[ANN] Orange (OAG) | RandomX CPU-only | No premine | Solo mining | Rust

About the coin (primary summary)

• What coin: Orange (OAG)
• Mining algorithm: RandomX
• CPU-only or not: CPU-only
• Brief description: Orange is a small UTXO coin running on the RandomX algorithm and written in Rust. The project is a hobby of a Japanese university student, the main network launched in September 2026, blocks are generated every 60 seconds, the block reward is fixed at 10 OAG with no halving, maximum emission is 1 000 000 000 OAG, there is no premine, and mining is possible only solo, built into the full node.
• Where to mine/pool: Mining is only possible solo; there are no pools, the miner is built into the node.
• Wallet/links: The wallet is created when the node is started (requires a password of at least 8 characters); Discord is not yet available, discussion takes place in this thread or via GitHub issues; there is no information about exchanges or external links.
• Community reaction: User lightbit asked for a Discord link, to which the author replied that it does not exist yet and suggested staying in the thread or opening an issue on GitHub. Another user drywall777 asked for help with the explorer command, but no solution was provided in the given replies.

Main topic of new posts:

Discussion of technical details of launching and using the Orange (OAG) node – mining setup, explorer, solving port and synchronization issues, as well as announcements of new client versions and project development plans.

Key news/updates:

• Release v0.1.1: fast mode now uses a single shared RandomX dataset for all threads, added support for huge pages.
• Release v0.1.3: wallet operates on a pruned node, the Sign tab allows selecting an address for signing, explorer tables are adapted for mobile screens.
• Release v0.1.7: explorer shows who found the last 100 blocks and their hash‑rate share; reorganisation messages improved (each discarded and accepted block is logged); LWMA window (N = 90) documented for difficulty adjustment.
• Release v0.2.0: fixed an initial synchronization bug that could stop due to missed blocks when restarting the node; repeated messages about switching the RandomX seed remain, but do not halt synchronization and will be fixed later.
• Instructions for using the explorer: it is built into the node, started with the --explorer flag (or with a port --explorer 127.0.0.1:8081), listens only on localhost.
• Guide for building on Apple Silicon via brew install cmake, Rust toolchain and cargo build --release.
• Call for node operators to open port 9444 and add --external-addr <IP>:9444 to improve network connectivity.
• Mention of open source code (MIT) and invitation to create a GUI wallet, installers, improve documentation without an official team or fundraising.

Problems/complaints:

• Port 8080 conflict when starting the explorer (error Only one usage of each socket address), resolved by stopping the second node or changing the explorer port.
• Running multiple nodes on one PC leads to a “one instance” error due to competition for the P2P port 9444 and the chain database.
• Claims that PoW is not RandomX (low hash rate); developer confirmed use of the randomx-rs library and explained low speed due to lack of huge pages and fast mode without --fast.
• Repeated logs switched the RandomX seed around height ≈14400, slowing initial sync (fix planned for a future release).
• Difficulties with initial wallet and explorer setup for new users (need to create a wallet via http://127.0.0.1:25565/ and correctly specify

Main topic of new posts: Release of Orange node version 0.3.0 and XMRig fork allowing mining OAG with external miners.

Key news/updates:

• oag-node v0.3.0: added --stratum parameter for working with external miners (default 127.0.0.1:1919); --pool option launches a native PPLNS pool (0 % fee, minimum payout 1 OAG, payouts every 10 minutes, status page on port 8000).
• Node 0.3.0 is backward compatible with 0.2.x nodes without consensus changes.
• XMRig for OAG (v6.26.0-oag.1): fork adds the rx/oag algorithm; static builds available for Windows x64 and Linux x64/arm64.
• Launch instruction:

oag-node run --network mainnet --stratum

then

xmrig -o 127.0.0.1:1919 -u <your OAG address> -a rx/oag

• XMRig donation remains the standard 1 % (≈1 minute of 100 spent on mining Monero for XMRig authors); source code is open (GPL‑3.0), SHA256SUMS is attached to the release.

Problems/complaints:

• Mentioned that Windows Defender may flag xmrig.exe as a trojan (Wacatac.B!ml) – a false positive common to most XMRig builds.

Overall tone: positive/neutral – announcement of new mining and pool capabilities, call for self‑hosting, without critical remarks.

Main topic of new posts:

Release of Orange v0.4.0 with a soft fork at block 40 000, introducing enforcement of relative locktime (BIP68), and a daily report for 17 days of network operation with current hash‑rate figures, pool growth, and coin distribution statistics.

Key news/updates:

• Release v0.4.0 (GitHub tag v0.4.0) – soft fork activating relative locktime from block 40 000 (around 15 Oct).
• The rule applies only to version 2 transactions; version 1 remain untouched.
• Update mandatory for miners and pool operators before height 40 000; old nodes will reject blocks violating the new rule.
• Upgrade instruction: stop the node, replace the oag-node and oag-wallet binaries, start again – data is preserved, resync not required.
• Daily report for 17 days: height 23 743, average block time 61 s, hash‑rate grew from ~2 kH/s (day 10) to ~154 kH/s (hour) and ~139 kH/s (24 h).
• Two pools appeared (one official, the other launched by a user via oag-node --pool).
• Mining concentration: the largest miner mined ~47 % of the last 100 blocks (61 % on Oct 3); warning that >50 % hash‑rate could allow recent blocks to be orphaned.
• Addresses with coins: 39 (was 21); addresses that mined a block: 30 (was 14); reward‑less transactions: 407 (was 34); emission: 237 430 OAG.
• The largest address holds 31.7 % of the coins and belongs to user drywall777.

Problems/complaints:

• Warning about high hash‑rate concentration: one miner controls close to 50 % of recent blocks, potentially allowing recent transactions to be reversed if its share grows further.
• The emergence of a second pool changes the original “solo‑only mining” stance, which may raise questions for those who expected a strictly solo‑only mode.

Overall tone:

Positive/neutral – the network is steadily growing, hash‑rate increasing, infrastructure (pools) appearing, but a mining centralisation risk is noted, requiring community attention.

Main topic of new posts:

New versions of the Orange (OAG) node – v0.4.1 and v0.4.3 – released with fixes for network and reorganization issues.

Key news/updates:

• v0.4.1:
• Fixed a bug where the node kept dialing itself (“detected a connection to ourselves”), even when --external-addr was set; now the node’s own address is removed from the address book.
• Added a second primary seed node: oagnode.vslabs.co.in.
• Update not required for 0.4.0 nodes; users of 0.3.x and older should upgrade before block ≈ 40 000 (around 15‑16 Oct 2026 UTC).
• v0.4.3:
• Fixed a chain reorganization issue where a transaction spent an output created in the same block; the node now correctly rolls back such blocks.
• This is not a hard fork; old and new nodes remain compatible, no database migration required.
• Added regression tests for both in‑memory and on‑disk (redb) storage.
• Recommended to update all node operators, especially seed nodes and miners.

Problems/complaints:

No new user-reported problems or complaints were mentioned in the recent posts.

Overall tone:

Positive/neutral – focus on fixes and improving network stability.
