Polygon and Ethereum

Whenever a magazine or newspaper picks up the topic of cryptocurrencies, the article is usually actually only about Bitcoin. Yet it is only one of many cryptocurrencies. Ethereum, for example, has the second-largest market capitalization after Bitcoin and is technologically far superior to the latter in many respects.

Compared with Bitcoin, Ethereum offers:

lower transaction fees
shorter transaction times
higher transactions per second
the innovation Ethereum Virtual Machine (EVM), which can execute programmed agreements (smart contracts)
the innovation decentralized exchanges (DEX)
the innovation decentralized organizations (DAO)

Ethereum was officially launched on 30 July 2015 – six years after Bitcoin. It is a modern and very popular blockchain. It is the most popular blockchain with smart contracts and the energy-efficient proof-of-stake mechanism.

Crypto Wallet Setup

This post explains how to set up a crypto wallet for self-custodial storage of your cryptocurrencies in under 10 minutes.

The setup is simple and without unnecessary fuss:

no registration
no video identification
no setup fees

All you need is your smartphone.

Self-Custody

In this context, self-custody means that you will be in possession of the private keys to your digital assets.

This is not the case with many crypto platforms such as Bitpanda, Coinbase, Binance, or Boerse Stuttgart Digital Exchange. There, you are provided with a wallet address. However, you do not control the associated private keys; the platform does.

After you have set up your Exodus wallet, you can sign in on our website. In this article, we show you the two required steps to connect your wallet and sign in securely:

Connect your wallet
Sign the request and sign in

This flow is similar to sign-in methods you already know. In those flows, you usually enter your email address first and then your password. Sometimes a two-factor authentication (2FA) step follows, where you must enter an additional one-time code.

Crypto Glossary

This glossary briefly explains frequently used technical terms. Either the English spelling (Crypto Wallet) or the German spelling (Krypto-Geldboerse) may be used.

In this context, the term definitions of the European Union are also helpful. See Art. 3, Regulation (EU) 2023/1114, MiCA - Markets in Crypto-Assets Regulation.

Altcoin: Altcoin is a portmanteau of Alternative and Coin. It refers to all cryptocurrencies except Bitcoin, i.e., alternatives to Bitcoin.

Asset: Asset is the English word for a valuable possession.

Bitcoin (BTC): Bitcoin is both the name of a blockchain implementation and the name of the associated digital currency.

Blind Signing: Blind signing in the context of cryptocurrencies means that a transaction or a smart contract is approved without the full content or details of the transaction being visible. This often happens due to the complexity of smart contracts and the limitations of crypto wallets, which cannot display all information in an easily understandable format.

Technically Verifying Polygon: Checking Whitepaper, Source Code, and Active Contracts

Summary

This article shows in seven steps how the core claims about the POL token can be technically verified.

At the reviewed state, the technical assessment yields three key findings. First, the initial total amount of 10 billion POL is directly traceable in the Token contract. Second, the emission logic in the current code is implemented deterministically and corresponds to an annual rate of around 2% with compounding. Third, role checks and Proxy history can be used to determine which contract version is currently executing this logic.
