Bitcoin
The first decentralized cryptocurrency, based on blockchain technology, characterized by cross-border circulation and pseudonymity. It is often used for fund transfers in online fraud.
Timeline (last 90 days)
Binance's platform token BNB may face selling pressure, while mainstream assets such as Bitcoin and Ethereum may also fluctuate in the short term due to market panic.
A project called "Steal My Bitcoin" was posted on Hacker News, in which the developer offered a Bitcoin bounty to test the exploitability of a PHP RCE vulnerability.
As of the article's publication, the "Steal My Bitcoin" challenge was still ongoing, and it is not yet known whether anyone has succeeded in taking the Bitcoin.
Attacking the Bitcoin network requires controlling more than half of the hash rate, and the cost rises in step with network size, so security itself becomes a continuously invested "sunk cost."
Proof of work (PoW) is Bitcoin's consensus mechanism: miners compete for the right to record transactions by repeatedly computing hash values, a process that consumes real electricity and hardware compute and whose results can be verified cheaply by the whole network.
Arthur Hayes recently said that generative AI models (such as OpenAI and Anthropic) may lack long-term intrinsic value, while Bitcoin is the ultimate winner.
Bitcoin converts physical energy into mathematical scarcity through proof of work (PoW), and its protocol rules are mathematically fixed and decentralized.
As autonomous transactions between AI agents increase, the need for a neutral, permissionless, tamper-proof settlement mechanism will become urgent, and Bitcoin is positioned precisely as the global decentralized settlement layer for this automated economy.
Bitcoin's supply cap is 21 million coins, and this cap is institutionally locked in without requiring any commitment from a central authority.
ECDSA relies on specific elliptic curve parameters, such as secp256k1 (the curve used by Bitcoin) and NIST P-256, etc.

50%UnverifiedMerkle trees are underlying infrastructure in Git, IPFS, Bitcoin, and Ethereum, and Ethereum's state root and transaction root are both Merkle Patricia trees.
50%UnverifiedBlockchain irreversibility comes from its consensus mechanism design: Bitcoin makes the computational cost of rollback rise exponentially as the number of confirmations increases; after Ethereum's Merge shifted to proof of stake, a finality mechanism ensures that confirmed blocks cannot be easily reorganized.
50%UnverifiedOpenTimestamps is a Bitcoin timestamping protocol proposed by Peter Todd that submits the SHA-256 hash of data to calendar servers, aggregates them into a Merkle tree, and writes it to the Bitcoin blockchain, providing an extremely low-cost, no-need-to-trust-a-single-server "not later than" proof of existence at a certain point in time.
50%UnverifiedThe Merkle tree is the underlying mechanism used by blockchain systems such as Bitcoin to verify transaction integrity.
50%UnverifiedSome researchers have noticed a significant surge in on-chain activity on the Bitcoin network around the time points when foreign aid funds were disbursed.
50%UnverifiedEvery Bitcoin transaction is permanently recorded on a public ledger, allowing researchers to track fluctuations in transaction volume, transaction frequency, and fund size within specific time windows.
50%UnverifiedBitcoin addresses do not carry identity information, so researchers must rely on address clustering techniques to infer groups of addresses controlled by the same entity.
50%UnverifiedBitcoin transactions are completed almost instantly, are irreversible, receiving addresses do not need to be linked to a real identity, and funds can be further obscured through mixers.
50%UnverifiedBitcoin on the blockchain cannot be forcibly retrieved through court orders or institutional intervention.
50%UnverifiedBitcoin Layer 2 payment solutions such as Lightning Network have compressed the cost per transaction to the sub-cent level.
50%UnverifiedThe cryptocurrency community advocates the philosophy of "Not your keys, not your coins."
50%UnverifiedProof-of-Work (PoW) was originally proposed as a concept to prevent email spam, and was later widely adopted by blockchain projects such as Bitcoin.
