Since it mimics the structure of an email, users have gravitated to it, and it has quickly gained adoption by many Lightning wallets. Lightning addresses are a welcomed addition to the address stack and a pretty valuable tool for making Lightning payments. What is a lightning address? A Lightning Address is an internet identifier for a wallet, but it looks like an email address. The Lightning Address protocol can be used by everyone to send money like they do messages with emails.
While the experience may feel similar to email, in the backend, it abstracts the use of LN-URL away from the user. Lightning addresses are a more straightforward way for anyone to send you Bitcoin instantly on the Lightning Network. Instead of having to use a QR code, creating a long string of text for an LN-URL or generating an invoice, the Lightning Adress can serve as a re-usable address to receive payments.

Newer "HD wallets" can generate a "seed" token which can be used to allow untrusted systems such as webservers to generate an unlimited number of addresses without the ability to spend the bitcoins received. Main article: Bitcoin transaction Record of the BTC transfer from one address to another generates a transaction. It contains the hash of the previous transaction signed by the sender and Bitcoins recipients address.
All information is sent to the Bitcoin network and after signatures verification transaction is accepted for processing. Most Bitcoin wallets have a function to "sign" a message, proving the entity receiving funds with an address has agreed to the message.
This can be used to, for example, finalise a contract in a cryptographically provable way prior to making payment for it. Some services will also piggy-back on this capability by dedicating a specific address for authentication only, in which case the address should never be used for actual Bitcoin transactions. When you login to or use their service, you will provide a signature proving you are the same person with the pre-negotiated address.
It is important to note that these signatures only prove one receives with an address. Since Bitcoin transactions do not have a "from" address, you cannot prove you are the sender of funds. Current standards for message signatures are only compatible with "version zero" bitcoin addresses that begin with the number 1.
Bitcoin Address Validation[ edit ] If you would like to validate a Bitcoin address in an application, it is advisable to use a method rather than to just check for string length, allowed characters, or that the address starts with a 1 or 3. Validation may also be done using open source code available in various languages or with an online validating tool.
Multi-signature Bitcoin address[ edit ] Multi-Signature Addresses Addresses can be created that require a combination of multiple private keys. Since these take advantage of newer features, they begin with the newer prefix of 3 instead of the older 1. These can be thought of as the equivalent of writing a check to two parties - "pay to the order of somebody AND somebody else" - where both parties must endorse the check in order to receive the funds. The actual requirement number of private keys needed, their corresponding public keys, etc.
Address balances[ edit ] Addresses are not wallets nor accounts, and do not carry balances. They only receive funds, and you do not send "from" an address at any time. Various confusing services and software display bitcoins received with an address, minus bitcoins sent in random unrelated transactions as an «address balance», but this number is not meaningful: it does not imply the recipient of the bitcoins sent to the address has spent them, nor that they still have the bitcoins received.
An example of bitcoin loss resulting from this misunderstanding is when people believed their address contained 3 BTC. They spent 0. The remaining 2. With one of the most reliable news teams in the industry, Bitcoinist provides up-to-date news and insightful analysis.
