Dear authors, I read your draft and get interested in utilizing ALTO for block chain. I have considered about it over the past few days. Here are some comments:
1. Be more general-purpose for block chain I noticed that there’re some parts of introduction about bitcoin have been removed from the first version and believed this draft is not specified for bitcoin. Also mentioned in title, this draft is about block chain. But it only mentioned bitcoin as use case of block chain. In bitcoin wiki, it said “Block chains were invented specifically for the Bitcoin project but they can be applied anywhere a distributed consensus needs to be established in the presence of malicious or untrustworthy actors.” Despite it may cost too much to implement block chain for non-financial cases, mentioning some other use cases (e.g. alternative chain) could make the draft looks more general-purpose for block chain. 2. Consider about security Compare to traditional data base, I thought the block chain was invented to solve the security problem. So, it is necessary to consider about security which is much more important than efficiency. For example, ALTO server may accept some suboptimal results to improve the randomness and avoid the prediction mentioned in section 7. 3. Let applications aware of the different roles In section 6, it said “This requires that the ALTO server is aware of the different roles”. But roles like wallet, miner and relay nodes are specified for bitcoin, it may have different roles in other use cases of block chain. Including such information in ALTO protocol is not general-purpose for block chain. By the other hand, ALTO is invented to provide low-level network information which application can’t get before. Since the information about different roles is not low-level, it could be more appropriate for ALTO to let applications maintain the map relationship between each node and its role. Hope these helps. :) Best Regards, Shenshen Chen 2016-07-07 23:36 GMT+08:00 Stefan HOMMES <[email protected]>: > Dear ALTO group, > > > > I am a research associate from the University of Luxembourg, and we have > submitted a draft that is using ALTO for the blockchain: > > https://datatracker.ietf.org/doc/draft-hommes-alto-blockchain/ > > > > We are very curious and interested to receive some feedback about this > draft.
