Stellar Dolphin is presenting itself as an upcoming hard fork of Stellar Lumens (XLM). Hard forks often occur as an update to an existing blockchain. Projects will give everyone quite a lot of warning before such a hard fork occurs.
Stellar has made no comment on Dolphin, meaning that Dolphin is certainly not a majority-based hard fork. However, Stellar and many other cryptocurrencies are open-source and can be hard forked at any time by a minority of users. Stellar is a young cryptocurrency, but we only need to look to Bitcoin to see how hard forks can play out: Bitcoin Cash was a hard fork that had support from only a minority of miners.
Meanwhile, other hard forks, such as Bitcoin White, have turned out to be scams, and some, like Bitcoin Gold, merely failed. Suggested Reading: For more information on hard forks, check out our comprehensive ‘What is Blockchain‘ guide. Dolphin is planning to execute its dubious hard fork (and airdrop its tokens) on August 30th, but projects with minimal reputations often push deadlines into the indefinite future.
How it works
Fundamentally, Stellar is a system for tracking ownership. It uses an accounting ledger, shared across a network of independent computers, to store two important things for every account holder: what they own (their account balances) and what they want to do with what they own (operations on those balances, like buy or sell offers1.)The Stellar ledger is more robust than other blockchains'. Bitcoin, for example, stores only balances. Adding operations to the ledger means that when users' offers overlap (say, a buy and a sell) the trade can execute automatically.
The computers that run Stellar and publish the ledger are called nodes. They systematically validate the ledger’s contents so it’s always consistent across the network. For example, when you send someone a dollar on a Stellar-built app, the nodes check that the correct balances were debited and credited, and each node makes sure every other node sees and agrees to the transaction.
No one controls the Stellar network; by design, it stays in sync of its own accord2. The current Stellar network is hosted by hundreds of independent computers across the globe. This is different than how accounting works at a bank, say, where a single corporation unilaterally decides what happens.
Stellar has been running for four years and has handled over 450 million operations by over 4 million individual accounts.
Transactions cost roughly 1/millionth of a dollar.
Why is Stellar better than what exists?
The modern money system has evolved over hundreds of years and has picked up a lot of baggage along the way. Rent-seeking middlemen. Cumbersome currency controls. Outdated record keeping. Opaque rules. Siloed transactions.
For example, nearly every international wire is handled by something called the correspondent banking system. Very few banks can interact directly, so your money has to pass from bank to bank like a rumor until it finds a way to its final destination. In many places, the stepwise transfers still take place by hand. In all cases, it’s slow and expensive.
Stellar was designed from scratch to solve problems like this.
Stellar is a global, rather than a national, payment system. So users can transcend their local economy and interact directly with the world market. On Stellar, a person’s limits aren’t defined by borders—anyone on earth can own, hold, and send dollars, or euros, or yen, for example.
Stellar is a network of peers. It lets any user talk (transact) with any other user. So, for example, banks can work directly with one another, rather than “corresponding” through middlemen.
Stellar is ownerless and belongs to everyone. No one organization controls the network, so no one can shut it off, monopolize its functionality, or hoard its data.
Stellar handles any asset. Unlike many distributed systems, Stellar is currency agnostic. In fact, Stellar’s most important feature is that tethering a token to a traditional asset like a dollar is easy. So Stellar can support all the currencies that the world cares about, not just crypto.
Stellar is cheap. In fact, transactions are nearly free. Low fees mean more benefit for Stellar’s users. And Stellar’s low cost opens up use cases, like micropayments, that aren’t feasible with other systems.
Apps built on Stellar give users access to a borderless, frictionless marketplace; many of Stellar’s advantages can be understood in a single example currency transfer.
Putting it all together
Let’s imagine that Laura, in Mexico, wants to send 500 pesos to Victor, in Brazil. She wants him to receive the money as US dollars.
From the users’ perspective:
Laura creates a 500 MEX payment in her wallet app. She enters Victor’s payment address, specifies that he should receive dollars, and hits send. Five seconds later, he has 26.06 dollars in his wallet. The transaction cost Laura $0.000001.
Victor has immediate access to his digital dollars. He can hold onto them, trade them, send them to someone else, or convert them into Brazilian reals if he wants to spend them locally. The entire experience for both users happens within the wallet, as if it were a typical personal banking app.
From the app’s perspective:
Once Laura indicates her desire to send 500 pesos as dollars to Victor, her wallet app looks3 to Stellar’s built-in exchange, to the order books for Mexican pesos. Stellar finds the best offer, or sequence of offers, for turning Laura’s money into dollars.Stellar apps use the Horizon API to interact with the network. There are many high-quality SDKs for quickly building on Horizon.
Most often a currency conversion happens directly: Stellar finds someone else looking to go the other way, USD into MEX, and the trade is executed automatically.
Sometimes, a better price is available indirectly. Stellar always finds the best path. If say:
500 MEX → 202.1 XLM → 26.06 USD
were available, Stellar would prefer this to a direct MEX USD trade yielding 26.06 USD. Pathfinding happens seamlessly, and, no matter the path, the trade closes in five seconds.
For Victor, having USD might be a way to protect himself against fluctuations in the Brazilian real. Or to make his own cross-border payments. Because Stellar is a supranational network, he is able to own the dollars without being a U.S. citizen.
When he decides to withdraw his dollars into reals, his app will use Stellar’s pathfinding to convert the USD to BRL. Victor can then move the money into his Brazilian bank account from within the app—Stellar’s backend supports network-to-bank transfers.
