In Transient

In Could, blockchain groups have been specializing in testing testnets, opening ecosystems, and securing funding with out a lot hype. These distinguished gamers, with minimal hype, demonstrated vital progress of their discipline.

May 2025 in Crypto: Projects That Mattered Across Blockchains

In case you’ve been scanning the blockchain panorama this Could, you should have seen loads of advertising noise. AI buzzwords stapled onto half-baked roadmaps, the standard rollup clone pile-on, you recognize the drill. However behind that noise, some groups are simply getting on with it: delivery testnets, opening up ecosystems, and touchdown severe funding with out fanfare. We’ve been preserving tabs on what’s been transferring the sector.

The tasks under aren’t essentially new, however all of them made a mark this Could. Some launched a recent replace, others hit actual traction or quietly pulled off one thing arduous. We picked among the most distinguished gamers with the least hype issue as their core mover. Whether or not or to not comply with these is, after all, as much as you – contemplate it merely our tackle the place actual work is (or not less than appears to be) getting achieved. Let’s dig in. 

Web3’s relationship with off-chain information has at all times been a bit fragile. Both you belief some centralized API, otherwise you construct your personal clunky workaround. House and Time is making an attempt to repair that – by decentralizing databases and making each question provable utilizing zero-knowledge cryptography. Mainly: run a SQL question, get a outcome plus a ZK-proof that claims “this information wasn’t tampered with.”

Space and Time launched its mainnet to let developers query off-chain data with cryptographic proof.

Supply: House and Time

That’s the pitch, and in Could, it lastly grew to become actuality. The undertaking launched its public mainnet on Could 8, full with its native token $SXT and a validator community able to go. This wasn’t some stealth deploy both – Microsoft, Chainlink, Google Cloud, and Polygon are already plugged in at numerous ranges, and the workforce claims over 30 validators have been operating throughout testnet. The tech’s legit, and the accomplice listing screams “severe enterprise play.”

Enterprise backers like Google Cloud and Chainlink joined Space and Time to support decentralized data infrastructure.

Supply: House and Time

What caught our consideration is how unambiguous the undertaking is about what it’s for. This isn’t a “come construct something on our L1” form of chain. It’s for devs and information folks – tasks that have to confirm exterior information, run massive off-chain computations, or feed sensible contracts with outcomes they’ll belief. 

Space and Time uses zero-knowledge proofs to verify SQL queries on-chain without revealing raw data.

Supply: House and Time

Token-wise, $SXT is your ticket for querying, staking, and governing the community. They haven’t posted an excellent granular breakdown but, however primarily based on launch comms, it’s utility-heavy – pay for requests, earn as a validator, vote on upgrades, all that.

In fact, we’re nonetheless early right here. We don’t know the way the economics shake out at scale – how a lot queries will value, whether or not devs will discover the UX livable, and even how typically apps really want this sort of bulletproof information verification. However in its nook of the Web3 world, this feels substantial. 

So, our learn on House and Time: not flashy, not mass-market – however for the data-heavy corners of crypto which are uninterested in trusting their guts or Google; might be a quiet spine within the making.

Promoting and blockchain – yeah, we all know. Appears like a type of pairings that ought to keep within the “dangerous concepts” folder with 2018 whitepapers and tokenized soda machines. However now and again somebody swings at it once more, and this time, Progress Protocol would possibly really be connecting with the ball.

Growth Protocol launched ad campaign smart contracts directly into mobile games from day one.

Supply: Progress Protocol

Their pitch is simple sufficient: sensible contracts operating campaigns and settling funds immediately between advertisers, publishers, and (in principle) customers. No middlemen and no sketchy advert networks concerned. Feels like vaporware from a half-forgotten ICO, proper? However right here’s the place it will get attention-grabbing – they really launched. Mainnet hit on Could 21, they usually weren’t simply standing there with a “coming quickly” banner. Two cell video games from Nazara – one of many massive canine in Indian gaming – have been already dwell with campaigns on day one.

Nazara’s games integrated Growth Protocol to settle advertising impressions on-chain in real time.

Supply: Progress Protocol

The declare: 150,000+ each day energetic customers on launch. That’s a head-turning quantity for a model new chain; although we’d be mendacity if we mentioned we weren’t questioning what number of of these have been actual folks, what number of have been bots, and what number of simply confirmed up for the token crumbs. The workforce hasn’t proven its hand on tokenomics but, however primarily based on what’s seen, there’s clearly some incentivization occurring underneath the hood.

Growth Protocol claimed over 150,000 daily users by embedding crypto ad rails inside live apps.

Supply: Progress Protocol

Beneath all of it, the chain runs on Avalanche tech – or extra particularly, a {custom} subnet of it. That offers it the uncooked throughput you’d need for an advert community that’s really doing stuff at scale: assume real-time settlement of impressions, clicks, conversions, and all the info exhaust that comes with it. Emin Gün Sirer himself gave it a nod, calling it a “actual instance of blockchain utility,” which, coming from him, is both an endorsement or a problem.

The platform built its custom adtech chain as an Avalanche subnet to enable high-speed crypto ad settlement.

Supply: Progress Protocol

What we expect is going on (since full docs are nonetheless MIA) is a local token driving transactions and rewards, probably with choices for advertisers to burn or stake for visibility boosts. Campaigns should be priced off-chain in fiat, however on-chain settlement seems totally crypto-native. The entire thing gestures at a bigger imaginative and prescient – possibly one thing like NFT-based advert items or “tokenized objectives” down the road. And the entire practice appears to be headed in direction of programmable advert stock.

In fact, none of this solutions the massive questions. First: is the exercise sticky, or simply inflated by launch rewards? We’ve seen many “energetic networks” vanish the second incentives dry up. And second – the tougher one – will precise advertisers purchase in? Transparency is nice n all, however to date, blockchain has principally delivered extra friction, not much less, and that’s not what the advert world needs.

Nonetheless, we’ll give credit score the place it’s due: this factor is dwell, already embedded in video games, and pushing previous the everyday Web3 echo chamber. Not precisely polished, and it’s positively not easy – however for all of the hand-wavy “blockchain meets adtech” makes an attempt we’ve watched fizzle out, this one appears to have precise momentum.

Aztec’s at all times been the quiet one within the zero-knowledge crowd. Whereas everybody else was hyping benchmarks and buying and selling blog-post drama, they have been simply quietly constructing. After which Could rolls round, and eventually – public testnet is right here. For anybody who’s been ready on an actual shot at non-public sensible contracts on Ethereum, this was the one to observe.

Aztec rolled out its public testnet to enable encrypted Ethereum smart contracts by default.

Supply: Aztec.community

Now, if Aztec sounds acquainted, that’s as a result of it’s. They’d an earlier run with Aztec Join – a kind of privateness layer for dApps, the place you can do encrypted DeFi transactions. That obtained sunsetted again in 2023 after they determined to start out recent and purpose larger. What they’ve rolled out now could be the fruits of that pivot: a full-blown zkRollup the place the whole lot – sensible contracts, state, interactions – is encrypted by default. Not partially non-public, not “stealth mode” toggles. The whole lot.

Developers began writing private dApps in Noir as Aztec's testnet unlocked full zk privacy tooling.

Supply: Aztec.community

This testnet is the primary time devs can correctly get their arms soiled. You’ll be able to write contracts in Noir (their custom-built language), deploy dApps that truly don’t leak person information, and begin stress-testing what Ethereum seems like when it forgets your online business. It’s not precisely mainnet-ready – efficiency nonetheless has that early-testnet shakiness – however you possibly can really feel the rails being laid down for one thing severe.

Aztec designed its zkRollup to encrypt smart contract data end-to-end on Ethereum.

Supply: Aztec.community

That mentioned, there’s some historical past right here, and never all of it neat. Shuttering Aztec Join spooked quite a lot of devs – it raised that quiet fear: if one privateness system can disappear, what’s stopping one other? After which there’s the apparent warmth that full encryption brings. This isn’t some “we obfuscate metadata” play. It’s straight-up end-to-end encrypted Ethereum. That’s highly effective… and likewise regulatory kryptonite if dealt with unsuitable. Aztec’s going to need to tread rigorously if they need this to be greater than a distinct segment for cypherpunks and privateness diehards.

On the backer facet, although, they appear fairly stacked. a16z, Paradigm – the standard top-tier suspects. No token but – and no hints about when one would possibly arrive – however it’s arduous to think about this going mainnet with out one thing to safe and incentivize the community.

Make no mistake although: Aztec isn’t chasing the identical dragon as most rollups. This isn’t about gasoline wars or memecoin throughput. It’s not making an attempt to out-Bedrock Optimism or undercut charges on Base. It’s primarily constructed for issues like encrypted voting, privacy-preserving DAOs, and institutional logic that completely can not go on a public ledger. 

Ultimate take: it is a massive deal for Ethereum privateness. It’s early, certain, and never with out its baggage. However it’s actual, it’s right here, proper now.

Everybody in crypto likes to say we want “real-world use instances,” however often which means fintech clones or loyalty factors with additional steps. Hardly ever does the dialog veer into… mental property regulation. However that’s precisely the place Story Protocol is staking its floor – and surprisingly, it’s not a half-baked area of interest undertaking. This factor is a whole layer-1 blockchain constructed particularly to register, license, and monetize IP. We’re speaking songs, characters, storylines, logos – became programmable, remixable, royalty-splitting belongings, all dwelling on-chain.

Story Protocol positioned its L1 chain as a registry and monetization layer for on-chain IP assets.

Supply: Story Protocol

Now, you’d be forgiven for assuming it is a novelty play. However clearly somebody’s shopping for the imaginative and prescient: Story’s raised a cool $140 million from a16z, Hashed, and – in probably the most 2025 crossover conceivable – Paris Hilton’s 11:11 Media. And Could introduced a brand new push: they launched a worldwide “IP Buildathon” with tracks spanning from licensing infrastructure to AI-native copyright instruments, and opened the gates for devs to truly begin constructing on prime of the chain.

The team launched an IP Buildathon to bring remixable copyrights and licenses into smart contracts.

Supply: Story Protocol

Underneath the hood, this isn’t just a few Ethereum sidecar. Story is its personal sovereign chain, constructed with Cosmos SDK however operating an EVM-compatible atmosphere – so that you get flexibility plus acquainted tooling. The native token, $IP, does triple responsibility: governance, gasoline, and a intelligent little burn mechanic. Each time somebody registers content material, licenses IP, or transacts on-chain, a small chunk of $IP will get burned. It’s a deflationary twist that ties token sink on to protocol utilization. Stakers hold the community safe, and everybody from platform builders to fanfic remixers can, in principle, earn a chunk.

Story Protocol built its sovereign Cosmos chain with EVM support to handle IP licensing and token burns.

Supply: Story Protocol

The chain itself has technically been dwell since earlier this yr, so Could was much less about turning the lights on and extra was about firing up the ecosystem. The vibe now could be “early Cambrian,” with Story seeding the bottom and hoping one thing extraordinary grows. Will or not it’s anime-style DAO IP, AI mannequin licenses, or fair-trade Taylor Swift remixes? Too quickly to say, however the items are being laid.

New projects started deploying on Story Protocol as it seeded tools for programmable royalties and IP splits.

Supply: Story Protocol

That mentioned, let’s not fake there aren’t landmines. The authorized facet of on-chain IP continues to be very a lot uncharted territory. Most creators aren’t sitting round ready for his or her Solidity second. And spinning up an entire new L1 as a substitute of constructing on current rails provides a layer of dedication (and friction) that solely is sensible if the ecosystem really reveals up.

However to their credit score, the Story workforce isn’t pretending the arduous components aren’t arduous. They’ve obtained the runway, the tooling, and a thesis that feels extra well timed than it might need a yr in the past. In a post-AI world the place IP possession is about to get significantly messy, there’s a case to be made for placing the principles of engagement on-chain – earlier than they get eaten alive by artificial media and copyright chaos.

Launching a blockchain continues to be, frankly, a slog. Even now, within the again half of 2025, you’re often taking a look at six months, a deep protocol workforce, and a low six-figure funds simply to get one thing vaguely production-ready. Tanssi thinks that entire course of is damaged – they usually’re going for the throat with their “Blockchain in minutes” pitch. Feels like a meme, we all know, however they appear severe.

Tanssi opened its final testnet to let developers launch appchains with one-click deployment.

Supply: Tanssi Community

What they’re constructing is greater than a dev toolkit – it’s a launch platform for full-blown appchains. Sort of like spinning up your personal blockchain server, however with plug-and-play elements: governance settings, consensus layer, Ethereum-compatible dev instruments, and built-in help for shared safety frameworks like Ethereum restaking or Polkadot’s validator set. Underneath the hood it’s constructed on Substrate, so there’s actual muscle behind it. Decide your stack, hit deploy, go dwell. Not less than, that’s the promise.

The platform bundled governance, security, and dev tools into a Substrate-based blockchain launcher.

Supply: Tanssi Community

In Could, they rolled out their closing public testnet – a dry run for mainnet, which is slated to land someday in June. And this isn’t a ghost city testnet, both. Groups are already utilizing it to deploy chains, coordinate validators, and plug into integrations. The Tanssi crew says there are 150+ tasks within the queue – starting from DeFi experiments to real-world asset platforms to gaming networks. That’s quite a lot of exercise, and whereas a few of it’s positively pre-TGE froth (sure, the token is coming), there’s substance there.

Over 150 projects queued to deploy on Tanssi as testnet activity spiked ahead of mainnet.

Supply: Tanssi Community

They’re not flying blind both. Tanssi raised $9 million from a robust lineup – Arrington Capital, HashKey, and even Gavin Wooden himself, which is sensible given the Substrate roots. So this isn’t some fork-of-a-fork dev workforce duct-taping one thing collectively. They’re plugged in with the infrastructure crowd that’s been constructing severe protocol gear for years.

Nonetheless, we’re not all-in simply but. The largest query looming over Tanssi is existential: do most groups really need their very own chains? Cosmos and Avalanche subnets planted that flag years in the past, however uptake has been area of interest at finest. Tanssi is betting the market shifts if the barrier drops – that with instruments like restaking and modular SDKs, groups will favor sovereignty over shared area. Possibly. However we’re not there but.

For now, it’s all about how mainnet lands. Who launches, what sticks, and whether or not these appchains grow to be ghost cities or dwelling ecosystems. A clear testnet is an effective begin – however the actual story begins when worth flows, and we’re going to observe it intently.

If we have been handing out awards for “most formidable undertaking of the month,” Sahara would win it with zero competitors. They’re not simply making an attempt to slap a token on AI – they’re going after the entire stack. Assume: information licensing, mannequin attribution, royalty payouts – all wired collectively by means of an on-chain backend financial system. The pitch is fairly wild: flip each a part of the AI coaching pipeline right into a traceable asset. In case your information helps practice a mannequin, the system is aware of about it, and also you receives a commission. 

Sahara launched a testnet for tracking and rewarding AI data contributors on-chain.

Supply: Sahara Labs

That’s the imaginative and prescient, and in Could, they inched slightly nearer. Sahara dropped its first public testnet – codenamed SIWA – after operating a personal part that got here with some eyebrow-raising utilization stats: 3.2 million whole accounts, 1.4 million each day actives. Both we simply discovered Web3’s most adopted AI infra in a single day… or somebody’s counting very generously. Nonetheless, alongside the testnet, they rolled out a protracted accomplice listing – 40+ names together with AWS, Google Cloud, and UC Berkeley. That’s quite a lot of attain for a undertaking nonetheless early in its arc.

The project secured partnerships with AWS and UC Berkeley to build its decentralized AI training stack.

Supply: Sahara Labs

What raised our eyebrows much more was the word that Sahara’s already producing income on its information providers platform – and testnet customers are sharing in that. That’s not the standard “simply click on round and break stuff” strategy. They’re treating this testnet like a proving floor with actual financial circulation, not only a sandbox with coaching wheels.

Testnet users shared in real data revenue as Sahara trialed economic flows in its AI model layer.

Supply: Sahara Labs

Cash-wise, they’re effectively armed. $43 million raised from a stacked listing: Pantera, Polychain, Binance Labs, Samsung Subsequent, and extra. So there’s actual institutional perception right here – and doubtless a good bit of stress to ship.

However look, the reality is, that is uncharted territory. There are very actual, very messy questions sitting underneath all this: How do you really show a mannequin used a selected dataset? Who owns what if the coaching information got here from half the web? Can you actually construct a royalty circulation for AI that doesn’t crumble underneath gasoline prices or authorized scrutiny? None of that’s trivial, and none of it’s solved but.

Additionally price flagging: no mainnet, no token, and among the heavier logic (like licensing vaults and payout flows) continues to be extra idea than code. So whereas it feels massive – and it’d prove massive – proper now it’s nonetheless early scaffolding. An enormous moonshot, however a moonshot all the identical.

Wrap-Up

So yeah – Could had some attention-grabbing dynamics to it. Mainnets shipped, testnets went public, and some tasks reminded us that underneath the noise, persons are nonetheless constructing wild, formidable issues. Let’s be sincere: a few of this may flop, in the end. Some tasks would possibly quietly underpin the following cycle of truly helpful infrastructure. And a few… effectively, we’ll be again in a number of months to see if any of it caught.
