Bitcoin Cores hidden database just shrank by 40 GB – if you know how to trigger it

Bitcoin Core has merged a redesign of its optional transaction index that cut about 40 GB from the database in one contributors mainnet test. Operators using -txindex retain their existing indexes through an upgrade; capturing the full saving requires recreating the database.　　Related Asset Bitcoin #1 BTC · $79,754.94 24-hour change: up 1.14% 24H Up 1.14% 7D Up 11.34% 30D Up 25.87%　　Pull request #35531, merged into Bitcoin Cores master branch on Aug. 15, reduced the authors rebuilt mainnet txindex from about 66 GB to 26 GB. The roughly 61% reduction is confined to this optional index. Bitcoins blockchain and the rest of a nodes data directory remain outside the measurement.　　Related Product Bitcoin Core An open source project which maintains and releases Bitcoin client software　　The code is merged upstream. Stable binaries follow a separate release process, and Bitcoin Cores release index leaves the first version containing the change unspecified. Operators will need the migration notes for the release that ships it.　　How the smaller index works　　Bitcoin Cores -txindex option maintains a database for retrieving transactions by their full transaction ID. The old format stored each 32-byte transaction ID as a database key alongside transaction disk-position data.　　The redesign stores a much shorter lookup key:

Protocol upgrade decouples consensus from execution to solve scaling bottlenecks

High-performance blockchains often run into the same architectural limit, where the execution sits directly in the path of consensus. In a conventional synchronous model, validators must first execute the transactions inside that block to confirm the resulting state transitions are valid.　　The design keeps the network deterministic, but it also turns computation into a shared bottleneck. Whether they involve richer smart contract logic, cross-system coordination, or heavier state updates, the more complex the transactions are, the more the networks speed depends on how quickly validators can process them.　　The slowest computation on that path can end up constraining the pace of the entire system. Many networks have already spent years improving finality, networking efficiency and block propagation.　　Execution has become the next architectural constraint. Rather than only optimizing how quickly validators reach agreement, newer designs are starting to ask whether execution needs to remain inside the consensus loop at all.　　Shifting to an asynchronous computation pipeline　　CTDG Dev Hub participant MultiversX removes that constraint with Supernova, now live on testnet, by decoupling consensus from execution so the network can agree on blocks before processing their transactions.　　Before Supernova, block production followed a sequential pattern. A proposer selected transactions, executed them locally and proposed a block with

Better launches Bitcoin-backed mortgages powered by Coinbase

Better Mortgage and Coinbase have made their Bitcoin-backed mortgage product generally available, allowing US homebuyers to pledge Bitcoin as collateral for a down payment without selling it, the companies announced Wednesday.　　According to Coinbase‘s Help Center, the product pairs a Fannie Mae-backed home loan with a separate down payment loan secured by Bitcoin (BTC). Borrowers must pledge BTC worth at least 250% of the down payment loan, with the pledged BTC transferred to Better’s custodial account on Coinbase Prime.　　The two loans carry the same interest rate and amortization term and are repaid through a single monthly payment, Coinbase said. The pledged BTC is returned once the mortgage is fully repaid or refinanced, subject to the loan terms.　　Bitcoin price declines alone do not trigger margin calls or changes to the mortgage terms. However, Better can liquidate the pledged BTC if a borrower becomes 60 days delinquent on payments, according to Coinbase.　　Borrowers must be US residents with a verified Coinbase account, and remain subject to Betters credit, income and other underwriting requirements. Coinbase One members are also eligible for a 1% rebate from Better, subject to a $10,000 cap, that can be used toward closing costs and fees.　　Better and Coinbase first announced the

Biggest Bitcoin Catalyst Is Not the Halving: Will US Debt Drive BTC to $300,000？

Bernstein has set Bitcoin (BTC) targets of $150,000 by mid-2027 and $300,000 by 2029. The case rests on US government debt, not the halving. The biggest Bitcoin catalyst, the broker argues, now sits in the bond market.　　The timing is hard to ignore. US debt crossed $40 trillion this month, and a Treasury announcement, not a crypto headline, drove bitcoin from the mid-$60,000s to about $81,200 in a week.　　Sponsored　　Sponsored　　Why US Debt Is Now the Biggest Bitcoin Catalyst　　The US officially owes $40 trillion, a record it crossed on August 19. That figure has more than doubled in a decade.　　Bernstein analysts, led by Gautam Chhugani, argue in a new note that four decades of falling interest rates are over. Every rise in yields now feeds bigger deficits and heavier borrowing.　　Faced with that loop, Bernstein expects Washington to pick the quieter exit. Let the currency lose value instead of cutting spending. That path favors assets no government can print, like bitcoin and gold.　　The firms base case sees $150,000 by mid-2027 and roughly $300,000 at the 2029 cycle peak. If institutions move faster, Bernstein models $500,000 in 2029 and about $1 million by 2033.　　BITCOIN COULD HIT $300,000 BY 2029　　Bernstein predicts Bitcoin could recover to a

Americans Want Retirement Security, But Dont Trust Bitcoin to Deliver It

Most Americans do not want cryptocurrency near their retirement money, a new National Institute on Retirement Security (NIRS) survey shows. The poll finds 77% call crypto in retirement plans risky, and 46% say it is very risky.　　Eighty percent now say the US faces a retirement crisis, up from 67% in 2020. Meanwhile, 61% fear they will not be financially secure after they stop working.　　Sponsored　　Sponsored　　Retirement Anxiety Keeps Climbing　　Greenwald Research ran the survey of 1,203 US adults for the Washington-based nonprofit late last year. The results read like a warning.　　Inflation worries 73% of savers. Market swings trouble 62%. And 76% fear Social Security cuts if Congress fails to act.　　The savings numbers explain the fear. Nearly half of Americans have less than $100,000 put away. Another 18% have nothing at all.　　Even $100,000 buys less than most people think. Only 9% knew it produces roughly $4,000 in first-year retirement income under a standard withdrawal rule.　　“Americans are telling us that retirement security is becoming harder to achieve as they struggle with the affordability of everyday life. Housing, healthcare, debt and other expenses are competing with the need to save for retirement,” Dan Doonan, NIRS executive director, said in the report.　　Follow us on X to get
