I need to see real growth in metrics like customer acquisition and trading volume before making a deeper commitment. From what I can tell, the news about EDXM will only be positive for Coinbase if it helps to expand the pie for the crypto industry as a whole. That's right -- they think these 10 stocks are even better buys. Independent nature of EDXM would also restrain the firm from the possibility of conflicts of interest. EDXM needed to prove its utility to stay relevant within the crypto space though. For now, I'm taking a wait-and-see backed crypto exchange with Coinbase. Meanwhile, the EDX exchange would work to accommodate both private and institutional investors.

Dex arbitrage An arbitrage transaction is the act of buying a token on one exchange i. Uniswap and then selling the same token for a higher price on another exchange i. Users can do this transaction in one go thanks to the mechanics of the blockchain. Sandwich trading A sandwich trade runs on the back of DEX arbitrage opportunities. So where do Flashbots come in? Some searchers started to use generalised frontrunners.
They would: Watch the mempool where transactions sit for profitable transactions Copy presumably profitable transactions and replace the addresses with their own Once frontrunners confirmed a transaction is indeed profitable, they would raise the gas price on their transaction to frontrun the original transaction and take the MEV that the original searcher found.
In response, new services emerged. Flashbots is an independent project which extends the go-ethereum client with a service that allows searchers to submit MEV transactions to miners without revealing transactions to the public mempool.
This solved the issues caused by frontrunners and has helped bring down high gas prices. MEV-Boost is open source middleware that validators can run to access a competitive block-building market. The middleware allows validators to access blocks from a marketplace of builders, MEV-boost will simply plug into your consensus client, allowing you to outsource specialised block building without having to know the technicalities of how it all works.
These builders produce blocks that contain transaction order flow and a fee for the block proposing validator. The Flashbots team found that separating the role of proposers from block builders promotes greater competition, decentralisation and censorship-resistance for Ethereum.
Distributed Validator Technology Distributed Validator Technology DVT refers to an Ethereum validator running on multiple non-trusting nodes to improve fault tolerance and security. It removes the single-point of failure problem. DVT creates decentralised staking infrastructure that makes it possible to distribute the operations of an Ethereum validator, improve security, increase inclusivity and network decentralisation.
What is a validator client? A validator client is the software that acts on behalf of the validator by holding and using its private key to make attestations about the state of the chain. A single validator client can hold many key pairs, controlling many validators. The risks involved with traditional validator client setups Validators sign messages using their staking private key.
The key is only accessible by the validator client software, which is in place to schedule the creation and signing of messages based on the duties that are assigned to the validator. If you do not operate your own validator, you need to hand over the staking private key to the operator you are using, this creates an assumption where you need to trust that the operator safely and securely stores the staking private key.
If the validator client software does not create timely messages to perform validator duties, the validator will suffer an activity leak which will reduce their ETH balance This can be caused from software bugs, internet downtimes, hardware issues and power outages etc.
A few solutions have been developed to help solve these problems, SSV network is a research and development project that received a grant from the Ethereum Foundation in to work on ways to solve traditional validator client setup shortcomings.
How does SSV do this? At present, validators must be run on one single node, which presents a single point of failure. If that node needs maintenance or goes offline because of a problem, it may get slashed. SSV splits the validator key of that node into multiple KeyShares and distributes them to various nodes, if a node goes offline for one of the reasons mentioned above, the rest of the nodes holding the KeyShares will respond and operate the validator to ensure no downtime.
This creates a secure staking solution where users do not need to hand over validator keys to operators, solving the current issue with staking private key handling. Simplify the process of setting up a validator for people with little to no technical knowledge or prior crypto exposure. Build a base for the Ethereum staking community to build upon.
To ensure that the decentralised ethos continues to remain at the core of the network SSV. Network aims to be a fundamental component in the Ethereum ecosystem. Therefore, EIP was put forward as a quick fix, to potentially reduce these fees by almost another order of magnitude, at least in the short term.
The problem here is that if the gas cost of calldata is lowered, Ethereum blocks could become larger which could cause too much centralisation pressure. The current gas limit is 30 million units, with a target of 15 million. This was considered too large and therefore the proposal also includes a new limit, a calldata blocksize limit of 1MB. Some have argued increasing this limit to 1. We even wrote a book about it! Although of course, the target block time in Ethereum is far lower than 10 minutes, around 13 seconds now and 12 seconds after the transition to Ethereum 2.
Rollups It is at this point that it is probably worth trying to explain what a rollup is. Using a rollup, transactions are processed and executed off-chain, but the transaction data is still included in the main Ethereum chain, such that there is no significant blockspace saving as a result of the rollup.
Therefore, rollups are a sidechain system, the latest and perhaps most advanced iteration of the idea originally proposed by Bitcoin developer Johnson Lau all the way back in The rollup sidechain is EVM compatible and one can use Solidity smart contracts.
Therefore a blockchain is required to get the full functionality of Ethereum. The benefits here are scalability. The sidechain does not have the restrictive computational gas limits of the main chain, therefore throughput is higher and transactions should be cheaper. The downside of rollups are that the sidechain requires new consensus agents and these agents have the power to order transactions.
There is also the problem of moving funds from the sidechain to the mainchain, which is necessarily slow for security reasons. The way these work is that users assume the rollup state is valid, however sidechain validators have the ability to submit a fraud proof to the main Ethereum chain if the rollup is considered invalid. This proof can then be verified by all mainchain Ethereum nodes. The entity which puts the original rollup transaction data into the Ethereum chain is also required to put in place an Ethereum bond.
In the event they submit an invalid state and this is proven, they can lose their bond. This incentive structure is designed to keep the rollup sidechain secure. There are some parallels here with proof of stake systems and penalties for bad behaviour. This bonding type system may seem complex, unnecessary and even a bit weak. For instance how do system designers ensure the bond is of sufficient value to deter fraud, while also that entities have enough liquidity? This could be challenging given the large and volatile flow of funds in the space.
One needs to make several assumptions in order for such a system to be necessary: Throughput on the sidechain is high, such that not many entities run a fully validating sidechain node and the sidechain system is too centralised to be secure Storing data on the mainchain is cheap, while computationally the system is capacity constrained In this scenario this complicated bonding system may make sense and the sidechain, which itself is considered insecure, is secure enough due to the fraud proof and bonding system.
Ethereum may currently be in a sweet spot where optimistic rollups make sense. Therefore there is considerable excitement about optimistic rollups and many consider them critical to scaling Ethereum. Rollups in the Bitcoin context There is another irony here, when rollups are evaluated in the Bitcoin context.
They have claimed that this process should occur off-chain, while only the data and results of these computations should appear on-chain. This is exactly what rollups do. The answer is yes, Bitcoin can, in theory anyway. Infact, if one was to try to execute these types of smart contracts on Bitcoin then it must do rollups, because there is no way of making existing Bitcoin full nodes validate these complex smart contracts.
Therefore, the only way of doing it would be to put the smart contract data on the Bitcoin blockchain, and have the smart contract transactions executed and validated by other node software, which runs the sidechain. Technically you can argue that in order to be a real rollup, the layer 1 transaction must be able to enforce the layer 2 transactions, since on Bitcoin you cannot do this, perhaps it should not be called a rollup.
However, on Bitcoin, with this type of sidechain construction you can still do almost anything, including making the system Ethereum Virtual Machine EVM capable with Solidity smart contracts. Of course such a system may not be effective or efficient on top of Bitcoin, but in theory it could work.
One weakness of creating this sidechain rollup type system on top of Bitcoin, is that unlike with Ethereum, you could never do the fraud proof, optimistic rollup type system. However, it is not clear to us that this would be needed or desirable.
