SUMMARY:Thesis Defense "Governing the Commons in Blockchains"
DESCRIPTION:Blockchains are one of most appealing technologies over the
 last years\,\nboth for scientists and for the general public. Blockchains
 are\ndistributed ledgers that aim to offer transparency\, integrity and
 many\nmore advantages over their centralised counterparts. Blockchains
 were\n“revealed” and became popular thanks to the creation and raise of
 the\ncryptocurrency Bitcoin. Over the years\, blockchain technologies
 become\nmore and more popular with an exceptional peak in 2017. Blockchains
 are\nbecoming mainstream technologies\, as there is an observatory
 for\nblockchains established by the European Commission\, blockchain forums
 in\nmany countries\, blockchain start-ups are flourishing\,
 scientific\nconferences are discussing the topic\, and even some
 scientific\nconferences are now specifically dedicated to the technology\,
 etc.\nThe blockchain technology promises\, thanks to its integrity
 and\ntransparency properties to be useful and interesting in various
 domains\,\nand not only for financial systems. However\, many questions and
 doubts\nfloat around it. Is it environmentally viable? Is the technology
 even\nensuring its promises? Can they be used in real life settings\,
 etc.\nIn this thesis\, using the lens of distributed systems\, we study
 and\ndefined the properties of committee-based blockchains and
 their\nfairness\; that definition allows formalising and helping correct
 one of\nthe most used blockchain of that class. Furthermore\, adding lenses
 from\ngame theory\, we propose a methodology to analyse the rational
 behaviours\nof participants in a blockchains system. Using that
 methodology\, we\nshow\, under different mechanism of rewards\, the
 necessary conditions\nneeded to ensure the blockchain
 properties.\n\nParticiper à la réunion
