What Is a Stealth Address?
A stealth address in cryptocurrency is a temporary, one-time wallet address that enhances transaction anonymity by serving as a proxy for your regular wallet address. Publicly available wallet addresses can be traced back to individuals, compromising privacy. Stealth addresses provide an additional layer of security, ensuring that your personal details remain private during transactions.
Understanding Stealth Addresses
A blockchain network is a distributed ledger similar to a shared database containing the recipient and sender’s address and the transaction amount. All network participants can view this information. This is not inherently bad, but an active observer with intent can trace transactions and possibly identify parties involved.
A standard cryptocurrency transaction needs two addresses—one from each party. The transaction does not include information about address owners because the network does not record it. This lack of this data is the crucial factor behind the anonymity that should be inherent to cryptocurrency.
However, transactions are pseudonymous. The identity protection features of blockchain technology are not 100% anonymous because transactions can be tracked to the addresses involved in them. If an address owner’s information is discovered, the address no longer provides anonymity.
As an example of the benefits of a stealth address, if you wish to raise funds for a charity in cryptocurrency, you may need to provide the public address to which cryptocurrency funds can be sent. This will associate your wallet address with your name, allowing others to track your transactions. They can also track where you send the funds you raise.
Fast Fact
Stealth addresses are a deceptive tactic, like using a post office box to hide your home address. They provide an extra layer of security for cryptocurrency users.
If you were to generate a stealth address for your charity-raising needs, you could have funds sent to that address without revealing your personal wallet address.
Unique Features of Stealth Addresses
In a typical cryptocurrency transaction, the sender uses the recipient’s wallet address to send funds. A wallet address is a public address that can be tracked. Peter Todd proposed stealth addresses in 2014 to deal with rising concerns over this ability.
When you use a stealth address, the blockchain records the transaction and enters the proxy address—this is what hides your public address. A stealth address can be created using different protocols or mechanisms within a cryptocurrency wallet if it supports it.
There are several different mechanisms for creating stealth addresses. For example, Monero uses ring signatures and RingCT—decoy output addresses and masked addresses—to make it difficult to trace the sender. This is a technique designed to confuse would-be trackers while using stealth addresses.
Potential Risks of Stealth Addresses
Considering the ability of stealth addresses to confuse trackers and boost anonymity for honest cryptocurrency users, they’re also an attractive option for users with dishonest or nefarious intentions.
Fast Fact
It’s important to note that most cryptocurrency users are honest ones. Chainalysis, a blockchain data analysis company, found that only 0.12% of cryptocurrency transactions were used for illicit activity in 2021 and .24% in 2022. By mid-2023, crypto crime was down $5.5 billion from 2022.
With that in mind, regulatory agencies, tax authorities, and governments are developing methods to discover dishonest cryptocurrency users. For example, both privacy coins and stealth addresses have been used to avoid taxes. The Internal Revenue Service (IRS) responded by initiating Operation Hidden Treasure, designed to crack down on tax evasion by cryptocurrency users.
The Department of Justice announced in October 2021 that it had created the National Cryptocurrency Enforcement Team, designed to investigate illegal activity funded by cryptocurrency.
How Do Monero Stealth Addresses Work?
Monero uses a three-tier system for privacy: ring transactions, stealth addresses, and RingCT, which act together to place your address behind another and confuse any would-be trackers.
What Is a Wallet Address?
Your wallet address is the publicly available string of numbers that act as an address for others to send cryptocurrency to.
What Does a Cryptocurrency Address Look Like?
Depending on the cryptocurrency you use, your address is a string of alphanumeric characters. For example, an address might look like 12dRugNcdxK39288NjcDV4GX7rMsKCGn6B.
The Bottom Line
Cryptocurrency stealth addresses are blockchain addresses that are different from your actual wallet address. The intent behind them is to attempt to provide or enhance the anonymity that blockchain is supposed to possess.
