While it is great to have a review over the field, one wonders why the largest and most advanced genomics blockchain platform HLTH.network (previously Shivom) was not covered at all, and why only 'old' blockchain systems were discussed, leaving state-of-the-art blockchains out of consideration (e.g. Solana, Avalanche), that solve the issues facing the first two blockchain 'generations' like Bitcoin and Ethereum, with newer chains scaling better, being much faster, cheaper, and do not require so much energy by several factors.
