THΞGABO🍌 · 1490· 1y ago61“What a great project!”I think Ethos is a great idea. The way I see it, blockchain is forever. So, while the assets a wallet controls may have value, the reputation associated with that address can be quite valuable too. Assets can be sent to another address at any time, but the identity behind that wallet is not so easily transferrable. Ethos is the best implementation of that sentiment imo. Onchain identity is hard to establish and the older a wallet gets, the more valuable that characteristic becomes. This is why I've never used multiple wallets to farm a project for an airdrop. I like to do everything I feel safe doing in my main wallet because I want that history to be onchain...not split across many burner wallets. Much respect for Serpin Taxt for building out this ecosystem! I can truly see it being here for the long term.

Later on he presented the app and held an AMA for a group I'm in, and I quickly understood that his mind was dead set on building, building, building. Since then, I've been seriously impressed by his work ethic and dedication to the platform. Thank you Serpin!

afrex · 1466· 1y ago59“Incredible Builder”Admittedly, Ethos is the first time that I’ve interacted with Serpin but I’m very impressed with what I’ve seen here He’s very open to feedback with the product he’s building and is always looking to iterate forward which is an absolute must in such a quick moving space CT has needed something like Ethos for a long time now and I’m excited for it’s future which is being built out in a robust but flexible way

Knox · 1529· 1y ago59“Insanely Active Founder”For someone that is building one of the most popular platforms in crypto rn, Serpin is excellent at engaging with his community, answering questions and tickets, and giving back to people who legitimately contribute All of the questions I have asked in the discord he has answered himself as founder rather than relying on mods to do everything for him. I definitely respect his work ethic and the fact that he is putting in the work on the community himself

Zaddy · 1852· 1y ago59“Great Founder”I appreciate Serp lots! I only recently met him through the Ethos hype. Funny enough I initially wasn't the biggest fan 😂 He had left a negative review on someone I personally liked, without much grounds it felt like. Shortly after, he had a discussion with that person and ended up coming to a resolution. Post that interaction I kept a bit of an eye on him, and noticed that's just how he is. He's blunt and will say things as he sees them, always being open to discussion and to shift his mind to the positive if you're convincing enough or he realizes he's out of line. His intent is always positive. Really enjoying the product so far and wishing you success bro.

Yugheld · 1361· 1y ago59“A builder worthy of an ideal product and beyond.”He is building a product that has a very high chance of actually implementing an on-chain + social reputation economy system that was once considered ideal. As one of the leaders of this visionary project, he sets a great example. He actively engages with new communities by replying directly on Twitter and strives to properly communicate the product he is building. He is truly an ideal builder.

Rejamong · 1422· 1y ago59“The Best Kind of Builder”Serpin has caught lightning in a bottle having built a product that assesses and scores credibility in a time where credible people are in short supply. You couldn't blame him for seizing the moment to extract maximum financial value from Ethos. Instead, Serpin is growing Ethos with a great deal of thought and care, slowly expanding access and rolling out features. He regularly solicits feedback from his community and Ethos's initial users and, in a fashion atypical for founders, seems to genuinely consider that feedback in his direction of the platform. Needless to say I'm a fan.

HammerToesKnows · 1354· 1y ago59“Not performing leadership, he's walking the credibility walk”we’ve been engaging with Serp for a while now — from the start, it was clear he operates with a rare mix of visibility and responsiveness he runs AMAs, answers tickets himself, pushes updates fast and stays close to the people using the product: he’s not larping leadership, he’s doing the work decision-making is more based on informed by constant dialogue, rather than internal conviction not so often you see a founder that his credibility doesn’t come from positioning but from showing up, fixing things when they break and taking responsibility when something doesn’t land many founders build tools, but very few build trust and he’s doing both, I've seen it up close my impression of him is excellent (even though he plummets my cred score once per week)

I hope it works out and helps to empower people with trust! I also would love to interview you on the onchain heroes podcast because you're building an onchain consumer product and you're sure to be a true hero in this space soon enough!
