Back in Bitcoin history, when Argentinian millionaire Wences Caseres ( Xapo, Paypal) came across Bitcoin he saw it as a potential solution to the periodic financial turmoil that totally wipes off the wealth of hard working Argentinians. In what I consider a very prudent act of due diligence, he paid a couple of hackers a sizable amount of money to hack and break the fledgling Bitcoin. Their conclusion was that it was unbreakable and that has remained true until today. The Bitcoin protocol has never been hacked. The vulnerabilities were the trusted infrastructure around it like the exchanges. The most memorable being MT Gox.
However on the 1st August 2017, Bitcoin main chain forked and a new coin Bitcoin Cash (BCH) came into existence. Some argue that it is closer to Satoshi's vision than the current Bitcoin (BTC) which separate the data portion from the address portion of the data structure. BTC became the main coin because it was supported by the majority of users, developers, Bitcoin businesses and miners in what is now knows as the New York Agreement.
Chain Death Spiral. (CDS)
After Bitcoin fork on 1 August it became obvious that Bitcoin the protocol did have an inherent vulnerability. This was that if the chain loses mining power it will have to wait a full 2016 blocks before the difficulty can be adjusted to bring the block time back to the normal 10 minutes. This vulnerability was never considered or analysed because until now the miners had no choice but to keep mining on the Bitcoin chain. After the fork however, the whole landscape has changed. Miners have a choice and power to influence the fate of the chain they are mining on.
This was brought clearly into focus when the blocktime of the BCH fork went as high as 15 hours per block in the beginning. BCH however was designed with Emergency Difficulty Adjustment (EDA) which adjusted the difficulty even before the 2016 block adjustment period is up. Bitcoin (BTC) does not have this safety feature and cannot have one unless a hardfork is performed to include it.
A Chain Death Spiral occurs when the block time increases leading to some miners switching chain. As more miners leave the problem gets worse and a feedback loop results in the dreaded Chain Death Spiral.
Bitcoin (BTC) mempool been increasing since after the fork on 1st August. It is currently 52MB which means it will take 52 blocks to clear without any additional transactions. The record was in May 2017 when it reached 120MB. The whole community was in an uproar resulting in a move towards other competing coins for transacting.
