Bitcoin is an innovative payment network and a new kind of money. As a new user, you can get started with Bitcoin without understanding the technical details. Once youve installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should be used only once. The blockchain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. It allows Bitcoin wallets to calculate their spendable balance so that new transactions can be verified thereby ensuring theyre actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography. A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast to the network and usually begin to be confirmed within 10-20 minutes, through a process called mining. Mining is a distributed consensus system that is used to confirm pending transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all the subsequent blocks.

It is never too late to be what you might have been.

We are a team of internet professionals of various specializations that range from ideation and product definition, to prototyping, development and performance profiling for high traffic. We use extreme programming techniques such as pair programming, collective code ownership, retrospectives and test driven development. Our process resembles a mixture of Kanban and Scrum, with short iterations, allowing us to stay lean = deliver maximum value at minimum cost. We believe in freedom at work, have a flat organization structure and no dedicated sales or project management staff. Everyone of us works directly on the code while also actively communicating with the client to minimize any information noise - the number one cause of failure.
