I believe I found the solution.
geth --syncmode "light"connects successfully (in contrast to the deprecated Fether), and so I can use: https://support.mycrypto.com/developers/run-your-own-node-with-mycrypto
but have no peers, how can i config my Node to connect other peers?
Though thinking of mining from https://fxctraders.com/bitcoin-mining/
Is there a way to output a transaction or receipt inclusion proof out of geth? I can only find an endpoint for state proofs: ethereum/go-ethereum#17737
I want sync the block header data from peers
I am checking it it is possible to implement an Ethereum bridge in other Go based blockchains (all Tendermind ones) by using this model how Rainbow bridge is operationg: https://near.org/blog/eth-near-rainbow-bridge/
you need a light client to check the proofs of events happening in another network
We could fit less than 16 ethash DAG elements in one transaction so we had to send them in chunks - this ballooned the number of transactions needed to relay a single ethereum header which in turn means that to stay below ethereum's block rate you need to relax the commitment parameters and submit them more optimistically and/or make the light client accept chunks in any order and keep track of which chunks were missing so that you can send them in barrage.
Rainbow bridge uses https://github.com/tranvictor/ethashproof for the ethash merkelization, and this takes ~3 seconds per block on my machine (though you can cache things in advance if you need)

You also need to do a bunch of keccak 256/512 for ethash verification, so that might require primitives to avoid hitting the gas limit
I can't tell by your message whether you want Go specifically, but there are Tendermint/Cosmos SDK ports to other languages - I've used an Haskell one in the past
Meaning, there's probably a Rust Tendermint SDK you could use and leverage a good deal of rainbow bridge directly
This is especially embedding a Ethereum light client in TenderMind based chains (all Go)
I only need to verify event logs in a Go based program
one way
so any communication would need to happen over Ethereum transactions (expensive)
@alesito85 which network do you run ? I faced with this problem on ropsten network. Couldn't find any peer for several hours. Got lucky to find this peer enode://23fd0ff45034abb96933c07b4fa9e2aff5029f78ec27a425a2547990b59cffb1e8f87b6ae4a88d2fc4b6f3d57b67673fa3d4df1c893f2cc72ddf37ef75c21a00@178.128.242.69:30303
for main network all works fine
there are opened to light client nodes
Hello! What are the differences between the ethereum full node and the light node? I am interested in specific functionality, that is, generating addresses, obtaining information about a transaction by hash, etc. Is there any functionality that can be lost when switching to a light node?

Hi,
testing
geth --syncmode light ...
working ok, synchronization taking some few minutes.
However when closing client and restarting it, finding following issue that cannot solve by now, without a fresh (on clean datadir) resync
... err="block in the future"
Main concern is that always having a fresh light sync will eventually miss i.e transactions done today in say 1 month (assuming that's the time window for light mode)
Please, looking for advice for workaround
The one given on the ethereum website is very high level and does not talk about the datastructures or pseudo code.
month late lol
everyone is optimistic about the rise and fall of the cryptos. personally, you can all agree with me that the bitcoin price is going to exceed its current value to $71,415 in February 2022, panelists have also predicted the bitcoin price to skyrocket to an average of $249,578 by the year 2024 which could also influence the price of altcoins. it's never too late to buy and hold of Ethereum/Bitcoin now is the right time. I personally have sustained over $567,000 since last year still now copying advance trade signals and indicating stop lost and manage risk following a mentorship and a blockchain specialist https://declanbrock.com/ his pattern are very lucrative with full of complex.
