The Digital Objects Network — Sepolia testnet 🟢
The Digital Objects Network is a decentralized network that facilitates the creation, execution, and exchange of Digital Objects.
Network status
This is a testnet deployment, anchored to the Ethereum Sepolia testnet. Objects, proofs, and state here are for testing only and may be reset.
| Parameter | Value |
|---|---|
| Network | Sepolia (Ethereum testnet) |
| Start slot | 10499411 — the beacon slot the network began ingesting blobs from |
| Blob address | 0x4343434343434343434343434343434343434343 — the address blob transactions are posted to |
Join the network
One line installs the driver daemon (dobjd), the dobj CLI, and the
dobj-mcp-proxy bridge into ~/.dobj/bin/:
curl -fsSL https://raw.githubusercontent.com/dobjlabs/digital-objects-network/main/install.sh | shThen start the daemon and add craft-basics with a
single dobj install. Full walkthrough — Windows, agent-driven setup, manual

Public infrastructure
Fresh installs come pre-pointed at these hosted services, so the network works out of the box:
| Service | Endpoint | Role |
|---|---|---|
| Synchronizer | synchronizer.don.pateldhvani.com | Rebuilds canonical network state from Ethereum blobs; answers live / consumed queries |
| Relayer | relayer.don.pateldhvani.com | Submits proof payloads to Ethereum as EIP-4844 blob transactions |
| Archiver | archiver.don.pateldhvani.com | Stores historical blobs durably so synchronizers can bootstrap beyond Ethereum's retention window |
Your driver is free to point elsewhere — set the endpoints with the dobj
CLI; it applies immediately, no restart:
dobj settings set \
--synchronizer https://synchronizer.don.pateldhvani.com \
--relayer https://relayer.don.pateldhvani.comCheck the current values with dobj settings get. The driver only talks to a
synchronizer and a relayer; the archiver is consumed by synchronizers (to fetch
historical blobs), so it isn't configured here.
Applications
Objects and the proof-backed actions that govern them ship as plugins
(.pexe archives). Two examples are available today:
- ⛏️ craft-basics — a survival-crafting starter: find logs, refine wood, craft picks, mine stone.
- 🚀 craft-rocket — a 53-class factory tech tree across five tiers, culminating in a provable rocket.
