🔍 Researching zkEVM can be a real pain if you don't understand the technology.

Are you ready to be the pioneer in discovering the alpha?

Let's break down Zero-Knowledge Proofs in simple words!

👇

🔷 ZK-rollup technology has been gaining more and more attention lately:

Solving data privacy concerns and increasing decentralization, this mechanism offers interesting developments.

Let's find out how it works.⬇️

🔷 What is a zero-knowledge proof?

In this ingenious method, the Prover can provide evidence to the Verifier without compromising their privacy.

It's a way for someone to prove they know something without giving any specifics.

🔷 ZKP has 3 conditions:

Completeness - honest verifier convinced if statement is true.

Soundness - dishonest prover can't convince honest verifier of false statement.

Zero knowledge - verifier knows nothing beyond truth of statement.

🔷 The simplest example.

Suppose Prover and Verifier meet outside a house with a closed door inside.

Prover needs to prove to Verifier that he has the key to the door.

🔷 The first one to enter the house, Prover selects a route that leads to a closed door.

🔷 Now Verifier enters the house and asks Prover to come out of side 1.

🔷Imagine this scenario:

Prover doesn't have a key to the door, but he tries to cheat.

With a 50/50 chance he randomly chooses side 1.

Verifier could ask him to come out of side 1 and then Prover would not have to open the door.

🔷 If you do the experiment 100 times:

• The probability of Prover succeeding on all 100 attempts is almost zero (1/2)^100 = 0.000000000788.

• Prover can prove to Verifier that they possess the key by successfully exiting the door on the correct side at all 100 times.

💰 You are now covered! Good luck finding Alpha!

📛 Crypto scams have been around for years and also millionaires have fallen victim.

⬇️ To keep you safe, here are the most types of scams

Recent reports show that hackers stole ~$5 billion worth of crypto last year.

And lately, scammers have become very hungry and scams has increased dramatically.

List of the most widespread scams 👇 

1️⃣ Address Poisoning Attack

Scammers manipulate smart contracts to make you send tokens to an address similar to the previous one.

They hope you won't verify the authenticity and send funds to their wallet. Some wallet apps may even suggest the scammer's address for you.

Two options of this scam:

• Send a null transaction from a similar address to where your tokens came from.

• Create a transaction through a smart contract as if your wallet sent a null transaction. The most used networks: BNB, Polygon, Tron.

2️⃣ Dangerous signature

Users are requested to sign a message upon entering the site.

Though Metamask warns against it, some inattentive users still sign, resulting in their transaction being sent to the scammer's address along with all ETH.

There are some ways to sign:

• personal_sign

• eth_sign

Metamask only warns for eth_sign. It signs hash first and then message, removing "x19Ethereum Signed Message:n".

Personal_sign signs message first, then hash.

3️⃣Token approvals

It's important to remember that approving a contract token essentially grants permission for scammers to spend tokens from your wallet freely.

Many people think that additional confirmation is needed, but no - the approval itself is permission.

In case you approve an unknown contract by mistake, you may lose tokens.

Revoke Cash is the best option if you want to keep your tokens. Don't hesitate, act quickly and cancel any suspicious confirmations to avoid losses.

4️⃣ Security Update

If this signature is confirmed, consider your wallet lost.

The contract will automatically send all ethers from the wallet, leaving you with insufficient funds to withdraw any transactions.

Unfortunately, there is nothing you can do in this situation.

5️⃣ Seaport scam signature

This type of signature can lose all NFTs that have been approved on OpenSea.

If you accidentally sign something like this, you should immediately revoke the signature on etherscan or revoke cash

To avoid impact:

Remove all doubtful approvals.

Without open approvals, scammers can't steal. Check regularly and remove unnecessary endorsements, especially old Opensea endorsements (shown as OpenSea (old) on revoke cash).

6️⃣ Upgrade To.

This is a similar signature as Seaport, only approved to the old OpenSea Wyvern Exchange v2 (old) contract, cancels via revoke cash (shown as OpenSea (old) on revoke cash too).

7️⃣Scam links, drainers, malware.

• Be wary of scam links, drainers, malware and honeypot.

• Always double-check anything you open or download.

• Using a browser without a install-in wallet when browsing the Internet to provide added security for your finances.
