DigiByte Core v9.26.1-pre - DigiDollar Mainnet Oracle Rehearsal
Pre-release
DigiByte Core v9.26.1-pre Release Notes
v9.26.1-pre is a one-time DigiDollar mainnet-oracle rehearsal build.
It is not a normal user release. It is not the final DigiDollar mainnet launch. It is a temporary, isolated test build for assigned oracle operators and release coordinators to prove the final mainnet oracle configuration, compressed mainnet activation path, MuSig2 oracle bundle activation, and DigiDollar wallet/RPC behavior before the real mainnet release.
Think of this build as halfway between mainnet and testnet:
- it keeps mainnet identity where oracle keys need it: mainnet genesis, mainnet message magic, mainnet address formats, and the final mainnet oracle keys;
- it isolates itself from public DigiByte mainnet by using PRE-only ports, no seed discovery, no fixed seeds, and a separate data directory;
- it compresses historical DigiByte fork points and DigiDollar activation timing so the full activation path can be tested quickly from a fresh chain.
Development branch: feature/digidollar-v1
Release tag: v9.26.1-pre (PRE/oracle rehearsal only)
Required PRE Configuration
Run this build with a fresh PRE data directory. Put digibyte.conf in that fresh data directory, not in an existing normal mainnet ~/.digibyte directory. The node will still report chain=main, but this build stores its chain data under the mainnet-pre network subdirectory.
Example operator digibyte.conf:
# DigiByte Core v9.26.1-pre isolated mainnet-oracle rehearsal
# Use this only with a fresh PRE data directory. Do not use normal ~/.digibyte.
server=1
listen=1
txindex=1
digidollar=1
# Mainnet-PRE network ports
port=12046
rpcport=14046
# Join the coordinated PRE network through the bootstrap node.
addnode=digibyte.io:12046
# Keep this PRE build isolated from public DigiByte mainnet peer discovery.
dnsseed=0
fixedseeds=0
discover=0
listenonion=0
onion=0
upnp=0
natpmp=0
# Keep RPC local unless you have a separate trusted tunnel/firewall.
rpcbind=127.0.0.1
rpcallowip=127.0.0.1Network/firewall requirements:
- Open inbound TCP
12046for the PRE P2P network if this node should accept peer/oracle connections. - Do not open or use public mainnet P2P port
12024for this rehearsal. - Do not expose RPC port
14046to the public internet. - Use
addnode=digibyte.io:12046; the PRE bootstrap/oracle node must also listen on TCP12046.
Read This First
Do not run v9.26.1-pre as a normal wallet release.
This build is for a controlled oracle rehearsal. It intentionally changes mainnet startup behavior in order to create a side-mainnet test chain that uses real mainnet oracle keys but does not join public DigiByte mainnet.
Normal users should not install this build for everyday funds, merchant use, mining, exchange use, or public mainnet operation.
Oracle operators should only run it with the coordinated PRE instructions and a fresh PRE data directory. Do not point it at an existing ~/.digibyte mainnet directory.
After this PRE rehearsal is complete, the PRE isolation/fast-activation commit is expected to be reverted before preparing the final mainnet launch build.
Purpose
The goal of v9.26.1-pre is to test the final mainnet DigiDollar oracle setup under mainnet-like conditions without touching public mainnet.
This lets us verify:
- the final 35-slot mainnet oracle roster;
- 7-of-35 MuSig2 oracle quorum configuration;
- DigiDollar, oracle, and MuSig2 activation at the same height;
- mainnet address/key handling for oracle wallets;
- BIP9 activation flow with real mined blocks;
- DigiDollar wallet and RPC behavior after activation;
- peer isolation from public mainnet.
The build exists because public testnet does not perfectly reproduce mainnet conditions. This PRE chain keeps the important mainnet identity pieces while using testnet-style fast activation timing.
Mainnet-PRE Network Details
| Item | v9.26.1-pre value |
|---|---|
| Chain type | Main (chain=main) |
| Data directory suffix | mainnet-pre |
| Mainnet genesis | unchanged: 0x7497ea1b465eb39f1c8f507bc877078fe016d6fcb6dfad3a64c98dcc6e1e8496 |
| Mainnet message magic | unchanged: fa c3 b6 da |
| Address format | unchanged mainnet DigiByte addresses |
| Default PRE P2P port | 12046 |
| Default PRE RPC port | 14046 |
| Default PRE onion target port | 14146 |
| Public mainnet P2P port | not used; public 12024 peers are blocked for this PRE build |
| DNS seeds | disabled |
| Fixed seeds | disabled |
| Checkpoints | genesis-only for PRE chain replay |
| AssumeUTXO / assumevalid | disabled for PRE rehearsal |
| DigiDollar BIP9 bit | 23 |
| BIP9 window | 100 blocks |
| BIP9 threshold | 70 blocks |
| DigiDollar minimum activation height | 600 |
| Oracle activation height | 600 |
| MuSig2 format activation height | 600 |
| Oracle roster | 35 active slots |
| Oracle quorum | 7 signatures from the configured 35-key MuSig2 roster |
The PRE build deliberately keeps the mainnet genesis and magic bytes so oracle operators test the same mainnet key context. Isolation comes from the PRE data directory, PRE ports, disabled peer discovery, and the public-mainnet-port guard.
Fast Activation Logic
The PRE chain compresses historical DigiByte rule changes so a fresh chain reaches the modern DigiDollar test surface quickly.
Compressed PRE fork schedule:
| Rule point | PRE height |
|---|---|
| BIP34 | 1 |
| BIP65 | 1 |
| BIP66 | 1 |
| CSV | 1 |
| SegWit | 0 |
| DigiShield boundary | 67 |
| MultiAlgo | 100 |
| Always-update difficulty | 200 |
| Work computation update | 400 |
| ReserveAlgoBits | 450 |
| Algo swap | 490 |
| Odocrypt | 500 |
| DigiDollar / oracle / MuSig2 | 600 |
DigiDollar uses BIP9 bit 23 with a 100-block window and 70-block threshold. The expected PRE flow is:
| Height range | Expected deployment state |
|---|---|
| early chain through first signalling window | started once the window opens |
| after a successful 70-of-100 signalling window | locked_in |
| after the height-599 tip / block-600 gate | active |
height 600+ |
DigiDollar, oracle runtime, and MuSig2 bundle format are all enabled together |
This is intentionally fast. It is designed to prove activation behavior, not to reproduce years of mainnet elapsed time.
What Changed From RC46
- Mainnet is temporarily configured as
mainnet-prefor this rehearsal. - Mainnet genesis, message magic, address formats, and oracle keys stay mainnet.
- PRE P2P/RPC ports are
12046/14046. - DNS seeds and fixed seeds are disabled so the node does not discover public mainnet peers.
- Public mainnet P2P port
12024is guarded against accidental outbound use. - Historical DigiByte fork heights are compressed so a fresh chain can reach the current rule set before DigiDollar activation.
- DigiDollar BIP9 uses a 100-block window, 70-block threshold, and minimum activation height
600. - DigiDollar, oracle runtime, and MuSig2 oracle bundle format all activate together at height
600. - The final 35-slot mainnet oracle roster is configured on PRE port
12046.
What Did Not Change
- The real mainnet genesis hash did not change.
- The real mainnet message magic did not change.
- Mainnet address prefixes did not change.
- The DigiDollar economic rules are not redesigned in this PRE build.
- Oracle quorum remains 7-of-35.
- Testnet26 remains its own network and is not reset by this PRE release.
- Regtest activation behavior is not changed by this PRE release.
- This PRE release does not activate DigiDollar on public mainnet.
Final Mainnet-PRE Oracle Roster
All oracle endpoints use PRE port 12046 for this rehearsal. Public mainnet oracle operation will use the final launch instructions after PRE is reverted and the formal mainnet build is prepared.

Operator Guidance
This release is only for assigned oracle operators and coordinated PRE testers.
Minimum rules:
- Use a fresh PRE data directory.
- Do not reuse normal mainnet
~/.digibytedata. - Do not copy normal mainnet
peers.dat. - Do not add or connect to public mainnet peers on port
12024. - Open/use PRE P2P port
12046. - Confirm
getblockchaininforeportschain=mainwhile the data directory path ismainnet-pre. - Confirm
getdigidollardeploymentinforeports:min_activation_height = 600oracle_activation_height = 600musig2_format_activation_height = 600oracle_pubkey_count = 35oracle_consensus_required = 7oracle_total_slots = 35
- Start oracle runtime only after the PRE chain reaches DigiDollar/oracle activation.
This PRE chain is allowed to use mainnet oracle keys because it stays isolated from public mainnet.
Validation Status
Known local validation for the PRE code line:
| Gate | Status |
|---|---|
| Mainnet-PRE chainparams unit coverage | PASS: verifies mainnet genesis/magic, PRE ports/datadir, disabled seeds, compressed fork heights, 100/70 BIP9 window, DigiDollar/oracle/MuSig2 at 600, and 35-slot oracle roster on port 12046 |
| Full unit suite | PASS: ./src/test/test_digibyte --log_level=error ran 3407 test cases with no errors after v9.26.1-pre staging |
| Full functional suite | PASS on local PRE branch before release-note drafting |
| Fuzz target smoke run | PASS on local PRE branch before release-note drafting |
| Five-node Qt PRE rehearsal | PASS: five Qt nodes running from isolated temp datadirs, synced together, with localhost-only peers |
| CPU mining rehearsal | PASS: separate CPU miners proved sha256d, scrypt, Groestl/Myriad-Groestl, skein, and qubit block production before the Odocrypt gate; post-Odo mining continued to activation |
| DigiDollar BIP9 live state | PASS: observed started, locked_in, and active; live PRE chain reached height 605 with enabled=true, status=active, 35 oracle slots, and 7-signature quorum |
| DigiSwarm oracle wallet | PASS/PENDING: wallet loaded, configured, and authorized for slot 15 with the expected mainnet key; runtime start is pending wallet unlock with walletpassphrase |
Before publishing binaries, rerun and record:
make -j$(nproc)
./src/test/test_digibyte --show_progress
test/functional/test_runner.py --jobs=8
./src/test/fuzz/test_runner.py <fuzz-bin-dir> -l DEBUG <target-list>
./test_oracle_mainnet.shRevert Plan
The PRE changes should stay isolated in an easy-to-revert commit or small commit stack.
After the oracle rehearsal is complete:
- Save the PRE activation/oracle test results.
- Shut down PRE nodes.
- Preserve logs and oracle validation artifacts.
- Revert the PRE isolation/fast-activation commit.
- Prepare the final mainnet launch build with normal mainnet ports, normal mainnet peer discovery, and the chosen final activation parameters.
Do not ship this PRE configuration as the final public mainnet release.
