Can you explain this statistic?
It doesn't cost $5.8 in tx fees

Dilution - miners presently receive a reward when they mine a block. Hence, the real cost per transaction is (value of 1 BTC * size of miner reward) + fees / number of transactions. As it turns out, there are relatively few transactions per block and the mining reward is fairly hefty in USD equivalent. Hence, the high cost per transaction. This should go down over time as the currency increases in popularity and the block size cap is lifted.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

There's only one way to deal with spam.  Ignore it.
Perhaps you have something more interesting to do with your time. 

I don't think it's a good idea just to ignore it. this spam may cause some problem to people that is not aware of it.

Correct, this is spam, and how do we deal with email spam? With filters in order to reduce the noise, spam filters have become so effective that only one out of 1000 reaches its destination. So there could be a way to implement something similar in the Bitcoin Core?

I am sure there is a way, I mean I am not a technical expertise, but I am sure this is feasible. The only problem is that the devs are so preoccupied at the moment with the block site increase debate, so things like this will just have to wait.

Until something like this isn't implemented, we should just keep an eye on stress tests like this and include slightly bigger fee when there is one around. This is a current, manual workaround for this problem.

The network proved much more resilient than last time. I had problems with 2 transactions during the last stress test, but I haven't noticed anything during that one. Does anyone know if it was "smaller" than before?

I used to be a citizen and a taxpayer. Those days are long gone.

Memory and bandwidth are limited, of course, at some point we would get steady numbers, just like water can't be heated above 100C in normal conditions.

Are the bastards still spamming the network? I just had a payment of 0.00038306 BTC from a faucet confirmed in less than 2 hours. It was included in this transaction:

That's why a block size limit is not required to get a fee market.

thanks for the warning, OP.
I hate these stress tests. it doesn't even have any benefit for anyone.
I wonder how much BTC they will waste trying to create 1 month backlog...

0.0001 tx cost, lets average 200 tx per block=0.02btc a block.
6 blocks an hour, 24 hours =144 blocks.. thus an average 2.88btc a day in fee's.

then 28 days is about 80btc in fee's.

so if they average 400txs a block.. the cost for the month would be 160btc...
or if they average 200txs a block.. but have a 0.0002 tx fee.. that too would be 160btc.

hope that helps you work out the math

Yesterday I sent some coins with normal fee, they are still unconfirmed. I don't know why miners don't accept yet.
I used normal recommended fee in Bitcoin Core which is 6k sat per kb.

6k satoshi per kb seems a bit low imo, most of the transactions getting confirmed are around 0.0002btc in fees and around 600-700kb in size.

0.00006000 per kb = 0.03600000 for 600kb

so 6ksat per kb is actually quite high!!

But sometimes legit emails are marked as spam (once a professor received one of my emails in the spam folder, I do not know who the hell reported me as a spammer since I never forward stupid mail chains nor spread propaganda, etc.), I mean, how would you distinguish between real (dusty) transactions and spam? If bitcoin is going to be only for big transactions, a lot of people (like me) will forget anything about it.

Well, my comment was just an analogy; I’m not such an expert in bitcoin to try to recommend any kind of solutions. But I still think it’s a good analogy.

tired of waiting for an answer on this thread so I'll ask here.

can someone explain to me why some blocks have small size despite of the huge number of transactions waiting in the mempool?

by the way is it save to say that bitcoin passed this test? I don't see so many people complaining about unconfirmed tx like last time.

A miner can decide for himself how many transactions he wishes to include in a block, if any.
It's perfectly "legal" to "make small blocks" even when there are thousands of transactions waiting.

Yeah, well, I'm gonna go build my own blockchain. With blackjack and hookers! In fact forget the blockchain.

Why do they sometimes not include transactions?
Is it a bug or are they just doing it to be mean?
