About Bitcoin
Bitcoin is a proof-of-work public chain with a hard cap of 21 million coins, replacing reliance on trusted intermediaries with hashpower consensus and open rules to serve as censorship-resistant money and a peer-to-peer payment network, with the Lightning layer handling small, high-frequency payments and mainnet rules maintained by community consensus rather than a corporate entity. It answers distrust of monetary issuance and intermediary clearing, using PoW consensus, difficulty adjustment and a UTXO ledger to keep rules predictable and node operation accessible.
The trade-off is surrendering throughput and Turing completeness for stable, decentralized rules. Its security model assumes an honest majority of hashpower, leaving mining-pool distribution a standing centralization debate, while institutional exposure runs mainly through ETFs and custodians and onchain settlement still leans on self-custody and Lightning, with the public-key address scheme placing safekeeping entirely on the user.
In October 2008, Satoshi Nakamoto published the Bitcoin whitepaper, proposing decentralized peer-to-peer electronic cash.
In January 2009, Bitcoin's genesis block was mined, opening the era of decentralized digital money.
In May 2010, the first real-world Bitcoin trade occurred: 10,000 BTC for two pizzas.
In November 2012, Bitcoin's first halving cut the block reward from 50 to 25 BTC.
In 2013, Bitcoin's price first crossed $1,000, drawing global attention and regulatory debate.
In August 2017, Bitcoin's SegWit activated, laying the groundwork for Lightning Network scaling.
In May 2020, Bitcoin's third halving cut the block reward to 6.25 BTC.
In 2021, Tesla and other firms added Bitcoin to their balance sheets, driving corporate adoption.
In September 2021, El Salvador made Bitcoin legal tender, the first national adoption.
In November 2021, Bitcoin's Taproot upgrade activated, enhancing privacy and smart-contract capability.
In January 2024, the U.S. SEC approved spot Bitcoin ETFs, bringing in large institutional flows.
In April 2024, Bitcoin's fourth halving cut the block reward to 3.125 BTC.
In December 2024, Bitcoin crossed $100K for the first time.
Spot ETF flows drove the tape: U.S. spot Bitcoin ETFs saw net outflows for three straight months from May to July 2026, with June's roughly $4.6 billion the worst of the year; August flipped to about $3.52 billion of net inflows as BTC rose roughly 25% that month, and September added about $2.65 billion, lifting total ETF net assets to $107.98 billion by month-end. October returned to net outflows of about $538.9 million through October 16.
Policy and macro: on September 15 the Senate blocked the CLARITY Act in a 49-50 procedural vote (60 votes needed), briefly pushing BTC below $75,000 before a rapid rebound; the Fed hiked 25 bps to 3.75%-4.00% the next day, and hot inflation data in mid-October revived expectations of another hike. Strategy sold 6,916 BTC over the summer, then resumed buying in September (950 BTC at an average of $79,670), taking its holdings to roughly 846,000 BTC.
Bitcoin's reference client Bitcoin Core 32.0 released on October 10, 2026, focused on performance and security: parallel transaction fetching speeds block sync by up to 3x and patches command-execution and memory-exhaustion bugs; a privacy fix merged on October 1 isolates "private broadcast" connections to prevent IP correlation.
Lightning Network adoption reached real milestones: Block enabled zero-fee local Lightning payments for roughly 4 million merchants, and Kraken reported a $1 million Lightning payment. The US is also advancing a strategic Bitcoin reserve framework.
Bitcoin's Future strategy and roadmap: Bitcoin's bottleneck has moved from cryptography to coordination: BIP-360 entered the official repository in February and BIP-361 in April proposed phasing out ECDSA and Schnorr, yet neither has an activation timeline, while roughly 34% of existing supply has already exposed public keys, including 1.7 million early P2PK coins (about 1.1 million attributed to Satoshi) that can barely migrate. Institutional capital is now intervening with money rather than votes - nine firms including BlackRock and Coinbase formed a three-year, $15 million Bitcoin security consortium and Galaxy added a $5 million programme, both explicitly declining to steer the protocol. Whether migration beats Q-Day depends on this funding-and-consensus path. Upgrade timing therefore rests on consensus among miners, node operators and custodians rather than any single core team.
Bitcoin has no corporate owner. Its creator, Satoshi Nakamoto, published the whitepaper in October 2008, mined the genesis block in January 2009 and handed over control before disappearing in April 2011; the identity has never been made public. Maintenance since then has fallen to Bitcoin Core's volunteers and funded developers, with code merged by maintainers collectively rather than by a CEO or board, and any change only taking effect once developers have argued it through and node operators adopt it.
Current maintainers include Ava Chow, Michael Ford, Hennadii Stepanov, Ryan Ofsky, Gloria Zhao and TheCharlatan, covering wallet, build, peer-to-peer and consensus modules. Wladimir van der Laan, long the lead maintainer, stepped down in 2023 and returned the keys to the group. Since then Brink and OpenSats have supported developers through employment and quarterly fellowships, while Chaincode Labs and Spiral keep resident researchers. Developers meet every two weeks, and newcomers start with code review before a maintainer nominates them for merge access.
