A Brief History
It was believed that Bitcoin had been created by an unknown developer disguised as Satoshi Nakamoto in 2009. Because it is completely decentralized and does not have a regent, all transactions are processed directly between users. The total number of Bitcoins in circulation is capped at 21 million, aiming to create ‘limited scarcity’ that minimizes the possibility of inflation or manipulation. Some people then regard Bitcoin as ultimate storage value akin to digital gold. The whole software source code runs on proof-of-work blockchain technology, shared public ledger, and the transaction history consisting of “blocks” joined together in a “chain”,
Thus preventing alterations in Bitcoin transactions. It serves as a permanent record of every transaction. Transactions are validated by users on the Bitcoin network in a process called mining, which is programmed to see that the new transaction corresponds with all already completed unexecuted transactions. This makes it impossible for people to spend Bitcoins not yet owned, nor can they easily double-spend their coins.
BTC in practice
New coins are created as part of the Bitcoin mining process. Bitcoin rewards miners, who run computer systems that help secure the network and verify incoming transactions. These Bitcoin miners run full nodes and use specialized hardware called ASICs (Application Specific Integrated Circuit Chips) to find and create new blocks. As a series of computationally challenging problems are solved, completed “blocks” are added to an ever-growing “chain,” and this mining process can fluctuate, becoming easier or harder depending on demand and the value of the network.
This is called network difficulty. In addition to block rewards, miners also collect transaction fees, which further incentivize them to secure the network and validate transactions. This independent network of miners also reduces the chances of fraud or misinformation being recorded, as the majority of miners must verify the authenticity of each block of data before it is added to the blockchain. This process is called “proof of work.”
Sample Account System Using JSON-RPC Needed
I need someone to write some sample code (preferably in Python or Java) that shows the recommended way to create an account system using a JSON-RPC interface. Most websites that sell stuff require something like this. Anyone who’s been following the JSON-RPC thread here will probably have an idea of how this should work.
When a user logs into their account, they will see a Bitcoin address that they can send to to add funds. Check if it is used before displaying it, and if so, replace it with a new address (getnewaddress <username>). You just need to keep the most recent Bitcoin address of your account in your database. (I have posted an example code snippet somewhere before. Search for getnewaddress)
Use getreceivedbylabel <username> to get the “credit” amount of an account using the username as the label. You need to store a “debit” amount in your database. The current balance of the account is (Credit – Debit). When a user spends money, the debit increases.
If 0 or more confirmations are required, it would be a good idea to display both the current balance (0 confirmations) and the available balance (1 or more confirmations). You will then see immediate confirmation that your payment has been approved. Current and Available Double should be optional, as not all sites require waiting for verification. Most sites that sell digital products can safely allow 0 confirmations.
A nice sample app for this would be a simple bank site, which would have the above, plus the option to send a payment to a bitcoin address. The sample code should be the simplest possible with the minimum extra stuff to make it a working site.
