Hot take: Fuel is creating a Bitcoin maximalist's nightmare version of Bitcoin: - Native colored coin support - Fraud proofs - Literally on Ethereumhttps://twitter.com/fuellabs_/status/1219020571062808576 …

May I have some Eth sir 0xbE8e5197Acd8597c282D29C066c08A03b657ED08. Thanks Rinkeby!

This is an extremely valuable project. Just because you’re using a smart contract doesn’t mean a system is either decentralized or secure. We need more insight into the security properties and practices of mainnet dAppshttps://twitter.com/chrisblec/status/1222237069516460036 …

4) Community governance: If you need to have an upgrade mechanism which reduces your contract to basically be a multisig, at least make it a big multisig. Rather than keeping control with just the validators, also include users and external oversight boards

3) Allow users to opt-in to upgrades: This one is more application dependent, but if possible allow users to choose whether that would rather move between software versions automatically or manually

2) Use security auditing and formal verification to ensure correctness: Smart contracts have to be considered an area where high assurance is required. You can’t just hope you have no bugs if you’re handling the money of others

1) Have a long delay on your upgrade mechanism: This way users can react to the upgrade and leave the system if it is compromised.

Developers who put in upgrade mechanisms mainly have good intentions. They’re nervous that their code has bugs or want to be able to add awesome features in the future. So what can they do?

Tornado cash is very cool, so not to knock it, and they will do a decentralized ceremony for its proof that will eliminate this issue, but many in the community have been hyping it and getting users to put in funds despite this current risk

Another example of a heavily hyped project: On release Tornado Cash has a fully centralized setup for their SNARK meaning that some entity could easily produce proofs of anything. This is a huge vulnerability in any ZK system with a trusted setup that hasn’t been decentralized

Nowhere in any of those warnings was the huge disclosure: All of your money could be taken at any time if two of the founding team are hacked or go rogue. We have no idea what security precautions they’ve taken to ensure the security of their keys

I believe that as a community we need to stop telling people to put their money in smart contracts with centralized upgrade mechanisms. A ton of Ethereum twitter got excited about PoolTogether and advertised them everywhere trying to attract users

The promise of smart contracts is that we can have trustless execution. Upgrade mechanisms destroy that trustlessness. We need to start building secure contracts today. As a community we need to do better educating developers and users about these risks

The conflict between governance and security in smart contracts is really interesting. Developers want to ensure that bugs can be fixed and improvements can be made. Users want their funds to be safe

Including a mechanism like this means PoolTogether is currently equivalent to a 2-N multisig. Two of the multisig keys could swap out the PoolTogether contract and replace it with anything they want.https://twitter.com/dzack23/status/1221512663588433921 …

Censorship attacks are a risk for many smart contracts including Arbitrum rollup, optimistic rollup, and others that depend on getting TXs accepted within a deadline.

The generalization I usually use to differentiate "useful coins" and "not useful coins" is whether the system needs to be able to tax all participants (mint coins) or permanently punish particular sets of participants (burn).

Ethereum Research (http://ethresear.ch ) has been the highest signal-to-noise ratio place for blockchain research since the days when
#bitcoin
-wizards and http://bitcointalk.org used to be frequented by researchers, and I'm proud to have contributed. I hope it stays that way!pic.twitter.com/SMKtlMzZGv

This is the article I've warned about that is sure to be upsetting. Hopefully it's apparent what is "in scope" for this piece and what's "out of scope". I'd like to propose we discuss *only the ideas being proposed* in good faith, and leave all else aside?https://medium.com/@ercwl/proof-of-stake-is-less-wasteful-b2854a191766 …

My prediction: 2019 was the year of research. 2020 is the year of dope shit shipping. We will see more promising testnet releases in 2020 than we have in the past 3 years combined, and integrations between existing projects will proliferate in our twitter news feeds.https://twitter.com/soonaorlater/status/1207717382107492352 …

Excited about the Fuel beta testnet release and massively scalable stablecoin payments on Ethereum? We just published a post that goes over Fuel’s features, design decisions, and new improvements that are around the corner!
