Alena Vorobiova hadn’t thought a lot about bitcoin earlier than Russia invaded Ukraine in February. Quick ahead to frame closures and shelling on her hometown, money shortages at ATMs throughout the nation, and the central financial institution suspending digital money transfers — and he or she determined to offer bitcoin a attempt.
Whereas cash suppliers typically cost switch charges of 10% or extra while you ship $100 from the US to Ukraine, bitcoin’s Lightning Community, which is a funds platform constructed on bitcoin’s base layer, slashes the price of transactions to nearly zero.
Vorobiova and CNBC determined to place Lightning funds to the check — with the experience and translation abilities of bitcoin developer Gleb Naumenko, who’s at the moment hiding out within the western a part of Ukraine because the battle rages on.
The underside line? It actually does work in addition to bitcoin boosters say it does.

Sending sat from Dallas to Miami to Poland
Final August on a street journey from Houston to Dallas, Peter McCormack — founder and host of the favored What Bitcoin Did’ podcast — taught CNBC the way to use the Lightning Community to make on the spot funds to anybody on the planet.
The tutorial took lower than 60 seconds and concerned 4 primary 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 utilizing an identical app on his personal cellphone, after which transferred 100,000 satoshis, or sats (the smallest denomination of bitcoin, about 0.00000001 BTC) from his account to ours. The whole switch was equal to about $50.
Eight months later, from a resort room in Miami on the sidelines of the Bitcoin 2022 convention, CNBC determined to pay that information — and a few of these sats — ahead.
On a three-way video name with Naumenko in Western Ukraine, Vorobiova in Southwest Poland, and CNBC in Miami, we adopted a really related sequence of occasions.
With the steering of Naumenko, Vorobiova downloaded the Muun pockets app, a special sort 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 utilizing 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 one other 50,000 as a result of the bitcoin ATM had a minimal withdrawal quantity.)
Bitcoin developer Jeff Czyz tells CNBC that Lightning wallets are appropriate as a result of all of them need to implement the Foundation of Lightning Know-how, or BOLT, specification, which defines a layer-2 protocol for sending funds throughout the Lightning Community.
“A Lightning pockets app is akin to a financial institution, in that sending cash between banks requires them to talk the identical language,” stated Czyz, a developer with Jack Dorsey’s crew often called Spiral (previously Sq. Crypto). That widespread language is the BOLT specification.
“The Lightning Community consists of nodes linked by cost channels, that are used to ahead funds throughout the community with out the necessity to belief intermediaries,” continued Czyz.

From there, Vorobiova — who adopted her sister and niece to the Polish metropolis of Wrocław to assist them get settled — went to one of many fifteen bitcoin ATMs in Wrocław and requested a withdrawal.
She completed this by utilizing a QR code that the ATM spit out. She scanned the QR code into her cellphone utilizing 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, price about 100,000 sats or $40. The ATM firm took a charge of 10 zloty, or about 5.5% of the whole transaction.
“That is the identical move as making a cost for a very good or service utilizing Lightning,” defined Czyz.

However the course of illustrates how refugees with no money and no method of accessing their belongings can use crypto wallets for banking.
Some Ukrainians use it to facilitate peer-to-peer transactions, whereas others have discovered that Lightning is an inexpensive and quick technique to obtain donations and remittances from anyplace on the planet.
