Coding Theory – Calculation of the probability of $ k $ errors in a $ q $ repetition code over a symmetrical channel

I read something about coding theory and have difficulty understanding the error probabilities in $ q $Repeat codes. What I am particularly concerned with conceptually is solving problems of the following kind:

ON $ q $-ary repeat code is transmitted symmetrically
Channel, with some probability $ p $ that there will be a little mistake.
What is the probability that it will be $ k <q $ Error with
Transfer code word?

I've seen formulas for certain examples with defined ones $ q $. $ k $, and $ p $, but I can't really deal with the general approach to a problem like this.

Where can I find similar channels to a specific channel in telegram?

On Instagram (web version), you can use this button to display a list of suggested pages that are similar to the current page. This makes it easy to find many resources on this network.

Is there a similar function somewhere in Telegram? I want to find channels that are similar to the current channel I am in. But I can't find how.

Blitz Network – Can failed transactions find out which channel is exhausted?

According to this LND PR, the sender is one TemporaryChannelFailure can be determined:

In many cases, the sender cannot determine which of the two nodes in a pair is responsible for the failure. In this situation, we now punish bidirectionally. This does no harm to the couple's good knot as only its connection to a bad knot is punished.

So my understanding of this comment is that the channel or at least the node next to one of the exhausted channels can be identified fairly easily. Is it really that simple? Can TemporaryChannelFailure and thus channel exhausts are always assigned to two nodes or one channel?

I have always assumed that the error cannot be assigned to any node or channel at all.

This could make some work easier, such as: The difficulty of hiding the balance

Blitz Network – What happens to the Bitcoin blocked in the payment channel if both sides lose the backup?

As far as I know, there are two types of backups. On-chain backups that store the keys of your on-chain funds, i.e. the on-chain channels, and the on-chain funds in the Lightning implementation. this is that hsm_secret File in C flash. The other backup is the channel status in which the delivery transaction status, lock keys, etc. are stored lightning.sqlite3 File in C flash.

If you lose your backup from lightning.sqlite3 File you basically have no insight into your current commitment status in the active channels you have. Your strategy should be to separate your knot so that the other parties unilaterally close the channels they have with you. However, since you mentioned that your channel counterparty has also lost their backup, you cannot use this option.

Since you both don't know what the current commitment status is and who owes what amount, it's best to negotiate with your counterparty and do an on-chain transaction to close the channel. Since yours and partner’s hsm_secret File is secure, you can make the on-chain transaction and recover the funds. You need to derive the keys from the file, but this has to be done in a user-defined way, as the implementations cannot do this alone.

If you lost yours hsm_secret and lightning.sqlite3 File, then there is no way to recover the funds. Since you have basically lost the keys to the on-chain funds, you have But this is in the same boat as the loss of the wallet.dat File in Bitcoin Core.
