Nothing Considered: A look at Nothing at Stake Vulnerability for Cryptocurrencies
presstab, Core Developer, Blockchain Energy
Abstract — Nothing at stake is a routine argument launched against any and all Proof of Stake proof systems. Although the argument has some interesting components to it, it is should be seen as something of very little concern for a Proof of Stake based cryptocurrency. A wide distribution of staking power as well as a wide distribution of honest nodes will easily prevent any line of attack from the nothing at stake scenario.

Few industries impact global economic livelihood, societal functioning, and quality of life as significantly as the energy industry. Few industries face as many challenges. A number of daunting factors are again leading many inside and outside the energy industry to embrace renewable energy as a solution — or, perhaps, more accurately — a critical piece of the solution. Renewable energy sources are making inroads in our national energy mix, and that progressis likely to continue. It’s not a matter of whether the renewable energy market will grow, it’s how fast and by how much.
This is exactly the kind of achievement we should be proud of. The difference that they bring to many families and businesses around the world is incredible. …
All concentrating solar power (CSP) technologies use a mirror configuration to concentrate the sun’s light energy onto a receiver and convert it into heat. The heat can then be used to create steam to drive a turbine to produce electrical power or used as industrial process heat.
Concentrating solar power plants can integrate thermal energy storage systems to use to generate electricity during cloudy periods or for hours after sunset or before sunrise. This ability to store solar energy makes concentrating solar power a flexible and dispatchable source of renewable energy.
CSP systems can also be combined with combined cycle power plants resulting in hybrid power plants, that provide high-value, dispatchable power. They can also be integrated into existing thermal-fired power plants that use a power block like CSP, such as coal, natural gas, biofuel, or geothermal plants. …
