    Technical Questions About the Discovery Protocol

    Posted: 22 Mar 2020 12:52 PM PDT

    Dear ETH Community,

    I am currently working on a semester project during my Master degree related to Ethereum. There are a couple of technical questions I am not sure being able to fully answer. Could some people please help me out?

    • How to find the ID (hash of the nodes public key) of a node running at a particular IP/Port?

    I know that through the discovery protocol DISCv4 and thus filling its own table one could scan the table for the wanted IP/Port and get the nodes ID (if it learns about it someday). Is there also a direct way? Like sending some message to this IP/Port and get back a response containing its ID. I know about discv4-dns-lists, what does this exactly list? All the nodes found by scanning the networks? Would it be possible to go through the ENR records, convert it in readable format, get the entry for the IP/Port and then, is the key for the JSON object the node ID? How does a node advertise its public key when joining the network? Somehow the nodes need to link IP/Port and ID.

    • Is the node ID (again the hash of the nodes public key) also the corresponding public key to some secret key for an account stored on this node?

    Is the node ID and the key pairs generated for the accounts on that node completely separated? If yes, what happens if a node loses the node key pair, thus cannot sign any update, and generates a new key pair? Every other node would not accept a new key pair (new ID) for that node, since the signature does not verify. I know about this post, is it still up-to-date? No relation whatsoever between account key pairs and node ID?

    • During the discover protocol, why is it wanted to find nodes as close as possible (xor between the node IDs)?

    Is that only to build the DHT of peers, and has no meaning in the upper Ethereum protocol? Is the closeness of any importance other than storing information about peers in the DHT?

    • Say a node has a table of peers. How does the node decide to which peers to connect to and to how many does it connect?

    The table can become quite big, I guess a node does not connect to all peers at once. How does a peer chose to which to connect to and exchange information like TXs, blocks, ...? Might it connect first to close peers like asked in the previous question? Does it maybe chose them randomly among the table? Does it connect to all of them?

    Thank you in advance for you time!

    Best regards,

    McJvck

    Web 2.0 on mesh-network short wave radio?

    Posted: 22 Mar 2020 10:13 AM PDT

    Hello all,

    I had a thought about censorship resistance, and if the US (or any government) moved to fully monitor-able digital currency.

    What if a fiat smart-coin could resist transference to a decentralized coin format(non transferable by design) My dad and I started talking about what would happen if the fiat-to-ethereum bridge were to be eliminated, distribution of ethereum would then be only, or mostly, in exchange for goods and services.

    Then out of left field I had a realization blast-off and saw Web 2.0 running on a mesh network via short wave radio. With some googling I have found that this IOT-esque web is being used in maritime industry.

    https://www.rivieramm.com/news-content-hub/news-content-hub/shortwave-mesh-network-delivers-secure-iot-connectivity-57130

    https://knlnetworks.com/

    So is there anyone in here who has the expertise to say whether this type of thing would be capable of supporting Web 2.0?

    Tl;dr: can ethereum network run via short wave radio with no direct contact to the internet?
