I agree with you that most initial block at the blockchain is called Genesis block and to determine Genesis block we have to follow block explorer which is an option we see steemworld site when we open it and login to our account and then we have to command one and then we have to click on ok so that we may see information about Genesis block

I have also joined this platform few months ago around 10 to 11 months ago and from start of my journey I face the problem just like you to not show pictures and profiles of all users due to downtime of this block chain. I wish you success in your participation
