Bitcoin is a decentralized electronic cash system that uses a peer-to-peer network to prevent double-spending.
Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending.
Bitcoins can be sent easily through the Internet, without having to trust middlemen and transactions are designed to be computationally prohibitive to reverse.
Bitcoin Portable helps you stay safe from instability caused by fractional reserve banking and central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by banks.
What's New in This Release:
· Check all transactions in blocks after the last checkpoint (0.5.0 and 0.5.1 skipped checking ECDSA signatures during initial blockchain download).
· Cease locking memory used by non-sensitive information (this caused a huge performance hit on some platforms, especially noticable during initial blockchain download).
· Fixed some address-handling deadlocks (client freezes).
· No longer accept inbound connections over the internet when Bitcoin is being used with Tor (identity leak).
· Re-enable SSL support for the JSON-RPC interface (it was unintentionally disabled for the 0.5.0 and 0.5.1 release Linux binaries).
· Use the correct base transaction fee of 0.0005 BTC for accepting transactions into mined blocks (since 0.4.0, it was incorrectly accepting 0.0001 BTC which was only meant to be relayed).
· Don't show "IP" for transactions which are not necessarily IP transactions.
· Add new DNS seeds
