<Jochem Brouwer> Actually it seems to be at end of Tx per the yellow paper
<Jochem Brouwer> In retrospect I should've known the VM was correct since pre-Byzantium tx receipts also include intermediate state roots. Those tests would fail if the reward would be applied after every tx was executed 🙂
anybody has a zoom link?

<Jochem Brouwer> "The core of the trie, and its sole requirement in terms of the protocol specification, is to provide a single value that identifies a given set of key-value pairs, which may be either a 32-byte sequence or the empty byte sequence." -> it should be 32 bytes per yellow paper
Makes Deep branch attacks difficult (as difficuly as mining)
<Jochem Brouwer> Ah wait I am still confused. If I would
PUSH1 0x01 PUSH1 0x00 SSTORE STOP (write the value "0x01" to storage slot "0x00") what is written? I am particularly interested in if 0x01 is left-padded so it is 32 bytes. Or in other words what if I would PUSH32 0x0000..01 PUSH1 0x00 SSTORE STOP would this be (semantically) the same?
<Jochem Brouwer> And internally in the trie this value is actually first RLP-encoded?
I think the value is RLP encoded twice before it is added to the storage trie, but I don't remember very well now
As @shemnon noted, keys are left-padded, then Keccak256-ed, values are trimmed, double RLP-encoded, and then the pair of key (the remainder, not the whole key) and the RLP encoded value, gets RLP encoded again :)
there is a lot of RLP encoding going on there, i can tell you that...
<Jochem Brouwer> Thanks a lot! Do you have a reference somewhere about this value trimming? I can't seem to find it in the Yellow Paper 😓
<Jochem Brouwer> (Code reference is fine too)
<Jochem Brouwer> What is the exact reason why we KECCAK the address in order to get the key to put it in the MPT? Now if I traverse the MPT I can find all accounts, but I don't know which address it belongs to (unless I have a lookup table). What is the reason to KECCAK the addresses?
<Jochem Brouwer> I see now! Thanks!
<Jochem Brouwer> (I read the response but did not understand the implications). Should have asked more 😅
<vbuterin> Cross-posting this here:
<Souptacular> @vbuterin did you post this in the new #allcoredevs channel in the Eth R&D Discord? This Gitter/Telegram bridged ACD chat is deprecated.
<vbuterin> I did not!
<vbuterin> I was looking for that channel
<vbuterin> Will repost
Hi. Apologies if this was already mentioned here (did a search) or Twitter, but there appears to be a "Max Price" gwei limit in Geth clients. Gas prices are quickly approaching that limit, according to https://ethgasstation.info/. I've already brought it up in the Geth Discord, as well as tagged Peter Szilagyi, just in case anyone here could verify there's a team already looking into it.
That limit is 500 Gwei: https://github.com/ethereum/go-ethereum/blob/master/eth/gasprice/gasprice.go#L33)?
@/all Reminder! Please migrate from this channel to the Eth R&D Discord server where we have a #allcoredevs channels.

Has anyone come across this error when trying to connect to their local geth node via rpc?
