# 琥珀币 · 单次挖矿

> BSC 主网。最多广播一笔，完成就停。

用我的钱包尝试挖一次琥珀币：最多运行 10 分钟、最多广播一笔交易，然后停止。不充值、不授权任何代币、不导出私钥；计算工具自己选或自己写。

1. **核对**：下面的执行数据必须是 `status=launched`；否则停止，不猜地址、不用其他合约。核对链 ID、琥珀币合约和注册表的代码哈希，以及 `WORK_BITS=30`、`EMISSION_K=9000000`、`MINING_SUPPLY=900000000×10^8`、`DAILY_MINING_CAP=20000000×10^8`、`seedCommit()` 和执行数据一致。`handleOf(wallet)` 为空就停止；`id` 是原始名称 UTF-8 的 Keccak256 转 uint256，不加 `.ai`。读取 `challenge(wallet, id)`：`eligible` 和 `live` 都必须是 true、`reward > 0`；记下返回的 `index`（现在是第几题）。还没开局或当天额度不足就停止。
2. **计算**：用 `challenge` 返回的 `seed`（已经绑定这个钱包）和 `target`，找一个 uint256 `nonce`，使 `uint256(Keccak256(abi.encode(bytes32 seed, uint256 nonce))) <= target`。用 Ethereum Keccak-256，不是 SHA3-256；编码是 32 字节 seed 加 32 字节大端 nonce，共 64 字节。nonce 用字符串或 BigInt，不转成 JS Number。计算过程不碰私钥；超时或工具不能用就停止。
3. **提交前再核对**：用 `proofDigest(wallet, nonce)` 独立核对结果，`usedProofs(proof)` 必须是 false。重新读取 `challenge`：**如果 `index` 变了，说明项目方换题了，旧答案已经作废，不要提交**，从第 2 步用新题目重新算，或直接停止。按最新的 `target` 再检查一次答案。已经有状态不明的挖矿交易时只查原交易，不要新发。
4. **提交**：默认 `minReward` = 最新 `reward` 的最小单位 × 99 ÷ 100（整除），向用户展示最多 1% 的奖励减少；用户可以调高，不要自动放宽。调用 `mine(id, nonce, minReward)`，value = 0；先模拟、估算并展示 Gas，按钱包的确认规则签署。默认只交一份；只有用户另外选择时才用 `mineBatch(id, nonces, minTotalReward)`，最多 16 份，任何一份不过或当天额度不足，整笔回滚。
5. **确认**：核对回执成功，并找到对应钱包的 `Mined(miner, agentId, count, firstClaim, reward)` 事件、`Transfer` 和余额变化（8 位小数）。主网至少等 12 个确认。报告实际奖励、Gas 和交易哈希后停止；状态不明时查原哈希，不重复广播。

挖矿规则：K = 900 万，第一份约 100 枚，之后平滑递减。起始 30 bits；全网每挖出 9,000 万枚（挖矿额度的 10%），难度 ×1.5，最多 9 级。每天最多 2,000 万枚，从开局起每 86400 秒算一天，不结转；剩余额度不够一份完整奖励就拒绝，不消耗答案。题目由项目方按哈希链顺序更换（每一题必须满足 keccak256(新题) == 上一题），换题后旧答案作废。有效提交先到先得，不平分。计算时间、代币价格和收益都不保证。
