The Ethereum Foundation is currently working on a multi-stage migration to the PoS algorithm, which will allow validators to create blocks by staking assets, instead of mining. A shadow fork of the Ethereum mainnet went live on Tuesday, bringing it a step closer to the transition from proof of work to a proof-of-stake consensus mechanism for the Ethereum 2.0 upgrade. But while van der Wijden will defend Ethereum’s PoS against claims that it isn’t really decentralized or that it’s vulnerable to exploits, he does acknowledge that some people may be expecting too much from the initial merge. This includes people within the Ethereum community itself, some of whom have an expectation that the merge will reduce gas fees, which have risen notoriously high at various points throughout the past year or so. Once a new shard block proposal has enough attestations, a “crosslink” is created which confirms the inclusion of the block and your transaction in the beacon chain. Proof-of-stake is a type of consensus mechanism used by blockchain networks to achieve distributed consensus.
However, the economics of that game are also inherently speculative because the majority of people can only make money if the number of new players continues to grow. A video game naturally runs into competition and a finite scale at some point, at which point the majority of participants would no longer be making money from the game. There was an example back in October 2021 where CryptoPunk #9998 sold for $532 million. However, upon further analysis, it turns out that the buyer used a DeFi protocol to sell the asset to their own self, with a massive flash loan. They then tried to list it for $1 billion, but of course nobody wanted to buy it at that price.
This is only possible with a non-fungible asset; you can’t manipulate the price of an individual bitcoin or an individual ether on your own, you can only manipulate unique objects like for example CryptoPunk #9998. Then, with prices so high, some people want to get in on the eth proof of stake momentum and buy the NFT, so the person who was trading among their own wallets finally sells the asset at a higher price to that unsuspecting newcomer. When that newcomer tries to sell the asset, he or she is unable to find other buyers who actually want to pay that price.
It’s the attestation that is recorded in the beacon chain rather than the transaction itself. The beacon chain receives state information from shards and makes it available for other shards, allowing the network to stay in sync. The beacon chain will also manage the validators from registering their stake deposits to issuing their rewards and penalties. Unlike proof-of-work, validators don’t need to use significant amounts of computational power because they’re selected at random and aren’t competing. They don’t need to mine blocks; they just need to create blocks when chosen and validate proposed blocks when they’re not.
Unique game items can include digital pets, or in-game items, or in-game land/property, and they can be sold to other players or even removed from the game and potentially accepted by another game that recognizes them. I don’t have the answers to these questions, other than that with technology that currently exists or that is foreseeable on the horizon as of this writing, they’re clearly not suitable for truly decentralized global money in the same way that the Bitcoin network is. They might work for gaming, permissioned payment systems, trading, and that sort of thing, but time will tell if they can survive past the speculation phase and regulatory arbitrage phase that they are now in. A fully-centralized database has fewer limitations, because it doesn’t need to be small and tight.
Prior to this, developer Tim Beiko was noting that “even though the merge testing is going well, it isn’t going to happen until the difficulty bomb is due to go off again (early December, as per EIP-3554). We are not ~1 month away from having client releases ready for the merge, so we need to push the bomb back again.” There seems to be some opposition coming from the miner community, so the EIP-4345 is granting it more time to prepare. However, one should keep in mind that the time bomb will not immediately impact mining difficulty, as it could take several months for block times to increase significantly. Furthermore, the proposal also notes that the difficulty bomb could be pushed back even further if necessary. The shadow fork explorer site was down at midday Asia time on Tuesday, but the network had processed around 1.8 million transactions with an average block generation time of around 13.8 seconds by early morning. The developer also explains that the initial merge is only the first step in a relatively long process, and that its immediate effect won’t be to make Ethereum much more capacious and scalable.

Instead, proof-of-stake mainly seems less suitable for a decentralized and censorship-resistant global monetary asset, especially when considered along with the issues that I’ll describe in the second half of this article about stablecoins. Proof-of-stake is inherently equity-like rather than money-like, compared to proof-of-work. Okay so as we discussed, proof-of-work is a system where miners compete with electricity and processing power to build the longest blockchain, which becomes the accepted blockchain. The digital blockchain, via proof-of-work, is thus connected to real-world natural resources. The Ethereum network currently has a proof-of-work consensus mechanism and in time, the protocol plans to fully transition into a proof-of-stake network.
Wall Street actually kind of loves DeFi in the tactical sense, because in aggregate they understand the idea of leveraging, liquidity management, exchanging, and arbitraging inefficiencies, and don’t really care about decentralization or technical details as much. Though over 80% of miners signaled intention for SegWit2x and the New York Agreement, it failed to gain any consensus among the community and Core developers. The existing developers and most importantly the majority of the individual node operators were not on board with the plan, and so along with multiple other reasons, it was aborted.
Top Narratives About Ethereum And Its Merge With Its Proof
A proof of stake mechanism sees cryptocurrency users contribute to network validation by depositing a certain amount of cryptocurrency into that network as a stake. In order to remain decentralized—that is, operating without a central authority—cryptocurrency networks work by incorporating a consensus mechanism, which means all computers on that network can agree on what’s going on at any given time without a central bank intermediary. The developers of the second-largest cryptocurrency in terms of https://xcritical.com/ market capitalization continue to transition the network to Proof-of-Stake . It’s clear that Bitcoin won as far as decentralized proof-of-work blockchain money is concerned. And I think people underestimate the total addressable market size of that concept. So, a big topic that the market is still assessing, is whether these partially-centralized smart contract platforms have a big role to play alongside the Bitcoin network, or if they’ll eventually stagnate as previous altcoin speculations have.
How we aim to achieve that is to first implement slashing proofs without any automatic slashing whatsoever. And among those new proof-of-stake competitors, there are multiple examples of their systems running into technical problems. The Bitcoin network has operated via proof-of-work since inception in 2009, and with no plans to change that.
- With a proof-of-stake system, the more coins you have, the more voting power you have, and those with the coins are also the ones earning the new coins from staking.
- The same is not true for the other direction, since it is the Bitcoin network that has a far larger network of miners and energy usage than them, by two orders of magnitude.
- Implementing EIP 1559 while delaying the shift towards Ethereum 2.0 is actually kind of a perfect storm for price in a positive way for the year ahead.
- And wires often get delayed or blocked or run into other problems as they flow between banks.
- The same tends to be true for social network platforms, as well as financial exchanges.
They didn’t make owning or trading cryptocurrencies illegal (that’s very hard to enforce), but instead they went with the simpler move of severing crypto from any formal connection with their domestic banking system. You can’t take Nigerian fiat currency and easily send it to a crypto exchange to buy bitcoins, in other words. For people who prefer to avoid centralized exchanges, there are various peer-to-peer technologies that make this easier than an in-person meetup like that. Bisq, Hodl Hodl, LocalBitcoins, and Paxful are all various ways to do peer-to-peer bitcoin exchanges, and each have different trade-offs but don’t require external tokens.
This may have repercussions on the GPU supply, as miners will likely continue to hoard cards until the end of 2022. Users can stake their tokens in the Ethereum 2.0 network by sending their Ether to a deposit contract, which they must do by following instructions on Ethereum’s Launchpad product. Conversely, they will be punished by losing part of their stake if they attempt to attack the network, go offline, or fail to validate the network. Ethereum 2.0 represents a fundamental change in how the Ethereum blockchain works. The BTC proponent Tuur Demeester shared the paper on Saturday and two quotes from the paper that theorize how an adversary can attack the chain.
Bitcoin proponents often criticize Ethereum’s level of centralization and ease of mutability. Ethereum proponents often defend it as necessary to change it into something better, to update faster. It’s a different set of philosophies, but it’s important to realize how different those philosophies are in the technical sense. Bitcoin Cash is a well-known example; they significantly increased the block size compared to the original Bitcoin protocol, and went in their own direction, and subsequently lost a lot of value compared to Bitcoin. Bitcoin Satoshi Vision forked out of Bitcoin Cash and subsequently lost a lot of value compared to Bitcoin as well.
A lot of people offhandedly propose proof-of-stake as being superior or better technology than proof-of-work, and praise higher-throughput systems, without realizing these technical issues at all. Many of the things they think are bugs to be eliminated from the system, like the fact that a proof-of-work system has a real-world resource cost, are actually features that make it as secure as possible. In contrast, a PoS node operator, even with the correct software downloaded, will regularly need to reach out to trusted third parties to ensure he stays on the canonical chain. The fear of losing contact with the main network & getting tricked onto the wrong chain will continue for eternity, possibly long after the trusted third parties cease to exist!
Protocol Or Operating System?
Indeed, for him, Ethereum’s implementation of PoS “excels” with regards to the aforementioned categories of decentralization, security, and fairness. When you submit a transaction on a shard, a validator will be responsible for adding your transaction to a shard block. Validators are algorithmically chosen by the beacon chain to propose new blocks. Crypto exchanges with numerous coins have an incentive to get you excited about new coins, because they make money from trading volumes.
Processors use random guesses to solve the puzzle left by the prior block, but the law of large numbers is such that the more bitcoin mining equipment you have, the more blocks you find over a sufficiently long period of time. The Bitcoin network is programmed to create a new block on average every ten minutes and add that block to the blockchain, which consists of hundreds of thousands of blocks since inception in 2009. There has been a bit more institutional interest in Ethereum, as well as institutional interest in follow-up chains like Solana, than I expected from January, so that’s something I’ve been monitoring. There is still a lot of regulatory uncertainty around these types of tokens; unlike Bitcoin they generally seem to meet the definition of being financial securities. I first stepped into the wondrous IT&C world when I was around seven years old.
Smart contract platforms with centralized attack surfaces can only exist at the pleasure of the government, so it comes down to how much regulatory crackdown they get vs how much regulatory approval they get. Ethereum’s proponents often criticize Solana as being too centralized, as their key defense for why Ethereum is better than Solana. But that puts Ethereum in a tight spot, because Ethereum’s proponents then have to criticize Solana as being too centralized, while also defending the fact that Ethereum has these centralized attack surfaces and greater complexity compared to Bitcoin. In other words, it has to justify what the right level of partial-centralization and partial-decentralization is, and that it has achieved this sweet spot. In bull markets, and at times with no regulatory crackdowns or drama, technical details don’t really matter.
Ethereum Pos Move Is Now Being Tested On A Mainnet Shadow Fork
An escrow multi-sig platform, for example, can serve as an independent third party. Buyers and sellers can enter into a 2-of-3 multi-signature contract online, where the seller puts in their bitcoins, and they only get released when the payment from the buyer is made. A third party holds the third key of that contract, which ensures the bitcoins are only released if both parties are happy, and can be an arbiter of disputes to accept proof if one of the parties is unhappy, before finalizing the transaction. There is also a third category, decentralized autonomous organizations or “DAOs” that have gained a lot of press in recent months, even though they’re not on the financial scale of DeFi or NFTs yet. After the seeds of this disagreement were laid from the protocol’s inception, and with Satoshi Nakamoto long gone, it was from 2015 through 2017 that the blocksize war went into full conflict. The Ethereum network has also operated via proof-of-work since its inception in 2015, but has been planning to change to a proof-of-stake system for several years.
It’s the idea that anybody who is continually online is always safe, because they are monitoring the chain and they always know what the correct chain is. There are rules about how frequently these checkpoints need to be produced, how we can rely on them, and we are building “somewhat trustless” mechanisms for getting hold of these checkpoints. It is, I understand, a deep clash with Bitcoin ideology in that sense that anybody in vacuo should be able to sync up from genesis and know they are on the right chain without trusting anybody in any way, shape, or form. That seems to be very difficult with proof-of-stake, that’s a compromise we made, but we believe in practice this is completely workable and will not lead to any practical attacks of any sort. A new block is produced by a bitcoin miner contributing processing power to solve a cryptographic puzzle that the previous block created, at which point the miner can package thousands of bitcoin transactions currently in the queue, into that block.
Seeing as how both intentional and unintentional hard forks happen with Ethereum quite often, that’s a relevant fact. It doesn’t mean it would resist every challenge but with this event, it has withstood a far bigger challenge to its decentralization model in the field than any other cryptocurrency. Once stablecoins are issued, people can then use whichever blockchain they are issued on to send and receive stablecoin payments between themselves with no centralized third party. From a user standpoint, stablecoins are a significant technological leap over existing bank payment systems, especially for international payments of any size, or large domestic payments. You can send someone a million dollars on another continent at 2am on a Sunday night and they can receive it in minutes, and you can verify the transaction on the blockchain.
And importantly, I separate technical price action from fundamental soundness, because they can be very different things for periods of time. This article touches on blockchains like Ethereum and Solana, but more broadly is about the centralization problems of proof-of-stake blockchains and custodial stablecoins in general, as the topics discussed here can apply to many blockchains outside of Bitcoin. The actual merge, slated for later this year, will replace the existing energy-intensive proof-of-work mechanism currently used to validate Ethereum transactions.
Bitcoin Follows Blue Chips South Amid Market Turmoil
These coins consistently failed to hold even 5% of Bitcoin’s market capitalization. The wisdom of the market has decided over rather long periods of time now that it’s not interested in them, at least outside of niche circumstances. If you and I meet in person, I can agree to send you a fraction of a bitcoin from my bitcoin address to yours, in exchange for cash or any other good that you hand to me, and we can do it at a coffee shop.
Trying to copy Bitcoin would be like if I copied the content from Wikipedia and hosted it on my website. It wouldn’t gain the real Wikipedia’s traffic, because it wouldn’t have the hundreds of millions of links pointing to it from other websites. And it wouldn’t be updated like the real Wikipedia, because there’s no way I could convince the majority of those volunteer editors to come work on my version instead. Unless I could somehow succeed in the herculean task of convincing the majority of the network to move over to my version, it would always just be a shadow of the real one with a tiny fraction of the value.
As a result, smart contract platforms remain in the midst of a “Layer 1 war” with each other, as they battle for market share. NFTs include things like digital art, unique game items, or digital movie tickets, that exist as unique items on a blockchain. Digital art, for example, doesn’t actually exist on the blockchain, but rather there is a pointer on the blockchain that links to where the image is stored elsewhere.
