Re: Bitcoin crash when sending coins

Re: Bitcoin Address Collisions

Re: Could the bitcoin network be destroyed by someone generating endless bitcoin add
When you generate a new bitcoin address, it only takes disk space on your own computer (like 500 bytes). It's like generating a new PGP private key, but less CPU intensive because it's ECC. The address space is effectively unlimited. It…

Re: Hostnames instead of IP Addresses
The current sending by IP is not very useful: it connects to the IP, so you'd like to use TOR for anonymity, but then it can totally be eavesdropped and man-in-the-middled. The future plan for sending to an IP is to make it a bitcoin…

Re: Privacy versus Safety: handling change

Re: Hypothetical question on lost coins / transfers

Re: Is safe running bitcoins with the same wallet on more computers simultaneously?
