But as web speed evangelist Steve Souders has explained, that kind of blocking script tag is a "Frontend Single Point of Failure": if a server or network problem makes that script unavailable, it could prevent the whole rest of the page from appearing. That's why modern best practices emphasize loading most resources asynchronously.

to the <ins>
instead, for example.Watch Only - Watch Only addresses allow you to view transactions at an address without storing the private key in your wallet.
