$1 BILLION dollar cyber-heist

Hackers managed to infiltrate the Central Bank of Bangladesh. They were able to do this, because the central bank had no firewall (!) and had used a second hand $10 router to connect the banks systems to the SWIFT network (!!). The hackers then managed to move $100 million by sending a valid SWIFT t...

Re: So what does everyone think of Whats app's Instant billion people onboarded into encryption?

Yeah interesting, I tend to use the word privacy instead of anonymity or secrecy because people tend to be a lot more positive about that world. If I say secrecy or anonymous communication people freak out and say oooh oh that sounds dodgy. Wierd. Anonymity in my book is secrecy regarding the ident...

Re: So what does everyone think of Whats app's Instant billion people onboarded into encryption?

I think it is a fantastic step in the right direction. Recently, I had a great discussion about privacy vs secrecy. Privacy is the right that people have to communications that are not eavesdropped upon by third parties. Secrecy is the ability to protect your communications from eavesdropping by thi...

Good advice. I need to look at my cold storage situation. I'm a bit old school using paper wallets but will be getting a Ledger or Trezor asap There's nothing wrong with paper wallets. Just be mindful what they protect you from, and what they do not protect you from. I won't pretend to write a comp...

Playing with the raw bitcoin protocol

I'm having a blast programming a tiny little node that connects to the bitcoin network, using nothing other than sockets. I'm not using any RPC calls, or libraries, I am following the bitcoin peer to peer protocol language. Why? To learn, because it is fun, and because I can. It's of course not a fu...

Same thing happened to me.

Re: ShapeShift.io Hacked, Loses Unspecified Portion of Hot Wallet Funds, Taken Offline

Fortunately, funds are not held at ShapeShift in a custodial manner. Of course, when the transaction is processing, your funds are temporarily "in their custody", but only for as long as the funding transaction is sent and a payment transaction is not yet sent. This is a very small timeframe as comp...

Agreed. It has been stated many many times on this forum - you cannot profitably mine bitcoins using a regular PC. Anyone that tries to sell you that, is a scammer.

Storing unconfirmed transactions on disk

Re: Are you more upset by the Censorship, or the slowness of scaling progress?

I think censorship is leading to all sorts of problems, including misinformation about scaling being adopted by many people.

If there is an open and honest dialogue, and the vast majority of people are still against scaling - I have no right to force my opinion on them.

Business idea for someone in the USA

It would be a fun idea if we could do the following: 1. I order at Purse.IO, and have it shipped to your address. 2. You check the package, (completeness, status) and confirm receipt. 3. In the event of multiple packages, you repack into one package, optimizing for shipping. 4. Forward international...

DNB is most likely using this to study the merits of the blockchain.

Re: [2016-03-22] New Bitfury Data Shows That Over Half of Classic Nodes Come from Amazon / Choopa, Not Dedicated Servers

This is not surprising in the slightest. Classic nodes get DDoSed all the time. So they migrate to places where DDoS is ineffective: AWS datacenters and similar. In fact, nodes hosted in professional datacenters are arguably more valuable to the ecosystem as they have better resources at their dispo...
