DBS and Citi Move Weekend USD Payments in Minutes, Not Days

5 min read · 12 sources

TL;DR
  • DBS and Citi completed a weekend USD payment via tokenized deposits on Swift's Digital Ledger, settling in minutes versus two business days.
  • Ethereum's PeerDAS proposal cuts per-node blob reconstruction CPU time from 5.18 seconds to 40 milliseconds per slot, eliminating supernode requirements.
  • Wyoming's stablecoin (WYST) has 967,948 tokens in circulation, 0.2% of its 508.7 million projected supply, with just $160 in 24-hour volume.
  • Coldcard exploiters moved 45% of Wave 3 stolen bitcoin, swapping to ETH via THORChain and laundering through CoinJoin.
  • 600 BTC (~$48 million) from 16-year-old dormant wallets moved on-chain, with no confirmed link to Satoshi Nakamoto.

Ethereum’s PeerDAS proposal cuts per-node blob reconstruction CPU time from 5.18 seconds to 40 milliseconds per slot.

DBS and Citi Just Made Weekend Cross-Border Payments Look Easy

DBS and Citi completed a Singapore-to-US USD payment over a weekend using tokenized deposits on Swift’s Digital Ledger. The transaction settled in minutes, versus the one to two business days traditional cross-border transfers take when banks are closed.

This is the first weekend settlement of its kind, and it works because both banks issued tokenized versions of their deposits on a shared ledger. Citi joined Swift’s 24/7 tokenized payments pilot in July and is also part of a separate group of major US banks building a tokenized deposit network through The Clearing House, targeting a 2027 launch. The infrastructure is real, the rails are live, and the weekend is no longer a dead zone for settlement.

Ethereum's PeerDAS Proposal Kills the Blob Reconstruction Bottleneck

Ethereum researchers published a proposal to eliminate redundant blob reconstruction work that every qualifying node currently performs on its own. Under the present design, an estimated 2,000+ nodes each spend 5.18 seconds of CPU per slot reconstructing blobs, which is why only high-spec machines can keep up.

The PeerDAS architecture uses a two-dimensional cell matrix where column subnets retain custody of specific data slices. This cuts per-reconstructor time to 40 milliseconds and network-wide CPU from roughly 10,000 seconds to under 100 seconds per slot. A Prysm prototype with real KZG cryptography already exists, and a staged rollout variant preserves 91% of the CPU savings before full deployment.

The practical effect: you no longer need a supernode to participate in blob reconstruction. Ordinary nodes can do the work, which lowers the barrier to running a validator and reduces the concentration risk that comes from a small set of high-end operators.

Wyoming's Stablecoin Is Live, But Nobody's Using It

Wyoming’s official stablecoin (WYST) went live with Chainlink as its exclusive verification layer, providing Proof of Reserve for the state’s tokenized dollar. The supply stands at 967,948 tokens priced at $0.9988 each, which is 0.2% of the projected 508.7 million tokens.

The 24-hour trading volume is $160, all on Kraken. The Proof of Reserve Secure Mint component, which would let the state mint new tokens only when real dollars back them, is not yet active. Wyoming partnered with Chainlink in a month, following an August 18 migration from a previous provider. The infrastructure is in place, but a stablecoin with less than $1 million in circulation and triple-digit daily volume is a pilot, not a product.

Who Killed the Cryptoanarchist?

A personal essay traces the cryptoanarchy movement from its 2016 Toronto meetup roots through the 2020-2022 bull cycle, arguing that the ideology died when crypto companies prioritized institutional capital and mainstream UX over trust minimization. Each abandoned value has since been validated by AI-era behavior: users hide identities from AI scrapers, developers distrust closed-source models, and businesses treat every networked system as potentially hostile.

The piece argues that the movement’s core insight - that financial systems are downstream of social obligations - has become more relevant as AI concentrates power. A revival is possible under new banners, with AI-driven threat models replacing the old cypherpunk ones. For engineers, the lesson is that the tech was never just about money; it was about who gets to verify what.

The Shape of Ethereum: Six Years of Topological Anomalies

Researchers applied Topological Data Analysis to six years of Ethereum transaction data (2020-2025), segmenting daily activity into four layers and using Wasserstein distance to quantify structural changes between consecutive days. The method identified 86 anomalous days, with 73 (85%) correlating to real-world events.

Key findings include Black Thursday’s liquidation cascades, DeFi repositioning two days after the Ukraine invasion, and post-Bybit hack fund dispersal across bridges. Unsupervised change-point detection found six structural breaks, and the topological features improved 7-day ETH volatility forecasts beyond GARCH baselines. Notably, anomaly patterns shifted in 2024 from complex DeFi events (11 of 16) toward plain ETH transfers, suggesting the network’s activity profile is changing.

Coldcard Exploiter Moves 45% of Wave 3 Stolen Funds

The attacker behind the Coldcard hardware wallet exploit - a 2021 firmware bug that weakened seed randomness - has moved 45% of the Wave 3 stolen bitcoin, according to Galaxy Research. The funds were swapped to ETH via THORChain, then laundered through CoinJoin.

About $7.8 million has been spent so far, moving stolen vaults largest-first. The methodical, largest-first approach suggests a professional operation, not a panicked amateur. If you hold Coldcard funds from that era, this is a reminder that the clock is running.

Mapping Onchain BTC Credit Solutions

A survey of four approaches to bitcoin-backed credit without a centralized custodian: Babylon (a bridge structure mainly for CeFi lenders with a thin smart-contract layer), Komainu (a Nomura/Ledger/CoinShares JV using a legal “Notice of Exclusive Control” framework), and Concrete’s AssetCX (BitGo custody plus a real 1:1 ERC-20 synthetic usable as DeFi collateral).

Concrete is the most DeFi-native because it’s the only one built around an actual onchain token rather than a legal wrapper. The BTC never leaves its own chain via Taproot dual-spending paths, which means the collateral stays put while the synthetic moves. The trade-off is clear: legal wrappers are faster to deploy, but tokenized synthetics are composable.

MENA crypto volume hit ~$350 billion in 2025-2026, up from $200 billion in 2022. Recent US bank charter approvals mean banks are about to gain the same programmability and 24/7 settlement that DeFi protocols have relied on - they’re becoming direct competitors, not just gatekeepers. A crypto card update roundup covers the latest card launches and fee changes.

And 600 BTC (~$48 million) transferred from 12 addresses dormant for over 16 years, each holding proceeds from a single block reward mined in 2010. Lookonchain initially identified seven wallets moving 350 BTC. The tracking platform found no connection to Satoshi Nakamoto, though one reward moved as a test transaction before the others. The coins’ age and the lack of any Satoshi link tempers speculation about the pseudonymous creator - but 16 years is a long time for anyone to hold.
