    Are Stateless Clients a dead end?

    Posted: 10 Dec 2019 10:30 AM PST

    Porting this conversation over from Twitter because it deserves more participation/visibility.

    https://twitter.com/peter_szilagyi/status/1204439329889751045

    Péter Szilágyi (/u/karalabe/): "Can we please stop selling stateless client as a viable solution? Nobody managed to demonstrate feasibility at all over the past 3 years. Proving a single mainnet block updates (reads excl) is 1MB, over an order of magnitude larger than the block. There's no bandwidth for that."

    Discussion ensues.

    If stateless clients are in fact a non-starter based on current bandwidth limitations, this has outsized implications for both the ETH 1.X and ETH 2.0 roadmaps. The former has set aside state rent as a solution to address state bloat (in favor of stateless clients), while the latter relies on stateless clients to handle the challenges of validators operating on randomized shards.

    Some background/additional color on these challenges can be found here, in this July post by John Adler and subsequent discussion: https://ethresear.ch/t/open-research-questions-for-phases-0-to-2/5871/2

    Key questions to ponder:

    - Are stateless clients actually infeasible given the current architecture and limitations? Or are Péter's concerns perhaps overstated here?

    - If so, could a redesigned merkle proof make it work? And if so, what are the next steps and challenges around that task?

    - If stateless clients are in fact not viable, what does that mean for ETH 1.X and ETH 2.0? 1.X might have to adopt state rent after all, with breaking-change warts and all. And for 2.0? That would change very fundamental aspects of the planned architecture and require some serious rethinking/respec'ing.

    Enigma Discovery implements the EEA Trusted Compute Framework for public Ethereum

    Posted: 10 Dec 2019 08:17 AM PST

    Enigma has published an overview of how the Discovery network implements and builds on the EEA Trusted Compute Framework, bridging public Ethereum with enterprise requirements for data privacy. From the post:

    The Enterprise Ethereum Alliance has identified the need for trusted and private computation as a requirement for enterprise use of blockchains and has developed the Off-Chain Trusted Compute Specification (TCS). These specifications have been demonstrated by a reference implementation for Hyperledger called Avalon, which is currently available in Version 1, with Version 2 currently under development.

    Enigma has implemented the TCS specifications for an Ethereum-compatible, decentralized network — the Enigma Discovery network. This release is open-source and has been in developer release since June 2019.

    In addition, Enigma has begun actively contributing to the specifications of the TCF Version 2.0. Enigma's implementation of TCS introduces several contributions that are not yet included in version 1 of the TCS (such as encrypted state), and demonstrates implementations that are described but not included in Avalon, the reference implementation, such as a fee market for computations.

    TCP/IP and Ethereum

    Posted: 10 Dec 2019 07:33 PM PST

    Can someone explain with as much detail as possible how a transaction is "broadcasted" to the network?

    I have a pretty good technical understanding on how the internet works, OSI model, TCP/IP etc, but I have not found any decent resources on how a broadcasted signed transaction goes from my home router to the blockchain.

    A visual representation of the actual connections made would be awesome.

    Front End vendors for DAO’s

    Posted: 10 Dec 2019 04:45 PM PST

    So, I'm wondering what kind of front end sticker/tshirt vendors exist that would cut payments to a DAO agent or if this is a niche that hasn't been filled yet.

    Source Code - Platform behaviour during transaction

    Posted: 10 Dec 2019 01:29 PM PST

    Hey ethereum subreddit,

    I am still writing my thesis on ethereum. I have one chapter that is supposed to concentrate on the behaviour of the Ethereum platform when a transaction is triggered. Here I am struggling.

    My prof wants me to check in the source code what happens and what functions are executed when a transaction is executed.

    I am a little bit lost here as I am not particulary good in reading source code (even though the go- ethereum code on github is very well structured).

    Does anyone of you could give me some clues on where to start here? Are there particular packages where I might find answers?

    Thanks a lot guys for your support so far :)

    Private Keys Exposed by Accessing Theta Web Wallet?

    Posted: 10 Dec 2019 11:56 AM PST

    I left my tokens and Ledger Nano S for a while.

    I come back to see Theta has moved to the main net so I missed the swap. Looking around I found that i still could access my ERC20 Tokens via https://wallet.thetatoken.org/unlock/cold-wallet

    I see to access my ERC20 Theta that website asked for private keys except for Ledger devices.

    I did have a look at my Theta ERC20 via the above link. Were my ETH or any other private key extracted and exposed?Would I have to create another mnemonic and shift my tokens to new address created via new mnemonic?

    Gasless desktop wallet that is not cookie/website-based?

    Posted: 10 Dec 2019 04:40 AM PST

    If I want gasless transactions on desktop and I don't want to use a cookie/website wallet (like Portis), what are my choices? Are there any browser extensions of standalone wallets that support it?
