SCDO is a proof-of-work chain. Miners bundle transactions into blocks and make the chain's history expensive to rewrite; independent nodes check every block and serve the network. Both keep SCDO open and verifiable.

SCDO 是工作量证明（PoW）链。矿工把交易打包成区块，使链上历史难以被篡改；独立节点校验每一个区块并为网络提供服务。二者共同保证 SCDO 的开放与可验证。

Mine SCDO Shard0 (EVM) with a GPU用 GPU 挖 SCDO Shard0 (EVM)

Algorithm Ethash (same as pre-merge Ethereum, 30,000-block epochs, not etchash) · chain ID / network ID 5680 · P2P port 30368 · block target ~13 s · epoch-0 DAG ≈1 GB. You mine through your own node, so block rewards go to the address you choose.

算法 Ethash（与合并前的以太坊相同，每 30,000 块一个纪元，不是 etchash）· Chain ID / Network ID 5680 · P2P 端口 30368 · 目标出块约 13 秒 · 纪元 0 的 DAG 约 1 GB。通过你自己的节点挖矿，出块奖励进入你指定的地址。

  1. Easiest – Windows + NVIDIA GPU (RTX 20/30/40/50 series): download scdo-shard0-gpu-miner-v1.0.3-windows-amd64.zip, unzip to e.g. C:\scdo-miner, add that folder as a Windows Defender exclusion (every GPU miner is flagged as a “potentially unwanted app”), open start-mining.bat in Notepad, set set WALLET=0x… to your address and double-click it. It starts a local core-geth node (rewards to your address) and a small stratum proxy, downloads the NVIDIA miner Rigel 1.23.2 from its official release (SHA256-checked; closed source, 0.7% dev fee) and starts mining once the node has synced. If SmartScreen says “Windows protected your PC”, click More info then Run anyway (the files are not code-signed). To stop, run stop-mining.bat – it shuts the node down gracefully; do not close the “SCDO node” window with X. Linux: scdo-shard0-gpu-miner-v1.0.3-linux-amd64.tar.gz, WALLET=0x… ./start-mining.sh. Since v1.0.3 the package also registers your node for node rewards (distributed by online time) with your WALLET as reward address; set PAYOUT=0x… for another address or PAYOUT=off to opt out.
  2. Manual / other miners: initialise once with ./core-geth-scdo-linux-amd64 --datadir ./scdo0 init scdo-shard0-genesis.json, run the node without --mine:
    ./core-geth-scdo-linux-amd64 --datadir ./scdo0 --networkid 5680 --port 30368 --syncmode full --bootnodes enode://1d2c370db7c419349e2313f20023f6b379f946990042b9b42df45cb56e4c3487df0d36c52cd81308fcdf312450f758a6213fcac21213e94a71af4a3c9392601f@82.223.19.88:30368 --http --http.addr 127.0.0.1 --http.port 8545 --http.api eth,net,web3,miner --miner.etherbase 0xYOUR_ADDRESS
    then the proxy from the package, which starts getwork mining only after the node has synced:
    ./scdo-stratum -rpc http://127.0.0.1:8545 -listen 127.0.0.1:3333 -autostart -ref-rpc https://scdoscan.io/rpc/0
    and point any Ethash stratum miner at 127.0.0.1:3333, e.g. rigel -a ethash -o ethproxy+tcp://127.0.0.1:3333 -u 0xYOUR_ADDRESS or lolMiner --algo ETHASH --pool 127.0.0.1:3333 --user 0xYOUR_ADDRESS --ethstratum ETHPROXY.
  3. Do not mine before your node has synced: a fresh node would otherwise build its own chain from the genesis block. getwork miners such as ethminer can still use http://127.0.0.1:8545, but ethminer’s last release (2019) predates RTX 40/50 cards.
  1. 最简单：Windows + NVIDIA 显卡（RTX 20/30/40/50 系列）：下载 scdo-shard0-gpu-miner-v1.0.3-windows-amd64.zip，解压到例如 C:\scdo-miner，在 Windows Defender 中把该文件夹加入排除项（所有 GPU 挖矿软件都会被标记为“可能不需要的应用”），用记事本打开 start-mining.bat，把 set WALLET=0x… 改成你的地址，然后双击运行。它会启动本地 core-geth 节点（奖励进入你的地址）和一个小型 Stratum 代理，从官方发布页下载 NVIDIA 挖矿软件 Rigel 1.23.2（校验 SHA256；闭源，开发者费 0.7%），节点同步完成后自动开始挖矿。如果出现“Windows 已保护你的电脑”（SmartScreen），请点更多信息，再点仍要运行（文件没有代码签名）。停止时请运行 stop-mining.bat（会正常关闭节点），不要用 X 关闭“SCDO node”窗口。Linux：scdo-shard0-gpu-miner-v1.0.3-linux-amd64.tar.gz，运行 WALLET=0x… ./start-mining.sh。从 v1.0.3 起，挖矿包会以你的 WALLET 作为奖励地址自动登记节点奖励（按在线时长发放）；如需其他地址请设置 PAYOUT=0x…，不登记请设置 PAYOUT=off。
  2. 手动 / 其他挖矿软件：首次初始化 ./core-geth-scdo-linux-amd64 --datadir ./scdo0 init scdo-shard0-genesis.json，运行节点（不要加 --mine）：
    ./core-geth-scdo-linux-amd64 --datadir ./scdo0 --networkid 5680 --port 30368 --syncmode full --bootnodes enode://1d2c370db7c419349e2313f20023f6b379f946990042b9b42df45cb56e4c3487df0d36c52cd81308fcdf312450f758a6213fcac21213e94a71af4a3c9392601f@82.223.19.88:30368 --http --http.addr 127.0.0.1 --http.port 8545 --http.api eth,net,web3,miner --miner.etherbase 0xYOUR_ADDRESS
    再运行安装包里的代理（节点同步完成后才开始 getwork 挖矿）：
    ./scdo-stratum -rpc http://127.0.0.1:8545 -listen 127.0.0.1:3333 -autostart -ref-rpc https://scdoscan.io/rpc/0
    然后把任意 Ethash Stratum 挖矿软件指向 127.0.0.1:3333，例如 rigel -a ethash -o ethproxy+tcp://127.0.0.1:3333 -u 0xYOUR_ADDRESS 或 lolMiner --algo ETHASH --pool 127.0.0.1:3333 --user 0xYOUR_ADDRESS --ethstratum ETHPROXY。
  3. 节点同步完成前不要挖矿，否则新节点会从创世块开始自建一条链。ethminer 等 getwork 挖矿软件仍可直接连接 http://127.0.0.1:8545，但 ethminer 最后一次发布是 2019 年，早于 RTX 40/50 系列显卡。

Each block pays the miner the standard Ethash block reward (2 SCDO) plus fees. Block rewards are distributed automatically by the chain’s public, verifiable protocol rules; every reward is visible on this explorer.

每个区块按标准 Ethash 规则向矿工发放区块奖励（2 SCDO）及手续费。区块奖励由链上公开、可核验的协议规则自动发放，每一笔都可以在本浏览器上查到。

Mine with the project pool (PPLNS)使用项目方矿池挖矿（PPLNS）

The SCDO project runs a public mining pool. It is operated by the project (the same company that mines to the reserve address), and everything about it is public: pool page with every miner’s hashrate, shares, block rewards and pool payouts (pending / paid), all blocks and all payout transactions.

SCDO 项目方运营一个公开矿池。矿池由项目方（即向储备地址挖矿的同一家公司）运营，所有信息公开：矿池页面显示每位矿工的算力、份额、出块奖励和矿池结算（待支付 / 已支付），以及全部区块和全部付款交易。

large大矿工: ≥ 500 MH/s1%
medium中矿工: 100 – 500 MH/s3%
small小矿工: < 100 MH/s5%

Stratum / 代理 · Proxy
The protocol miners use to get work and send shares; scdo-stratum turns it into getwork calls to your own node.矿机获取任务、提交份额所用的协议；scdo-stratum 把它转换成对你自己节点的 getwork 调用。
份额 / Share
A solution your miner sends to the pool that proves work at the pool's (easier) difficulty; shares measure your contribution.矿机按矿池设定的较低难度提交的计算结果，用来证明并计量你贡献的工作量。
PPLNS
"Pay per last N shares": each block the pool finds is shared among the miners of the most recent shares, in proportion to their work.“按最近 N 个份额分配”：矿池每挖到一个区块，按最近一段份额中各矿工的工作量比例分配。
手续费档位 / Fee tier
The pool fee rate (1%, 3% or 5%) chosen from your 24-hour average hashrate; larger miners pay a lower rate.按你 24 小时平均算力确定的矿池费率（1%、3% 或 5%），算力越大费率越低。
最低支付 / Min payout
The smallest balance that is sent on-chain; smaller amounts wait until they reach it.链上付款的最低金额；未达到的余额会累积到达标后再付。

A found block that did not make it into the chain and was not included as an uncle; it gets no reward.未进入规范链、也未被收录为叔块的区块，没有奖励。
储备地址 / Reserve
The company's own address (project-operated mining, also the faucet); pool fees go here and it funds the node reward distribution wallet.公司自己的地址（项目方自挖，也是水龙头）；矿池费用进入该地址，并由它为节点奖励发放钱包注资。
节点奖励 / Node rewards
SCDO distributed automatically to public, synced nodes that serve the network, split by measured online time under the published rules.按公开规则、根据实测在线时长，自动发放给为网络提供服务的公开、已同步节点的 SCDO。
奖励地址登记 / --identity
Starting a node with --identity scdo-node:0xYOUR_ADDRESS tells the bootnode which public address receives the node rewards.启动节点时加上 --identity scdo-node:0x你的地址，就是告诉种子节点节点奖励发放到哪个公开地址。
分片 / Shard
