δεν πειράζει. Με πλήθος συναλλαγών κρασάρουν τα BU node  |

εγώ νομίζω ότι έχουν πλέον και σοβαρό νομικό πρόβλημα. Στις περισσότερες χώρες της Ευρώπης μη πω σε όλες αλλά και στις Ηνωμένες Πολιτείες νομίζω είναι παράνομο να προμηθεύεις υπολογιστές με backdoor ώστε να κάνουν tracking τους πελάτες.

παιδιά η συναλλαγή δεν ακυρώνετε. Απλά αν περάσουν πολλές μέρες μπαίνει εκτός mempool και τότε μπορείς να την ακυρώσεις με command στην γραμμή εντολών. Το multibit έχει νομίζω τέτοιο commant.

Πριν λίγες ώρες αποκαλύφθηκε πολύ σοβαρό backdoor που φέρουν όλα τα bitcoin mining mηχανήματα της Bitmain. Συγκεκριμένα τα Antminer mining μηχανήματα της Bitmain κάνουν κάθε δέκα λεπτά check-in σε ένα κεντρικό server που ελέγχεται από την Bitmain αποκαλύπτοντας το serial number, τηνMAC address και την διεύθυνση ip τους. Ο κεντρικός όμως αυτός server μπορεί οποιαδήποτε στιγμή να γυρίσει ως false αυτό τον έλεγχο και να σταματήσει την λειτουργία του μηχανήματος. Με λίγα λόγια όχι μόνο η Bitmain αλλά και κάποιο που πάρει τον έλεγχο αυτου του site μπορεί ανα πάσα στιγμή να ρίξει το 70% του bitcoin mining δικτύου. http://www.antbleed.com/The Antbleed Backdoor
Antbleed is a backdoor introduced by Bitmain into the firmware of their bitcoin mining hardware Antminer.
The firmware checks-in with a central service randomly every 1 to 11 minutes. Each check-in transmits the Antminer serial number, MAC address and IP address. Bitmain can use this check-in data to cross check against customer sales and delivery records making it personally identifiable. The remote service can then return "false" which will stop the miner from mining.
The patch was introduced here (pastebin) and can be seen in the source: here (github)
How bad is it?
At worst, this firmware backdoor allows Bitmain to shut off a large section of the global hashrate (estimated to be at up to 70% of all mining equipment). It can also be used to directly target specific machines or customers. Standard inbound firewall rules will not protect against this because the Antminer makes outbound connections.
Even without Bitmain being malicious, the API is unauthenticated and would allow any MITM, DNS or domain hijack to shutdown Antminers globally. Additionally the domain in question DNS is hosted by Cloudflare making it trivially subjected to government orders and state control. Νομίζω πλέον κάτι πρέπει να γίνει και είναι δεδομένο ότι οι miner είναι κίνδυνος για το ίδιο το Bitcoin δίκτυο. https://bitcoinmagazine.com/articles/bitmain-can-remotely-shut-down-your-antminer-and-everyone-elses/ |

γιαυτό καλό είναι να χρησιμοποιούμε πορτοφόλια είτε που βάζουν δυναμικά fee είτε που σου δίνουν την δυνατότητα να αυξήσεις τα fee στην συναλλαγή. Κάτι τέτοιο το κάνουν ήδη το electrum και το greenadress.
πόσα fee έβαλες ακριβώς?

LN is NOT, repeat NOT a scaling solution. It is a nice-to-have thingy to make micropayments, so people do not have to resort to DOGE or LTC to pay for coffee. Like a corporate gift card from Starbucks or whatever... We still need a real scaling solution and bigger blocks. LTC's Charlie Lee has promised it, for BTC a promise is not enough. It must be in the code. I suggest locking BU devs and Core devs into a bunker and not let them out until a satisfactory compromise has been created  BU has developers? |

and then if anyone agree that micropayments can solved from LN what we need a block size increase? As i say even if bitcoin price double bitcoin is again very cheap,. 1-2$ for fees to transfer money is ridiculous cheap.
1. onchain fee's of $1-$2 .. your thinking about corporate america.. come on look beyond your window.. $1-$2=>20 labour hours in multiple countries think about the unbanked!! 2. LN has limitations. Eg lets say you just want to deposit $60 for microtransactions.. to open-close = $2-$4 = 3-6% (ps even the LN architects are suggesting only using $60 amounts due to a few risks that LN has (blackmail, chargebacks, address reuse attack) 3. LN although can be open for a year. think real worls usage. can you predict how much you would need to spend each day, beyond say 2 weeks..(ps even the LN architects are suggesting only using $60 amounts, for a 2 weekish lock-in due to a few risks that LN has (blackmail, chargebacks, address reuse attack) so knowing people are only using it on average for just some of thier funds (not whole hoard) and for a couple weeks (not eternity) then you start to realise that even though xapo, coinbase, changetip all have internal offchain 'swapping' .. onchain capacity still needs to grow to cope with the depositing and withdrawing and also the 'larger spends' please note that saying people should lock their entire hoard into a channel for eternity shows that your not looking at the reality, risks and limitations but trying to create a utopian and false hope narative. onchain scaling needs to grow because LN will just help services like shapeshift/xapo.. but those peopl paying rent or travel or fortnigtly groceries will still be onchain and fighting for room alongside all the LN channel open-closing. you still talk crap and you dont know nothing about it. USA is not the center of the world.  |

give this facepalm to your beloved boy Roger Ver. He claims that bitcoin is an everyday coffee payment system. I personal see bitcoin as it is. A decentralised payment system to store value and to transfer value around the world without the needing of the banking system.
get passed the reddit scripts. you will find that many are ok with LN as a side service. such as xapo is. such as coinbase, changetip, and shapeshift is. for the faucet, day trader, gamblers.. but not as a REQUIRED service for all pools dont give a crap about LN, neither do the other implementations. its reddit scripters insinuating what pools and other implementations want. again LN as a voluntary side service is acceptable.. but NOT by pushing the fee's up by holding the blocklimit hostage with false promises and removing the reactive fee's to force everyone into permissioned commercial hub services and i think is clear that you are the one here that has obsessions. I only follow the tech facts and believe to the best tech proposal. I have not change to this. I only want my value to bitcoin to be safe and usable in long term. |

Νέο ATH σε όλα τα ανταλλακτήρια αυτή την στιγμή. Μου κάνει εντύπωση ότι το kraken πουλάει πλέον ακριβότερα από τα υπόλοιπα. Οχι φυσικά από το bitifinex που αυτό είναι ειδική περίπτωση. Μπορεί αυτό το pump να προέρχεται και από την επίσημη πλέον είδηση για επανεξέταση από τον sec της απόφασης για το ETF.

And for sure bitcoin will not be good to buy your coffee. If you want this then you choose a wrong payment system.
so you went with the "buy coffee" reddit script (facepalm) give this facepalm to your beloved boy Roger Ver. He claims that bitcoin is an everyday coffee payment system. I personal see bitcoin as it is. A decentralised payment system to store value and to transfer value around the world without the needing of the banking system. |

the great opportunity for bitcoin to hafve a huge innovation. this are doing this proposal. In other hand bitcoin works fine as it is now and nothing will happen if never scale imo.
Is still very cheap to transfer a huge stake of bitcoin around the world. Even if the price double the fees will be only 1-2$, very cheap for someone that want to transfer some thousand of dollars or for someone to keep his anonymity.
And for sure bitcoin will not be good to buy your coffee. If you want this then you choose a wrong payment system.
