+
+Utreexo is a project to shrink the state a Bitcoin node needs to carry. It
+replaces the full UTXO set with a small set of accumulator roots derived from a
+hash-based Merkle forest, while separate proofs show that a spend is valid. The
+codebase centers on the [`utreexo`](https://github.com/utreexo/utreexo)
+accumulator library and [`utreexod`](https://github.com/utreexo/utreexod), a
+full node and bridge node implementation that serves those proofs to peers.
+
+Bridge nodes matter because today's Bitcoin network relays blocks and
+transactions without Utreexo proofs. `utreexod` fills that gap, while related
+work in [Floresta](/projects/floresta) brings the same model to a Rust
+compact-state client. The broader effort also includes protocol specifications
+for the accumulator, validation rules, and peer-to-peer messages.
+
+## Why fund it?
+
+Running your own node works best when the hardware requirements stay within
+reach. The storage and disk I/O cost of the full UTXO set pushes many users
+toward hosted infrastructure or lighter clients. Utreexo cuts that cost and
+opens the door to compact-state nodes on phones, single-board computers, and
+other constrained devices while preserving full verification.
+
+OpenSats first funded Utreexo in the
+[fifth wave of Bitcoin grants](/blog/bitcoin-grants-july-2024#utreexo),
+supporting work on transaction messaging, BIP writing, and bridge-node
+implementation work.
+
+## What's next?
+
+Recent work landed in [`utreexod` v0.5.0][v0-5-0] and [`v0.5.1`][v0-5-1]. The
+current release line brings SwiftSync-based IBD, bridge-node performance and
+database work, and continued cleanup of the Utreexo wire protocol. In parallel,
+[BIP 181, 182, and 183][bips-pr] remain under review, covering the accumulator,
+validation, and P2P message layer.
+
+Near-term work includes finishing the SwiftSync-related spec updates,
+strengthening bridge-node reliability and performance, and keeping
+implementations like `utreexod` and [Floresta](/projects/floresta) aligned on
+the protocol.

-## Why fund it?
-
-Running your own node works best when the hardware requirements stay within
-reach. The storage and disk I/O cost of the full UTXO set pushes many users
-toward hosted infrastructure or lighter clients. Utreexo cuts that cost and
-opens the door to compact-state nodes on phones, single-board computers, and
-other constrained devices while preserving full verification.
-

-implementation work.

+
+`utreexod` is the Go daemon implementation of Utreexo, the compact-state
+approach that replaces the full UTXO set with a small accumulator plus proofs.
+It runs as a fully validating Bitcoin node and can also run as a bridge node
+that keeps the full forest and serves proofs to peers.
+
+Bridge nodes matter because Bitcoin blocks and transactions are still relayed
+without Utreexo proofs. A compact-state client needs someone to generate those
+proofs and attach them to the data it receives. `utreexod` fills that role
+today, while projects like [Floresta](/projects/floresta) build other clients
+around the same protocol work.
+
+The main tradeoff is bandwidth. `utreexod` uses much less disk I/O and memory
+than a traditional node, but it downloads extra proof data. It can also start
+from a hardcoded UTXO state, which avoids the usual initial block download path
+and brings a validating node online much faster.
+
+## Why fund it?
+
+Running your own node gets harder as the chain grows and the UTXO set gets more
+expensive to store. `utreexod` takes a different path: keep full validation,
+shrink local state, and move proof generation to bridge nodes. That makes
+compact-state verification practical on cheaper hardware and opens the door to
+more validating clients.
+
+OpenSats first funded Utreexo in the
+[fifth wave of Bitcoin grants](/blog/bitcoin-grants-july-2024#utreexo),
+supporting work on `utreexod`, bridge-node implementation, transaction
+messaging, and the BIPs needed to make multiple implementations interoperate.
+
+## What's next?
+
+Recent work landed in [`utreexod` v0.5.0][v0-5-0] and [v0.5.1][v0-5-1].
+v0.5.0 added SwiftSync-based proofless IBD and cut worst-case extra sync
+bandwidth from about 1.4 TB to about 200 GB. It also pushed more of the
+protocol onto dedicated Utreexo messages and continued bridge-node and indexer
+work. v0.5.1 followed with a netsync fix.
+
+Current work includes bridge-node performance, faster proof generation for
+historical blocks, and the review process for [BIP 181, 182, and 183][bips-pr],
+which define the accumulator, validation rules, and P2P message layer that
+other implementations need.
