近期的币圈资讯,除了政策监管、各类会议外,安全问题占据着相当大的比重。
区块链领域里的安全问题,我概括起来主要分这么几种:
一:数字货币交易所被黑客盗币:Mt.Gox、Parity Wallet、Bitfinex、NiceHash、Coincheck、Coinrail等交易所都先后遭受过黑客的盗币,对当时的市场造成极大的利空影响。
二:51%算力攻击:起初这只是理论上的一个概念,但近期的BTG、莱特币现金(LCC)、ZEN等均遭受了51%算力攻击和双花问题,算是理论变成了现实,愈发引起圈内人对算计集中化的担忧。
三:智能合约漏洞:BEC、SMT、EDU、SNC等以太坊ERC20代币智能合约漏洞,NEO系NEP-5代币“存储区注入漏洞”等事件时有发生,轻则让单个币价太跳水,重则让市场情绪恐慌引起瀑布。
四:区块链节点网络漏洞:近期360曝出的EOS史诗级漏洞,60%的以太坊节点可在数秒内被轰塌等,对于拥有开发人数最多的2个主流公链币种都有这样的问题,其他的公链币种更加让人对安全问题的担忧。
五:其他问题:像黑客劫持他人电脑算力恶意挖矿(XMR),个人地址私钥被盗等。
上述的这几类安全问题,今年频繁发生,损失巨大。
作为去中心化的不可篡改的信任机制,区块链自身并不能解决安全问题,其链式数据结构所形成的账本只能保证记录的数据不可篡改(或是篡改的成本巨大而不容易发生),并不能保证数据本身的真实安全,需要更多的与其他技术手段结合才能实现。
We're in a bear trend bud, deal with it bulls. Do something else, rest for a year while bitcoin slumps. More opportunity awaits, more time to learn, more time to refresh your body and mind from checking your prices to buy at are coming

Great article. Yes, it does feel like we are in the "Trough of Disillusionment". Now, or whenever the bottom of the trough is, is actually the best time to invest. But human psychology is to stay away and only invest when the market is hot.

Thanks for this awesome blog.
Cryptocurrencies are more than just a speculative financial asset – the blockchain ledger behind them is the technology of the future. In fact, the majority of cryptos are best conceived as more of a technological asset than a financial one. Investing in a crypto gives you the rights to use that particular bit of software and technology that comes with the currency.
If one considers it just as a financial asset, you’re more than likely to get your fingers burnt. But if you consider it as a technology for the future, you’ll be backing the right horse.))

Blockchain definitely has a bright future. Cryptocurrencies aswell, eventhough the first bubble may have bursted, the price will raise again. Maybe not as sharply as it did, but in a more sustainable and healthy growth.
And obviously not all of them will success, but that's the main part of an investor job to do research on where to invest and why. Don't follow the herd, do your research and invest in project you would actually like to use in the future (aka not just for quick buck) and you'll find the right blockchains to invest in.

I believe that the Blockchain will rise again. In fact this is an oportunity to obtain crypto-currencies as an investment method, because when they peak up again... it will be time to cash out pretty well!!
