Assunto: Re: [unSYSTEM] Proof of Burn ==> Trusted Identities
Proof of burn identities will be graduated (and optional)

   - Gradient proof of burn identities (PoB-IDs)
      - The purpose of a PoB is to:
         1. Associate a cost with creating an ID *that people are willing
         to trade with*, in order to create a financial disincentive for
         Sybil attacks
         2. Signal the level of risk associated with an individual trade
      - On point #2, if you are trading goods not valued higher than say
      $100, purchasing a PoB identity of $10 signals lower risk than
trading with
      an identity purchased with $0.2.
      - It is reasonable to assume that poor people will not be trading
      multi-million dollar yachts on OpenBazaar and would not need to purchase
      (or ascribe) a high valued PoB identity.
      - So poor people can purchase a relatively low cost identity if they
      wish
      - Please note, this is not the only way counter party risk will be
      signaled, it will be one of many factors to consider
   - Proof of burn identities are optional (at this stage of discussion by
   the devs)
   - If you choose not to purchase a PoB identity, then you will need to
      develop your reputation through the bitcoin-otc style web of trust that
      will be used to manage reputations and ratings (some discussion ongoing
      about integrating a PoW/PoB with making a rating)
      - Without a PoB-ID, it will take longer to establish a good
      reputation that people will be willing to trade with... but
essentially if
      they see than the identity has no PoB value ascribed to it, but
has a high
      trust rating across a broad network other well-regarded identities, your
      trade risk may be regarded as equivalent to a PoB-ID (maybe even better)
      - Also, without a PoB-ID, the trade you make with a buyer/seller may
      have more contractual safeguards in place (i.e. surety bonds, closely
      monitored trade by an arbiter, other stuff we or the market
hasn't thought
      of yet)
      - Even if people can create hundreds of identities for free, without
      a good web of trust reputation and a PoB-ID, it is unlikely that people
      will trade goods above a certain value.
