My lightning transfers take 1 second and cost less than 1 penny.
How can the cost of the transfer be less than the cost of the energy it is claimed it uses? I could never figure thst out.
Off-chain transactions (like lightning, or from one exchange account to another at the same exchange, or from one account to another at the Salvadorean "wallet") can of course be quick and cheap, like any centralised banking.
There are two wallets that are using newer tech to make cheap + fast transactions happen (while still being decentralized + secure):
- Argent - Uses zkSync which is an L2 that compresses transactions and writes them to Ethereum - costs about 25c per transaction right now.
- Dharma - Uses Polygon which is it's own chain that posts a hash of everything that happened to Ethereum at regular intervals - costs < 1c per transaction right now .
USDC would make for a suitable candidate but of course, it's got $25 transaction fees on ETH. USDC-SPL maybe. The last time I tried to move some USDC-ETH, it was cheaper and more convenient to just have FTX wire me the money ($0) then wire it from my bank account to the recipient ($0).
In reality though, a CBDC is probably the best way forward.
If you're truly interested in a decentralized currency there are other projects focused on that.
There really is a place for a decentralized currency to replace paypal, but none of the cryptos live up to it. In fact I just tried using crypto again a few days ago and it was a terrible experience just like it was 10 years ago. My bitcoin transaction took over 30 minutes to verify so I tried changing to ethereum, and the transaction fee there is $8...
