For years, Ethereum was the only serious smart contract platform. Its first-mover advantage and network effects seemed insurmountable. But during the 2020-2021 bull market, a new generation of Layer 1 blockchains launched with ambitions to dethrone Ethereum. Each took a different technical approach, but they shared a common pitch: Ethereum was too slow, too expensive, and too limited — and their platform was the solution.

Avalanche, launched in September 2020, promised high throughput and near-instant finality through a novel consensus mechanism called Avalanche consensus. Its architecture used three interlinked blockchains: the X-Chain for asset transfers, the C-Chain for smart contracts (EVM-compatible, making it easy to port Ethereum dApps), and the P-Chain for staking and validator coordination. Avalanche’s AVAX token reached a market cap of over $30 billion at its peak.

Polkadot, launched in May 2020, had a different vision: a network of interconnected blockchains called “parachains,” all secured by a central relay chain. Founded by Ethereum co-founder Gavin Wood, Polkadot promised to be the “internet of blockchains,” allowing different chains to communicate and share security. Parachain slots were auctioned off to projects, creating a whole sub-economy of Polkadot projects. DOT’s market cap briefly exceeded $50 billion.

Cosmos took yet another approach. Its vision was of many independent blockchains connected by the “Inter-Blockchain Communication” (IBC) protocol. Unlike Polkadot’s shared security model, Cosmos chains are sovereign — each has its own validators and consensus. The Cosmos ecosystem has spawned important chains like Terra (before its collapse), BNB Chain, Osmosis, and many others.

None of these Layer 1 competitors have actually dethroned Ethereum, but they’ve all carved out significant niches. Each has trade-offs: Avalanche prioritizes speed; Polkadot prioritizes cross-chain security; Cosmos prioritizes sovereignty. Together, they’ve created a multi-chain future where users move assets between different blockchains based on their specific needs. Ethereum remains the largest smart contract platform, but it’s no longer alone. The future of crypto will clearly involve multiple chains, each with different strengths, serving different communities and use cases.

The idea of a Decentralized Autonomous Organization (DAO) predates Ethereum. It appeared in crypto-libertarian writings as early as 2013 — the vision of a company, non-profit, or community organized entirely by smart contracts, with no central leadership and no legal structure. Members would hold tokens that represented voting rights. Decisions would be made by on-chain voting. Funds would be managed by code. It was a utopian vision of pure democracy.

The first major DAO was The DAO in 2016, which famously failed due to a hack (as covered in an earlier article). For years after that, the concept lay dormant. But in 2020-2021, DAOs came roaring back. Dozens of them launched, with varying degrees of decentralization and sophistication. Some governed DeFi protocols. Some were investment funds. Some were art collectives. Some were experiments in digital democracy.

MakerDAO was one of the most successful. Its MKR token holders vote on everything from which collateral types to accept to how much to charge in fees. Uniswap has a DAO that governs its protocol. Compound has a DAO. Aave has a DAO. These DeFi DAOs manage billions of dollars in assets and make real governance decisions through on-chain voting.

But DAOs weren’t limited to DeFi. ConstitutionDAO emerged in November 2021 with a wild goal: raise money to buy a copy of the U.S. Constitution at auction. Within five days, anonymous crypto users had contributed over $47 million. ConstitutionDAO lost the auction to Citadel CEO Ken Griffin, but the experiment proved that DAOs could mobilize huge resources around shared goals. Thousands of people who had never met coordinated millions of dollars in days.

DAOs have struggled with real challenges. Voter participation is often low — most token holders don’t vote. Decision-making can be slow and contentious. Legal status remains unclear in most jurisdictions. And fully autonomous DAOs have often proven less effective than those with some human leadership. Despite these challenges, DAOs continue to proliferate and evolve. By 2024, thousands of DAOs existed, collectively managing tens of billions of dollars. They represent a genuine experiment in new forms of human coordination, made possible by blockchain technology.

In 2017, two Brown University graduates — Devin Finzer and Alex Atallah — launched OpenSea, a marketplace for buying and selling NFTs. At the time, NFTs were barely a thing. CryptoKitties had gone viral briefly in late 2017, but most crypto people considered NFTs a curiosity rather than a serious category. OpenSea would bet everything on NFTs becoming something bigger.

For three years, OpenSea was a small operation with a tiny user base. The founders lived off investor money and slowly built infrastructure for a world that didn’t really exist yet. They added support for more NFT standards. They built features for collectors to browse and trade. They made the buying process simpler. Progress was incremental, and the market was small.

Then came 2021, and everything changed. The Beeple auction in March sparked mainstream interest in NFTs. Bored Apes and other profile picture projects exploded. Overnight, OpenSea went from processing millions in monthly volume to billions. By August 2021, OpenSea was handling $3 billion in monthly trading volume. The company raised funding at a $13 billion valuation. The founders became billionaires. Employee count grew from a handful to hundreds.

OpenSea became the de facto eBay of NFTs. If you wanted to buy a Bored Ape, a CryptoPunk, or any of thousands of other NFTs, OpenSea was where you went. It listed every major collection, had an intuitive interface, and handled the complex smart contract interactions behind the scenes. At its peak, OpenSea had over 70% market share of all NFT trading.

The company also had problems. Insider trading scandals rocked OpenSea in 2021, with executives accused of buying NFTs they knew would soon be featured on the homepage. The 2022 bear market crushed NFT trading volume — OpenSea’s monthly volume dropped 95% from its peak. Competitors emerged: Blur, a pro-trader marketplace, took significant market share. OpenSea laid off staff and struggled to find its identity. By 2024, OpenSea was still the largest general NFT marketplace, but its dominance had been permanently broken. Still, its role in history is secure: OpenSea made NFT trading accessible to millions of people and proved that there was real demand for a marketplace of digital collectibles.

In 2018, a Vietnamese-Australian developer named Nguyen Thanh Trung and his team launched Axie Infinity, a blockchain-based game inspired by Pokémon and Tamagotchi. Players collect, breed, and battle creatures called Axies, each represented by a unique NFT on the Ethereum blockchain. The game had a small but dedicated community until 2021, when something remarkable happened: Filipino workers, left unemployed by COVID-19, discovered they could earn more playing Axie than working regular jobs.

The “play-to-earn” economics worked like this: players earned Small Love Potions (SLP), a cryptocurrency, by winning battles. They also earned AXS tokens, Axie’s governance currency. Both could be sold on crypto exchanges for real money. At peak, a skilled player could earn $50-100 per day — more than the average Philippines salary. Entire villages in rural Philippines turned to playing Axie as their primary income source.

The scale of Axie’s success was staggering. By mid-2021, the game had over 2 million daily active users. Its native token AXS reached a market cap of over $10 billion. The “scholarship” system emerged: wealthy Axie holders would lend their Axies to players who couldn’t afford to start, in exchange for a cut of the earnings. This created an entire economy of scholars, managers, and guilds — a pyramid-like structure where the top earned a significant percentage of everyone below them.

But Axie’s economy depended on constant influx of new players buying Axies to start playing. When new player growth slowed in late 2021, the economics began breaking down. SLP supply kept growing while demand for Axies fell. SLP prices crashed, then AXS prices crashed. Daily earnings for scholars dropped from $50 to $5 to almost nothing. Millions of Filipino players suddenly couldn’t pay their bills.

Then came the killing blow: in March 2022, hackers exploited a bug in Axie’s Ronin bridge and stole $625 million in assets — one of the largest crypto hacks ever. Axie Infinity survived but was permanently damaged. The play-to-earn model as a whole fell out of favor. But Axie’s legacy is important: it proved that blockchain games could attract millions of users, that NFTs could have real utility beyond profile pictures, and that crypto could meaningfully impact the economic lives of people in developing countries — for better and for worse.

By 2021, Ethereum had a serious problem: success was killing it. The DeFi boom and NFT craze drove massive demand for Ethereum transactions, pushing gas fees to painful levels. Simple token swaps cost $50 or more. Complex DeFi operations cost hundreds. For many use cases, Ethereum had become economically unviable. The solution was Layer 2 — a set of technologies that process transactions off the main Ethereum chain but still inherit Ethereum’s security.

The leading Layer 2 approach is called “rollups.” Rollups bundle many transactions together off-chain, compute the results, and then post a small proof to Ethereum’s main chain. The main chain only needs to verify the proof, not re-execute every transaction. This dramatically increases capacity while keeping costs low.

Two main types of rollups emerged: Optimistic Rollups (used by Optimism and Arbitrum) and Zero-Knowledge Rollups (used by zkSync, Starknet, Polygon zkEVM, and others). Optimistic rollups assume transactions are valid unless challenged; ZK rollups use cryptographic proofs to guarantee validity. Both have tradeoffs, and both are being developed in parallel by different teams.

Optimism launched its mainnet in December 2021. Arbitrum launched shortly after. Both quickly accumulated billions of dollars in value as users migrated from Ethereum mainnet to save on gas fees. By 2023, the combined total value locked on Layer 2s exceeded $10 billion. The ecosystem expanded rapidly, with hundreds of dapps deploying to multiple L2s simultaneously.

The Layer 2 era transformed Ethereum from a congested, expensive network into a multi-layered ecosystem. The main Ethereum chain (Layer 1) became the secure settlement layer. Layer 2s became the places where users actually transact. Over time, Ethereum’s vision evolved: rather than scaling the main chain itself, the ecosystem would scale through layers. This was controversial — some argued it fragmented the Ethereum experience — but it was working. Fees dropped dramatically. Users returned. By 2024, most Ethereum activity happened on Layer 2, with Layer 1 serving as the final settlement layer for the entire ecosystem.

Every four years, Bitcoin undergoes a programmed event called the “halving” — the block reward paid to miners is cut in half. This mechanism, built into Bitcoin by Satoshi Nakamoto in 2008, is one of the most important features of the cryptocurrency. It ensures that new Bitcoin supply gradually decreases over time, eventually stopping altogether when the total supply reaches 21 million. Halvings are scheduled events, but their impact on Bitcoin’s price has been profound.

The first halving occurred on November 28, 2012, reducing the block reward from 50 BTC to 25 BTC. At the time, Bitcoin was trading around $12. Over the next year, Bitcoin rose to over $1,200 — a 100x increase. The second halving occurred on July 9, 2016, reducing the reward from 25 BTC to 12.5 BTC. Bitcoin was at $650. Over the following 18 months, it reached $20,000 — a 30x increase. The third halving occurred on May 11, 2020, reducing the reward to 6.25 BTC. Bitcoin was at $8,500. Over the next year, it reached $69,000 — an 8x increase.

Each halving has been followed by a major bull market. This consistent pattern has led some analysts to propose a model called “Stock-to-Flow,” which predicts Bitcoin’s price based on its scarcity. The model has been surprisingly accurate across multiple halvings. Critics argue that the model is a coincidence or a self-fulfilling prophecy, but believers point to its track record as evidence that Bitcoin’s price action is predictable over long timeframes.

Whatever the mechanism, the halvings have reinforced Bitcoin’s narrative as “digital gold.” Gold is valuable in part because its supply grows slowly and predictably — the total gold supply increases by about 1.5% per year. Bitcoin’s halvings progressively reduce its supply growth rate. Before the first halving, Bitcoin’s annual inflation was about 25%. After the 2024 halving, it was below 1%. Bitcoin was becoming harder money than gold itself.

The fourth halving occurred on April 20, 2024, reducing the block reward to 3.125 BTC. Bitcoin was at $64,000 at the time. In the months that followed, the Bitcoin ETFs continued absorbing supply while the halving reduced new issuance. By late 2024, Bitcoin crossed $100,000 for the first time. The halving cycles will continue until roughly the year 2140, when the last Satoshi will be mined. By then, Bitcoin will have completed one of the most elegant monetary experiments in history — a currency with supply perfectly predictable and ultimately finite.

For over a decade, the crypto industry had been trying to get a Bitcoin Exchange-Traded Fund (ETF) approved in the United States. An ETF would allow traditional investors to buy Bitcoin exposure through their regular brokerage accounts, without needing to deal with cryptocurrency exchanges or wallet management. It would open Bitcoin to trillions of dollars of institutional capital. The SEC had repeatedly denied these applications, citing concerns about market manipulation and custody.

The first Bitcoin ETF proposal was filed by the Winklevoss twins in 2013. It was denied. In the years that followed, dozens of other applications were submitted. All were denied. Grayscale’s attempt to convert its GBTC trust into an ETF was denied in 2022. Grayscale sued the SEC, and in August 2023, a federal court ruled that the SEC’s denial was “arbitrary and capricious.” The writing was on the wall.

On January 10, 2024, the SEC finally approved 11 spot Bitcoin ETFs simultaneously. BlackRock’s iShares Bitcoin Trust (IBIT), Fidelity’s Wise Origin Bitcoin Fund (FBTC), and nine others began trading the next day. The approval had been preceded by months of speculation, with Bitcoin’s price rising in anticipation. The actual launch was almost anticlimactic — the ETFs went live, investors bought them, life continued. But the long-term implications were enormous.

The ETFs quickly became one of the most successful product launches in financial history. Within a few months, they had accumulated over $50 billion in assets. By the end of 2024, that number exceeded $100 billion. BlackRock’s IBIT became one of the fastest-growing ETFs ever. Traditional financial advisors, who had previously refused to discuss Bitcoin with clients, now had an easy way to add crypto exposure to portfolios.

The ETF launch triggered a new Bitcoin bull market. From around $43,000 at launch, Bitcoin climbed to over $100,000 by late 2024. Institutional buying was a major driver. Every day, the ETFs collectively bought thousands of bitcoins, creating sustained buying pressure. The “digital gold” narrative was finally being validated at an institutional level. For Bitcoin believers who had waited years for this moment, it was a triumph. For skeptics, it was proof that the system had absorbed what it had tried to reject. Either way, January 10, 2024 marked Bitcoin’s full acceptance into the traditional financial system.

The collapse of 2022 brought intense regulatory scrutiny to the crypto industry. The U.S. Securities and Exchange Commission (SEC), under Chairman Gary Gensler, took the most aggressive enforcement stance in crypto history. Gensler, who had taught a cryptocurrency class at MIT before joining the SEC, held a strong view: most cryptocurrencies were unregistered securities and their issuers were violating federal securities laws.

The SEC’s theory rested on the Howey Test, a 1946 Supreme Court decision that defines what counts as an “investment contract” and therefore a security. Under Howey, an investment is a security if it involves (1) an investment of money (2) in a common enterprise (3) with an expectation of profit (4) derived from the efforts of others. Gensler argued that most cryptocurrency tokens met all four criteria — and therefore needed to be registered with the SEC before being sold to U.S. investors.

Throughout 2022 and 2023, the SEC filed lawsuit after lawsuit. Ripple was sued over XRP sales (and partially prevailed in court). Coinbase was sued for operating as an unregistered securities exchange. Binance was sued alongside its CEO. Kraken was sued over its staking service. Various ICO projects were sued for unregistered token sales. The legal fees for defendants totaled hundreds of millions of dollars.

The crypto industry fought back. Coinbase launched a campaign called “Stand With Crypto,” mobilizing users to contact Congress. Industry groups argued that the SEC was regulating by enforcement — using lawsuits to create new rules rather than issuing clear guidance. They pointed out that the SEC had refused to write specific crypto rules even as it aggressively enforced vague interpretations of old laws. Some of the lawsuits resulted in mixed court outcomes, with judges sometimes siding with crypto defendants on specific issues.

The Biden administration’s crypto policy was generally hostile. “Operation Choke Point 2.0” was a term crypto advocates used to describe what they saw as an effort to cut crypto companies off from banking services. Banks that had served crypto clients, like Silvergate and Signature, collapsed in March 2023 amid regulatory pressure. Things improved somewhat after the 2024 election, when Donald Trump returned to the presidency promising a more crypto-friendly regulatory stance. Gary Gensler resigned. The SEC dropped some of its lawsuits. But the regulatory uncertainty of the 2022-2024 period had lasting effects, pushing much crypto innovation offshore and forcing U.S. companies to make difficult choices about where to operate.

If 2021 was crypto’s euphoric peak, 2022 was its brutal comedown. What began as a normal market correction in January 2022 gradually turned into one of the worst bear markets in crypto history. Bitcoin fell from $47,000 at the start of the year to $16,500 by November — a 65% decline. Ethereum fell even harder, from $3,700 to $1,100 — a 70% drop. Most altcoins fell 80-95%. The total crypto market cap went from $2.2 trillion to $800 billion.

The decline was driven by macroeconomic forces. The Federal Reserve, fighting the highest inflation in decades, raised interest rates aggressively throughout 2022. This made risk assets (including crypto) less attractive. Investors rotated out of speculative investments and into safer assets. Crypto, as the most speculative of speculative assets, fell hardest.

But 2022 was also a year of self-inflicted wounds. In May, the Terra/Luna collapse wiped out $60 billion and destroyed confidence in algorithmic stablecoins. In June, Three Arrows Capital (3AC), a major crypto hedge fund, revealed it was insolvent after losing on Terra and other bad bets. 3AC’s collapse triggered contagion through the crypto lending industry. Voyager, Celsius, and BlockFi — all major lenders — went bankrupt within months. Customers lost billions of dollars.

Then came November. FTX, the second-largest exchange in the world, collapsed in days. The fraud uncovered at FTX was far worse than anyone had expected. Sam Bankman-Fried, once crypto’s golden child, was arrested and charged with multiple counts of fraud. The contagion continued: BlockFi filed bankruptcy, Gemini froze withdrawals, and dozens of other companies reported exposure to FTX. Crypto’s reputation, already damaged by Terra, was further devastated.

Through all this, Bitcoin and Ethereum themselves kept working. The protocols functioned perfectly. Blocks were produced on schedule. Transactions were confirmed. But the ecosystem around them was in flames. For many, 2022 felt like the end of crypto. The projects that had seemed so promising in 2021 were dying one by one. The exchanges that had seemed so reliable were failing. Fortunes were being lost. Faith was being shaken. And yet, as with every previous crypto winter, builders kept building. When the next cycle came in 2024, the builders would emerge stronger, with better products and chastened expectations. But 2022 had been a brutal year.

On September 15, 2022, Ethereum executed the most ambitious technical upgrade in blockchain history: “The Merge.” This upgrade transitioned Ethereum from Proof-of-Work (the energy-intensive mining system used by Bitcoin) to Proof-of-Stake (a far more efficient system where validators stake ether as collateral). The transition had been planned for years and delayed multiple times. When it finally happened, it worked flawlessly.

The Merge reduced Ethereum’s energy consumption by approximately 99.95%. Before the Merge, Ethereum consumed as much electricity as a medium-sized country. After the Merge, it used as much electricity as a small town. This was a massive environmental win at a time when crypto was increasingly criticized for its carbon footprint. Environmental activists who had been hostile to crypto began viewing Ethereum differently.

Technically, the Merge was an extraordinary achievement. Imagine replacing the engine of a car while it’s driving down the highway at 100 mph — that’s roughly what Ethereum developers pulled off. The entire validator network had to coordinate a seamless transition between two completely different consensus mechanisms. Billions of dollars in assets depended on the switch working correctly. If it had failed, the consequences would have been catastrophic.

Proof-of-Stake also changed Ethereum’s economics. Under Proof-of-Work, miners received new ether for each block they mined — about 13,000 new ether per day. Under Proof-of-Stake, validators receive much less new ether — about 1,700 per day. This cut the new ether issuance by about 90%. Combined with a fee-burning mechanism (EIP-1559, implemented in August 2021), ether supply sometimes began decreasing rather than increasing. Ether had become a “deflationary” asset.

The Merge was a watershed moment that validated Ethereum’s roadmap and demonstrated that complex blockchain upgrades were possible. It also had strategic implications: Ethereum had moved away from Bitcoin’s approach and established itself as a fundamentally different kind of cryptocurrency. Bitcoin’s defenders argued that Proof-of-Work was superior for security. Ethereum’s supporters argued that Proof-of-Stake was more scalable and sustainable. Both sides had valid points. But the Merge settled one question decisively: Ethereum could evolve. It was not frozen in its 2015 design, but would continue to innovate and improve. That made it a more dynamic — and controversial — platform than Bitcoin.
