Idea: integration TRON Lite FullNode about shkeeper.io

[dmytro-samoylenko]

Hello,

On the first start the wallet receives last block from fullnode server and scans blockchain starting from received block number.

You may replace block number in the db using mentioned command, make sure you stop tron-shkeeper before adjusting the block by running kubectl -n shkeeper scale --replicas=0 deploy tron-shkeeper and then start it again with kubectl -n shkeeper scale --replicas=1 deploy tron-shkeeper.

Hello,

Actually you already can use a Lite Fullnode snapshot (e.g. from http://47.89.178.46/backup20230503/) with tron fullnode that is deployed by Shkeeper chart (starting from chart version 1.2.36 and java-tron image version GreatVoyage-v4.7.1.1).

Please let me know if you need a detailed description how to run Lite Fullnode instead of regular Fullnode.

Yes, if you don't mind
I would like to get information on how to configure values.yaml for Lite FullТode for TRON and ETH

I tried to set it up myself but failed

If you have Tron fullnode or light fullnode outside of cluster you need:

tron_fullnode:
  url: http://<external-fullnode-hostname>

If you want to have lite fullnode in cluster, you start with:

tron_fullnode:
  enabled: true

Download latest lite fullnode snapshot from http://47.89.178.46/:

wget http://47.89.178.46/backup20230503/LiteFullNode_output-directory.tgz

Unpack it:

tar xzvf LiteFullNode_output-directory.tgz

Stop java-tron:

$ kubectl -n shkeeper scale --replicas=0 deploy java-tron

Delete all blockchain data:

rm -r /var/lib/rancher/k3s/storage/pvc-<......>_shkeeper_output-directory/*

Copy blockchain database from archive to pvc:

cp -r output-directory/database /var/lib/rancher/k3s/storage/pvc-<......>_shkeeper_output-directory/

Start java-tron:

$ kubectl -n shkeeper scale --replicas=1 deploy java-tron

I haven't found a way to use Ethereum fullnode in prune/lite mode. Looks like lite node is broken after the Merge and prune mode is not implemented yet.

thanks, it works!
I did everything as you indicated. even the transactions that I made this week have already been displayed. but the wallet is still in the process of syncing and constantly downloads something over the network

is this normal, will it continue like this?
Sync In Progress (51028546 blocks behind)
it seems to me that this is not normal, because I have specified a remote node that is already synchronized

it is not at all clear why he writes that (51028546 blocks behind) when the current block is 50882219
why is there such a large number of blocks. when are there fewer blocks in total?

Hi,

Perhaps tron wallet last seen block was set to 0 and now it catches up. You may check it with:

# sqlite3 /var/lib/rancher/k3s/storage/pvc-65d64be9-b08f-4815-9afa-a02efdcc6ab9_shkeeper_tron-shkeeper-data/database.db 'select * from settings'
last_seen_block_num|50893163

If it is too far in the past you may adjust it by running:

# sqlite3 /var/lib/rancher/k3s/storage/pvc-65d64be9-b08f-4815-9afa-a02efdcc6ab9_shkeeper_tron-shkeeper-data/database.db 'update settings set value="50893163" where name="last_seen_block_num"'

50893163 is a latest block seen by my wallet.

[bulhiCzar]

I got this result

last_seen_block_num|94361
current_server_id|0

this means that now the wallet is located on 94361 blocks, which was many years ago. even though I downloaded LiteFullNode and it didn't apply automatically?

I need to install the right block from which I want to start syncing. and it will start syncing exactly from the block that I specify?

I'm sorry that I ask so many questions, I just want to make sure of my actions
