The topic of BRICS and dethroning the USD as a reserve currency is not discussed much here because the sources reporting such things are generally scoffed at. Yet it makes sense that to obtain alternative views one has to include alternative sources.
There is a BRICS summit meeting later in August. Saudi Arabia, Indonesia, UAE, and Egypt are reportedly going to join BRICS. Also mentioned are Argentina and Mexico.
One article anticipated that the upcoming summit would also take steps to rollout the long discussed alternate currency. It's kinda like nuclear fusion... it's always been talked about but always X years away. However there are new motivators such as the US weaponizing the dollar against Russia (unilaterally seized Russia's offshore dollar reserves) as punishment for invading Ukraine which has other countries now understanding the same could happen to their assets. Another is growing tensions between the US and China. Yet another is the growing realization that the US is going to print trillions more dollars for the forecasted future which makes the dollars their dollars worth less each time the supply multiplies.
The new currency is expected to be based on a basket of commodities. The countries interested in joining alternative currency arrangements generally all produce most of the worlds commodities. While people scoff at BRICS, China's Belt and Road Initiative, Shanghai Cooperation Organization, etc, those countries produce the materials consumed by first world countries. Meanwhile the "developed" economies consume vs. produce anything of real value.
