Editing Decentralized underwriting (section)

==== Components ====
# iDAO <math>=\{Underwriters\}=\{U_i\}=</math> ledger of all REP tokens
# <math>C(t)=</math> Capital reserves
# <math>\{active\  contracts\}=\{+ \ premia\} \cup \{-\  risk\ of\ potential\ claims\}</math>  

From [[Reputation tokenomics|REP tokenomics]], we have the following definitions:
#<math>R(t)=</math> the total number of REP tokens in the iDAO at time <math>t</math>.
# The rate of total premia <math>f'={df \over dt}</math> that the iDAO earns. Therefore <math>f(t)</math> denotes the '''total fees''' earned from the beginning of the iDAO until time <math>t</math>.
#<math>f_0^1 (t)</math> is the cumulative [[Reputation#REP salary mechanism|reputational salary]] collected for one REP token.
#<math>m</math> is the minting ratio.
#<math>r</math> is the base discounting rate.
#<math>L</math> is the lifetime after which a REP token expires.
