比特幣分叉史(WIP)

[最近 Vitalik 發文討論了言論自由](https://medium.com/@feihutang/on-free-speech-24b646ea557f),提及了最近的幣安下架 BSV 事件以及 r/Bitcoin 上的言論審查。但是要完整理解這篇文章,必須對比特幣的分叉歷史有更全面的了解,Bitcoin Magazine 最近做了一份 [比特幣分叉地圖](https://twitter.com/BitcoinMagazine/status/1115274412239007744),就是很直觀的認識。

這裡我推薦下面幾篇文章:

零知識證明與區塊鏈擴容 Zero Knowledge && Blockchain Scalability

年前我報名了 03 月 25 日 在台北舉辦的 SITCON,正好看到 Changwu 分享 Vitalik 03 月 15 日會來 Taipei Ethereum Meetup 的活動,於是就決定提前動身。Vitalik 當天在台北的行程也安排的很滿,一共會出席三個活動 [1]。但根據我以往的經驗,最重要的活動當然是晚上的 Taipei Ethereum Meetup,每次 Vitalik 來 Taipei 都會帶來一些新的 idea[2],這次果然也是如此。

zKSnarks 和 Layer2 我們都不陌生,但是 zKSnarks 可以用來做擴容[3],很多人包括我就是第一次聽說了。再把這個結合進 Layer2,知道的人恐怕就更少了。

在這次的演講中,Vitalik 首次提出了自己對這一問題的一系列想法,以及其 Layer2 中數據可用性問題(Data Availability Problem)的聯繫。下面是這次演講相關的資料,其中 Trenton Van Epps 在 Medium 上忠實的記錄了這次 Tech Talk 的 Transcript,並且包含了許多相關的資料和歷史記錄,強烈推薦大家閱讀。

Magical Crypto Friends - Magical Cryptoland

It's time for adventures and lots of fun,
with pony, lion, panda, and chikun!

Magical Crypto~
All around me I see big block heads bobble

The best thing to do is simply to HODL

What's a young pony to do in a sea of shady ICOs?
A lion's courage can light up even the darkest of shadows.
Unlike the corporate suits, the WhalePanda is wise.
A chikun dream about the moon, while soaring in the skies.
As Bitcoin sees new all-time highs!

All around me I see big block heads bobble.

The best thing to do is simply to HODL.

When scam coins try to turn the tide, you'll quickly rush to my side.
Frauds and fake satoshi's will clown, but I'm not scared if you're around.
We'll always run a full Bitcoin Core node.
Scaling the right way is a long and challenging road.
SegWit is now here - for the UASF we cheer.
Layer 2 solutions are a must,
Always verify, don't trust.

We'll always buy the dip,
And we'll always be the best friends!
