R to @ayubio: Enganaram você: data centers no Brasil não consomem água para refrigeração. O maior em operação no país usa a mesma água desde a inauguração há 6 anos recirculando num sistema fechado de tubos. Te explico aqui: https://www.youtube.com/watch?v=BzHlrpP6oa0

TREASURY, COMMERCE DEPT. DISPUTE STALLS US STRATEGIC BITCOIN RESERVE 16 MONTHS AFTER TRUMP ORDER
More than 16 months after President Trump signed an executive order creating a Strategic Bitcoin Reserve, the U.S. government has yet to designate a managing agency, publicly disclose its full Bitcoin holdings, or acquire any additional BTC.
At the center of the delay is a dispute between the Treasury Department and Commerce Department over which agency should oversee roughly 328,372 BTC, worth ...

The First Bitcoin Network Flood Attack
An anonymous attacker spent $49,000 jamming Bitcoin with junk transactions trying to prove that 1MB blocks couldn't survive real demand. The congestion was real. The argument lost anyway. Brief thread... 🧵👇

R to @daily_btc_lore: 2/9 - In the summer of 2015 the block size war was at full boil. Bitcoin Core developers wanted to hold blocks at 1MB and scale by other means. The largest Chinese pools, AntPool, F2Pool, BTC China, Huobi, and BW, had answered with a joint proposal to raise the limit to 8MB.

R to @daily_btc_lore: 3/9 - On July 7 the argument left the forums. An attacker running at least 10 automated wallets began pumping out dust transactions, each one packing 102 outputs of 0.0001 BTC. Every transaction was perfectly valid, economically pointless, and built to devour block space.

R to @daily_btc_lore: 4/9 - F2Pool tried to clean up by sweeping thousands of dust outputs into one giant transaction. It weighed 999.657 KB and filled nearly an entire block on its own. Regular nodes refused to relay anything that size, so F2Pool mined it into its own blocks directly.

R to @daily_btc_lore: 5/9 - Even the cleanup hurt. The giant sweep took over 20 seconds to verify, lagging block explorers across the network. Greg Maxwell stepped in with a fix: reuse identical signatures across the inputs, which made the sweeps highly compressible and fast to check.

R to @daily_btc_lore: 6/9 - The damage was measurable. Researchers later classified 385,256 transactions from those ten days as spam, roughly 23% of everything Bitcoin processed. The mempool swelled past 80,000 waiting transactions, average fees jumped 51%, and confirmation times stretched sevenfold.
