On May 31, according to JIN10, Federal Reserve Governor Christopher Waller stated during a panel discussion at the 32nd Dubrovnik Economic Conference that the global proliferation of stablecoins could amplify the impact of Federal Reserve policy.
“For countries adopting stablecoins, it’s akin to operating under a fixed exchange rate regime.”
“You’ll be importing the U.S. monetary cost, so in countries where stablecoins are used more extensively, it effectively broadens the reach of U.S. monetary policy.”

Ripple architect says XRPL can go underground if states attack
Ripple CTO Emeritus David Schwartz has outlined how the XRP Ledger could respond if a state-level attack targeted validators, node operators or core network infrastructure. Schwartz made the comments during a discussion about whether a blockchain can survive pressure from an authoritarian state, specifically addressing what would happen if authorities started raiding nodes or forcing operators offline.
“I don’t think that would be very effective unless they could make it so that nobody was brave enough to run a validator. Operators would just be replaced. Validators could become anonymous and operate over Tor. But it would certainly be disruptive. If that actually did happen,…” He said intelligence services could create short-term disruption. However, he argued that long-term control would be harder because the XRP Ledger software, validator set and network structure can change when needed.
The idea has been described as a “Doomsday” approach for XRPL. It would not be a normal operating mode; instead, it would act as an emergency path if the network faced direct physical or legal attacks. Schwartz’s position centers on one point: a public blockchain can change its rules if users, developers and operators agree that survival requires it.
The proposed emergency setup would use privacy networks such as Tor and I2P to hide parts of XRPL’s consensus coordination. These tools could make it harder for authorities to identify and target operators. In that model, high-performance nodes would continue to process transactions. If attackers seized or disabled some nodes, reserve infrastructure could replace them. A second, lighter layer would help manage trusted validator lists, operating only when needed and using anonymous routing to reduce exposure.
The goal would be to keep consensus alive while lowering the chance that one government could identify all key participants at once. XRPL uses a Unique Node List model where each server follows validators it trusts not to collude. This differs from proof-of-work and proof-of-stake systems, where mining power or token stake often drives network security.
As previously reported by crypto.news, Schwartz recently said XRPL has more events that are “technically hard forks” than many older public blockchains, linking that pattern to the network’s upgrade model and its use of smart transactors. Separate coverage also detailed XRPL’s Negative UNL tool, a mechanism that allows the network to keep operating when trusted validators go offline or fail to perform properly. Those features matter because Schwartz’s emergency scenario depends on XRPL being able to replace or ignore damaged infrastructure without halting the network.
The comments come as XRPL continues to update its infrastructure, with the recent 3.1.3 upgrade including fixes for NFTs, Permissioned Domains, Vaults and the Lending Protocol. Schwartz has also addressed asset-control questions around Ripple’s RLUSD stablecoin. As reported by crypto.news, he said RLUSD can support settlement use cases but is not neutral because Ripple can freeze and claw back tokens under legal direction. That contrast adds context to the XRPL discussion.
XRP itself does not rely on an issuer that can freeze balances in the same way as a stablecoin. However, XRPL still depends on software, validators and user agreement. Schwartz’s “Doomsday” comments do not mean XRPL faces an active state attack; they show how one of its key architects thinks the network could react under extreme pressure.
Cardano Foundation cancels 2026 summit after treasury funding vote falls just short
The Cardano Foundation confirmed on Saturday that its proposed Cardano Summit 2026 will not go ahead this year after an onchain vote to fund the event from the network’s treasury failed to pass. The Foundation said in a post on X that it would respect the outcome and begin winding down summit execution.
“Governance requires not only participation, but also a commitment to accept collective decisions,” the Foundation wrote. “The Cardano community has spoken and we respect the outcome.”
Voting closed Friday, May 29, on a revised proposal seeking 7.8 million ADA, worth roughly $2 million, to stage a two-day summit in Singapore on October 5–6. Yes votes drew 65.21% of participating delegated representative (DRep) stake, just short of the 66.67% supermajority that treasury withdrawals require to pass, and the action expired without being ratified.
By headcount, a majority of voting delegates supported the request, 135 in favor to 61 against, with 24 abstaining, and the Constitutional Committee approved it. But under Cardano’s rules, a simple majority is not enough, as treasury actions need roughly two-thirds of DRep stake behind them.
The measure was already a scaled-back version of an original 14.07 million ADA proposal (~$3.66 million) that bundled the summit with an EMURGO-run TOKEN2049 sponsorship. (EMURGO is the official commercial arm of the Cardano blockchain.) The Foundation later decoupled the two events, trimming the budget by more than 20% and adding audited fund management, milestone-gated payments, and an independent oversight committee.
Cardano founder Charles Hoskinson and Cardano Foundation CEO Frederik Gregaard each urged DReps to approve the revised proposal in the hours before voting closed. The Foundation itself, which holds voting power as a DRep, abstained from the summit vote, saying it wanted to avoid directing the outcome.
The decoupling ended up being a success, however. EMURGO’s separate TOKEN2049 proposal passed, meaning Cardano will retain a presence tied to the major Singapore crypto conference. The Foundation voted in favor of the decoupled TOKEN2049 Platinum Sponsorship proposal.
The cancellation lands amid a wider run of recent treasury fights in the Cardano community. Cardano’s delegated representatives have repeatedly pushed back on spending tied to Hoskinson, EMURGO, and Input Output Global this year, including a scaled-back IO funding package built around the Leios mainnet push.
ADA traded near $0.233 on Sunday, down about 5% over the past month, with the token ranked around 16th by market capitalization, per The Block’s Cardano Price page.

Today’s Market Pulse
Corporate Bitcoin adoption accelerates as institutional players deepen exposure, while regulatory focus sharpens on market integrity and stablecoin implications, signaling crypto’s transition from fringe to financial mainstream.
Key Themes
Corporate Bitcoin Adoption Deepens
Nakamoto, a Nasdaq-listed Bitcoin treasury company, revealed holding over 5,000 BTC while CEO David Bailey invested nearly $1 million to increase personal holdings by 191,000 shares. Concurrently, Michael Saylor teased Bitcoin Tracker updates, potentially signaling imminent disclosures of further accumulation. These developments underscore institutional conviction in Bitcoin as a treasury asset, with corporate entities leading the charge in legitimizing digital gold as a strategic reserve.
Regulatory Scrutiny Intensifies
The U.S. Department of Justice targeted insider trading on Polymarket, accusing a Google engineer of earning $1.2 million through illicit trades, highlighting regulators’ expanding enforcement perimeter. Simultaneously, Federal Reserve Governor Christopher Waller emphasized that stablecoin adoption would amplify Fed policy influence globally, effectively creating “fixed exchange rate regimes” for adopting nations. This dual approach—enforcement against market manipulation while acknowledging stablecoins’ monetary policy implications—signals regulators are developing nuanced frameworks for crypto’s integration into global finance.
Market Sophistication & Security Challenges
Sophisticated traders demonstrated directional betting prowess, with a single address securing $2.5 million in profits from BTC and ETH shorts despite $1.03 million losses on HYPE positions. However, the ecosystem faces persistent security threats, as evidenced by Gravity Bridge’s $5.4 million hack leading to service shutdown. These contrasting stories reveal a maturing market where sophisticated trading strategies emerge alongside persistent infrastructure vulnerabilities, demanding balanced risk management approaches.
RichSilo Verdict
Smart money should monitor corporate Bitcoin treasury announcements as potential catalysts for price discovery, particularly focusing on companies with significant holdings relative to market cap. Regulatory clarity on stablecoins remains a wildcard that could reshape cross-border payments, while the Cardano treasury vote outcome demonstrates how decentralized governance can impact project roadmaps. The convergence of traditional finance infrastructure with crypto-native innovation creates both opportunities and risks, demanding nimble positioning as institutional adoption accelerates.
