Anduro

  • Name: Anduro
  • URL: https://www.anduro.io/
  • Category: merge-mined Bitcoin sidechain network / federated-peg infrastructure / miner-revenue-alignment Bitcoin app layer
  • Tags: bitcoin-ecosystem
  • Summary: Anduro is a Bitcoin sidechain program with miner-alignment marketing on top and federation-controlled peg reality underneath. The network pitch is merge-mined BTC expansion; the actual trust model still lives in sidechain-specific operators, peg signers, and sponsor control. Alys makes that plain. Useful comparison note, not some clean Bitcoin extension.
  • What it does:
    • Presents Anduro as a platform for launching multiple Bitcoin-connected sidechains rather than one monolithic chain
    • Frames those sidechains as merge-mined with Bitcoin and as using Bitcoin-pegged native assets, so miner incentive alignment is part of the product story from the start
    • Was launched publicly by Marathon Digital as an incubated network intended to become community-led and community-driven over time
    • Initially highlighted two sidechains with distinct roles: Coordinate for a more efficient UTXO stack for Ordinals and Alys for Ethereum-compatible asset tokenization
    • Exposes, through the Alys repository, a sidechain architecture where BTC is the base currency, consensus combines auxPoW from Bitcoin miners with a federation, and a two-way peg is handled by federation members
    • Reuses familiar EVM tooling in Alys via Geth-based execution while keeping the bridge / federation / miner-integration logic as separate sidechain-specific layers
  • Key claims:
    • The launch press release is unusually explicit that Anduro is meant to strengthen Bitcoin’s Proof-of-Work incentives by giving participating miners additional Bitcoin-denominated fee revenue from sidechain activity. That makes the miner-economics layer, not only smart-contract capability, central to the project’s identity.
    • The launch materials also make a distinction that is easy to lose in generic BTC L2 coverage: Anduro is a platform for multiple sidechains with different tradeoffs, not a single execution environment. Coordinate and Alys are already pitched as materially different chains rather than apps on one shared state machine.
    • Alys is the clearest architectural evidence in this pass, and it shows that merge-mining does not by itself remove intermediary trust. The README says Alys reaches consensus through auxPoW executed by Bitcoin miners and a federation, and that the two-way peg is facilitated through federation members. That means the real control surface sits partly with the federation even if Bitcoin miners provide part of the security story.
    • The Alys repo is also useful because it reveals a practical split between reused execution software and bespoke bridge logic. Alys uses Geth-compatible EVM tooling, but still relies on dedicated peg-in / peg-out flows, federation deposit addresses, and a bridge contract layer. That helps separate EVM compatibility from Bitcoin peg governance instead of treating them as one thing.
    • Marathon’s role matters analytically. The press release says Anduro is intended to become community-led, but Marathon incubated the network, announced the first sidechains, and tied the project directly to its own miner-revenue strategy. That makes sponsor influence and transition-to-community claims a real governance surface rather than background context.
    • The current Anduro site now emphasizes making Bitcoin quantum resistant and says quantum-resistant bridging is made possible exclusively by MARA Slipstream. That positioning drift is itself important: it suggests the network-level story may continue to move as Marathon’s broader product stack and differentiation strategy evolve.
    • Anduro clears the corpus bar because it sharpens a specific Bitcoin-sidechain comparison layer: merge-mined incentive alignment can sit at the network level while actual custody, peg policy, and execution authority remain chain-specific and operator-mediated.

The clearest parsed primary materials in this pass were the official site, Marathon’s launch release, and the Alys repository README; see ../whitepapers/anduro-primary-sources-2026-05-14.md.
