基于激励相容的权益分散共识算法

PoW共识算法被证明是激励不相容的,存在高奖励差异下的算力中心化和极端情况下的分叉收敛速度较慢等问题。基于此,提出了一种基于激励相容的SSPoW共识算法。通过引入局部解来计算区块链的聚合算力,利用算力的显性量化加快分叉收敛速度,从而满足区块链的一致性。通过改进奖励方案实现激励相容,减少因高奖励差异导致的算力中心化问题。仿真结果证明,所提算法能有效削减奖励差异,并且效率高于传统Po W共识算法,对提高系统安全性和共识效率有积极意义。

The Convergence of 1-Periodic Branched Continued Fraction of the Special Form in Parabolic Regions

Branched continued fractions are one of the multidimensional generalization of the continued fractions. Branched continued fractions with not equivalent variables are an analog of the regular C-fractions for multiple power series. We consider 1-periodic branched continued fraction of the special form which is an analog fraction with not equivalent variables if the values of that variables are fixed. We establish an analog of the parabola theorem for that fraction and estimate truncation error bounds for that fractions at some restrictions. We also propose to use weight coefficients for obtaining different parabolic regions for the same fraction without any additional restriction for first element.
