Bitcoin is a decentralized P2P electronic cash system without a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of the 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 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.
Bitcoin is an electronic cash system that uses a peer-to-peer network to prevent double-spending. It's completely decentralized with no server or central authority.
What's New in This Release: [ read full changelog ]
Incompatible Changes:
· This release no longer maintains a full index of historical transaction ids by default, so looking up an arbitrary transaction using the getrawtransaction RPC call will not work. If you need that functionality, you must run once with -txindex=1 -reindex=1 to rebuild block-chain indices (see below for more details).
Improvements:
· Mac and Windows binaries are signed with certificates owned by the Bitcoin Foundation, to be compatible with the new security features in OSX 10.8 and Windows 8.
· LevelDB, a fast, open-source, non-relational database from Google, is now used to store transaction and block indices. LevelDB works much better on machines with slow I/O and is faster in general. Berkeley DB is now only used for the wallet.dat file (public and private wallet keys and transactions relevant to you).
· Implemented many optimizations to the way transactions are verified, so a running, synchronized node uses much less memory and does much less I/O. He also implemen...
