A new XRP Ledger study says two or three extra peer connections per participating node can sharply raise the number of nodes a targeted attack must remove to disrupt modeled consensus.XRPL consensus depends on enough trusted validators receiving one another’s messages. A separate peer-to-peer network carries those messages between servers, so extra routes could keep validator traffic moving if an attack removes the network’s busiest hubs.The Aug. 26 arXiv paper tests random K-out augmentation. K is the number of new undirected edges each participating node creates to peers chosen uniformly at random.At 60% participation and K=2, the model’s quorum critical…

Michael Saylor has hinted Strategy may resume Bitcoin purchases after weeks without buying. Strategy has not bought BTC since June and recently sold some of its holdings. The company raised US$2.01 billion through MSTR share sales but kept the funds in reserves and cash. Bitcoin remains below US$80K as analysts watch for signs the bear market may be ending. After weeks of not buying any more Bitcoin for its reserves, a post by the founder and chairman of Strategy (formerly MicroStrategy), Michael Saylor, indicates that things might be about to change. On what used to be Twitter and is now…

More than 2 million ETH is waiting to enter Ethereum staking as the amount already staked reaches a record high.Ethereum’s validator activation queue held 2.059 million ETH at 12:37 UTC on Aug. 30, leaving a deposit joining the back of the line facing an estimated wait of about 35 days and 18 hours.The backlog comes as more than 42 million ETH, nearly 35% of the cryptocurrency’s supply, is already staked. Both measures have climbed to record highs, extending a broader increase in capital committed to Ethereum’s proof-of-stake system.Only 96 ETH was waiting in the validator exit queue at the same…

Polygon Labs said the Austin fork on the Bor client and the Kyoto fork on the Heimdall client fixed a batch of security and liveness flaws, including two denial-of-service paths in block processing. The most severe flaw gave attackers a permissionless way to force costly, correlated decode work across the whole validator set with a single crafted transaction, according to the Aug. 27 disclosure. Austin activated on mainnet Aug. 13 and Kyoto on Aug. 18, and Polygon said the flaws were addressed ahead of any exploitation on mainnet. Polygon Labs revealed on Aug. 27 that two hard forks already active…

CryptoQuant CEO Ki Young Ju believes Bitcoin’s 2026 bear market has ended, citing a positive market-cycle indicator. Bitcoin has surged over 23% in two weeks, though it’s currently struggling to hold the US$80K mark. US Bitcoin ETFs saw their first outflows in nearly two weeks, led by Ark’s ARKB. As we wrote several times last week, analysts are currently following the crypto market closely to see whether there are signs the bear market is over. However, one analyst, CryptoQuant CEO Ki Young Ju, has made up his mind. On X (formerly Twitter), he posted: Ki Young Ju says Bitcoin’s 2026…

Leveraged funds more than doubled their CME XRP net short as open interest surged nearly 40% in one week.Last week, the Commodity Futures Trading Commission (CFTC) reported that XRP open interest increased by 2,206 from a week earlier, to 7,783 futures-equivalent contracts. At 50,000 XRP per standard contract, the increase represented about 110.3 million tokens and lifted total exposure to roughly 389.2 million XRP.The expansion came during a sharp recovery in the token. CryptoSlate previously reported that the digital asset had rebounded about 32% from $1 this month, trading near $1.38 as of press time.Leveraged funds moved against that momentum,…

Ripple’s roadmap, published April 20 by senior director of engineering Ayo Akinyele, schedules candidate post-quantum signature schemes to run alongside elliptic-curve signatures on the XRP Ledger’s Devnet in the second half of 2026. The plan targets a network-wide amendment and full transition to post-quantum cryptography no later than 2028, with partner Project Eleven building a hybrid signing prototype and a quantum-safe custody wallet. A “Q-Day” contingency would force what Ripple calls a hard shift, with classical signatures no longer accepted by the network and all funds moved to quantum-safe accounts. Ripple is working through a four-phase plan to ready the…

A $20 gold pattern with only five known examples will take center stage in Heritage Auctions’ ANA U.S. Coins Signature Auction, scheduled for Aug. 31 through Sept. 5. 1879 Liberty Head Quintuple Stella Judd 1643 Pollock 1843 The 1879 Liberty Head Quintuple Stella, Judd-1643, Pollock-1843, is graded PR64+ Deep Cameo by PCGS and comes from the Bob R.

Circle’s wrapped Bitcoin product entered the market with unusually strong institutional credentials and almost no visible scale.The company paired cirBTC with segregated reserves, a federally supervised custodian, direct minting and redemption for eligible businesses, and the distribution infrastructure behind USDC. Circle’s Aug. 27 reserve panel nevertheless showed just 40.02450077 cirBTC outstanding about 11 weeks after its Ethereum launch.The same panel showed 42.5114162 BTC in reserve, equal to about 106.2% coverage and a 2.48691543 BTC cushion across 14 disclosed Bitcoin addresses. The reserve cushion settled the backing question at that snapshot. The 40-token float exposed the harder problem: Circle had built…

Stablecoin demand is becoming consequential in the U.S. government debt market, but the maturity of that demand matters more than the headline total.Washington now has two debt-market stories running at once. The federal framework for permitted payment stablecoins channels reserves into cash-like instruments and Treasuries with no more than 93 days remaining. Farther out on the curve, the Treasury Department said on Aug. 19 that it would at least double the maximum size of liquidity-support buybacks in the 10- to 20-year and 20- to 30-year nominal sectors beginning Sept. 9.Together, those developments test a broad claim about digital dollars funding…
