Selected Bitcoin Coders, Consultants for Hire in Ukraine

What is Bitcoin (hereinafter BTC)? It is the most popular e-currency. So-called “virtual” money that is not subject to inflation and takes the increase in the modern world. Japan is the first country in the whole world where the cryptocurrency is recognized as the official payment tool. BTC relies on cryptographic principles with the aim to create unique, non-reproducible and divisible currency. Users store cryptographic keys to their own money locally on a personal computer, and conduct transactions directly with each other through a peer network, verifying through the network the authenticity of remittances. Each coin in the system has its own unique key. Executing the transaction, users add the public key to the coin and sign it with his personal private key. To prevent a double coin being debited, all transactions are broadcast to other participants. BTC is based on the recording of cash flows using asymmetric encryption. In other words, it means that for each new transaction, the keys are checked against the list of previous transactions. It is necessary to know that currency rate of BTC is variable and depends on many factors. The information is presented in the form of a table showing BTC buying and selling rates on the most popular crypto exchanges.

Are there any Java libraries to work with Bitcoin?

“The BCCAPI (BitCoin Client API) allows you to create a light-weight secure Bitcoin client in Java. BitCoinJ also uses the Bouncy Castle encryption algorithm implementations.
