DESCRIPTION:Offchain networks are dominant as a solution to the scalability
  problem of blockchain systems\, allowing users to perform payments withou
 t their recording on the chain by relying on predefined payment channels. 
 Users together with the offchain channels form a graph\, known as the offc
 hain network topology. A pair of users can employ a payment even without a
  direct channel through a path of channels involving other intermediate us
 ers. The offchain topology and payment characteristics affect network perf
 ormance such as latency and fees.\n\nWe study basic demand-aware problems 
 in offchain network design: Efficiently mapping users to an offchain topol
 ogy of a known structure as well as constructing a topology of a bounded n
 umber of channels that can serve well typical payments. Likewise\, we sugg
 est an approach for jointly serving multiple payments by finding an equiva
 lent set of payments that has the same impact on user balance but can be s
 erved efficiently in a given topology.\n\nSpeaker(s): Ms. Julia Khamis\, \
