Run a testnet node
The reset testnet started on 2026-09-26 00:00 UTC from a new genesis block. It runs Neurai node
2.0.0 (protocol 70030) from the DePIN-Test branch;
older releases cannot connect to it.

Step 1
Build from source
Follow doc/build-unix.md for the
dependencies; the only new one is liboqs for the post-quantum signatures.
git clone --branch DePIN-Test https://github.com/NeuraiProject/Neurai.git
cd Neurai
./autogen.sh
./configure # liboqs 0.16.0 is required; the depends/ system can build it
make -j"$(nproc)"Step 2
Configure
Every option also works on the command line with a leading dash, for example -testnet.
# ~/.neurai/neurai.conf (testnet data goes to ~/.neurai/testnet/)
testnet=1
server=1
# Indexes used by explorers, wallets and the privacy pools
txindex=1
addressindex=1
spentindex=1
# Family of new wallet addresses: legacy, ecdsa or pq
addresstype=ecdsa
rpcuser=change-me
rpcpassword=change-me-tooStep 3
Start and check the chain
The node finds peers through the DNS seeds. Confirm the genesis before trusting what it reports.
./src/neuraid -daemon
./src/neurai-cli -testnet getblockchaininfo
./src/neurai-cli -testnet getblockhash 0 # must print the genesis below
./src/neurai-cli -testnet getpeerinfoOptional
Mine some blocks
Testnet uses SHA256d, not KAWPOW, and its difficulty is low, so the node's built-in miner can find blocks on an ordinary CPU. Each block pays 25,000 XNA.
ADDR=$(./src/neurai-cli -testnet getnewaddress "" legacy)
./src/neurai-cli -testnet generatetoaddress 1 "$ADDR"

Schedule
Activation heights
Blocks 1–9 ran the rules from before the new proposals; block 10 switched almost everything on at once. Mainnet has none of these scheduled yet.
| Feature | Height | Notes |
|---|---|---|
| Assets, messaging, restricted assets | Genesis |
Active from the first block as a plain rule. |
| NIP-028 block time reduction | 10 |
30-second blocks, halved subsidy, 120-block reorg cap. |
| AuthScript v1 and the covenant opcodes | 10 |
Introspection, CTV, CAT/SPLIT, hashes, 64-bit arithmetic, tx v3 reference inputs. |
| Strict PQ (v2) and strict ECDSA (v3) addresses | 10 |
tpq1z… and tnq1r… address families, NIP-041. |
| CSFS, Ed25519, CHECKSIGADD | 10 |
Signature opcodes. |
| TXHASH, script trees, execution budgets | 10 |
NIP-042, NIP-043, NIP-044, NIP-046. |
| OP_ZKVERIFY and the ZK public tree | 10 |
Privacy pool profiles 1 and 2 (C4, C5). |
| NIP-040 asset marker | 10 |
Outputs use the xna marker; rvn before block 10. |
| DePIN transfer state | 10 |
Open, close and seal for DePIN tokens. |
| ZK portable tree | 100 |
Privacy pool profile 3 (C6). |
