Too Long; Didn't Read
Last week I received a private invite to the beta launch of <a href="https://sparkswap.com">Sparkswap</a>, a semi-decentralized built on the Lightning Network. The only centralized part of the exchange is the “relayer,” which the Sparkswap team controls to perform certain functions like aggregating the orderbook with bids and asks. For the most part, however, the users (aka “brokers”) are in total control: they host nodes themselves, their own wallets with their private keys, conduct transactions directly with the counterparty, etc.
