Poverty alleviation and artisanal mining in Tanzania

Wilson Mutagwaba
1998 Minerals & Energy - Raw Materials Report  
As a result of these problems the miners designed and fabricated manually driven fans for use in two deep pits.  ...  This is so because often, most miners are driven by the quest for wealth. They travel long distances or even cross borders into foreign countries responding to 'news' about mineral discoveries.  ...  ArtisanalMining: Mutagwaba, Mlaki and Mwaipopo-Ako recovering heavy minerals from gravels. Sluice boxes are not mechanized and use the energy of flowing water.  ...

Charlie Hou and Mingxun Zhou and Yan Ji and Phil Daian and Florian Tramer and Giulia Fanti and Ari Juels
2020 arXiv   pre-print
Designing incentive-compatible incentive mechanisms is notoriously challenging, however.  ...  As a result, most public blockchains today use incentive mechanisms whose security properties are poorly understood and largely untested.  ...  The incentive mechanisms of block rewards and fees have driven the remarkable growth of the Bitcoin ecosystem. In practice, poorly-designed incentive mechanisms can be exploited by rational users.  ...
