To purchase or sell products with Bitcoin, you must be able to transmit funds from a particular location, similar to how you would exchange mail from a mailbox. However, we’re talking about Bitcoins and not postcards. The place where you transmit Bitcoins is over the internet.
Understanding Bitcoin Addresses
Bitcoin addresses are nothing more than a string of numbers and letters representing a network location. There are many different types of addresses in Bitcoin, and they all work the same by pointing to the location where the Bitcoins should be sent.
Bitcoin addresses get used when you want to receive bitcoin. They are supposed to be utilised only once, unlike our real-world addresses. The concept is that receivers will create a unique, one-time address for each Bitcoin transaction and provide it to senders. Instead of thinking of addresses as a place to store Bitcoin, think of it as a way to guide your transaction.
Cindy has a Bitcoin wallet application installed on her tablet, so I’d like to give her some Bitcoin. Cindy creates a new, exclusive address with her Bitcoin wallet app and sends it to me. Now I can safely transfer the bitcoins over to Cindy.
Almost all Bitcoin wallets include this feature. Bear in mind that it’s just for this occasion as a Bitcoin address is for one-time use only. Cindy will feel safe sharing her newly created Bitcoin address because it doesn’t contain any confidential information provided you create a new address for each transaction.
When prompted during the sending process, I simply input Cindy’s new, one-time address into my Bitcoin wallet. It’s worth copying and pasting addresses because you cannot reverse transactions. That’s it; your transaction is sent for confirmation, and the address’s life cycle has come to an end.
Returning to Sender
One unusual characteristic of Bitcoin is that it does not keep track of where transactions originate. Bitcoin transfers, unlike standard letters, do not require return addresses. The last address to which you sent Bitcoin is the nearest thing to a return address in Bitcoin. However, this does not always indicate the correct individual.
Satoshi Nakamoto made this design decision to protect Bitcoin users’ privacy by eliminating the possibility of connecting transactions. Let’s go back to the above example for clarification. I remember I sent Cindy too much of my Bitcoin a week after the initial transaction. She owes me Bitcoin now.
Cindy would be relying on a dangerous assumption if she returned my Bitcoin to the address I sent it from before, assuming it would transfer back into my personal wallet. Cindy would also be relying on the dangerous assumption that I’m still utilising that same Bitcoin address. I might have misplaced or had my phone stolen, and then the previous Bitcoin address belongs to the thief, not to me.
This is why each transaction needs a new Bitcoin address; it avoids risky assumptions and prevents you from losing Bitcoin in cyberspace. The intelligent thing to do is build a one-of-a-kind Bitcoin address for every occasion, send one to Cindy for one-time usage, and never use it again.
Getting Bitcoin Addresses
To obtain a Bitcoin address, you must first obtain a Bitcoin wallet, which is software that enables you to store, receive, and send Bitcoin funds securely on the Bitcoin network.
Your private key, which is your Bitcoin password, is also stored in your Bitcoin wallet. There are four types of Bitcoin wallets. You can choose mobile, web-based, desktop and hardware.
Is Bitcoin Anonymous?
Bitcoin’s anonymity isn’t great. It’s pseudonymous as every user has a public address that could be linked to an IP address or exchange account and, thus, to a real identity through practical network analysis.
What Is the Extent of Bitcoin’s Anonymity?
It’s anonymised in the context that every Bitcoin element, including addresses, transactions, and public and private keys, are viewed as text strings that have no direct connection to anybody’s identity. If you use an address on a website that meets Know Your Customer rules, it can be connected to a true identity.
Early on, there was a lack of awareness about blockchain technology. Since Bitcoin is untraceable and anonymous, many people assumed it was a refuge for criminals and terrorists. When blockchain technology grew in popularity, it became clear that Bitcoin’s public ledger was a gold mine of data for authorities. Any bitcoin transaction gets recorded in an unchangeable database forever.
On the blockchain, all bitcoin transactions are made public. Since all bitcoin transactions are permanent and public, a map is built over time, allowing simple analytical tools to paint an image of where bitcoins are headed. Bitcoin addresses are anonymous, but they provide little anonymity if linked to a real-world identity.
There are various ways to link addresses to true identities, the most common of which are exchanges’ Anti-Money Laundering regulations, Know Your Customer policies and blockchain research.
How to Make Bitcoin Transactions More Private
There are some privacy-enhancing methods available to Bitcoin users, but they aren’t all flawless.
Build a Full Node
A wallet linked to a Bitcoin node is needed for everyone to transact on the blockchain. Nodes validate transactions and blockchain blocks. You depend on someone else’s node to send your transactions through the blockchain if you aren’t running a full node.
Assume you’re using a ledger wallet. To send and receive your transactions, you depend on the ledger. Ledgers say that your name is not linked to the device’s serial number, and none of your information gets collected during setup. However, they could connect the IP address directly to your device, putting your privacy at risk.
A VPN encrypts traffic and hides IP addresses while it’s running correctly. This ensures that the ISP and collaborators are unable to see which websites are visited. It also implies that the websites you visit are unaware of your location or IP address. You can use a VPN to link to Bitcoin clients and prevent passers-by from mistaking you for the node’s owner.
Use Lightning Network
Unlike Bitcoin, each node doesn’t have to keep records of each transaction on the Lightning Network. Only transactions passing through them are clear to them. A node’s only history is with other nodes with whom it transacts, making trading bitcoins similar to holding an IOU amongst friends and paying it off in cash.
Only when opening and closing channels does the bitcoin blockchain come into play. Creating a channel is equivalent to keeping track of your friends’ activities. When a tab opens, data enters the blockchain. When you pay that tab, all transactions between when you open and close the tab don’t get stored on the bitcoin blockchain, and only involved parties know about them.
Although Bitcoin is not completely anonymous, it still keeps your information private and safe. There are also ways that you can keep some of your information hidden, as we shared above. Bitcoin is still a safe and secure way to use, send and receive crypto-currency.
The blockchain is in nature very safe to operate on but using addresses takes some time to learn and can be difficult at first.
