    This is super specific to an obscure blockchain. I feel like OP should provide a Conflict of Interest statement.

    Ok, I've read about this before but can someone with big brain dispute this? Seems like a solution to quite a problem but as it's crypto, not entire truth could be told here

    Why should routing nodes be rewarded at all.

    Solving Sybils for any blockchain is kinda something rational, ethical cryptographers wouldn't want to do... but I'm sure you can pay someone to claim they've solved it.

    I'm kinda okay with blockchains always remaining vulnerable and becoming relics of the past. It's all a scam. Not patching it.

    I asked GPT-4 if they could "summarize for idiots". I do not have enough knowledge to say if they summarized it accurately, but for anyone like me, who felt like a very big dummy while reading this, here's the summary:

    The essay discusses a method to prevent Sybil attacks, where a single adversary controls multiple nodes on a network to subvert the network's functionality, in blockchain networks by making it unprofitable for malicious nodes to add unnecessary 'hops' in transaction paths. Saito's mechanism rewards nodes for efficiently routing transactions to block producers, thus making Sybil attacks less lucrative. This is further illustrated with mathematical proof and examples comparing honest and Sybil behaviors, highlighting how the expected rewards change in both scenarios .
