6 Reasons Why Serum Won't Succeed

6 Reasons Why Serum Won't Succeed

The world of DeFi is exploding but is it all it’s made out to be?

DeFi (decentralised finance) is most certainly the buzz in the crypto world this minute. It’s bringing similar feelings which was the 2017/18 ICO phase, where a mammoth of new projects begun to explode onto the scene, each with their own promise of new innovation and use case.
Hindsight has shown us that most of those projects have ultimately failed, or worse, were outright scams that took advantage of not so wise investors looking to make a buck. Obviously, not all projects fit that description, with many teams still around today working on and delivering their individual visions. Crypto is, after all, still a big experiment of new technology.

Enter DeFi: Serum

DeFi has exploded into the limelight over the last few months, with some tokens appreciating hundreds of percent in price. It appears to be the catalyst that has driven a huge market shift in the crypto world, and for those who’ve been around a number of years, this is a welcome change.
In this piece, I’m going to examine a particular project called Serum.
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.
Although the Serum whitepaper is quite short and lacking in detail, it is useful to derive some understanding of how the cross-chain swapping protocol should work. Throughout this review, I will use it to describe how the imagined protocol works.

Overview

Let's assume Alice wants to trade some BTC for ETH and Bob wants to trade some ETH for BTC using Serum. These two users are matched and agree on a price using an on-chain order book on the Solana blockchain (whitepaper provides no practical details on how to do this).
Once these users are matched, Bob must send the ETH he wants to trade to an Ethereum smart contract, plus some amount of ETH ~200 USD worth (see section 4 below) to the smart contract as collateral. Alice will also need to send some collateral to the smart contract. Once this initial setup process is complete Alice then has to send her BTC to Bob’s BTC address and if Bob receives the BTC from Alice he can then release his ETH from the smart contract sending it to Alice’s ETH address. Upon completion of this both Alice and Bob are refunded their ETH collateral.
So what happens if something goes wrong? For example, say Alice never sends BTC to Bob, after some period of time Bob can initiate a dispute. When the dispute begins both Alice and Bob present a portion of the Bitcoin blockchain information to the smart contract (see section 3). The smart contract then decides whether or not Alice did send BTC to Bob. If she hasn’t then the smart contract returns Bob's ETH and collateral to Bob and also takes Alice’s ETH collateral and gives that to Bob. The same occurs in reverse if Alice sends BTC but Bob never approves the transfer of ETH from the smart contract.
This scheme seems pretty simple, there’s no oracles and no centralised parties, however, it has a number of disadvantages.

1. User-Provided Collateral Is Bad for User Experience

Each time a user conducts a swap they must reserve some percentage or fixed amount to cover the collateral for the swap. This collateral amount needs to be present to prevent griefing attacks where users initiate swaps with no intention of ever following through and sending funds to the alternate participant.
However, this creates a poor user experience as both Alice and Bob need to have at least the value of the dispute fee committed to the contract in collateral before they conduct a swap. This is totally foreign from the normal exchange experience in which you only require a single coin and a single transaction to begin trading. For example, if using Serum to trade Bitcoin you would need to hold Bitcoin and ~200$ of Ethereum and also interact with the Ethereum chain before any swap occurs. This adds unnecessary complexity and confusion, especially for newcomers to the crypto space.

2. ETH Must Always Be on One Side of the Swap

Although the Serum method of cross-chain swapping could occur on any blockchain with smart contracts, the Serum whitepaper makes it clear the Serum arbitration contract is going to be deployed on the Ethereum blockchain. This means one party must always be locking the full value of the trade in ETH using an Ethereum smart contract.
This makes it impossible, for example, to do a single step trade between Bitcoin and Monero since the swap would need to be from Bitcoin to ETH first and then from ETH to Monero. This is comparable to other proposed cross-chain swap systems like Thorchain and Blockswap, however since those networks use AMM’s (automated market makers)and decentralized vaults to take custody of funds, the user needs not to interact with the intermediary chain at all.
Instead in Serum, the user wanting to swap Bitcoin to Monero will need to do the following steps:
  1. Send Ethereum collateral to the Serum arbitration contract
  2. Send Bitcoin to the user they are swapping with.
  3. Receive Ethereum
  4. Send Ethereum back to Serum arbitration contract
  5. Receive Monero
  6. Send Ethereum out of Serum arbitration contract
  7. Receive back Ethereum collateral
It might be possible to remove or simplify step 4, depending on how the smart contract is built, however, this means a swap from BTC to Monero would require 2 Ethereum and 1 Bitcoin transaction in the best-case scenario. Compared with the experience of other cross-chain swapping mechanisms, which only require the user to send a single transaction to swap between two assets, this is very poor user experience.

3. Proving Transactions on Arbitrary Chains to a Smart Contract Is Not Trivial

Perhaps the most central part of the Serum cross-chain swapping mechanism is left completely unexplored in the Serum whitepaper with only a brief explanation given.
“[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.
Without explaining how they actually plan to do this validation of Bitcoin transactions, users are left in the dark about how secure their solution actually is.

4. High Dispute Fees Force Large Collateral on Small Trades

Although disputes should almost never happen because of the incentives and punishments designed into the Serum protocol, the way they are designed has negative impacts on the use of the network.
Although the Serum whitepaper does not say how the dispute mechanism works, they do say that it will cost about ~100 USD in GAS to dispute a swap.
Note: keep in mind that the Serum paper was published in July 2020 when the gas price was about 50 Gwei, as Ethereum use has picked up over the past month we have seen average GAS prices as high as 250 Gwei, with the average price right now about 120 Gwei.
This means that at the height of GAS prices it could have cost a user ~500 USD to dispute a swap.
This means for the network to ensure losing cross-chain swaps aren’t made each user must deploy at least $200 in collateral on each side. It may be possible to lower this to collateral if we assume the attacker is not financially motivated, however, there is a lower bound in which ransom attacks become possible on low-value trades.
Further and perhaps more damagingly, this means in a trade of any size the user needs to have at least 300 USD in ETH laying around. 100 USD in ETH for the required collateral and 200 USD if they need to challenge the transaction.
This further adds to the poor user experience when using Serum for cross-chain swapping.

5. Swaps Are Not Set and Forget

Instead of being able to send a transaction and receive funds on the blockchain you are swapping to, the process is highly interactive. In the case where I am swapping ETH for Bitcoin, the following occurs:
If the Bitcoin transaction is never received then I need to wait for a timeout to occur before I can participate in the dispute process.
And on the Bitcoin side (assuming the seller is ready), the following must take place:
If the Seller never accepts the Bitcoin I sent to him then I need to wait on line for the dispute process.
This presents a strange user experience where the seller or seller’s wallet must be left online during this whole process and be ready to sign a new transaction if they need to dispute transactions or unlock funds from a smart contract.
This is different from the typical exchange or swapping scenario in which, once your funds are sent you can be assured you will receive the amount you expected in your swap back to you, without any of your wallets needing to remain online.

6. The Serum Token Seems to Lack a Use Case

The cross-chain swapping protocol Serum describes in its whitepaper could easily be forked and launched on the Ethereum blockchain without having any need for the Serum token. It seems that the Serum token will be used in some capacity when placing orders on the Solana based blockchain, however, the order book could just as easily be placed off with traditional rate-limiting schemes.
There is some brief mention of future governance abilities for token holders, however, as a common theme in their whitepaper, details are scarce:
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.

Conclusion

Until satisfactory answers are given to these questions I would be looking at other projects who are attempting to build platforms for cross-chain swaps. As previously mentioned, Thorchain & Blockswap show some promise in design, whilst there are some others competing in this space too, such as Incognito and RenVM. However, this area is still extremely immature so plenty of testing and time is required before we can call any of these projects a success.
If you’ve got any feedback or thoughts about Serum, cross-chain swapping or DeFi in general, please don’t be shy in leaving a comment.

Relictum Pro transaction speed superiority

Relictum Pro transaction speed superiority
Bitcoin has many problems, but in this post we will focus on the main thing: transactions with this digital currency are carried out incredibly long.
One of the main problems of modern blockchains is large block size. It is 8000 times bigger than our block size (1,024,000 bytes = 1Mb against 120 bytes). It is not advisable to accommodate all transactions that cannot be placed in a single block in a single block. This leads to a decrease in the speed of data processing, a decrease in the speed of data transfer, as well as a decrease in the speed of searching for the necessary information.
The more network congestion, the longer transactions take. And in itself this problem will not be solved. When a new transaction is launched in the Bitcoin blockchain, information about it is visible immediately, but the actual currency transfer may take several minutes or even hours. This expectation is inconvenient to neither buyers nor sellers.
Bitcoin is extremely inefficient in matters of network scaling. Transactions in it as the number of users grows, they become more and more slow and expensive
Relictum Pro speed of transaction
The existing network organization of modern blockchains is peer-to-peer (P2P) network. Relictum blockchain platform uses a unique protocol based on the TCP/IP protocol, in which a virtual communication channel with each node is formed over the Internet. The advantages of this network are its reliable stability and isolation from the general segment of the Internet. In this virtual channel, only Relictum Pro information is transmitted, which increases the data transfer speed several times.
Principle of operation: One node connects to several and in parts downloads data from other nodes. Thus, the download speed was close to the maximum value of the network card and the speed of a provider.
As a transport, we use a new type of network based on the fourth-level data network of the OSI model. _HyperNet is a virtual channel switching network.
The network provides a constant stable connection between all nodes for a small limited period of time (from 0.5 to 10 s), depending on the network load. With a small network load, this gap can be up to 10 s, while with a loaded network it decreases to less than 0.5 s.

Seems like Overstock is not releasing on the Bitcoin blockchain!

They're merely timestamping on the Bitcoin blockchain. http://www.sec.gov/Archives/edgadata/1130713/000104746915008523/a2226515zs-3a.htm#dk40601_about_digital_securities
"In connection with a digital securities transaction, the tØ software will publish the transaction to the proprietary ledger maintained by the Pro Securities ATS with respect to the relevant series of digital securities. Concurrently, the tØ software will electronically publish the proprietary ledger and commence the process of embedding in the Bitcoin blockchain information necessary to mathematically prove the validity of available copies of the proprietary ledger. Specifically, after a set of transactions in our digital securities have been executed and recorded to the proprietary ledger, the Pro Securities ATS will send a de minimis amount of Bitcoin from an ATS-controlled Bitcoin wallet to another ATS-controlled Bitcoin wallet using the blockchain protocol. This blockchain protocol provides for an editable field that can be used to implant code or other data within the Bitcoin transaction that will be embedded into the blockchain, and the tØ software will use this field to implant anonymized cryptographic hash functions for the digital securities transactions reflected on the proprietary ledger into the Bitcoin transfer made by the ATS. The blockchain will validate this de minimis Bitcoin transaction and embed it, together with the implanted anonymized cryptographic hash function, into the Bitcoin blockchain. As a result, once the Bitcoin transaction is immutably embedded into the Bitcoin blockchain, an immutable record of the digital securities transactions reflected on the proprietary ledger is also recorded within the Bitcoin blockchain. The Bitcoin blockchain participants involved in validating the de minimis Bitcoin transaction do not have any access to the underlying digital securities transaction data. The transaction costs associated with this process relate to the de minimis costs of the Bitcoin currency transaction conducted by the Pro Securities ATS. As a result, the Pro Securities ATS—rather than us or holders of our digital securities—will bear such minimal costs required in connection with embedding cryptographic hash functions into the Bitcoin blockchain."

What information solved in blockchains makes bitcoin valuable?

I've read only a bit on it but can't seem to find anything that really explain where the value is derived from.
I get that blocks or tons of information get processed and shoved together, given a hash for identity, and that people spend their times solving or onpacking this information, and can be rewarded with bitcoins for it
What is it about the information in these blocks that warrants bitcoin being worth value?
