Your ultimate guide for everything Ethereum (ETH) when trivia night comes around.

1) In which year did Ethereum launch? 2015

2) What is the name of the standard used by tokens that run on Ethereum’s blockchain?

A) ERC-20
B) EIP-20
C) ETS-20
D) ETC-20

3) In 2016, Ethereum forked (i.e., split) into a separate network. What is the name of this?

A) Ethereum Cash
B) Ethereum Classic
C) Ethereum Genesis
D) Ethereum Original

4B) Bonus question: Why did this occur?

– A hacker took advantage of a vulnerability in a decentralised autonomous organisation (DAO) built on the network.

– There was a major division in the Ethereum community regarding how to handle this. Those in favour of reversing the fraudulent transactions created a new chain, which is the current form of Ethereum.  

– The other side – which insisted on upholding blockchain immutability – decided to continue from this hack under the original blockchain known as Ethereum Classic.

5) Who was NOT involved in the creation of Ethereum?

A) Vitalik Buterin
B) Gavin Wood
C) Andreas Antonopoulos
D) Charles Hoskinson

6) What is ETH’s all-time low price?

It dipped to 42 cents in October 2015, three months after its inception.

7) Which major network upgrade signalled the move from Proof-of-Work (mining) to Proof-of-Stake?

A) The London Upgrade (EIP-1559)
B) Proto-Danksharding (EIP-4844)
C) The Merge
D) Shanghai Capella (“Shapella”)

8) How many transactions per second can the Ethereum network process (specifically the main chain)?

A) 13
B) 35
C) 120
D) 500


9) Which company is working on blockchain-tech solutions primarily for Ethereum?  

A) Block, Inc.
B) MicroStrategy
C) Emurgo
D) Consensys

10) Name three stablecoins that run on Ethereum.
USDT (Tether) USD Coin (USDC), DAI (DAI), TrueUSD (TUSD), PayPal USD (PYUSD)

11) What is Ethereum’s all-time high price to date? Rounded to the nearest $100. $4,800

12) What’s the name of the software used by other blockchains to readily interact with Ethereum?

A) Ethereum Universal Machine
B) Ethereum Interoperability Protocol
C) Cross-Chain Interoperability Platform
D) Ethereum Virtual Machine

13) What is gwei, and how does it relate to Ethereum?

A) An ERC-20 token
B) A protocol built on top of Ethereum
C) A unit of measuring gas (i.e., transaction fees) on the network
D) A layer-2 scaling solution

14) Which of these decentralised exchanges (DEX) was NOT built on Ethereum?

A) Aave (AHH-vay)
B) Raydium
C) Uniswap
D) 1inch

15A) What was the name of the artist who sold a record-breaking NFT in 2021?
Mike Winkelmann (a.k.a. Beeple).

15B) How much did the artwork sell for? $69 million!

16) Which of these is a major annual Ethereum conference?

A) Devcon
B) The Global Blockchain Summit
C) Swell
D) Ethereum Con

17) What is Ethereum’s max supply?

A) 100 million
B) 200 million
C) 250 million
D) 350 million
E) It doesn’t have an official max supply

Context: Ethereum does not have a hard cap, unlike Bitcoin’s 21 million BTC. However, since the introduction of the London Upgrade (EIP-1559) in September 2022, ETH’s supply has peaked at around 120 million due to ongoing coin burning.

B) Ether Tracker
C) Ethereum Blockchain Explorer
D) Etherscan

19) What’s the main programming language used for Ethereum smart contracts? Solidity

20) How many ETH are required to become a solo validator for Ethereum staking?

A) 1
B) 8
C) 32
D) 128
Further info:

21) Which of these is an Ethereum upgrade?

A) Berlin
B) SegWit
C) Hydra
D) Babylon

“The Berlin upgrade optimized gas cost for certain EVM actions, and increases support for multiple transaction types.”

22) What was the name of the mining algorithm used by Ethereum up until The Merge?

A) Ethmine
B) EtHash
C) Scrypt

Harder questions

23) What is a Layer-2 Network? It is built on top of a base/main chain (e.g., Ethereum, a.k.a. a Layer-1) that handles various transactions per second off the main chain to boost an L1s scalability.

Visit L2 Beat for more details.

23B) Bonus question: What are examples of popular L2s?
Base, Optimism, Arbitrum, Immutable X, Linea, Starknet, etc. 

N.B. Polygon (MATIC) was originally built on Ethereum, but it now runs as a standalone chain, i.e., a sidechain. Nonetheless, it is still fully compatible with the latter.

24) What is an LSD? How does this benefit Ethereum?

A liquid staking derivative is an ERC-20 token pegged to the value of ETH (or any specified asset), which can be readily converted back into ETH.

This benefits the network’s users by allowing them to circumvent a locking-up (waiting) period built into certain networks, e.g., Ethereum, Polkadot, Fantom, Tezos, etc.

A few popular examples of LSDs on Ethereum include Lido Staked ETH (stETH), Rocket Pool ETH (rETH) and Coinbase Wrapped Staked ETH (CbETH).

25)  What is The Flippening?

It is a theoretical scenario whereby ETH overtakes BTC to become the top crypto asset by circulating market cap.

The closest we ever got to a Flippening was in June 2017, when BTC and ETH had a 38% and 31% market-cap dominance, respectively.
