I am writing a smart contract where I am storing data in map, will the tx fee and gas increase for txs as the size of the map increases?

Hello
My transaction on ether scan is pending since 10hours i suppose i made a mistake with the gas fes
Is there any solution to complete the transaction ?
DeepalUsyD
@DeepalUsyD
I think you should send the same transaction again with the same nonce and a higher gas price
This should replace the pending I think

How can I figure out what is going on with ropsten? They did reorg on friday and now etherscan says last block was mined 29 minutes ago

hello, everyone. When the Ethereum node is updated, if the update is a new hard fork, the chain configuration information of the new version node includes the hard fork configuration information, but the old node chain configuration information does not. So after replacing the old node with the new node, do I have to synchronize the block data from the beginning? Can I just update the chain configuration information of the database and keep the synchronized blockchain data?

does anyone know how to get a prestate file for the t8n tool? (https://github.com/ethereum/go-ethereum/tree/master/cmd/evm)
François-René Rideau
@fare
@sivaswati_twitter do you still need rinkeby ethers?
@DeepalUsyD do you have an issue where you actually reuse addresses when you think you aren't? Maybe a bad PRNG?
Be careful: a bad PRNG can totally defeat your security.

Hey guys, do you know of any templates for a Geth node on Azure? Or good tutorials? Would like to host geth, ip whitelist a server, and access main, kovan and other networks from there.
AusIV
@AusIV
@victorwiebe - I don't have an Azure template, but you're not going to connect to Kovan from Geth - only Parity/OE supports Kovan.

Hi, anyone see the error like "got null header for uncle 0 of block 2a4824edbd712d3cd56a3b85cc538d884a887cce059fb44a5c0d34782353dce4" when querying a block? Any idea what does it mean?

Hello. In geth I'm trying to figure out how what algorithm.hashimotoFull returns is used to generate the next block during mining. It takes the "hash", and then returns the digest which is assigned to header.MixDigest in sealer.Seal. Where does the new "hash" for the next block come from?
The digest/header.MixDigest returned by hashimotoFull doesn't seem to match anything in the block or next block if I use the block's hash and solved nonce as the input.
I've tried first and latest epoch using 1.9.20-stable

Hi all, if I can abruptly ask a question here:

geth --syncmode "light" getting stuck at:

INFO [09-11|19:11:43.053] Mapped network port proto=udp extport=30303 intport=30303 interface="UPNP IGDv1-IP1"

Have tried resyncing clock, deleting chain data, double and triple checking 30303 is open. No luck. Any ideas?

@0xEther_twitter
Ok so digging deeper it looks like it's tricky to connect to peers as a light client. I'm using a list of 12 enode addresses but even that is failing me. Is this just something light clients have to deal with? I just want to fork mainnet and test some contracts.
Marius van der Wijden
@MariusVanDerWijden
@0xEther_twitter Unfortunately yes, there are currently to little full nodes that serve light nodes.
If you run a full node you can use --light.serve 200 to enable the light server that lets light clients sync off your node

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?

I'm trying to import rlp file with a newer version of geth and get invalid difficulty error, is there a way to get around it?

Do you have only one node, or is there at least one node that didn't run out of space from which to recover?

Hi ! Running a geth node, I need to keep the states of the last 2 weeks only. I synchronize it in fast mode, then once done my understanding is that only last states are kept. Looking at the doc, it seems possible to set this value
"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."
Kurth Alexandre
@kurthalex_twitter
does it mean that I need to sync archive mode from the beginning ? Or is it compatible with fast sync
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 :-)

nope, its actually a project we took over and there was only one node that we intend to replace with authtrail eventually

AusIV
@AusIV
@kurthalex_twitter - You can fast sync, then restart your node with --gcmode=archive - I do it all the time

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?
Marius van der Wijden
@MariusVanDerWijden
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.
