Luke Dashjr and Christian Decker discuss the issue of malleability in Bitcoin.
Christian argues that the problem of singlesig users double-spending their outputs to update transactions remains a problem, even with the segregated witnesses approach. Luke disagrees, saying that signature malleability is what Segregated Witnesses solves, and that conflicting spends are sometimes useful for some contracts. They discuss the definition of malleability and its implications for Bitcoin transactions.
