ZK-focused Manta Pacific opts out of OP Stack for Polygon CDK

Manta Pacific’s ZK-application-focused network will integrate with the Polygon ecosystem through the Chain Development Kit software.

Manta, a blockchain network focusing on zero-knowledge (ZK) applications, will migrate its software from OP Stack to Polygon CDK, according to an October 16 announcement. This means that Manta will not be integrated into the upcoming Optimism Superchain and will instead become part of the Polygon ecosystem.

Manta network is an Ethereum layer-2 focusing on zero-knowledge-based applications, including digital identity and privacy solutions. It launched a mainnet on September 12 and has processed more than 500,000 transactions.

Manta was originally developed as an optimistic rollup that uses the OP Stack software developed by Optimism Labs. This software is intended to help create a “Superchain” of interconnected networks that will share the same security model. However, it faces competition from the Polygon Chain Development Kit (CDK), which employs a different security model but is also used to create a web of interconnected blockchain networks.

In its announcement, Manta said it chose to migrate to Polygon CDK for three reasons. First, with Polygon CDK, deposits and withdrawals can be processed quickly, as they don’t require a period of time for fraud proofs to be submitted. “Finality can happen in minutes or seconds, rather than days,” the announcement stated. This is because “CDK leverages the security of math rather than the social-economic incentives of fraud proofs.”

Secondly, Manta claimed that Polygon CDK is more “modular” and “sovereign” than alternatives, giving the team more flexibility as it continues to build out features. Thirdly, using Polygon CDK will allow developers to create a “trustless ZK bridge to Ethereum.” Over the long run, this bridge will allow users of different Polygon CDK networks to access each other’s liquidity, making the network part of a larger ecosystem.

The Polygon ecosystem originally consisted of just the Polygon Proof of Stake network. On March 27, the Polygon team launched a second network, Polygon zkEVM. In June, they announced plans to integrate these two networks into a new ecosystem called “Polygon 2.0.”

The Optimism ecosystem added a second network on August 9, as Coinbase launched Base network. On October 3, the Optimism team launched a fraud-proof system that's intended to be used throughout its ecosystem.

Polygon (MATIC) rally comes to an end as competitors devour market share

MATIC price has retraced a majority of its recent gains. Cointelegraph explores why.

Polygon’s native token (MATIC) experienced a 16.4% rally that coincided with the launch of Polygon 2.0 Goreli testnet on Oct. 4. However, the resistance at $0.60 proved stronger than anticipated and was followed by a 10.6% decline over the six days leading into Oct. 10.

This decline was exacerbated by negative news regarding the departure of a key co-founder and weak activity in Polygon’s zero-knowledge rollup (ZK-rollup) subnet.

MATIC’s price has wiped out previous gains from the early October rally, erasing the bullish momentum driven by the expectations of the protocol’s upgrades.

Rallies tend to follow mainnet and protocol updates

Polygon 2.0 is a network of ZK-based layer-2 chains unified via a novel cross-chain coordination protocol. Polygon’s 2.0 scaling technology was unveiled in June 2023 as a plan for a scaling ecosystem consisting of four layers: staking, execution, interoperability and proving. Each of these layers contributes to creating an interconnected ecosystem of chains that facilitate secure, fast and highly cost-effective transfers.

Among the benefits of Polygon 2.0 are enhanced security and privacy through ZK-proofs, full compatibility with the Ethereum Virtual Machine (EVM) and instant cross-chain interactions without requiring additional security or trust assumptions. It’s worth noting that the project is continuing to develop its Zero-Knowledge Scalable Transparent Argument of Knowledge-based layer-2 solution, Miden.

One could argue that the recent 10.6% retracement merely reflects an adjustment to the overexcitement triggered by the testnet launch. However, other factors may have contributed to investors’ worsening sentiment toward Polygon. For instance, Polygon’s ZK subnet, zkEVM, has lagged behind competitors in activity and deposits.

Network data shows Polygon losing steam as new competition emerges

Metrics from Artemis, an on-chain data provider, reveal a significant disparity between Polygon zkEVM’s 6,210 active addresses compared to StarkNet’s 154,390 and zkSync ERA’s 239,810. A similar discrepancy exists when analyzing the number of daily transactions, with Polygon’s ZK-rollup also trailing competitors.

Taking a broader perspective on the total number of transactions and deposits in the Polygon network yields suboptimal results. For example, Polygon’s total value locked (TVL) stands at $756 million, according to DefiLlama, which is less than half of Arbitrum’s layer-2 scaling solution.

It’s noteworthy that despite being launched much earlier than most Ethereum layer-2 solutions in June 2020, Polygon is now facing direct competition from Optimism and Base.

The departure of Polygon’s co-founder, Jaynti Kanani, on Oct. 4 after six years with the project also triggered some degree of discomfort among investors, given the project’s proximity to the crucial completion of its improved multiple-layer scalability solution. Interestingly, this decision follows the departure of Polygon Lab’s CEO, Ryan Wyatt, in July 2023, not long after joining the company in February 2022.

Further impacting MATIC’s performance was a decline in the number of active addresses using the Polygon network’s decentralized applications (DApps).

On average, the top 12 DApps on the Polygon network experienced a 17% decline in the number of active addresses over the last 30 days. This issue was particularly concerning in the NFT and decentralized finance markets, notably affecting applications like Uniswap, OpenSea and Move Stake.

Regardless of the reasons behind MATIC’s token surge earlier in October, the recent 10.6% negative performance can be attributed to reduced network activity, the departure of a co-founder during a critical upgrade phase and stiff competition from other ZK scaling solutions.

Ultimately, there is enough bearish news flow to justify this correction, although the team has been consistently delivering the necessary updates and improvements to the Polygon network. Investors should closely monitor the project’s progress in addressing these challenges and capitalizing on the innovations of Polygon 2.0.

Optimism network launches testnet fault-proof system in pursuit of decentralization

OP Labs implemented its modular fault-proof system on the OP Goerli testnet.

OP Labs, the developer of the Optimism network, launched a testnet version of its fault-proof system, according to an Oct. 3 blog post. Once it completes testing, it will allow for “a more decentralized and efficient Superchain,” the post stated. The new system is currently deployed to the Optimism Goerli network.

Currently, OP Stack-based networks use centralized sequencers to bundle transactions and submit them to Ethereum. Users cannot submit fraud proofs to block the sequencer if it submits incorrect data, creating the possibility of fraudulent transactions being confirmed if an attacker can control it. L2Beat has warned of this risk in its report on Optimism, stating, “users need to trust block Proposer to submit correct L1 state roots.”

OP Stack-based networks like Optimism and Base are intended to be optimistic rollups — a type of layer 2 that relies on Ethereum for its security. In a January 2021 essay, Ethereum co-founder Vitalik Buterin argued that optimistic rollups must allow users to submit fraud proofs to block fraudulent withdrawals to Ethereum. Otherwise, they’re not truly decentralized.

In November 2022, Buterin claimed that some rollups could have “training wheels” that keep them temporarily centralized while they work on a fraud-proof system but argued that they should work toward decentralization.

OP Labs claims the new fault-proof system will help fulfill the goal of decentralization for OP Stack networks: “The system is designed to eventually enable secure bridging without central fallback.”

In addition, it claimed the new system is modular, allowing each network to develop its own system for preventing fraud. It consists of three separate components: a fault-proof program (FPP), a fault-proof virtual machine (FPVM) and a “dispute game protocol.” Because these three components can be implemented separately, it opens up the possibility for each network to “custom-build a fault proof system.”

According to the post, this will create more diversity in the Optimism Superchain, ultimately making the whole ecosystem more secure. A network could even decide to use zero-knowledge proofs (ZK-proofs) as a type of fraud-proof, the team stated. ZK-proofs are generally utilized in zero-knowledge rollups, but not Optimistic ones.

OP Labs has been trying to build an interconnected web of blockchain networks called the “Superchain.” To accomplish this, it created the OP Stack, a set of software tools that can be used to create custom blockchain networks. Avail network has created “OpEVM” software designed to accomplish the same objective while using Avail as the base layer instead of Ethereum. Polygon’s ZK Supernets and zero-knowledge Ethereum Virtual Machine Hyperchain are other examples of Superchain competitors.

MetaMask ‘glitch’ caused opBNB recommended fees to be too high: Report

According to BNB Chain, MetaMask was averaging recommended fees from multiple networks, causing opBNB recommended fees to be too high.

A "glitch" in MetaMask that caused it to overestimate opBNB gas fees has now been fixed, according to a social media post from BNB Chain. Many users pay the default recommended fee displayed in their wallets, so a misestimation can cause users to overpay.

opBNB is an optimistic rollup layer-2 of Ethereum. It was launched on Sept. 13 and was developed by the team that created BNB Chain. According to the team, they discovered recently that “Metamask had set a default minimum recommendation price for gas based on the average of all networks.” This was a reasonable policy for other L2 networks, the team said, but it “didn't quite align with opBNB.” The team claimed that opBNB fees “can be much lower than other L1 and L2 networks,” making the estimation inaccurate.

Related: Hashing It Out podcast: What does the future hold for BNB Chain?

To solve this problem, BNB Chain contacted the MetaMask team, who were “extremely helpful and agreed to update their algorithm.” As a result, the wallet now accurately displays the network’s fees.

According to the BNB Chain team, users can now check each network's fees by switching to opBNB from within MetaMask and attempting to perform a transaction, which they say will prove that the network often has lower fees than competitors.

opBNB was developed using the OP Stack, a modular framework that can be used to create interoperable blockchain networks. The OP Stack was developed by the OP Labs team, which is attempting to create a “Superchain” comprised of multiple interconnected blockchain networks. The Superchain faces competition from Polygon's "Supernets," which attempts to accomplish a similar aim.

Google Cloud adds 11 blockchains to data warehouse ‘BigQuery’

Google’s BigQuery added 11 new public datasets for blockchain networks, allowing users to obtain a variety of data from these networks.

Google Cloud’s BigQuery service just added 11 blockchains networks to its data warehouse, according to a September 21 blog post. The new networks include Avalanche, Arbitrum, Cronos, Ethereum Görli testnet, Fantom, Near, Optimism, Polkadot, Polygon mainnet, Polygon Mumbai testnet, and Tron.

BigQuery is Google’s data warehouse service. Enterprise firms can use it to store their data and make queries of it. It also provides some public datasets that can be queried, including Google Trends, American Community Service demographic information, Google Analytics, and others.

In 2018, Google launched a Bitcoin dataset as part of the service, and later that year, it added Ethereum as well. It continued to expand its blockchain coverage in February of 2019, adding Bitcoin Cash, Dash, Dogecoin, Ethereum Classic, Litecoin, and Zcash. The September 21 announcement means that BigQuery now carries data from a total of 19 blockchain networks.

In addition to adding these new blockchains, Google has also implemented a new feature intended to make blockchains queries easier to execute. Through a series of user-defined functions (UDFs), the team has provided methods to handle the long-form decimal results often found on blockchains. In its post, Google claimed that these new functions will “give customers access to longer decimal digits for their blockchain data and reduce rounding errors in computation.”

Google Cloud has been taking an increasing interest in blockchain tech in 2023. On July 7, it partnered with Voltage, a Lightning Network infrastructure provider. And it partnered with Web3 startup Orderly Network on September 14 to help provide off-chain components for decentralized finance.

USD Coin officially expands to Base and Optimism networks

Circle’s USDC is now available natively on Base and Optimism, and Coinbase accounts can transfer the stablecoin to Base for the first time.

Circle’s USD Coin (USDC) has launched natively on both Base and Optimism networks, allowing Circle account holders to send USDC stablecoin from their accounts to Base or Optimism. Coinbase has also made USDC transfers to Base available, according to a Sept. 5 social media post. Circle claimed that it is working with “ecosystem partners” to develop a system for users to swap old, bridged versions of USDC for the new, official versions.

Coinbase’s Base network launched on Aug. 9. But at launch, Coinbase users could not send USDC to the Base network from their exchange accounts, nor could Circle account holders. Base users relied on a bridged version of USDC, called “USDbC,” to make U.S. dollar transactions. On Aug. 29, Circle CEO Jeremy Allaire announced that a native version of USDC would be made available “next week,” but no specific date was given.

The Sept. 5 announcement states that the coin is now available natively on Base. On the same day, the Coinbase interface started showing an option to transfer USDC to Base.

Despite this official launch, many decentralized exchanges on the network continue to use the old version of the coin. At the time of publication, Uniswap, Baseswap, Aerodrome, Maverick, and other DEXs continue to show the old contract address when users select the stablecoin.

The announcement stated that USDC has also been launched on Optimism, providing a replacement for the USDC.e token that was previously used on the network. As with Base, Optimism DEXs do not appear to have been integrated with the new version yet.

Circle has been attempting to fight back after its stablecoin lost market share to Tether (USDT) throughout early 2023, but it also faces increasing competition after the launch of two new stablecoins during the summer. First Digital USD was launched in June, and Binance began promoting it in August. PayPal also launched its PYUSD stablecoin on Aug. 7.

Base, Optimism unveil shared governance and revenue-sharing framework

The two networks will share profits and governance using multisignature wallets, and a “security council” will be formed as the ecosystem grows.

Developers behind the Base and Optimism networks have jointly announced a revenue-sharing and governance-sharing agreement. Coinbase, the parent company of Base, has also published a list of “principles of neutrality” it will follow to prevent Base from becoming centralized. This announcement was made through three separate blog posts on Aug. 24: one from the jointly controlled Optimism Collective, one from Base and one from Coinbase.

According to the Optimism Collective’s post, Base’s smart contracts can only be upgraded via a two-of-two multisignature wallet account. One signature is controlled by Base and the other by the Optimism network’s team (called the “Optimism Foundation”). This means that Base cannot be upgraded without the consent of the Optimism team. As more chains opt to use the OP Stack and become part of the “Superchain,” governance will be handed over to a “security council” with representatives from all of the chains that comprise this ecosystem.

Base will also pay either 2.5% of its revenue or 15% of its profits to the Optimism Collective, whichever is greater. In return, it will receive “up to approximately 118 million OP Tokens,” allowing it to have a voice within Optimism’s protocol governance. This amount will be capped at 9% of the total votable supply in order to maintain balance, the announcement stated.

The post from Base was issued under the name of its principal creator, Jesse Pollak. He pledged that Base will become more decentralized over time, moving from what Ethereum co-founder Vitalik Buterin called “stage 0” to “stage 2” of a layer 2’s decentralization. The Base team will work to improve the scalability of the two current Optimism clients, op-geth and op-node, and create an entirely new client called “op-reth” to diversify the types of clients used.

The team will also continue to develop Pessimism, a real-time network-monitoring tool that attempts to detect cybersecurity threats early.

In addition, Pollak confirmed that Base will share revenue with the Optimism Collective and will eventually hand over upgrade keys to an Optimism security council.

Coinbase’s post was published under the name of the company’s engineering lead, Will Robinson. He focused specifically on the concept of “neutrality.” 

Robinson pledged that Coinbase will remain a neutral participant in the Base network. The exchange will not “custody or control the crypto that users bring to the Base network,” nor will it change the order of transactions for its own benefit or “misuse any non-public information gleaned from Base.” 

Robinson claimed that Coinbase’s marketing team and other branches of the company will use only publicly available data from block explorers and other tools in its efforts to sell Coinbase’s products, gaining no insider advantage from running Base’s sequencer. Withdrawals from Base will also be processed without censorship, respecting what Robinson calls “freedom to exit.”

Some critics of the Base network have suggested that its currently centralized nature may lead to regulatory scrutiny from the United States Securities and Exchange Commission. For example, attorney Gabriel Shapiro has stated that Base “could threaten dangerous collateral damage” to the industry. 

Coinbase CEO Brian Armstrong also raised eyebrows on March 7 by suggesting that “centralized players” on Base must implement identity verification. Despite these criticisms, many Ethereum investors have expressed hope that Base and the Optimism Superchain will help to onboard new users to the Ethereum ecosystem.
