Hi, everybody. My task is to create a system on the blockchain in which you can exchange different goods. I am currently studying the possibilities of Ethereum. It is assumed that instead of nodes there will be warehouses, instead of currency there will be different goods. Warehouses goods will be exchanged. Is it possible to create such a system on Ethereum? Or is it better to look in the direction of Hyperledger? So far, everything I watch about Ethereum about currencies and about mining. But I don't need mining at all. Maybe someone has seen an example or tutorial like this, I will be glad of any useful information. The topic of blockchain is still new to me
hi, we are running a private chain on an old geth version and the VPS run out of space and now we lost a few blocks, I was reading the issues and found issue #19124 that has the same problem, the problem was fixed on a PR fro 1.9 but there is no definitive answer of getting blocks back
would a restore to an updated geth solve the issue?
"Geth will regenerate the desired state by replaying blocks from the closest point ina time before B where it has full state. This defaults to 128 blocks max, but you can specify more in the actual call ... "reexec":1000 .. } to the tracer."
Has anyone already tried to change this value ? I don't find examples of commands
Also, the line after in the doc it is written : "Sorry, can’t be done without replaying from genesis."
So my question was to keep the states of the last 2 weeks, but I've also another one, maybe simpler. Is it possible to begin to keep all the states of a node, starting from now. i mean, I don't need the past 5 years of states, juste need to keep states from now.
Can I fast sync, then stop the node, and launch it again in archive mode ? so that states will be kept ? Just don't want the node to restart to process and store state from the beginning
thanks :-)
Hi! I have several pending transactions from the same account with low gas price. What if I'll send one more transaction with next nonce but high gas price? Can it help to mine all pending transactions queue behind last "expensive" transaction?
If it doesn't work than next question is how to include "self" transactions in mined block with geth?

No you need to resend the pending transactions with a higher gas price. Transactions can only be executed if all previous transaction were executed.
What do you mean with "self" transaction?
Geth automatically assembles the block for you and sets the coinbase address if you mine with it.

Does anyone know the cause of this error ?
So I have a fully synced geth node running right now, but I can't geth attach to the websocket. Has anyone had an issue like this/knows how to resolve it? When I first started geth I set up the ws flags: --ws --ws.addr localhost --ws.port 8546 --ws.api personal,eth,web3,admin,txpool,debug
Makes no sense to me! If anyone can shed some light on this issue that would be great and much appreciated. I can't connect to ws over web3 on my node either!
Provided, of course, that you don't reset the DB or anything like that!

perhaps GetRawTransactionByHash at https://github.com/ethereum/go-ethereum/blob/ec8ee611caefb5c5ad5d796178e94c1919260df4/internal/ethapi/api.go works?
Let me explain. Is it possible to include own out transactions to next block will be mined on my node?
I want to save money on fees from pool payouts
Like big pools do

In another words how to include specific transaction in block?
Hi friends, I have a quick question here. I hope some could help me out.
I am running a local Geth full node, with "--rpcapi eth,net,web3,txpool". Running uniswap local is working excellent. Running balancer pool information it gives me errors JSON RPC. "Failure querying onchain balances" . Running a infura node in balancer and everything's works. Am I missing some arguments for my local node? Maybe wss ? Could someone post me an example? Also I want graphql enabled so I can run a local blockchain. Thanks

running into an issue with a Geth node I'm running on Kubernetes. The discovery port is set to 1024 instead of 30303 as is standard and intended in this case. I'm now explicitly passing in the --port=30303 flag, but it's not resolving the issue. I'm using a persistent disk for the chaindata, so I'm thinking there's some config file where I could modify to change the discovery port back to 30303 manually there. Is this the case? And where would I find this file/setting? If not, any other suggestions for how to resolve this issue?
Hello, would someone have a solution for this problem ?
https://ethereum.stackexchange.com/questions/88167/pending-transactions-logs-issue
@_Anarz_twitter logs are not saved in the DB until the block is fully formed and mined so there is no native way to access logs of pending transactions - one solution i can think of is making a modified endpoint which will be similar to
eth_call but will return the full execution result (and maybe some other things) rather than just the rlp encoded return variable
@thor-ragnarok Thank you for your answer. So the logs are not saved in the db and therefore are not accessible by the API but they do exist, don't they? Insofar as the pending block is created by the node on which mining is activated, it must have "simulated" the execution of these transactions and therefore have generated logs that are located somewhere, right?
