One way is that it could help create a new economy for Palestine, one that isn't controlled by Israel or any other outside force. Blockchain is decentralized and operates on a peer-to-peer basis, which means that there's no central authority that can control or manipulate it. This could be a huge advantage for Palestine since they wouldn't have to rely on Israel or other countries for their economy to function.
Another way is that it could help to create a new currency for Palestine. Right now, they don't have their own currency and have to rely on other countries currencies. But with blockchain, they could create a digital currency that's specific to Palestine and that people there could use to buy and sell goods and services. This would give them more control over their economy and make it easier for them to trade with other countries.
I recently read about project ideas that help support the Palestinian people by providing crypto aid or by issuing NFT products. The main problem remains with the party that will organize the process and receive this aid and distribute it to those who deserve it. The idea is currently being implemented by the UNHCR to help Ukrainians in conflict areas, to help them with housing, heating and supplies expenses.
