This is our submission to the great Reddit Scaling Bake-off 2020.
It’s a StarkEx Rollup (data on-chain).We did it in 1 proof, 300K transactions, 3,000 TPS, 315 gas / transaction on Ethereum mainnet.
To watch our demo and read our detailed explanation of how we did it - see our post:
Dear Reddit,This is our submission to The Great Reddit Scaling Bake-off. It’s a StarkEx Rollup (data on-chain).
Show & Tell
Our DeckIs here
Table of ContentsStarkEx — General
The StarkEx engine has on-chain and off-chain components. Generally speaking, off-chain is for heavy-duty computation and storage, while on-chain is for the computationally-lean verification , state commitment, and data-availability required for using the escape hatch.
For a more detailed overview read our medium post. Note, however, that this post describes StarkEx in Validium mode (off-chain data), whereas in this bake-off we demonstrated StarkEx in Rollup mode (on-chain data).A note on terminology: Rollups using cryptographic proofs are often called “ZK-Rollups” even when the proofs are not Zero-Knowldge (ZK); we shall use this common term when referring to the general class of proof-based Rollups.

StarkEx Demo for the Reddit Bake-off
There are two sets of costs in a StarkEx system:
In the bake-off, the actual on-chain costs were 94.47M, (average of 315 gas per Tx) and the off-chain costs were negligible in comparison (less than 5% of on-chain cost).
At a gas cost of 70 gwei, this cost us 6.6 ETH, which at an ETH price of $230 cost $1,518 (average on-chain cost of ¢0.5 per bake-off Tx). Naturally, the USD price fluctuates with the price of gas on Ethereum, and the price of ETH.
94.5% of on-chain costs were due to operating in Rollup mode, i.e. for posting the transaction data on-chain (section 1.b above). Had we run the same in Validium mode, the on-chain costs would have been a mere 5M gas (average of under 17 gas per Tx), and would have cost 0.35 ETH, which translates to a total of $80.5 (average of ¢0.02 per bake-off Tx).
On-Chain Gas Consumption Summary:
With StarkEx, the verification cost grows only poly-logarithmically with respect to the batch size. This is displayed most clearly in Validium mode, where data is not posted on-chain, and thus on-chain cost scales sub-linearly (logarithmically) with batch size. Consequently, at high scale, the amortized on-chain cost of a single Tx in Validium mode goes to zero with batch size, and the off-chain cost dominates. In terms of off-chain cost, STARKs have a significant advantage over SNARK-based solutions: latest state of the art STARK provers are 20x faster than state of the art SNARK provers and this speedup is based on fundamental cryptographic reasons¹.
In general, the actual cost depends on various factors, including:
Note that the costs quoted above are the actual variable costs for running the bake-off on Mainnet. We have read various publications from competing scaling solutions quoting costs that are merely estimates, and often neglect significant parts of the actual cost structure, as typically they don’t yet have a fully functional product. As far as we know, STARK (as a cryptographic protocol) and StarkEx (our specific implementation for this use case) are significantly more efficient than other cryptographic proof systems. For example, ethSTARK, our EF-funded open-source code, is 20X faster than any other proof system we know of. This efficiency translates to a cost advantage over other alternatives, when all considerations are taken into account.
Minting is done by transferring Points from the moderator accounts to chosen users (per Reddit’s specification, users claim these Points). This is done via the Moderator API.
UX — Subscribe, Tip, and Burn (2)
Initiating User Commands
StarkWare built a Reddit Chrome Extension (RCE) that monitors user activity on the Reddit website. The RCE catches events such as Subscribe (clicking the subreddit “JOIN” button), and Tip (adding a response starting with “/tip”), and interprets them appropriately. Whenever the RCE catches a user command, it constructs the required StarkEx transaction, and requests the user to sign it with their selected wallet. The signed transactions are passed by the RCE to the StarkEx Scalability Engine (SESE) in the cloud. StarkEx batches transactions, generates a STARK proof attesting to their integrity, and writes to Ethereum the proof, a commitment to the updated user balances data structure, and the modified user balances.
Frictionless User Experience
Users limiting themselves to the basic Reddit Point interactions (namely: claiming Points, subscribing to a subreddit, tipping other users, and burning Points) need not interact with Ethereum, and in particular, no on-chain registration is required. Only when users choose to interact with Ethereum, e.g. to withdraw or deposit Points, do they need to register on-chain as well. On-chain registration simply means linking a user’s Ethereum address with their StarkEx account.
Wallet Support (3)
Several wallets support the StarkEx ECDSA signature scheme and APIs, offering maximal security to their users. These wallets securely present to the user StarkEx transactions in a clear and readable format, so the user knows what they are signing. This ensures that any attempts at tampering with the message (e.g. by malware) can be detected by the user prior to signing.
Currently provided by: Ledger, Authereum, Portis, and Argent (via WalletConnect).
Where Native Integration with StarkEx has yet to be completed, we opted for Standard Integration. For the Reddit bake-off, these wallets are used strictly for the secure storage of the user’s private key. When using such a wallet, the RCE itself signs the message with the key it obtains from the wallet.
Currently provided by: MetaMask and Torus.
StarkEx Scalability Engine (4)
The SESE runs in the cloud, and is responsible for batching transactions, generating a STARK proof attesting to their integrity, and updating a commitment (a hash) to the new state of accounts following this batch. StarkEx sends to Ethereum the STARK proof, alongside the commitment. The StarkEx smart contract system checks the proof, and if it is accepted, it stores the commitment on-chain. StarkEx accompanies each proof sent to Ethereum with the list of modified account balances verified by the proof as well (aka on-chain data availability), thus ensuring the anti-censorship mechanism described below.
StarkEx Batch Explorer (5)
The StarkEx batch explorer connects to the SESE. It allows viewing the batches created, and the transactions in each batch. The batch explorer also displays a readable format of the modified accounts data that StarkEx puts on-chain, which the explorer reads directly from the blockchain. Note that the set of transactions displayed requires trust in the explorer, as it cannot be derived merely from observing the commitment and the modified accounts recorded on the blockchain.
Serving All or No One
In StarkEx, a user should always be able to withdraw their Points to the Ethereum blockchain, as ERC-20 coins. In the standard flow, a user sends a withdrawal request to the SESE via an off-chain API. Off-chain API service requires trust in the Operator (e.g. system availability). If a withdrawal request isn’t serviced by the Operator, the user submits a Full Withdrawal request (think of it as the equivalent of filing a complaint to a trustless party) to the StarkEx-Reddit Smart Contract. This triggers a grace period during which the Operator may submit a proof serving the withdrawal request. If that happens, the system reverts to its normal operation. Otherwise, the smart contract freezes the StarkEx system by declining to process any further updates.
Withdrawing Points from a Frozen StarkEx
When the system is frozen, users can claim their Points and withdraw them on-chain , by demonstrating to the smart-contract that they indeed own the claimed assets. The commitment stored on-chain is actually a Merkle tree commitment to the user balances. A user can withdraw funds directly from the contract by providing a Merkle authentication-path from their account (a leaf in the tree) to the root (the commitment kept on-chain). The on-chain data-availability sent with every batch processed contains the information needed to allow a user to construct such authentication paths (the data is broadcast solely for this purpose).
¹ Briefly, SNARKs require computationally heavy number-theoretic cryptography while STARKs use lean (post-quantum safe) symmetric cryptography. See this post for a more detailed survey and comparison of deployed proof systems.

We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution!
Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality.
Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining.
This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD.
SolutionsSyscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure.
Syscoin + Matic IntegrationMatic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both.
Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole.
Proving Performance & Cost SavingsOur POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal.
On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process.
Addresses used: 100,014
The demonstration was executed using this tool. The results can be seen in the following blocks:
It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources.
Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network.
Cost SavingsTotal cost for these 100k transactions: $0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11
Snapshot of live fee comparison chart
Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions.
Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value.

Superblock Validation Battles
HOWTO: Provision the Bridge for your ERC-20
HOWTO: Setup an Agent
Developer & User Diligence
Trade-offThe Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms.
The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here.
CostEthereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens
Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction.
Z-DAGZero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends).
APISyscoin-js provides tooling for all Syscoin Core RPCs including interactivity with Z-DAG.
DocumentationZ-DAG White Paper
Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana
Trade-offZ-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds.
Syscoin SpecsSyscoin 3.0 White Paper

Waiting for ETH fees to become cheaper
From now on, every Monday we will be doing a weekly news digest where we will be discussing the biggest stories on the crypto market over the previous 7 days. Why are we doing that? It’s simple — we want to create a useful news outlet for our community members’ convenience.
So, what events marked the third week of September?
Analysts predicting a Bitcoin price rally
“The whale exchange ratio is at the lowest level of the year — the fewer whales moving to the exchanges, the fewer spills and [a] higher BTC price”, said CryptoQuant CEO Ki Young Ju on Thursday. This indicates a possible price rally soon: the less coins whales send to exchanges, the less chance there is for the price to dump, therefore, the higher the chance for a price rally. This is proven by experience: the last time this figure dropped from the current level in April 2019, Bitcoin price grew from $4000 to $13000 over a few months.
FORSAGE.io — how is this information useful to us? It’s important to remember that whenever the first cryptocoin’s price goes up, altcoins invariably follow suit. This means that if BTC shoots up in value, the possibility of TRX and ETH going up also increases, and that’s great news for the entire FORSAGE community.
Is Ethereum still going the Proof-of-Stake route?
A leading Ethereum developer, Danny Ryan published the official Ethereum Improvement Proposal EIP-2982 that implies the launch of Ethereum 2.0 and the switch to Proof-of-Stake. If his proposal gets passed, it may become implemented into the network, solving the issue of high commission fees.
FORSAGE.io — how is this information useful to us? The high commission fees on the ETH network has been slowing down the growth of the FORSAGE community for the past month, because the price of tens and even hundreds of dollars per transaction is unacceptable to most people. We are all looking forward to the day this issue is solved.
DeFi projects boom
DeFi projects are becoming more and more popular — for example, Uniswap, a decentralized exchange, saw its token rise in value by 75% after listing on world’s leading exchanges, making it on the list of top 50 highest market capitalization assets.
FORSAGE.io — how is this information useful to us? It is DeFi projects and their popularity that catalyzed the unprecedented increase in transactions on the Ethereum network, driving the price of transactions further up. After the price of gas for Ethereum transactions has been hovering above 100 Gwei for the past few weeks, on September 17th it jumped all the way to 700 Gwei. This is why we are very excited about the previous news story — the launch of Ethereum 2.0
Over 10% of all crypto payments take place in Eastern Europe
Chainalysis has published another study that shows 12% of all cryptocurrency transactions that took place from July 2019 to June 2020 happened in Eastern Europe! This means the region is the fourth biggest market in terms of transaction volume, and while it is out-grossed by the giants that are the US and China, the region is growing quickly.
FORSAGE.io — how is this information useful to us? The Eastern European region is developing, in part, driven by the increasing commitment of many countries to decentralization and economic freedom. This positively affects the local levels of crypto activity. Let’s find out where the majority of the FORSAGE community comes from! Leave a comment with your country below!
Serum is the world’s first completely decentralized derivatives exchange with trustless cross-chain trading brought to you by Project Serum.The Serum Project is aiming to create both a decentralised exchange and a cross-chain swapping mechanism. In this article, I’m going to focus solely on the cross-chain swapping aspect of Serum.
“[The] Smart Contract is programmed to parse whether a proposed BTC blockchain is valid; it can then check which of Alice and Bob send the longer valid blockchain, and settle in their favor”This is not a trivial problem, and it is unclear how this actually works from the explanation given in the Serum whitepaper. What actually needs to be presented to the smart contract to prove a Bitcoin transaction? Typically when talking about SPV the smart contract would need the block headers of all previous blocks and a merkle inclusion proof. This is far too heavy to submit in a dispute. Instead, Serum could use NIPoPoW, however, these proofs only work on chains with fixed difficulty and are still probably prohibitively too large (~100KB) to be submitted as a proof to a contract. Other solutions like Flyclient are more versatile, but proof sizes are much larger and have failed to see much real-world adoption.
Serum is anticipated to include a limited governance model based on the SRM token. While most of the Serum ecosystem will be immutable, some parameters without large security risks (e.g. future fees) may be modified via a governance vote of SRM tokens.
This figure represents the total worth of transactions in the Ethereum network over the course of five years.submitted by buytexchange to u/buytexchange [link] [comments]
According to CoinMetrics, since the day Ethereum went online in July 2015, the total volume transacted through the network has reached $986 billion.
A few facts:

On the basis of capacity expansion + diversion, ETX can not only play the role of digital payment, but also serve as a media role for on-chain applications, without being bothered by network congestion.According to data from etherscan, the transfer fee of Ethereum recently reached a three-year record high of 709 Gwei, and the sky-high GAS have made Ethereum users miserable. Although the DEFI market has gradually cooled down recently and returned to rationality, the average GAS has declined, but it is still as high as 44 Gwei.
Based on the current Ethereum price of $389.52, if you want to send a transfer to the Ethereum network relatively quickly, you will need a transfer fee of about $1.39. Regardless of the amount of money you send, this $1.39 GAS is essential, because the decentralized network is packaged and traded by miners, and the miners choose to give priority to the transactions with more handling fees. They will not include the proportional GAS according to the amount you send.
What is the reason for the high GAS?
To understand this, we need to first understand what GAS is:
Every transaction on Ethereum needs to be packaged and confirmed by miners, transaction data also needs to be stored on the Ethereum blockchain, and each block volume has a strict limit. Most miners will choose profit first. When processing transactions, they will rank gas prices from highest to bottom, and give priority to processing those with higher gas prices. If you are in a hurry to trade, you need to increase the gas price so that the miners can see you earlier; If you are not in a hurry, you only need to set a gas price, which is above the bottom line of the gas price set by the miners.
The price of Gas is determined by the miners. If the fuel price is lower than the minimum requirement of the miners, the miners will refuse to process the transaction.
Ethereum's method of obtaining GAS has aggravated network congestion and increased handling fees to a certain extent.
1.DEFI’s recent popularity has largely caused the frequent sending of transactions in Ethereum., which has exacerbated the increase in Gas. Since Compound started ‘liquid mining', many other DEFI projects have been imitating, attracting a large number of econnoisseur to enter arbitrage mining. Frequent transactions, redemptions and other operations have caused the Ethereum network to block.
ETX (Ethereumx·NET) has a unique way to solve problems
ETX has made a lot of changes on the underlying basis of ETH, and provides its own solution to the problem of network congestion caused by high gas costs.
The first is to increase the block size to 8MB: theoretically a 1MB block can pack about 2000 transactions, then 8MB size can pack about 16000 transactions. According to the ETX Foundation, as the number of transactions grows, it is not ruled out that larger blocks will be adopted through community voting in the future.
The second is shunt diversion: ETX combines the two proof mechanisms of POW+DPoS. After DPOS goes online, DPOS nodes will be used to classify transactions. Ordinary transactions use 99 DPOS nodes to process transactions within seconds; and transactions that require contract interaction are packaged and traded by miners.

The Gemini crypto exchange is open in essentially all US states, similarly as UK, Canada, Puerto Rico, Singapore, South Korea, and Hong Kong. In 2016, Gemini transformed into the world's recently approved Ether exchange.
It positions 82th greatest exchange on earth as showed by 24-hour volume on Coinmarketcap. While Gemini Bitcoin and Gemini Ethereum trading volumes are high, the exchange is endeavoring with all undertakings to fight with those stages offering a predominant piece of the cryptographic types of cash, for instance, Binance.
Gemini offers crypto to fiat portions and a BTC/ETH grandstand, which makes it a quick contender to any similarity to Coinbase, Bitstamp, and Kraken. At present, it is one of the most respected and ensure about exchanges open. This is in light of the fact that it has more features to help secure customers against developers.

Our Token Presale officially launched on January 6th, but it has been open to the public since January 1st, and we are pleased to report that Phase One is already sold out. We are now just over midway through Phase Two (see chart A below).submitted by 1X2T to u/1X2T [link] [comments]
Note that while the Presale is open to the public, the ICO & IEO phases will be void where prohibited (USA, China, S Korea, etc). In addition, the Presale offers a substantial discount to the future set price of ICO/IEO offerings.
Over the December holidays, we were very active:
· Created customized coding for Token
· Launched the 1X2T (Token) blockchain, as an ERC-20 Ethereum platform token
· Created Telegram channels for Newsfeed and General Community
· Created a marketing team
· Active coordination with hosting partners and advertisers, in preparation of ICO
(see links at bottom, for more info)
For the tech geeks out there, here is a quick rundown on the ERC-20 alterations, and the pseudo PoS nature of the 1X2T token.
The Token acts much like a PoS (proof of stake) product, with a layered ROI%, depending on amount held in whitelisted wallets (see chart B below).
Our 1X2Dev has customized the general ERC-20 contract, to allow us specialized operations that are not normally available. He created 10 bots and 4 node helpers to handle customized functions:
· Single send, mass batch transactions. These allow payment of daily staking rewards to multiple addresses with a single gas (gwei) fee
· Variable ROI%, automated staking rewards, based on amount of Token held
· Automated separation of whitelisted Token addresses (eligible for staking rewards) and regular Token addresses (ineligible for staking rewards)
This last feature allows us to create added incentive for holding the Token, while removing unwanted inflation from Tokens held on exchanges and non-whitelisted wallets (see chart B below).
For those seeking more information on this and more detail on whitelisting, consult our Medium article, that explains all in more detail:
For 1X2 Coin holders
Due to the overwhelming success of the added MNs, and in consideration that many people were not able to capitalize on the free tokens due to the holidays (out of town, buying gifts, etc), we have extended our 3:1 token rewards for all new Masternodes created in the month of January. Simply fill out the 2nd form that 1X2Mod has provided. In addition, for any high rollers that are adding 10 or more MNs, DM 1X2Dev personally, and he will put a VIP rush on those.
