According to Wu, the Bitcoin payment protocol Spark experienced a service outage today, lasting about 4 hours, but it has now been restored. Blink Wallet previously announced that its Spark service for non-custodial accounts was temporarily unavailable, and the team was investigating the issue. Spark, developed by Lightspark, a company founded by former PayPal president David Marcus, is a Bitcoin Layer 2 payment protocol compatible with the Lightning Network and supports assets like stablecoins. Wallets such as Wallet of Satoshi and Blink have already integrated Spark. https://(wublock123.com)/news/lightspark-bitcoin-layer2-spark-outage-4-hours-67107
