Architecture, milestones, investor landscape, investment framework, future dominance, and forward roadmap across the three dominant Layer-1 networks.
The blockchain infrastructure landscape has matured from a single-asset experiment into a multi-chain ecosystem supporting trillions of dollars in value. This report provides a comparative analysis of the three most consequential Layer-1 blockchain networks: Bitcoin[1], Ethereum[2], and Solana[3].
Rather than viewing these chains as competitors, Salud Capital frames them as complementary layers of the decentralized internet stack — analogous to how the internet evolved from foundational transport (IP) to programmable protocols (TCP/HTTP) to consumer application frameworks. Investing across all three provides diversified exposure to distinct risk/return profiles within a coherent investment thesis.
Bitcoin is digital gold. Ethereum is the programmable finance substrate. Solana is the performance-first consumer internet layer. Together they constitute the core trilogy of blockchain infrastructure investment — and together they are increasingly being treated that way by sovereign institutions, sovereign wealth funds, and the world's largest asset managers.

Understanding who owns, develops, and advocates for each chain is essential context for evaluating long-term investment durability. Bitcoin's institutional base is the most organic and decentralized; Ethereum's is the most deeply networked into DeFi and institutional finance; Solana's is the most VC-concentrated but also the most directly tied to performance infrastructure and consumer application development.
Strategy (Michael Saylor) holds 500,000+ BTC — ~2.4% of total supply — making it the largest corporate BTC holder globally.[5] Block (Jack Dorsey) holds BTC and actively funds Bitcoin development via Spiral. Tesla retains a partial BTC position following its 2021 purchase.
BlackRock's IBIT became the fastest ETF to reach $10B AUM in history. Combined BTC ETF AUM surpassed $120B by April 2026.[6] 11 spot ETFs approved January 2024 — the most significant institutional legitimization event in Bitcoin's history.
El Salvador adopted Bitcoin as legal tender in September 2021.[7] Bhutan has been quietly mining BTC using hydroelectric power. Multiple U.S. states passed Bitcoin reserve bills in 2025; U.S. Strategic Reserve legislation advanced in Congress.
Peter Thiel's Founders Fund and Pantera Capital (Dan Morehead) were early institutional Bitcoin advocates. Blockstream (Adam Back) builds Liquid sidechain and satellite infrastructure.[8] Lightning Labs is backed by a16z and builds the LND Lightning client.
The Ethereum Foundation holds ~$1.6B in treasury (mostly ETH) and funds research, client development, and ecosystem grants.[9] ConsenSys (MetaMask, Infura, Linea L2) is the dominant commercial entity building Ethereum infrastructure with $700M+ in venture funding.
a16z crypto has deployed $7B+ across Ethereum-native investments (Uniswap, Compound, Optimism, OpenSea).[10] Paradigm (Huang/Ehrsam) co-invented DeFi primitives and is the most technically-engaged VC in Ethereum. Coinbase's Base L2 is backed by Coinbase's $6B+ balance sheet.
BlackRock's BUIDL tokenized money market fund surpassed $500M AUM on Ethereum in 2024.[11] Franklin Templeton's FOBXX fund is tokenized on-chain. JPMorgan's Onyx uses EVM-compatible infrastructure. Spot ETH ETFs approved July 2024.
Ethereum's L2 ecosystem is backed by billions in VC capital. Offchain Labs raised $120M (a16z, Lightspeed); OP Labs raised $150M (Paradigm, a16z); StarkWare raised $100M at $8B valuation.[12] Coinbase's Base has no external VC — leveraging Coinbase's $6B+ balance sheet and 100M+ users.
Yakovenko (CEO) and Gokal (COO) lead Solana Labs. The Solana Foundation manages ecosystem grants and the Superteam developer network across 30+ countries.[13] The Foundation's community programs are among the most geographically distributed developer programs in the industry.
Multicoin Capital (Kyle Samani) was Solana's earliest institutional advocate, publishing detailed theses in 2018.[14] Jump Crypto is building Firedancer — the second production validator client. FTX/Alameda's $200M+ SOL position was liquidated post-collapse; the supply overhang has largely been absorbed by 2026.
Franklin Templeton and VanEck received SEC approval for Solana spot ETFs in February 2025.[15] Visa extended USDC settlement to Solana in September 2023; Stripe re-enabled SOL payments in 2024. These TradFi partnerships validate Solana as production-grade payment infrastructure.
Helium (200M+ raised; Tiger Global, Union Square Ventures) migrated to Solana in 2023.[16] Render Network (GPU compute) migrated from Ethereum to Solana in late 2023. These DePIN protocols represent Solana's strongest real-world utility argument and are collectively a $3B+ TVL ecosystem.
Bitcoin was introduced on October 31, 2008 by Satoshi Nakamoto in a nine-page whitepaper proposing a trustless peer-to-peer electronic cash system.[1] The Genesis Block was mined on January 3, 2009. Bitcoin's security rests on SHA-256 Proof-of-Work — miners compete to solve hash puzzles, with difficulty adjusting every 2,016 blocks (~2 weeks) to maintain a ~10-minute block time. The November 2021 Taproot upgrade added Schnorr signatures and enhanced scripting via MAST, laying groundwork for the BitVM programmability expansion.[17] The Lightning Network (proposed 2015, launched 2018) enables off-chain micropayments at sub-cent cost with 60,000+ active channels and 5,000+ BTC capacity as of April 2026.[18]
Ethereum was conceived by Vitalik Buterin in 2013 and launched on July 30, 2015, with an initial crowdfund raising ~$18.4M.[2] The EVM — Ethereum's quasi-Turing-complete virtual machine — has become the dominant smart contract standard, with 30+ chains implementing EVM compatibility. The Merge (September 15, 2022) transitioned Ethereum from PoW to PoS, reducing energy consumption by 99.95% and ETH issuance by 90%.[19] EIP-1559 (August 2021) introduced a base fee burn mechanism — over 4.5M ETH destroyed since activation, creating ETH's deflationary supply dynamics.[20] EIP-4844 (Dencun, March 2024) introduced blob transactions, reducing L2 fees by 90%+.[21]
Solana was founded by Anatoly Yakovenko (former Qualcomm engineer) who published the Proof-of-History whitepaper in November 2017.[3] PoH uses a SHA-256 VDF to create cryptographic timestamps for events without validator coordination — eliminating a major latency source. Solana's architecture combines eight innovations: PoH, Tower BFT, Gulf Stream (mempool-less forwarding), Sealevel (parallel execution), Turbine (block propagation), Cloudbreak (horizontal state), Archivers (distributed storage), and Firedancer (second validator client). Firedancer, developed by Jump Crypto, launched on mainnet in March 2026 — the most significant Solana infrastructure milestone since launch, targeting 1M+ TPS.[22] Token-2022 enables confidential transfers and institutional-grade token features.[23]

Each chain's future dominance is concentrated in structurally distinct categories. Understanding these non-overlapping dominance zones is key to constructing a diversified blockchain infrastructure allocation that captures value from multiple long-term secular trends simultaneously.
ETF products, custodial infrastructure, and regulatory clarity make BTC the only digital asset suitable for pensions, insurance companies, and sovereign wealth funds at scale.
5–15 nations expected to formally hold Bitcoin reserves within 5 years. El Salvador precedent, dollar weaponization concerns, and U.S. Strategic Reserve debate set the trajectory.[7]
Lightning Network will dominate ultra-low-cost global payments, especially in emerging markets. Streaming payments and machine-to-machine transactions are primary growth vectors.[18]
BlackRock, JPMorgan, and others are building on Ethereum precisely because its security, regulatory treatment, and liquidity depth are unmatched in the smart contract space.[11]
Ethereum leads RWA tokenization — McKinsey's $16T bull case TAM would make it the most consequential financial infrastructure upgrade in a generation.[29]
Ethereum's Danksharding roadmap makes it the settlement layer for 100+ L2 rollups processing billions of daily transactions — capturing value via blob fees and MEV as activity scales.[30]
Autonomous AI agents require micropayment rails executing in milliseconds at sub-0.001 cent costs. No other production-grade blockchain meets these requirements today.
$3B+ TVL across 15+ protocols. Helium, Render, Hivemapper, and GEODNET represent Solana's most durable real-world utility advantage.[16]
Visa and Stripe integrations, combined with Solana Pay and sub-cent USDC transactions, position Solana as the payment blockchain for emerging markets globally.[25]
