Sabi sa balita, they used distributed ledger, it does not necessary means na blockchain tech. talaga ang ginamit nila though ang blockchain is one kind of distributed ledger. Possibly another form of distributed ledger ang gamit nila at hindi blockchain tech, na mixed up lang siguro nila or there is some misconception on the part nung speaker.
Pagdating naman sa mode of payment, wall naming sinabing tumatanggap sila ng cryptocurrency as payment kung Hindi the usual na online payment katulad ng sinabi mo.
An interesting article here describing about the difference ng blockchain tech at distributed ledger tech.
The most important difference to remember is that blockchain is just one type of distributed ledger. Although blockchain is a sequence of blocks, distributed ledgers do not require such a chain. Furthermore, distributed ledgers do not need proof of work and offer – theoretically – better scaling options.
Removing the intermediary party from the equation is what makes the concept of distributed ledger technology so appealing. Unlike blockchain, a distributed ledger does not necessarily need to have a data structure in blocks. A distributed ledger is merely a type of database spread across multiple sites, regions, or participants.
On the surface, distributed ledger sounds exactly how you probably envision a blockchain. However, all blockchains are distributed ledgers, but remember that not all distributed ledgers are blockchains. Whereas a blockchain represents a type of distributed ledger, it is also merely a subset of them.
