1/6) Solana was DDoS attacked again yesterday

This attack exploited fundamental design flaws which are considered features by SOL

As it sacrifices decentralization & security for speed

While ignoring the consequences of that trade off

Specifically Proof of History & Turbine:

2/6) A consequence of PoH is deterministic block creation:

There is a good reason why public blockchains before SoL did not take this route

Non-deterministic block creation adds to security & censorship resistance as you cannot predict who will create the next block

3/6) Instead in SoL it is possible to predict & therefore attack the next block producers inline

For instance attacking the next 100 validators inline instead of attacking the entire network

This attack also works regardless of scale, thereby severely reducing SOL security

4/6) SOL security is not just reduced against DDoS attacks since this attack can also be combined with a 51% attack

Allowing an attacker to temporarily gain proportional staked control over the network by attacking other large stake holders

These are all consequences of PoH!

5/6) Combining Turbine with PoH leads to even more dire consequences:

Turbine divides the transaction memory pool into small groupings of validators

This means that with PoH you can censor transactions by just attacking the specific validators in that grouping next inline!

6/6) This is just one aspect of SOL's design that exposes the bad faith of its creation

Prioritizing attracting ignorant cryptocurrency investors over good sustainable blockchain design

There are many examples like this in terms of design as well as lies & fraud, buyer beware
