SatoshiPay IOTA Flash Channels – Demo


Satoshi Pay have revealed stage two of their collaboration with IOTA, with the public release of the proof-of-concept demo site.

Flash Channels

Flash channels provide a way to transact for free in high frequency without computing PoW constantly. This reduces the transaction overhead to a negligible level by creating transactions off network. The resulting channels free up users to transact securely and instantly.

Pay on Demand for Content Providers

This combination reveals the potential of a nanopayment paywall system for content sites, newspapers, blogs, video sharing sites etc.

Channels are necessary, because cryptocurrency ledgers take some time to settle transactions. This can vary between a few seconds and a few hours, depending on the underlying ledger or cryptocurrency. In some situations instant or near-instant settlements are needed, and payment channels allow for this to happen by aggregating payments before they get settled on the ledger. The settlement of funds closes a channel.

Flash Channels are payment channels on IOTA’s tangle. SatoshiPay’s current production system was one of the first Bitcoin-based micropayment channel implementations on the web.
