same results using
FrontierVM https://pastebin.com/EzzDzAEW ... I should stew on it for a while. I appricate the help.
<carver, Jason Carver> That one should be working, has the
MiningChain, etc. Then we can work backwards from there to find the first intermediate step that seems broken.
<carver, Jason Carver> Looks like the plan is to move this channel over to this at some point soon:

<carver, Jason Carver> We'll keep monitoring this channel for a while, and there will be more reminders before this channel goes dark. But for anyone who prefers, they can head over to Discord now.
Hi, short question here, since I couldn't find anything to that topic online: Is it possible, to access Py-EVM remotely? For example, I want to have to processes, one providing the blockchain using Py-EVM, and another process (the client), which accesses the Py-EVM blockchain via Web3 "remotely" (same host, but another process)?
<carver> @keri @Felipe Selmo (fselmo) Ok, the London tests don't pass. Still something pretty fundamental since there are 5391 failures. It looks like most failures are about gas usage, so I think it's something other than EIP-1559, but I haven't dug in yet. Seems like a good exercise for everyone to take a look. ethereum/py-evm#2021
You can fetch this branch for local runs. It allows you to run
You can fetch this branch for local runs. It allows you to run
pytest tests/json-fixtures/blockchain/test_blockchain.py --fork London --maxfail 3. The branch should skip the slow tests, and let you see a couple failures before exiting (rather than wait for the full suite, which can be quite long, even when skipping slow tests)
Can't wait for this update :). FWIW, wrote up the specific issue that I'm running into right now: ethereum/py-evm#2042. The transaction validator seems to currently be rejecting London transactions with v=0.
i want to develop a blockchain like ethereum from scratch for a project
is this the right repository for me? can i write and deploy smart contracts in it? will the smart contracts be written in python as well?
Hello! I have a question in regards to code execution in the EVM, specifically I wanted to know if I could run complex programs, like per say, a web scrapping or a data processing task.
If that is not possible to run on the evm, are there any other chains that allow for this type of distributed computing. Are there any resources I can read up on that?
Thank you

The EVM is a strict sandbox environment and quite restricted. It can't communicate with anything outside of the immediate transaction and contract state that it's in. No block chain offers anything beyond this that I'm aware of. What you're describing requires a completely different system architecture.
Tonight at 7p BKK (GMT+7 about 1.5 hours from now) we're giving a little presentation about evaluating EVM Block Chains from a Biz & Development perspective. Please join us on our multi-way live streaming platform and feel free to offer comments/questions during the event.

<carver, Jason Carver> @anshulforyou The default
MainnetChain is not a MiningChain, because py-evm is nowhere near optimized enough to mine on mainnet. If you want to try anyway, you could build a version of Mainnet that inherits from MiningChain. To get started, here is the default mainnet chain definition: https://github.com/ethereum/py-evm/blob/master/eth/chains/mainnet/__init__.py
<carver, Jason Carver> @P1erreM_twitter we don't serve json-rpc from py-evm. That was handled in Trinity, which is shelved.
I am very new to the forum
Is there a way to get the address of the smart contract you just deployed?
<carver, Jason Carver>
contractAddress in the receipt of your deploying transaction will have it. See: https://web3py.readthedocs.io/en/stable/web3.eth.html#web3.eth.Eth.get_transaction_receipt
Question: I'm trying to make a local contract call to retrieve a return value. The function that I'm invoking checks to see if an address is within a set of addresses, returns true if so. However, when I try to execute the contracts bytecode with the necessary arguments, the computational object only returns the contract's bytecode as output. How can I get it to return a boolean value as expected?
P.S. the LynxComputation object is just a fork of the FrontierComputation class. Also, please don't suggest using Web3.py because this has do to with a new blockchain I'm trying to make which I don't think will work with Web3. Thanks!
<Felipe Selmo (fselmo)> Good question. There's definitely less chatter in here these days compared to the Ethereum Python Discord (https://discord.gg/GHryRvPB84). There is a
py-evm channel there as well. It's easier to localize conversation in one place and there was a lot more presence there, for better or for worse.
<carver, Jason Carver> There is not a proper full node. The previous attempt was trinity, which is no longer supported. But if you just want to run test transactions against a local development network, you can use eth-tester, with py-evm under the hood. See: https://web3py.readthedocs.io/en/v5/providers.html#ethereumtesterprovider
