Everyone in crypto wants to build a trusted on-chain reputation without revealing personal data.

zkPass made this possible with its Verifiable Reputation Score (VRS) using zkTLS technology, which enables private, credible, and composable reputation building


TL;DR
VRS = an aggregated, auditable reputation score made from zero-knowledge proofs (zkTLS + other proofs) that prove a user’s off-chain footprints/external attestations without revealing personal data.Integrating VRS into Ethos would augment wallet score, social attestations, vouches, and reviews with privacy-preserving, cryptographic proofs — improving verifiability and sybil resistance while keeping private details secret.Implementation = zk proof generation off-chain → submit succinct zk proof + score delta on-chain → Ethos verifier contract updates a public reputation state (e.g., SBT or on-chain score).


What is VRS (quick definition)
VRS here = Verifiable Reputation Score: a numeric (or vector) reputation derived from multiple proof types (internet footprint verifications via zkTLS, social attestations, reviews, vouches, wallet behavior) where each input is accompanied by a zero-knowledge proof that the input is valid — but reveals only the minimal binding data (e.g., “I control this Twitter account” or “this email domain has these properties”), not the actual private identifiers.

How zkPass’s VRS (zkTLS proofs) would fit into Ethos

1) Inputs
zkTLS proofs from zkPass: prove statements about your internet footprint (e.g., control of an account, presence on a forum, ownership of an email domain, or action history) without disclosing identity details.Ethos inputs: wallet score, social attestations, review impact, vouches, transactional behavior.
2) Off-chain aggregation
User generates a set of zk proofs locally (or via a client) for each external claim (e.g., “I have 3 months of activity on forum X”, “I control twitter handle Y”).A reputation aggregator/relayer (or the user's client) composes these proofs and produces an aggregated VRS proof or discrete small proofs per attestation.
3) On-chain verification
Submit the zk proof(s) to an Ethos verifier smart contract (a zk-SNARK/zk-STARK verifier) that:Verifies the proof(s) cryptographically.Extracts the authorized score delta (or a compressed vector of reputation attributes) encoded in the proof’s public inputs.Updates the user’s on-chain reputation record (e.g., a reputation mapping or an SBT representing reputation buckets).
4) Score fusion
Ethos merges VRS deltas with existing signals (wallet score, vouches, reviews) using a transparent weighting policy (governed on-chain or by DAO).

Example data flow (step-by-step)
User connects an external service via zkTLS-authorized flow in zkPass client.zkPass client proves “I control X and met condition Y” to produce a zk proof (proof contains a public output like attestation_id + score_weight).Client sends the proof to a relayer that calls Ethos verifier contract with proof + user wallet address.Ethos verifier validates proof; on success the contract emits VRSUpdated(user, delta, source).Ethos scoring oracle recalculates consolidated reputation (on-chain) and stores it or mints/updates an SBT.

How zkTLS proofs strengthen trust while preserving privacy
zkTLS allows proving bound statements about TLS sessions or external service responses without revealing the session contents. Example proofs:“This wallet created and signed an account registration on forum X” (without revealing username).“This e-mail domain performed validations proving it’s a business domain” (without giving the actual e-mail).Because proofs are zero-knowledge, Ethos gets cryptographic assurance that the attestation is real, but no PII is disclosed on-chain or to third parties.
On-chain design patterns & technical pieces
Verifier contract(s): zk verifier(s) for proof types. Public inputs include address identifier + score delta or attribute vector.Reputation registry: mapping(address => ReputationStruct) or SBTs representing buckets (non-transferable).Attestation anchoring: optional anchor of attestation roots (Merkle roots) on-chain for auditability without leaking details.Relayer pattern: for gas abstraction, proofs submitted via relayers that can be sponsored.Rate-limits & replay protection: include epoch and nonce in public proof inputs to prevent replay.Upgradeability: keep scoring weights and verifier addresses upgradable via governance DAO.
Why it matters

Reputation is the missing layer in Web3.

With zkPass and Ethos, users could finally carry credible reputation across chains and platforms, built from proofs instead of profiles.
The future

Every verified proof, every vouch, and every impact review enhances your trust score, publicly verifiable and privately secured.
This is how Web3 builds trust without compromising privacy. 🔐✨

zkPass and Ethos together could become the standard for decentralized reputation, transparent, privacy-preserving, and truly owned by the user.

When the Central African Republic (CAR) made Bitcoin legal tender in 2022, it shocked the world. This small, landlocked nation, one of the least connected countries on Earth, had just leapfrogged into the crypto era.

President Faustin-Archange Touadéra promised to use blockchain to rebuild the economy. His government unveiled the Sango Project, an ambitious plan to digitize the nation’s resources and attract global investors.

But three years later, that dream has taken an unexpected turn, from a state-backed crypto revolution to a meme coin experiment that left investors scratching their heads.
🚀 The Sango Project: A Nation’s Crypto Dream


The Sango Project, launched in 2022, was presented as Africa’s boldest blockchain initiative.

Its goals were groundbreaking:


Make Sango Coin the official national digital asset.
Tokenize CAR’s natural resources such as gold, diamonds, and timber.
Offer land, e-residency, and citizenship through crypto investments.
Build a crypto island to attract developers and investors.

The vision was clear: turn CAR into a crypto hub of Africa.

But reality soon caught up.

The CAR Constitutional Court ruled that offering citizenship and land via crypto was unconstitutional.

The ICO saw poor participation and unclear tokenomics.

Internet penetration stood below 15 percent, limiting adoption in a country where most people still lack access to basic banking services.


By late 2024, the Sango Project had gone silent. Its once-active channels and communities dwindled, and investors were left waiting for updates that never came.

🪙 Then Came the Meme Coin
Just when observers thought CAR’s crypto story was over, President Touadéra made another unexpected move.
In February 2025, he posted on X (formerly Twitter) announcing the launch of a meme coin called $CAR, with the official account @CARMemecoinNews and contract address:
7oBYdEhV4GkXC19ZfgAvXpJWp2Rn9pm1Bx2cVNxFpump
In his post, he described it as “an experiment to unite people, promote national pride, and put the Central African Republic on the world stage in a new way.”
Within hours, the coin’s market cap reportedly surged to $900 million before crashing just as quickly.
What was meant to be a playful symbol of innovation suddenly turned into a global talking point about legitimacy, governance, and security.

⚠️ What Went Wrong


Investigations soon raised red flags:


The official website vanished shortly after launch.
The X account linked to the project was suspended.
Deepfake detection tools suggested the announcement video might have been AI-generated.
Observers noted the post was written in English, not French or Sango, and published at an unusual hour for the president’s timezone.

Whether it was a hack, an unauthorized stunt, or a mismanaged experiment, the result was the same: confusion among investors and embarrassment for the country’s leadership.


💬 Lessons for Emerging Markets


The story of Sango Coin and $CAR reveals both the promise and the peril of state-led crypto initiatives.


Transparency matters. Without public accountability and clear communication, investor trust evaporates.
Infrastructure comes first. Digital economies need reliable internet and regulation before tokenization.
Memes can move markets but not economies. A meme coin tied to national politics risks undermining legitimacy rather than building it.

While the CAR’s intentions may have been rooted in innovation, execution missteps turned what could have been a pioneering project into a cautionary tale for governments experimenting with crypto.



🔮 What’s Next?

President Touadéra is expected to seek a third term in the upcoming December 2025 election after constitutional changes extended presidential terms.
Whether the Sango Project or $CAR meme coin re-emerges as part of his campaign remains to be seen.
But one thing is clear: the world will be watching closely to see if the Central African Republic can turn its digital experiments into real economic transformation.
For now, both Sango Coin and $CAR remain suspended in uncertainty, powerful reminders that in the world of Web3, vision alone is not enough.

Augusta Finance opera come protocollo di rilascio di liquidità e punto di governance, saldamente integrato nell’ecosistema Velodrome Finance. Le sue soluzioni innovative consentono agli utenti di garantire prestiti istantanei garantiti da veVELO NFT, semplificando allo stesso tempo l'accesso al potere di governance di Velodrome Finance.

Comprendere la finanza Velodrome

Velodrome Finance costituisce un DEX ve (3,3) costruito sulla rete Optimism. Unisce la liquidità proveniente da vari protocolli sull'ottimismo tramite il meccanismo di corruzione veVELO. In quanto NFT, veVELO può essere trasferito tra individui attraverso il mercato NFT ufficiale della piattaforma, consentendo così ai titolari di ottenere molteplici fonti di reddito come commissioni di corruzione, commissioni di swap e rebase veVELO. Essendo l’attuale protocollo regnante all’interno dell’ecosistema dell’ottimismo, il potere di governance di Velodrome Finance equivale al controllo di una parte sostanziale di tutta la liquidità nell’ecosistema dell’ottimismo.

Augusta Finance punta a diventare il principale perno di gestione della liquidità nello spazio OP Stack, con il primo passo a partire da Velodrome. Ecco uno spaccato della metodologia di Augusta e del suo approccio strategico per affrontare le principali questioni.

In primo luogo, la modalità a strati convessi ampiamente utilizzata richiede il blocco dei veToken, che vengono poi convertiti in fatture di liquidità e utilizzati per formare un pool di liquidità del mercato secondario. Ciò risolve le complicazioni di liquidità e di interessi dei veTokens. Tuttavia, presenta anche degli svantaggi, come uno sconto sui conti di liquidità e una carenza di influenze esterne positive.

Meccanismo di consenso della prova dell'entropia-minima

- Proof-of-Entropy-Minima (PoEM) è un meccanismo di consenso utilizzato in Quai Network.

- PoEM si ispira al consenso Proof-of-Work di Nakamoto di Bitcoin.

- A differenza del PoW, PoEM misura il peso intrinseco del blocco per calcolare l'entropia e garantire l'accordo tra i nodi.

Vantaggi del PoEM

- Risoluzione istantanea del fork: tutti i nodi prendono sempre la stessa decisione sul blocco successivo.

- Finalità più rapida: PoEM offre una garanzia di inclusione on-chain più rapida rispetto ad altri meccanismi di consenso.
