Methods and systems for a heterogeneous multi-chain framework
Present-day blockchain architectures suffer from several problems, including poor extensibility and scalability. This may stem from tying two parts of the consensus architecture, namely canonicality and validity, too closely together. The Polkadot architecture, which is a heterogeneous multi-chain, provides better extensibility and scalability by setting canonicality and validity apart. Compartmentalizing canonicality and validity and keeping overall functionality to a minimum of security and transport introduces practical core extensibility in situ. Scalability is addressed through a divide-and-conquer approach to canonicality and validity, scaling out of its bonded core through the incentivization of untrusted public nodes. The heterogeneity of this architecture enables many highly divergent types of consensus systems interoperating in a trustless, fully decentralized “federation,” allowing open and closed networks to have trust-free access to each other. This architecture is compatible with pre-existing networks, including Ethereum, and a useful component in a practical system for global-commerce scalability and privacy. |

Current sourcing or sinking continues until the voltage across the corresponding charge pump capacitor approximates a target voltage, at which point the comparator output toggles, which results in uncoupling of the coupled current source or current sink from the corresponding charge pump capacitor. Embodiments only need one current sink and one current source per charge pump capacitor, and charge balancing is independent of leakage currents. |

Electrical storage device with negative capacitance
The energy density of capacitors can be increased by using a material with differential negative capacitance (NC), which was recently observed in FE materials. Described is a more general pathway towards improved electrostatic energy storage densities by engineering the capacitance non-linearity of electrostatic devices. The disadvantages of regular polarizable materials are overcome by using the NC effect, which ideally has no hysteresis losses, leading to a theoretical efficiency of 100%. By storing the energy mostly in an amorphous DE layer, the break-down field strength is much higher compared to pure FE or AFE storage capacitors. In addition, leakage current losses can be reduced by improving the morphology of the insulating materials used. |
