研究为保证对改善世界发展技术的道德, 责任的使用合理环保的技术生态系统的渠道

随着区块链技术在世界各地的蓬勃发展,我们认为,继续研究和评估这项技术的潜力至关重要。我们的白皮书和情况说明书解决了区块链社区中一些最为紧迫的问题。

Flare:闪电网络中的路由选择方法

Jul 07, 2016

本白皮书介绍 Flare,一种用于闪电网络支付路由的混合路由算法。本文提出一种两阶段算法:(1) 主动更新节点的路由图,存储有关网络拓扑的信息,以及 (2) 根据闪电网络请求的需要,按需被动收集信息。这份白皮书首次尝试描述和初步测试算法解决方案,用于未来比特币区块链闪电网络的实施,这将允许交易处理的可扩展性。论文是与合著者 Olaoluwa Osuntokun 以及闪电网络团队其他成员合作的成果。

每个人都应该了解的有关区块链的 4 个事实

May 12, 2016

是否需要快速了解为何人人都对区块链和比特币技术感兴趣?

公共区块链中的数字资产

Mar 15, 2016

Bitfury 集团的白皮书“公共区块链中的数字资产”探讨如何在保障比特币安全的公共区块链安全地存储和转移数字资产。数字资产是由资产发行人担保的某项服务或商品的流动债权,由计算机技术和互联网管理。在撰写这份白皮书的整个过程中,Bitfury 集团发现,使用区块链架构进行数字资产管理将允许全球经济创建纯粹的数字资产,并完全在线管理这些资产。我们的白皮书得出结论,这项福利将为拥抱世界各地的机遇打开许多新的大门。

保护比特币区块链的激励机制

Dec 07, 2015

本白皮书研究为比特币区块链提供安全性和不变性的两大激励机制:大宗奖励和交易费。我们研究这些激励措施在提供比特币区块链对区块链重组和拒绝服务攻击的弹性方面发挥的作用,以及在新兴的非连锁支付方式下区块链安全的来源。机器间/物联网支付也受到审查,因为区块链技术可能对组织分散经济产生有利影响。最后,我们基于现有和新兴的比特币应用,提出了一种估计比特币网络中期总交易费用的方法。

公共与私有区块链

Oct 20, 2015

基于区块链的解决方案是机构研究的主要领域之一,尤其是在金融和政府部门。毫无疑问,这些行业目前使用的主干技术已经过时,需要进行一次彻底改革,以适应时代的需要。区块链形式的分布式或分散式分类账是对所述问题讨论最多的潜在解决方案之一。

Mathematical formalism for the voting process in Bitcoin ecosystem

Sep 13, 2015

We propose a mathematical formalism for the voting process in Bitcoin ecosystem. This formalism can be used to algorithmically determine the best value of a certain parameter (e.g., a block size limit) which will be considered appropriate by all voters. The proposed approach is aimed to clarify vagueness of some proposed voting processes that potentially allows a party with marginal voting power to dictate their conditions to the rest of the network. To solve the problem, we introduce a non-negative dissatisfaction function and minimize its value summed over all votes. The value of the block size limit (and, potentially, other parameters of the protocol) found this way will satisfy voters provided the dissatisfaction function is chosen appropriately.

Proof of Stake vs Proof of Work

Sep 11, 2015

Proof of stake is a consensus mechanism for digital currencies that is an alternative to proof of work used in Bitcoin. The main declared advantages of proof of stake approaches are the absence of expensive computations and hence a lower entry barrier for block generation rewards. In this white paper, we examine the pros and cons of both consensus systems and show that existing implementations of proof of stake are vulnerable to attacks which are highly unlikely in Bitcoin and proof of work approaches in general.

Bitfury Report On Block Size Increase

Aug 31, 2015

We believe that in order for Bitcoin ecosystem to prosper, the maximum block size must be increased. It is a common understanding among Bitcoin developers that the current limit of one megabyte hinders scalability of Bitcoin Blockchain and prevents its wide adoption as the technology of the future.

Smart Contracts on Bitcoin Blockchain

Aug 13, 2015

Smart contracts are one of the more promising directions for cryptocurrencies and Bitcoin in particular. A smart contract is understood as a computer protocol used to facilitate and automate financial contracts. The term smart contract was introduced by Nick Szabo in 1990s and became more relevant than ever before in 2010s after digital currencies gained popularity.
