USDCx: Privacy or Just Another Folly?

One gathers the financial world is perpetually searching for the next Big Thing. Now it seems privacy – that quaint notion so beloved of the discreet and the disreputable – is being touted as the key to unlocking, apparently, a further $1.22 trillion. One wonders if anyone has actually checked if this trillion is still there.

Circle, a name that inspires confidence in much the same way as a seaside fortune teller, has launched USDCx, a thing backed by USDC, for a platform called Aleo. As if one acronym weren’t enough.

“With USDCx on Aleo, businesses and users unlock privacy-preserving payments, interoperable onchain dollars, and confidential multi-party workflows.”

The language, naturally, is that of the prospectus. One can practically smell the desperation. New blockchains, eager to establish themselves as marginally less awful than the last, are all embracing “selective disclosure.” A rather euphemistic phrase, wouldn’t you agree? It suggests a degree of control that is unlikely to extend to preventing scrutiny when the tax man comes calling.

From Coinbase’s (presumably still extant) Base to Stripe’s Tempo, they’re all at it. Honestly, the sheer number of new “revolutionary” protocols is becoming exhausting. One longs for the days when finance was simply opaque, not actively disguised.

Zebec Network, an entity whose purpose remains, frankly, obscure, declared:

“Privacy is a feature, not a tradeoff. USDCx on Aleo is a meaningful step toward confidential, compliant on-chain dollars.”

Meaningful, of course. Everything is meaningful when marketing budgets are involved. But why now? And who, precisely, is clamoring for these “confidential” dollars?

Public vs private stablecoin growth

Apparently, the institutional whimsy of shuffling stablecoins amounted to $1.22 trillion over the last twenty-four months. A rather alarming sum to be shifting about with such abandon. Private settlement, however, merely totaled $624.4 million – a rounding error in the grand scheme of things. Railgun and Oxbow apparently accounted for the bulk of that, bravely attempting to inject a little mystery into a relentlessly transparent world.

Aleo suggests this represents “slow privacy adoption”, which is simply a polite way of saying “no one much cares yet”. But, naturally, this implies “massive upside potential”. It always does.

Drivers for privacy transfers

Public transactions, it seems, invite undesirable attention. Competitors snooping, adversaries plotting… the usual. One rather shudders to think what sort of villainy goes on in full view of the blockchain. More worryingly, there’s been a spot of kidnapping. Apparently, revealing one’s on-chain wealth can be… unhealthy. A Ledger co-founder, poor soul, was abducted in France. A truly regrettable incident. It rather puts the talk of “disruption” into perspective.

Transparent transfers can also, it appears, facilitate “market manipulation”. Wintermute, a firm whose name has a distinctly untrustworthy ring, is frequently mentioned in these contexts. The public record, it turns out, can be a liability.

Early attempts at privacy – Ethereum-based EY Nightfall, for instance – have seen adoption rates of 2-5%. A glimmer of hope, perhaps, but hardly a stampede.

Final Thoughts 

  • Circle, in a commendable display of optimism, has unleashed USDCx upon Aleo.
  • Private stablecoin settlements remain, for the moment, a negligible fraction of the overall market. One suspects they will remain so.
