Is Siacoin still active in 2026?

Siacoin is active. The protocol upgraded in 2025. The foundation maintaining it is operational. Development is continuous. Coins trade on 60+ exchanges. The network produces blocks every ten minutes as it has since 2015. 'Active' doesn't mean 'making price headlines' — that's a different question, and the answer to that one is 'no, Siacoin isn't doing that right now.' But active and price-making are separate questions, and the conflation is most of why this post has to exist.

The Sia v2 hardfork activated on June 6, 2025 at block height 526,000. v2 introduced Utreexo-style accumulator proofs to the consensus layer, reducing the state-data requirements for running a full node and enabling the lite-mode sync that Sia Wallet now uses by default. Before v2, a full node needed to track the entire UTXO set — by 2025, that had grown to a size that genuinely impeded new-node onboarding. After v2, light clients can verify balance proofs without the full state, which makes wallets like Sia Wallet (and light clients broadly) feasible. The v2 Final Cut cleanup fork then activated on December 2, 2025 at block 552,100 — this finalised the v2 consensus rules, removed legacy code paths, and retired backward-compatibility scaffolding. The network as of April 2026 is running clean v2 consensus.

The Sia Foundation is a US-registered 501(c)(3) non-profit, domiciled in Massachusetts, established in 2021 to maintain the Sia protocol and core open-source software. It is funded by a perpetual Siacoin subsidy adopted by network hardfork in February 2021 — a portion of the block reward goes to a foundation address, which funds development, operations, and audits. The foundation publishes quarterly 'State of Sia' reports on sia.tech and maintains the walletd, renterd, and hostd repositories. Commits in the walletd repository are ongoing as of April 2026; the most recent production release tag at time of writing is within the last month. This is not a project in maintenance mode — it is a project with a funded team shipping code.

That said, Sia is a small project by cryptocurrency standards. The foundation employs a team of developers — low double digits, by public information. Community contributions flow in, but the core protocol work is primarily foundation-led. That profile is legible: Sia is a purpose-built decentralised storage network, not a smart-contract platform competing for developer attention. The right comparison is not to Ethereum or Solana — it's to a specialised protocol like Storj or Filecoin, or arguably to Monero in its focused-on-one-thing ethos. Within the storage-specific niche, Sia has continuous development, continuous protocol improvement, and a clear technical roadmap.

Siacoin circulating supply is approximately 56 billion SC as of April 2026. Supply continues to inflate via the proof-of-work block reward — Sia is an inflationary utility coin by design, not a fixed-supply store of value. Siacoin trades on approximately 60 exchanges, with the largest volume venues typically being KuCoin, Gate.io, MEXC, and HTX. The Exchange page on this site pulls live listing data from CoinGecko. Coinbase does not list Siacoin. Binance delisted Siacoin in 2021. Kraken does not list Siacoin. The absence of tier-1 US exchange listings is a real limitation — it makes price discovery thinner and onramp/offramp less convenient for US users — but it does not mean the network is inactive. Coins that trade on 60 exchanges are not dead coins; they are small-cap coins with a long tail of mid-tier listings.

Active doesn't mean the price is going up. It doesn't mean Siacoin is the best storage coin, the future of decentralised anything, or a good investment. Those are separate questions, and this project does not try to answer them — Sia Wallet is a wallet, not an advisory service. What active means, specifically, is: the protocol is upgrading, the foundation is funded and shipping, the network produces blocks, the coins trade, and users can self-custody and transact them. All of those things are true in April 2026. Whether you buy, hold, sell, or ignore Siacoin from here is your decision. Whether the network will still be here to transact on is not the question to worry about.

Self-custody it. Exchanges are counterparties whose security and solvency are not under your control. Sia Wallet v2.12.0 is the consumer-grade option — install it, back up the seed on paper, move your SC off the exchange. If you're still on Sia-UI, migrate: the built-in migration assistant handles the legacy-seed-to-v2 transition in one flow. If your holding is material, add a Ledger Nano for the signing layer. If it's treasury-scale, consider multi-signature. The tools for serious self-custody of Siacoin exist in 2026 — better than at any point in the project's history.
