ETH2 merge looms large as developers migrate to Polygon

High transaction costs, known as gas fees, and intermittent network outages are putting pressure on the world’s second-largest cryptocurrency blockchain to complete its long-planned – and frequently delayed – protocol merge to Eth2, according to 21Shares research lead Eli Ndinga on the digital asset manager’s first media roundtable on Wednesday.

Specifically, 21Shares has seen developers migrate to the competing Polygon blockchain as non-fungible token (NFT) sales and trading continues to grow.

“The Ethereum merge is expected in the second half of 2022,” Ndinga said, noting Ether is the cryptocurrency of choice among the NFT set. “If that doesn’t happen, we expect we will see further migration to Polygon.”

Other gas also high

Driven by high and often unpredictable gas fees, which fluctuate based on transaction volume, as well as the relatively high carbon footprint associated with mining Ether, the Ethereum network has been developing this merge throughout last year.

During peak transaction times, Ether gas fees can reach into the hundreds of dollars per transaction. High gas fees were cited by the creators of ConstitutionDAO as a hurdle to redeeming donations after it was unsuccessful in its bid to buy a copy of the US Constitution.

With the gas fees incurred during the initial contribution, and based on the roughly $200 average donation, requesting a refund just wasn’t worth the gas.

Additionally, mining Ether is a relatively energy-intensive process driving the network’s unsustainable carbon footprint.

Awaiting the merge

The merge, integrating the already running beacon chain with the Ethereum main net, will change the consensus mechanism to a proof of stake from the current proof of work mechanism, or Ether mining. This merge will theoretically shift the consensus mechanism while maintaining the historical transaction integrity currently on the blockchain.

The merge to Ethereum 2 (Eth2) had been expected early in 2022, but 21Shares predicts it will be completed later in the year, further boosting Polygon’s progress.

Developer migration

“Developers are moving from Ethereum to Polygon,” Ndinga added during the roundtable. “The Ethereum merge is expected in the second half. If that doesn’t happen, we will see further migration to Polygon.”

Polygon is a relatively new, and much smaller network – with a $16.4bn market capitalisation versus Ethereum’s $294.5bn – launched in 2019 as MATIC as a Layer 2 Ethereum-compatible blockchain network.

Created by former Ethereum developer Sandeep Nailwal, Polygon’s designed scalability reduces transaction costs to fractions of a cent.

As developers migrate and transaction volume increases, Ndinga added, “It’s possible Polygon will experience the same problems as Ethereum, but Polygon is doubling down on its infrastructure.”

This doubling down, as Ndinga called it, is Polygon’s collaboration with accounting firm EY, called the Polygon Nightfall ZK-Proof, which is currently being developed.

Additionally, while not technically a migration, the Great Resignation the US economy has experienced over the past year has fuelled the growth in the number of developers, added Ndinga. Notably, former tech employees have left the workforce and entered the Web3 and cryptocurrency spaces.

Polygon’s currency, MATIC, currently trades at $1.54, versus Ether’s current $2,458.70 price, according to data maintained by Coindesk.

The difference between trading assets and CFDs
The main difference between CFD trading and trading assets, such as commodities and stocks, is that you don’t own the underlying asset when you trade on a CFD.
You can still benefit if the market moves in your favour, or make a loss if it moves against you. However, with traditional trading you enter a contract to exchange the legal ownership of the individual shares or the commodities for money, and you own this until you sell it again.
CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. But with traditional trading, you buy the assets for the full amount. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. Stocks and commodities are more normally bought and held for longer. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely.
