Alena Vorobiova hadn’t concept a lot about bitcoin ahead of Russia invaded Ukraine in February. Rapid ahead to frame closures and shelling on her place of origin, money shortages at ATMs around the nation, and the central financial institution postponing digital money transfers — and he or she determined to present bitcoin a take a look at.
While cash suppliers continuously fee switch charges of 10% or extra while you ship $100 from the U.S. to Ukraine, bitcoin’s Lightning Community, which is a bills platform constructed on bitcoin’s base layer, slashes the price of transactions to just about 0.
Vorobiova and CNBC determined to place Lightning bills to the take a look at — with the experience and translation talents of bitcoin developer Gleb Naumenko, who’s these days hiding out within the western a part of Ukraine because the battle rages on.
The base line? It in reality does paintings in addition to bitcoin boosters say it does.
The method of downloading a crypto pockets onto Vorobiova’s telephone, shifting bitcoin over the Lightning Community from the U.S. to Poland, and retreating the similar in Polish foreign money from a bitcoin ATM from the southwest town of Wrocław took lower than 3 mins.

Sending sats from Dallas to Miami to Poland
Remaining August on a highway commute from Houston to Dallas, Peter McCormack — founder and host of the preferred What Bitcoin Did’ podcast — taught CNBC methods to use the Lightning Community to make rapid bills to someone on the planet.
The academic took lower than 60 seconds and concerned 4 elementary steps: We downloaded the Blue Pockets app and generated a one-time bill within the type of a QR code. McCormack scanned that QR code the usage of a equivalent app on his personal telephone, after which transferred 100,000 satoshis, or sats (the smallest denomination of bitcoin, about 0.00000001 BTC) from his account to ours. The entire switch used to be similar to about $50.
8 months later, from a resort room in Miami at the sidelines of the Bitcoin 2022 convention, CNBC determined to pay that wisdom — and a few of the ones sats — ahead.
On a three-way video name with Naumenko in Western Ukraine, Vorobiova in Southwest Poland, and CNBC in Miami, we adopted an overly equivalent collection of occasions.
With the steering of Naumenko, Vorobiova downloaded the Muun pockets app, a special form of self-custodial pockets for bitcoin and Lightning, made a four-digit pin, and generated an bill as a QR code. CNBC then captured that QR code the usage of the scan mode within the Blue Pockets and transferred over 50,000 of sats from McCormack. The charges amounted to fractions of a penny. (For functions of the experiment, Naumenko transferred any other 50,000 since the bitcoin ATM had a minimal withdrawal quantity.)
Bitcoin developer Jeff Czyz tells CNBC that Lightning wallets have compatibility as a result of all of them must put in force the Foundation of Lightning Generation, or BOLT, specification, which defines a layer-2 protocol for sending bills around the Lightning Community.
“A Lightning pockets app is comparable to a financial institution, in that sending cash between banks calls for them to talk the similar language,” stated Czyz, a developer with Jack Dorsey’s workforce referred to as Spiral (previously Sq. Crypto). That not unusual language is the BOLT specification.
“The Lightning Community is composed of nodes attached through fee channels, which can be used to ahead bills around the community with out the wish to agree with intermediaries,” persisted Czyz.

Identical to the educational within the automobile, the method of shifting sats from Miami to Wrocław additionally took a couple of minute.
From there, Vorobiova — who adopted her sister and niece to the Polish town of Wrocław to assist them get settled — went to some of the fifteen bitcoin ATMs in Wrocław and asked a withdrawal.
She achieved this through the usage of a QR code that the ATM spit out. She scanned the QR code into her telephone the usage of the Muun app, transferred her bitcoin into the ATM’s account, and the ATM in flip issued the cash. She ended up with 170 zloty, the Polish foreign money, value about 100,000 sats or $40. The ATM corporate took a charge of 10 zloty, or about 5.5% of the overall transaction.
“That is the identical waft as creating a fee for a just right or carrier the usage of Lightning,” defined Czyz.
For Vorobiova, this used to be extra of a a laugh experiment. She is in a position to cross backward and forward from Ukraine to Poland, and he or she tells CNBC that she is following the steering of Ukrainian regulators to simply use bank cards in the interim.
However the procedure illustrates how refugees with out a money and no approach of gaining access to their assets can use crypto wallets for banking.
Some Ukrainians use it to facilitate peer-to-peer transactions, whilst others have discovered that Lightning is an affordable and rapid solution to obtain donations and remittances from anyplace on the planet. In Poland, as an example, there are greater than 175 bitcoin ATMs, permitting refugees who fled with bitcoin to money it again out for fiat foreign money.
“Me sitting in California, I will nonetheless ship you any sum of money right away on your telephone anytime,” stated Gladstein.
“We do not have to fret in regards to the truth that you are a refugee. It isn’t important that you just do not have a Polish passport or a checking account. None of these items subject,” persisted Gladstein.
