inflation). I haven't delved deep enough into it to be fully convinced, but what I've gotten through so far is promising. AFAIK its the only proof of stake algorithm thats been formally documented.

People are calling cryptocurrency vaporware, but its only partly true, and definitely not for Ethereum. Check out the hard problems worked on by the ethereum team - https://github.com/ethereum/research/wiki/Problems Each one of those would result in multiple patents if solved by a traditional corporation.

> it's essentially vaporware and all signs point to the conclusion that it will remain that way for the foreseeable future.
