Proof of Reserves (PoR) To Avoid Future CEXs From Liquidation

Proof of Reserves (PoR) To Avoid Future CEXs From Liquidation

Binance and other big centralized exchanges plan to use the Proof of Reserves as an auditing technique to reassure their customers of the safety of their funds.

As trust in its accounting of billions in assets disappeared, crypto exchange FTX went bankrupt at the beginning of November 2022.

Some critics have slammed the existence of centralized exchanges, such as FTX. Its CEO, Sam Bankman-Fried, posted many messages on Twitter trying to convince his customers that he had made a terrible but honest mistake that he would try to repair. However, CEX customers are now all wondering just how safe their assets are on any of these exchanges. And the truth is that without total transparency from the exchanges, the FTX collapse could happen again at any given time.  

The controversy has brought back the debate about a possible solution. It is called proof of reserves, or PoR. This method shows, without any doubt or ambiguity, how many tokens are on each exchange that uses the technique. Proof of reserves, if in place at FTX, could have, in theory, stopped customers’ money from being moved to places it shouldn’t. In this case, the assets wouldn’t have moved to Bankman-Fried trading firm Alameda Research.

Binance, the largest cryptocurrency exchange in the world by volume, has shared its wallet accounts and said it would conduct a proof of reserves snapshot within the next few weeks. Other CEXs that made similar statements include Gate.io, KuCoin, Poloniex, Bitget, Huobi, OKX, Deribit and Bybit

What is proof of reserves?

Proof of reserves is an audit technique that confirms assets in custody. It is used by stablecoin issuers Paxos to show they have enough assets backing their tokens. Exchanges like BitMEX use the technique to prove that customer deposits correspond with assets in custody.

Sergey Nazarov, the co-founder of Chainlinks Labs, stated that the use of this auditing solution could have made it possible to avoid all of this: “It would have been quite a solvable problem if there had been more transparency in the balance sheet.” Chainlink offers the proof of reserves (PoR) auditing mechanism as a product. Their PoR solution already powers multiple stablecoins and gold coins. 

How does proof of reserves work?

An entity can prove its assets reserves in a variety of ways. These include traditional third-party audits that are performed by companies such as Armanino, to Merkle tree proofs (cryptographic verification using data structures called Merkle branches).

There are also methods that blockchain analytics companies employ. Chainlink is an example of a company that separates proof-of-reserve implementation into two categories: on-chain and off-chain.

An off-chain alternative is a third-party provider, such as Chainlink, that receives API access (application programming interface) from an exchange. This allows the auditor or custodian to verify the exchange’s holdings.

Off-chain proof of reserves (Chainlink)

On-chain routing is a proof of-reserves smart contract on one network (usually Ethereum). It receives data feeds from Chainlink’s Oracle network (on a block-by-block basis) about a provider’s on-chain wallet balances in another network (e.g., Bitcoin). This empowers users and allows them to check whether the company or the exchange actually has the assets they claim to have.

Should proof of reserves be used?

Investment brokers that offer services to retail customers are already producing regular reports to show the client’s assets and liabilities. But this is done because of the harsher regulations that are already in place for them. For the most part, cryptocurrency exchanges remain unregulated financial services, and customers have nobody to lean on when it comes to a lack of liquidity or bankruptcy. 

A first step may be self-regulating services that may regain the trust of customers. Authorities might also be willing to adapt their regulations to the crypto industry when existing exchanges collaborate. 

Over the last few years, many exchanges have collapsed, causing crypto investors to lose a lot of money. While many never got their funds back, this also caused existing services to practice much better security and transparency.  

Crypto Exchange FTX Has Filed for Bankruptcy Protection in the US

Crypto Exchange FTX Has Filed for Bankruptcy Protection in the US

The Bahamas-based company, FTX.com crypto exchange, announced Friday (November 11, 2022) that the crypto exchange had filed for bankruptcy protection in the United States.

Sam Bankman-Fried, the founder and CEO of FTX, has also resigned but said he would assist with an orderly transition. John Ray III will be the new CEO. Ray seems to be the same person who oversaw Enron Corporation’s bankruptcy.

According to Ray, FTX employees will feel the pressure in the near future: “In the short-term, we have some long and hard work ahead.” He also described the bankruptcy filing as “the beginning of a journey forward.”

Respective bankruptcy filings stated that FTX US (and Alameda Research) had between $10 billion to $50 billion in liabilities, as well as a similar range of assets. They also estimated that the funds would be available for distribution to unsecured creditors.

Why did FTX collapse? 

This is the context that will help you understand this story. This includes the unexpected crisis of confidence caused by revelations about Sam Bankman Fried’s accounting practices, the shock at Bankman Fried’s reputation as a golden boy, and the complex role played by Binance and Changpeng Zhao, its founder in the crisis.

Let’s start with the background story of Sam Bankman Fried and his other company, Alameda Research, which played a major role in this series of unfortunate events. 

At the beginning of November 2022, Alameda was holding around $5.8 billion out of its $14.6 billion assets in FTT, FTX’s exchange token. 

Based on leaked documents, this finding was shocking because of the close relationship between Alameda & FTX. Both were established by Bankman-Fried. There has been considerable anxiety about the nature and extent of their fraternal relationships. This raises questions about the open-market, real-world value of FTT tokens that are held in reserve by affiliated entities.

Negative speculation about financial institutions can become a self-fulfilling prophecy. It can trigger withdrawals from a feeling of uncertainty and lead to liquidity problems. 

But simple facts can be enough to cause a bank run. FTX token and Alameda have a history of close ties. This led to a mass exodus on November 8th. According to internal messages, Reuters saw $6 Billion in withdrawals on the exchange before things turned sour. What’s more, at the time, FTX exchange has an internal balance of only 1 BTC. Meanwhile, the exchange’s bitcoin balance reached 36 BTC, but this is still minute compared to the half a million BTC held by Binance or Coinbase. 

Bankman-Fried’s team began to search for acquisition partners in a rush and approached a range of potential partners just before Binance was involved.

It is still unclear why FTX would want to be rescued even if there was such a rush for exits. Users were promised that the exchange would not speculate on cryptocurrencies in their accounts. If that policy had been followed, then there shouldn’t have been a pause in withdrawals or a balance sheet gap to fill. Coinmetrics analyst Lucas Nuzzi has provided evidence that FTX transferred funds in September to Alameda, possibly as a loan to cover Alameda’s losses.

Alameda’s vast FTT-linked assets seemed to confirm fears about the stability of Bankman-Fried. The token’s market value decreased by 90% between November 7 and November 10.

FTX announced that it had temporarily suspended all crypto withdrawals late in the evening on November 8, following the announcement of a tentative agreement with Binance.

According to a press release, the FTX.com entity, as well as FTX USA, Alameda Research, and “approximately 13 additional affiliated companies,” has filed for Chapter 11 bankruptcy proceedings. Chapter 11 bankruptcy proceedings can be filed by companies that hope or expect to be able to restructure their operations. This is in contrast to Chapter 7 bankruptcy which only liquidates assets.

Companies that file for Chapter 11 bankruptcy can continue to operate their daily operations.

Bankman-Fried posted a tweet after the bankruptcy and apologized. He said, “Hopefully things can find a way to recover. Hopefully this can bring some amount of transparency, trust, and governance to them.”

The release stated that FTX Digital Marketplaces, FTX Australia and FTX Express Payment are not included.

Ray stated that the FTX Group’s valuable assets can only be efficiently managed in an organized, collaborative process. “I want to assure every customer, employee, creditor, contract partner, stockholder, investor and other stakeholder that this effort will be conducted with diligence, thoroughness, and transparency.”

He said that events have been “fast-moving,” and the new team has just begun.

The FTX bankruptcy sent shockwaves on the crypto market

Bitcoin immediately plunged to $1,000 after the bankruptcy news and fell to $16,500 in just minutes.

Bankman-Fried reported FTX’s “liquidity” issues earlier in the week.

 Firstly, it was stated Binance had offered to purchase the company. Then, Justin Sun of Tron announced a deal to support TRX-based tokens. FTX halted withdrawals, but FTX US withdrawals remained unchanged. FTX announced that certain jurisdictions had initiated partial withdrawals.

According to a bankruptcy filing, the complete list of companies includes Alameda, various local holdings, and Blockfolio. Quoine and over a dozen FTX entities are also included.

“I was shocked to see that FTX listed BTC Africa S.A. and other AZA Finance entities today,” stated Elizabeth Rossiello in a statement. She is the CEO and founder of BitPesa as well as AZA Finance. To be clear, AZA Finance entities aren’t affected by the FTX bankruptcy. We are taking steps to rectify the erroneous court files,” she said, adding that “in its disorganized haste, FTX erroneously listed their entities in bankruptcy filings.” Here’s the AZA Finance statement regarding the FTX bankruptcy statement. 

The crypto market is interconnected

The collapse of the Three Arrows Capital hedge fund has shown that crypto is extremely interconnected. Evidence suggests that Alameda’s financial problems began after it lost half a million dollars to Voyager Digital. Voyager Digital was later purchased by SBF, as it had been insolvent after Terra collapsed.

Unfortunately, as more people are attracted to the crypto and blockchain space, they are drawn by big marketing campaigns to these massive centralized exchanges. the industry has re-created the centralized financial system, including “bank runs” and all. Instead of interfacing directly with peers and blockchains, people now store their money on centralized exchanges. Instead of trusting financial protocols that are not reliable, they place their faith in Wall Street-respected megalomaniacs.

The  Securities and Exchange Commission (SEC) also took notice of the FTX and has ongoing investigations. Gary Gensler, Chairman of the SEC, almost gloated about this moment, noting the “toxic mixture” at FTX. He repeated the familiar line that cryptos are securities and should be under his agency’s supervision. Gensler also noted that the industry had been “significantly non-compliant” and that exchanges should “come into and talk to us.” 

It is notable that FTX.US, the independent wing of SBF’s trading empire, seems to be solvent. It could all go down tomorrow, but it seems that SBF wouldn’t have done the same shenanigans using FTX.US user funds as he did with the parent company, no matter how tired he was.

Yet, it is important to mention the role that U.S. crypto regulation played in the FTX downfall. Coinbase’s CEO Brian Armstrong argued on Twitter that the stringent-yet-unclear regulatory landscape pushed people like Terra’s Do Kwon and Bankman-Fried overseas, where oversight is lax, and taxes go unpaid. According to Gary Gensler, 95% of crypto trading occurs outside the U.S.

Crypto may fail because it is not regulated

Cryptocurrency was created to allow people to be their own bank by allowing them to be independent and responsible for their finances. Instead, Three U.S. regulators – the Commodity Futures Trading Commission, the Securities and Exchange Commission, and the Department of Justice – have intensified their investigations into FTX. Some of these investigations had been ongoing for months.

In an interview with CNBC, Gensler may be correct in stating that there are rules that could protect crypto investors. Armstrong is protecting his interests here, while Sen. Elizabeth Warren (D.Mass.) and others are calling for tighter regulation. Gensler and Armstrong are calling for tighter regulation on U.S. exchanges. While more explicit regulations are essential, they must be followed. Because crypto is not a country-specific currency, regulators who make it too burdensome will only be able to create the next Terra-based in Singapore or Bahamas-based FTX. Armstrong said that it was absurd to punish U.S. companies like this.

Independent Blockchain Games Have More Users Than Top Metaverses

Independent Blockchain Games Have More Users Than Top Metaverses

The largest metaverses have lower daily active users than other smaller and independent blockchain games. Top metaverses are trying to make things appear better than they actually are. 

The metaverse received a lot of attention in 2021 when the concept of non-fungible tokens (NFTs) became the most controversial investment opportunity. Recently, people started to wonder what is the exact number of daily active users (DAUs) on the most popular metaverses. Decentraland and The Sandbox tried to explain how they calculate the users, but numbers don’t lie. 

According to DappRadar, the two most famous metaverses are lacking users. And people have started to notice that. 

Even if the numbers are a rough estimate, the DAU controversy raises serious concerns about online user behavior. And it suggests that online users are not quite ready to jump into the metaverse and exist there. While this wouldn’t be an issue with any random online game, having a metaverse that is literally worth over $1 billion in crypto is an essential aspect of the blockchain industry. 

Decentraland is an expensive but lonely metaverse

DappRadar is a data blockchain aggregator and tool that analyzes DApps on the main blockchains. Recently, DappRadar revealed that the Ethereum-based virtual universe Decentraland had 38 active users in the last 24 hours, while its competitor Sandbox had 522 active users in the same period.

The DappRadar tool has no way to determine the active users of any metaverse, but it can count the unique wallet address that interacts with the platform’s smart contracts. An example of active use is logging onto The Sandbox or Decentraland to make a purchase using SAND or MANA (each platform’s native utility token).

DappRadar doesn’t include people who log in to interact with others on metaverse platforms or drop by for events, such as concerts. This could also mean that there are fewer transactions on these platforms, from buying or selling NFTs than people who visit them.

According to DappRadar, an estimated 749 were active on November 1st, and this number never goes above 880 in the entire month of October. The tool counts around 5,850 wallet addresses that have interacted with the DApps’ smart contracts in the entire month of October 2022. While this number doesn’t tell us exactly the number of users, it is considered a way to track the “active users” per day on Decentraland.

WeMeta, a metaverse analytics tool, provides the average concurrent players, which can only give you the number of users on Decentraland servers at a specific time. This tool only counts around 600 daily users.

In contrast, DCL Metrics, an analytics platform built by the Decentraland community, offers an estimate of almost 8,000 of the number of unique users. 

As you can see, there isn’t a sure way to determine how many users are in the Decentraland metaverse every day, and the platform said that they are not counting them. 

According to Decentraland, they had over 56,000 monthly active users in September and about 1,000 users interacting with smart contracts. 

Take into account that Decentraland (MANA) is valued at $1.18 billion, according to CoinMarketCap.

The Sandbox is also struggling to attract users

Let’s look at Decentraland’s competing metaverse, The Sandbox, which has a token also evaluated at over $1.23 billion, according to CoinMarketCap. 

According to DappRadar, The Sandbox has about 2,160 UAW (Unique Address Wallets) active in a 24h timeframe that interact with the DApp smart contracts. 

Again, there is no tool to tell us the daily active users in The Sandbox, but WeMeta gives us a hint of the active traders in the SAND metaverse. As of November 1st, 2022, there were 117 traders in The Sandbox, while only 52 traders in Decentraland. 

The Sandbox also tweeted some of their monthly stats, which say that the metaverse has over 39,000 daily users. 

Independent blockchain game is more successful than these $1 billion metaverses

Aside from these heavily marketed metaverses, other blockchain games are indeed free to play and deliver an enjoyable experience to passionate gamers. One such example is FootballCoin, a fantasy football manager built entirely on their own blockchain. 

The game allows anyone to create an account and play the game for free, offering daily rewards. 

Without any dependency on any other chain, FootballCoin has around 1,000 active players. While this is not a metaverse, the game’s community is highly engaged on other communication platforms, such as Telegram and Discord, where they negotiate NFT trades and create joint competitions. 

According to CoinMarketCap, FootballCoin has a market cap of about $2,8 million and has an ascending trend. 

As with anything in the crypto space, people choose to invest their time into projects that offer value and potential future profits. 

A $57 Million Lawsuit Against Terra Co-founder Do Kwon

A $57 Million Lawsuit Against Terra Co-founder Do Kwon

Terra co-founder Do Kwon and others are accused of making fraudulent claims regarding UST, either knowing they were false and unverifiable or recklessly not caring if they were true or false.

Do Kwon is the co-founder of Terraform Labs. In May 2022, the Terra blockchain collapsed in only a matter of hours as its algorithmic stablecoin was strategically exploited. This left Terra investors liquidated, and many lost their life savings. After many months of controversy and accusations against authorities for not doing anything, the case is going to court.

Do Kwon may face legal action in South Korea and the United States. Do Kwon will also be sued in Singapore, along with the Luna Foundation Guard (LFG) and Terra’s other founding member, Nicholas Platias.

The lawsuit against Kwon Terra’s co-founder Do Kwon

On September 23rd, 359 people filed a lawsuit in Singapore’s highest court. According to their accusations, Kwon, Platias, and Terra made fraudulent claims. After the collapse of Terra’s stablecoin TerraUSD (UST), Do Kwon stated that they are creating a Terra hard fork, and that the old stablecoin is now TerraUSD Classic (USTC). What we all agree on is that Terra’s U.S. dollar peg could not be maintained due to its unstable design, which is basically a flaw of algorithmic stables.

The plaintiffs are asking for compensation for $57 million in “loss and damages” based on the UST tokens that they bought, held, or sold during the May market crash. They also ask for an order to cover “aggravated damages.”

The lawsuit claims that Terra and other parties related to it knew or should have known that the claimants wanted to purchase and hold stablecoins that would not be subject to volatility, and that could earn passive returns. The document is also indicating that Do Kwon’s experience in an earlier project (Basis Cash) would have made it impossible for him not to be aware of the structural weakness of algorithmic stablecoins. 

The main accusation is that Do Kwon and the other defendants made the fraudulent representations either knowing they were false and untrue or recklessly not caring if they were true or false.

Terraform Labs spokesperson for Terraform Labs stated that both LFG and the company are trying to protect themselves from the claims:

“There is a fundamental difference between a public market event and fraud. Terraform Labs and the Luna Foundation Guard committed no wrongdoing — the risks were publicly known and discussed, and the underlying code was open-sourced.”

What happened to Do Kwon after Terra’s collapse?

Since the May collapse of Terra’s blockchain ecosystem, Kwon has been subject to numerous legal actions and threats. In September, South Korean authorities issued an arrest warrant for Terra co-founder, but it was later dismissed. Interpol also added Kwon to its Red Notice List, asking law enforcement to locate him and possibly detain him.

Since Do Kwon is a Korean citizen, the South Korean foreign ministry demanded that the Terra co-founder surrender his passport. Otherwise, it would be canceled. On Oct. 6, the Ministry of Foreign Affairs in South Korea issued an order to Do Kwon, Terraform Labs CEO, to surrender his passport.

Within 14 days of receiving the order, the fugitive cofounder must turn over his Korean passport. Refusal to comply with the order will result in his passport being canceled, and any future requests to reissue it will be rejected.

Another local report stated that six Terraform Labs employees, including Kwon, received a passport return order.

Kwon was active on social networks during the controversy. He stated in September that he was making “zero effort to hide” his location despite not disclosing it. In response to the lawsuit, it stated that Kwon was “doing an awful job of acting innocent for someone who is innocent”. Many others speculated that Kwon had undergone plastic surgery to hide his appearance.

Kwon was listed as residing in Singapore by the Sept. 23 lawsuit, although some reports suggest that he could have fled the country. His current location is unknown.

Terraform Labs claimed the case against Kwon was highly politicized. According to a spokesperson for the company, prosecutors agreed to expand the definition of security following the collapse of associated cryptocurrencies.

Terra investors are also on the lookout for Kwon

A Discord group of over 4,400 people has created the UST Restitution Group (URG). This Discord group has been trying to find Terra co-founder Do Kwon.

The group uses the internet to find clues and share them with one another to locate Kwon. This may be done out of frustration at not receiving any results from law enforcement agencies.

Some members suggested he could live in Russia, Dubai, Azerbaijan, or even on a yacht.

They continue to work despite South Korean authorities taking significant steps to bring Kwon justice. 

URG was initially formed on May 16th as a chatroom for Terra ecosystem investors. Some members are claimants in lawsuits to recover funds from TerraUSD Classic (USTC).

New EU Rules for Crypto Exchanges and Russian Users

New EU Rules for Crypto Exchanges and Russian Users

Many popular crypto exchanges have stopped operating in Russia. However, some platforms continue to serve the region.

Nine months after the conflict between Russia and Ukraine, sanctions against Russia have grown at an aggressive rate. The European Union legislators announced that they would ban all cross-border crypto payments between Russia’s citizens and Russia.

The EU has initiated a ban on all “crypto asset wallets and accounts” in response to Russia’s continued annexes of Ukrainian land, its repeated mobilization of troops in the country, and threats of nuclear escalation.

In previous sanctions, cryptocurrency payments between Russian and EU wallets were limited to 10,000 euros. This new ban will deprive Russia of its military power and limit its industrial components.

Crypto exchanges apply bans on Russian crypto users

A number of popular cryptocurrency exchanges in the region, including LocalBitcoins and Crypto.com, sent emails to customers advising them to withdraw funds immediately to avoid being unable to use their services.

It’s worth noting that in September 2022, LocalBitcoins was responsible for 8% of Russia’s crypto trade volume. This makes them the largest client base on the exchange. Additionally, Russian users were responsible for facilitating 20% of all BTC trading volumes before the ban.

Binance, the largest cryptocurrency exchange in the world, is working to implement the new restrictions. A representative of the firm said that the changes could take time and would not be live until a set date. 

Bitfinex, an exchange that had opposed the increasing sanctions being imposed against Russian citizens, has recently changed its mind, saying that it may need to modify its policies if directed by the regulatory authorities.

Another ban faced by Russian citizens comes from Dapper Labs, who banned them from accessing the popular blockchain earlier this month. Users from this side of the globe will not be able to access the popular NFT marketplace, along with several other crypto products.

The ban’s impact

It’s no surprise to anyone that most Russians can’t rely on their bank accounts anymore, and crypto provides a safe haven to guard their savings or receive money from abroad. The hard fact is that digital assets can be used to help citizens in war zones. And it’s the same with Ukraine, which has received billions in crypto donations. 

This last ban will cause pain to some Russian financial institutions and retail outlets. The fact that BTC saw a sharp increase in price during the conflict is something that the EU is much aware of. The European Authorities noticed this loophole in their strategy of suffocating Russia, and it’s also trying to sanction this.

However, these sanctions will be enforced through the EU’s Financial Action Task Force, and they can potentially redefine the region’s crypto landscape in the near future.

What happens to Ruble pairs that are held by these exchanges

The regulators have been strict with exchanges that allow blacklisted citizens to trade on their platforms in the past. This leads to the question: What will large volumes of Rubles trading pairs do when dealing with these assets? 

Nobody gave any indication of what exchanges should do, and they will be prudent this time. Now, the exchanges have no choice but to make major losses on their balances. The ban will put decentralized finance (DeFi) back in the spotlight because it provides a censorship-resistant and easily accessible infrastructure to people living in geopolitical turmoil. However, we’re already seeing censorship on the new PoS Ethereum blockchain.

It is unclear if exchanges will have to return funds to Russian users or block access to their accounts. This is something that each exchange will have to resolve on its own. 

Despite the ban, many exchanges are still functional

Binance is considering restricting its services to Russian users. However, Binance is operating as usual. The United States-based exchange Kraken, which is based in the United States, has not placed any restrictions on Russian customers, and there are no indications as to whether it will voluntarily comply with EU requirements.

Antigua and Barbuda’s FTX is another popular exchange that has not been subject to any kind of ban. Garantex, a popular Russian cryptocurrency platform, has not been banned. It still offers traders in the region a variety of advanced services like futures and derivatives.

Other popular platforms operating in the region include Seychelles-registered Huobi Global, OKX, KuCoin, and Mexc Global. Bybit, a Singapore-registered cryptocurrency exchange, stated that it would continue to adhere to its ethos and support transparency, freedom and decentralization. It will not impose sanctions on Russian clients. Many of these clients may not agree with the war or the stance of their leaders.

Last but not least, Exmo, a crypto exchange based in the United Kingdom, has sold its Russian business earlier this year to a local vendor. Its Exmo.me domain still allows the platform to operate in Russia and the neighboring countries of Belarus and Kazakhstan.

As the war between Russia and Ukraine continues, it will be fascinating to see how crypto companies operating in the region adapt and adjust to changing geopolitical realities.

Ethereum Centralization: Who Is Censoring ETH Transactions?

Ethereum Centralization: Who Is Censoring ETH Transactions?

The Ethereum Merge was completed one month ago. Since then, Ethereum centralization has been on the rise. More and more Ethereum nodes have been censoring the network. As of October 2022, 51% of Ethereum blocks were compliant with OFAC standards, which are meant to censor Ethereum’s blockchain. 

What is OFAC?

OFAC, or Office of Foreign Assets Control, is a U.S. Treasury Department financial intelligence and enforcement agency. It enforces trade and economic sanctions to support U.S. foreign policy and national security objectives.

In August 2022, the crypto community was first acquainted with this agency when they issued a statement to sanction blockchain activities. It effectively sanctioned Tornado Cash as well as several Ethereum addresses that were associated with it.

Today, the number of nodes that are validating OFAC-compliant blocks is on the rise, and this represents a significant step towards censorship as more blocks are being monitored. 

The current state of compliant MEV-boost relays can be verified on mevwatch.info, a free tool built by Labrys. 

MEV-Boost relays are centralized entities that act as trusted mediators between block builders and block producers. This allows all Ethereum proof of stake (PoS) validators to outsource their block productions to other builders.​​​​​

This metric shows how many blocks have been built since the Merge by OFAC-compliant MEVBoost relays. MEV-Boost was able to provide a more representative distribution for block proposers than a small number of miners who are proof-of-work (PoW) after Ethereum upgraded to a PoS consensus.

How is the OFAC involved with the Ethereum blockchain?

After “The Merge” upgrade was completed, the Ethereum blockchain started using the proof-of-stake (PoS) consensus mechanism. This made the blockchain more secure and energy efficient. Mining data shows that Ethereum heavily relies on Flashbots, a single server, to build blocks. This raises concerns about a single point of failure for the blockchain.

What is Flashbots? Flashbots is a network that connects mining pools and searchers. It’s not a closed system that uses private contracts or arrangements. Instead, anyone can join. Because it allows for competition, this open system is thought to be more beneficial than having a few dominant private entities. It acts as a relay to deliver Ethereum blocks. Data from mevboost.org indicates there are seven active relays currently delivering at most one block in Ethereum. These include Flashbots, BloXroute Max Profit, BloXroute Ethical, Blocknative, Manifold, Eden and BloXroute Regulated. 80% of MEV-Boost blocks are relayed by Flashbots.

Ethereum Centralization: Who Is Supporting Centralization on ETH Transactions?

What is Ethereum centralization? How can ETH transactions be censored?

Hard censorship would mean that no matter how long or how expensive you pay, sanctioned transactions will never be included in the blockchain. In a strict censorship scenario, compliant nodes would be required by regulation to discard all blocks with any of these transactions.

However, even with soft censorship, when approved transactions are eventually validated, it would likely lead to long waits, high-priority charges, and a substandard user experience.

Out of the seven major MEV-boost relays currently in operation (Flashbots, BloXroute Max Profit, BloXroute Ethical, Blocknative, Manifold, Eden, BloXroute Regulated), only three do not censor in accordance with OFAC compliance requirements. For instance, OFAC-compliant relays won’t include transactions that interacted with Tornado Cash smart contracts or other sanctioned wallet addresses, as defined by OFAC.

Validators that wish to include all network transactions can do so by not including any censoring relays in their MEV-boost configuration. Current major MEV-boost relays that don’t censor include – BloXroute Max Profit, BloxRoute Ethical, and Manifold.
