12月Cosmos Hub&Spoke 新闻的亮点:
在新年之际赢得Game of Zones(GoZ)
Cosmos Hub 3
通过测试跨链通信(IBC)原型进行通证转移,为GoZ做准备
Game of Zones: 2020年1月开启
Game of Zones是PoS历史上第一个对抗性测试网(即大约2018年的Game of Stakes)的续集,开启了激励性测试网的先河。 这次,参与者将使用跨链通信(IBC)协议建立并连接各个zone,尝试进入彼此的链。 作为交换,Interchain基金会向Game of Zones是奖池捐赠了 100,000 个ATOM。
抢先一步:
熟悉GitHub上Cosmos SDK的IBC分支。 注意:这些分支会随着时间而演变。
通过在测试网之间发送IBC交易进行练习。

CosmWasm 来到Cosmos
CosmWasm 是为Cosmos 生态系统建造的一个新型智能合约平台。如果你从未听说过它,请先阅读这篇入门级文章:CosmWasm宣布正式启动。本文的目的是给那些想把CosmWasm 融入到他们产品中的开发者更深入的介绍一下这项技术。尤其是针对那些有Cosmos SDK开发经验的Go语言开发者和在寻求区块链平台的Rust语言开发者。
在2019年柏林区块链周上,Gaians团队开发出CosmWasm的原型。Aaron Craelius提出了该体系结构,尤其是避免可重入,Jehan Tremback引导使用Rust语言编程,Ethan Frey实现了Go语言的实施。成功的原型制作完成后,Interchain基金会给Confio提供了资助,为了能创造出可在对抗环境中使用的强大版本。本文向开发人员介绍了该资助的工作成果,并提出了未来可能的方向。

实时链升级的解决方案
实时链上升级一直以来是一个挑战。Tezos,IRISnet,Regen Network和IOV Network的团队率先进行了链上升级。 Regen和IOV已实施了一个测试模块,用于基于Cosmos SDK的区块链的无缝软件升级。现在它正式成为Cosmos SDK的一部分。

cosmos:master
← regen-network:regen-network/upgrade-module
opened 07:26PM - 29 Apr 19 UTC
_This is a reopening of PR #3979 which was closed when the develop branch was re… moved. See that PR for previous discussion._
Upgrading live chains has been previously discussed in #1079 and there is a WIP spec in #2116. Neither of these provide an actual implementation of how to coordinate a live chain upgrade on the software level. My understanding and experience with Tendermint chains is that without a software coordination mechanism, validators can easily get into inconsistent state because they all need to be stopped at precisely the same point in the state machine cycle.
This PR provides a module for performing live chain upgrades that has been developed for [Regen Ledger](https://github.com/regen-network/regen-ledger) and tested against our testnets. It may or may not be what Cosmos SDK wants, but just sharing it in case it is...
This module attempts to take a minimalist approach to coordinating a live chain upgrade and can be integrated with any governance mechanism. Here are a few of its features:
- allows upgrades to be scheduled at a future block height or after a future block time
- crashes the blockchain state machine in `BeginBlock` when an upgrade is required and doesn't allow it to restart until new software with the expected upgrade is started
- provides a hook for performing state migrations once upgraded software is started
- allows for custom "crash" behavior that could be used to trigger automatic installation of the new software
This PR doesn't currently include any integration with the Cosmos gov module, but that could be easily done if this upgrade method works for Cosmos hub.
- [x] Linked to github-issue with discussion and accepted design OR link to spec that describes this work (linked to issues, the specification is described in the docs which are live here: https://godoc.org/github.com/regen-network/regen-ledger/x/upgrade).

- [x] Updated relevant documentation (`docs/`) - includes through go package docs

社群讨论了通过质押衍生工具实现一个DeFi世界的可能性
Chorus One的联合创始人Meher Roy认为,可以在目前供应缺乏流动性的情况下,在质押的ATOM上建立一个质押衍生品的市场,以创造流动性市场,在这种市场中,衍生品可以有更多的用途,而不仅仅是质押。提出此建议是基于以下3种衍生品发明的考虑:委托交易,委托凭证和委托款项。您可以在Cosmos论坛上找到有关验证人服务未来的讨论。

Introduction
In the Staking Hub telegram channel, Gavin (from Figment) asked this interesting question - is there any social utility to bonded, but unslashable, stake in a world of staking derivatives? This post dissects the problem and presents my view on the topic. It would be great to hear alternative opinions.
Detailing the question
In recent days, Solana announced its intention to have 100% of staked capital slashable. That policy is a radical departure from the design of the Cosmos Hub. O…
