Robinhood's choice of technology for its crypto business once again validates the attractiveness of the Ethereum ecosystem. According to Johann Kerbrat, the company's head of crypto, the team ultimately decided to build a Layer-2 network based on Arbitrum rather than launching a separate Layer-1 chain from scratch.

The logic behind this choice is clear: rather than redeveloping consensus mechanisms and security infrastructure, it’s better to directly leverage Ethereum’s security and decentralization properties. At the same time, the EVM compatibility within the Arbitrum ecosystem and existing liquidity enable Robinhood to quickly gain trading depth and developer support. This allows the team to focus on truly differentiated products—such as innovative applications like stock tokenization.

From the Layer-2 track, this pragmatic architectural choice has become the mainstream consensus. Directly relying on Ethereum’s security layer and focusing on business innovation is increasingly becoming the preferred path for many applications.

Talking about Ethereum again, it's just that there are no good independent chain solutions. Is the liquidity in the Arbitrum ecosystem worth bragging about? It's just because they rely on Ethereum's support. The choices of these big companies are all the same, just to make things easier. True innovation should be creating their own chain. Right now, everyone is hiding behind L2. Let's see if stock tokenization can finally be implemented; otherwise, it's just another bearish project.

Honestly, Robinhood's move this time shows smart people. Why reinvent the wheel? --- Arbitrum has won again, everyone is piling into this. --- I just want to know when the tokenization of stocks will truly land, not just another PPT revolution. --- Ethereum ecosystem is indeed highly sticky, but it seems that stacking Layer2 solutions could also lead to problems. --- Using security as a logic is indeed appealing, saving time, effort, and money. --- But if this continues, will Arbitrum become the next centralized hub? --- Differentiated products are the key; technology choices are actually secondary.

There's really no need to bother restarting a chain; if there's already a proven security system, why be a fool? --- Arbitrum is stable this time, big companies are using it. --- Honestly, Ethereum still wins big; no one can escape this ecosystem. --- Tokenizing stocks sounds pretty exciting, but can it really be implemented? --- This is called pragmatism, much better than those who want to create new public chains every day. --- So now everyone understands that building security infrastructure yourself is a suicidal innovation. --- However, with so many applications in the Arbitrum ecosystem, how can Robinhood still find a position? --- It seems that the key to winning with layer2 really is a combination of security and liquidity.

Ha, this is the choice of smart people. Instead of messing around with your own chain, it's better to just lie back and make money on Ethereum's security. --- Arbitrum has won again this round. Honestly, I envy the decision-making efficiency of these big companies. --- Instead of spending effort building a chain, it's better to focus on product differentiation. This logic makes sense. --- Tokenizing stocks sounds good, but I’m not sure how the compliance part will go. --- The direction for Layer2 integration is already very clear. Building a new wheel alone is indeed exhausting and unprofitable. --- True pragmatism—no fancy ideas, just steady money-making. --- It feels like the Ethereum ecosystem is like a black hole; all big companies are jumping in. --- Using the security layer to save costs is a classic move. Other chains look pretty awkward by comparison.

Damn, Robinhood's choice this time is really pragmatic—no hype, no negativity. --- Another big player has thrown in the towel; the L1 dream is shattered. --- Basically, they're riding on Ethereum's boat to seize the beachhead—this tactic has been played out now. --- Arbitrum's liquidity is indeed pretty good, but can it really make Robinhood take off? --- Haha, so L2 is the future, the old L1 ledger really has become obsolete. --- Tokenizing stocks is a big gimmick; will actual users buy into it? That's the real question. --- EVM compatibility is always useful; anyway, everyone is doing it this way. --- Gotta say, this choice saved them a lot of trouble. --- Now Arbitrum is about to get hyped up again; this is how ecosystems get pumped. --- Wait, what about Robinhood's security? Could Arbitrum be a new trap?
