Dear Flare Community,
With Grin being enabled in the latest 1.0.4 update, it is important to note that sending/receiving Grin is a bit different from traditional cryptocurrencies. In a Mimblewimble blockchain, all transaction amounts and locations are hidden rendering a totally address-less blockchain. Because of this, addresses in Grin are not similar to traditional cryptocurrency types, and therefor using Grin is a bit different.
On initial startup:
When 1.0.4 is launched for the first time, and when Flare is restored/password is changed, Grin will take several minutes to initialize as it scans old transactions that may belong to your wallet. During this process, the entire Flare wallet is available to use while Grin is being set up.
Flare gives you two different address types to receive Grin with – Grinbox and Hedwig. A Grinbox address is similar looking to Bitcoin type addresses, while a Hedwig address is essentially http(s) address that reroutes your ip through a relay. Both of these methods conceal IP address for the user.
Flare enables three different address sending formats – Grinbox, Hedwig and http(s). When sending, Flare will detect which format you are using and send your transaction accordingly.
Grinbox vs. Hedwig Relay V1
Grinbox works as a middle-man mailbox system. When using Grinbox – unlike http/Hedwig transaction methods – both parties do not need to be online. Instead, the next time the receiver/sender is online, the system will route the necessary information to the user. Hedwig is similar to http(s) in the sense that both sender/receiver need to be online while making a transaction.
