Scalability The core Bitcoin network can scale to much higher transaction rates than are seen today, assuming that nodes in the network are primarily running on high end servers rather than desktops. Bitcoin was designed to support lightweight clients that only process small parts of the block chain (see simplified payment verification below for more details on this). A configuration in which the vast majority of users sync lightweight clients to more powerful backbone nodes is capable of scaling to millions of users and tens of thousands of transactions per second. Scalability targets VISA handles on average around 2,000 transactions per second (tps), so call it a daily peak rate of 4,000 tps. PayPal, in contrast, handles around 4 million transactions per day for an average of 46 tps or a probably peak rate of 100 tps. Let's take 4,000 tps as starting goal. Current bottlenecks Today the Bitcoin network is restricted to a sustained rate of 7 tps by some artificial limits. The protocol has two parts.

P2sh_safe_address This paper describes a mechanism for using Bitcoin’s P2SH functionality to build a stronger, more secure web wallet. Background Bitcoin addresses (where your bitcoins are stored) are secured today using public key cryptography and the Elliptic Curve Digital Signature Algorithm (ECDSA). Client-side wallets The advantage of a client side wallet is that your bitcoin keys are entirely your own. Web Wallets Web Wallets have the advantage that they are accessible through the web, from anywhere. But the disadvantages are obvious. Pay To Script Hash (a.k.a. P2SH is a new type of bitcoin address which was introduced as part of Bitcoin Improvement Proposal 16 (BIP 16) in early 2012.

xCoinMoney online wallet for Dollars, Bitcoin and Litecoin Coinbase's Fred Ehrsam Drops Knowledge on Paul Krugman 'Virtual' Currencies Draw State Scrutiny By ROBIN SIDEL and ANDREW R. JOHNSON State banking regulators are scrutinizing companies that let people buy and sell virtual currencies such as bitcoin, and some are looking at requiring costly licenses, according to people familiar with the efforts. It is the latest sign that the freewheeling world of virtual currencies is about to get less free. George Frey/Getty Images Bitcoin enthusiasts say the currency derives its value from its limited supply and the support of the people using it. "Virtual" currencies can be used just like dollars among people who agree to accept them. In the past three months, the Treasury Department, prosecutors and now state regulators have taken aim at virtual-currency exchanges, telling them they must follow traditional rules aimed at thwarting money-laundering. Companies using virtual currencies said they welcome the regulatory push because it helps legitimize the practice and build trust with users and investors. "This is definitely on our radar. Mt. Mr.
