1/ SOLANA: SAFER THAN ETHEREUM

Memecoin mania happened on Solana. To the same extent, it can never happen on any EVM chain.

Let's examine Solana's SPL tokens and why they offer a better user and developer experience than ERC-20 and how is this related.

A short thread.

👇👇👇 2/ What if I told you, tokens can be done better?

1/ THE BITCOIN DEFI AND WHY DID NOT GET IT YET

Why all the current Bitcoin L2s are 💩

A short thread and on trust assumptions

👇👇👇 2/ Bitcoin has existed 15 years. But even for a Bitcoin maxi, it's quite a stretch to say Bitcoin is technology-wise doing much compared to alternative blockchains.

1/ SOMEONE JUST LOST $5M in an ERC-20 phishing transaction using so-called increaseAllowance() method.

ERC20 phishing scams netted $50M/m to the bad guys, mostly using permit(), increaseAllowance(), approve().

What are these methods and why do people keep losing money?

👇👇👇 2/ This is a story where common sense is not on a driver's seat, or not even on a navigator's seat.

It's a story where good-meaning fools caused the creation of wallet drainer cybercrime industry, causing hundreds of millions of losses.

STARS ARENA HACK AND ITS IMPLICATION TO AVALANCHE

The new darling of Avalanche got hacked twice on two subsequent days, for $3.5M. Avalanche ecosystem and its investors are rushing to make the project whole.

Why did this happen, and what can we learn from this?

👇👇👇 BACKGROUND

Let's lay down facts and see what we have on the on-chain drama plate this week.

👇👇👇

REAL-WORLD ASSETS - DO THEY EXIST ON-CHAIN YET?

Maybe. Due to popular requests and feedback from happy Twitter users, we have made a spreadsheet where you can start tracking Real World Asset Revolution ™

1/ A SCAM YOU SIGNED YOURSELF

Crypto wallet signature and approval scams are rampant.

Why does this happen?

What actions can a community take to prevent these scams?

Is this universal: is it specific to Ethereum's design, are other blockchains safer? 2/ There are two kinds of problematic transfers in the financial world: authorised and unauthorised. In this Twitter thread, we focus on authorised transfers - i.e. the account owner signs the transfer himself.

1/ WHAT EUROPEAN CENTRAL BANK HAS IN MIND FOR THEIR #CBDC PILOT?

I read through the onboarding package.

TL;DR: ECB copies #bitcoin and makes a centralised version of it.

👇👇👇 2/ First the sources: the information is available on ECB site. More information in this good post by by @Finextra

1/ SO YOU WANT TO BE A SMART CONTRACT AUDITOR?

Here is a list of resources to get started. For #ethereum, #solana, #cosmos, #near or any ecosystem.

👇👇👇 2/ In a smart contract security audit, or "smart contract audit" for short, usually a third party reads through the code written by the project smart contract developers and they look out for security vulnerabilities.

1/ ELON THE GREAT LEADER, SAVIOR OF TWITTER

Let's fire all incompetent donut eaters and turn the company around.

What could go wrong?

Here is a thread on Twitter restructuring, from the management and leadership theory perspective.

👇👇👇 2/ I studied industrial engineering and management at uni. It was mostly fluffy studies, but there were some gems in our courses.

The best bits were related to company management and leadership. A lot of course material was case studies.

1/ ERC-20, THE ORIGINAL SIN

Why #Ethereum blockchain wallets and tokens are unsaveable mess and why other blockchains will eventually take over?

A short dive into the broken token standard that cannot be fixed.

👇👇👇 2/ Today we have two announcements related to the ERC-20 token standard, from @coinbase and @Uniswap

1/ Energy crisis is global.

Maybe we finally star to see some true demand flex:

Here are some countries: 2/ USA

1/ 🌪️ TEMPEST IN A TEAPOT 🌪️

...or Tornado Cash on the #ethereum chain?

Unpredecent events unfolding... is it about the mastermind criminals, North Korean spies, privacy keyboard warriors or ignorant fools?

Have your ☕ ready. Let's go for a long thread!

🌪️ 🌪️ 🌪️ 2/ TornadoCash is the most famous smart contract-based privacy transaction tool othe #ethereum blockchain using so-called shielded transactions (more about the model later).

1/ DID YOUR #SOLANA WALLET JUST GET HACKED?

Or should I say sloped.

If not yet... then you might be the next!

A quick thread on the security of blockchain applications and how to watch out for rotten products out there.

👇👇👇 2/ Everything in cryptocurrencies is based on the principle of "trust, but verify".

If something is not open and auditable by third parties, it is not crypto by a definition.

1/ WILL COSMOS TAKE A LEAD IN THE BLOCKCHAIN RALLY?

A dive into the @cosmos ecosystem.

I had the pleasure to participate in HackAtom Seoul 2022 hackathon last weekend.

Here is what I learned and you can learn from this Twitter thread as well.

👇👇👇 2/ I'd like to thank HackAtom organisers @buidl_asia, @kryptoseoul, @ekang426 and others for the massive successful events.

1/ A smol thread on Coinbase insider trader fraud charges.

A different perspective: should a listing event be considered as insider information in the first place?

While everyone might think "d'oh, obviously" let's throw in some critical thinking and facts.

👇👇👇 2/ Mr. Wahi and his conspirators allegedly made $1M+ by frontrunning Coinbase listing.

- Wahi knew about the listing decision and date
- He shared this information with his brother and a third party
- Sers bought some coins on a day before the listing

1/ WHAT IS THE FUTURE OF DEFI AND CEFI?

Why #DeFi on-chain markets are the future and what is Trading 3.0 going to look like? How is the current crypto market stress going to reshape the market microstructure?

A thread.

👇👇👇 2/ May you live in interesting times.

- An old Chinese curse

1/ BAD SECURITY AUDITORS IN CRYPTO SPACE

What does a bad cop smell like? A case study with one "audit" report of a scam project. What kind of audit report is a red flag and who are the dishonest auditors working with scammers?

A thread

👇👇👇 2/ As a preface, to set the baseline of understanding, the security audit of a smart contract should have two audiences:

Flamingo NFT vs. The state of New Jersey

linkedin.com/feed/update/ur… Russian scam. No surprise here.

1/ THE END OF TERRA AND WHAT'S NEXT

More importantly: WHAT IS FAIR FOR THE PARTICIPANTS?

A thread

👇👇👇 2/ What cannot be saved, cannot be saved.

In the end, Do Kwon did not have enough billionaire friends for $6B bailout. Better to let the burning platform to sink, instead of destroying value by trying to keep it afloat.

1/ The short history of algorithmic stablecoins, fractionally backed family.

Some inherited unstableness goes in the blood.

A thread.

👇👇👇 2/ The last night was intense as $8B algo stablecoin Terra was about to crash. Looks like the $UST peg is restoring for now. Let's see if billionaire buddies make a difference.

I do not wish to see Terra collapse uncontrolled, but I see a lot of people losing their faith.

1/ CAN #DEFI SMART CONTRACTS EVER BE SAFE?

Is it possible to write bug-free software?

No spoilers, to get the answer you need to read this thread on Twitter *NOW*, before Muskalypse starts.

#infosec #ethereum

👇👇👇 2/ #DeFi keeps scoring higher and higher in the value of "hacks", counting losses in dozens of millions of dollars. This will make the users legitimately worried.
