[harrysolovay]

Closes #19

[michal0mina]

Hi, let me translate what's inside the PR.

This PR represents the configuration of vote counting service.

MIP

This is MIP 5 vote configuration

Time and Date

We see there two timestamps:

"start_time": 1733022000000
it is: Sun Dec 01 2024 03:00:00 GMT+0000

"end_time": 1732914000000
this is: Sat Dec 14 2024 17:57:00 GMT+0000

Only the votes within this time range will be considered valid.
The time range starts 300 slots into epoch 12 and ends 300 slots before epoch 12 end.

Ledger Hash

Currently the field ledger_hash is not configured.
It is a ledger hash which is used to compute weights of the votes.
We need Epoch 12 ledger, which will be published by the protocol around mid November as nextEpochStakingLedger

The next steps

When we fill out ledger_hash the status of the PR changes to Open and then after an approval to Merged. This code change then will be deployed to our On Chain Voting service
