From e366ceb336550a72c76efea4c98a2a08cca27bce Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 19 May 2026 14:25:18 +0530 Subject: feat(mining): Bitcoin mining-for-bandwidth payment system New modules: - mining_payment.c/h: hashprice calc (nbits->difficulty->sat/GH/s/day), share validation, client stats, allotment conversion (ms + bytes) - stratum_client.c/h: SV1 upstream pool connection (subscribe/authorize/submit) - stratum_proxy.c/h: Local SV1 TCP server for downstream miners, job broadcast - sw_miner.c/h: Software SHA256d miner (ESP32 CPU fallback) - asic_miner.c/h: ASIC detection stub (BM1366/BM1368 SPI) Config: - config.h/c: mining_payout_mode_t enum (auto/pool/upstream/proxy_only), stratum pool settings, mining port, hashprice override, sandbox mint access - Defaults fill nostr_seed_relays (8/8) and nostr_relays (4/4) with fast relays Integration into existing modules: - session.h/c: payment_method_t enum (CASHU/MINING/BYTES) - firewall.h/c: firewall_set_mining_port(), firewall_set_sandbox_mint_access() - tollgate_api.c: GET /mining/job, POST /mining/share, GET /mining/stats - tollgate_client.h/c: TG_CLIENT_MINING state, mining discovery tag parsing - tollgate_main.c: mining init in start_services(), stratum_client_tick() in loop - captive_portal.c: tabbed Cashu/Mine UI with live hashrate polling Unit tests (69 new assertions across 4 suites): - test_mining_payment (23 tests): nbits->difficulty, hashprice, client stats, allotment - test_stratum_proxy (21 tests): job set/get, stats, type validation - test_session_payment_method (12 tests): PAYMENT_METHOD enum, bytes/cashu methods - test_tollgate_client_mining (20 tests): mining tag parsing, discovery struct - test_firewall_sandbox (16 tests): client grant/revoke, max clients, setters Enhanced test stubs: - BaseType_t/pdPASS in freertos/task.h - lwip: sockets.h, etharp.h, prot/ip.h, prot/ip4.h, prot/tcp.h, netif.h - dns_server.h, esp_wifi_ap_get_sta_list.h Build fixes: - cvm_server.c: replace esp_timer_get_time() with xTaskGetTickCount(), fix process_relay_message() 3-arg call to 2-arg, add WS keepalive ping - stratum_proxy.c: widen task_name buffer 16->20 - sw_miner.c: add missing #include esp_random.h - nucula_src: save_proofs() moved to public in wallet.hpp Nostr relay updates: - nostr_seed_relays: +relay.anzenkodo.workers.dev, +nostr.koning-degraaf.nl, +knostr.neutrine.com, +nostr.einundzwanzig.space (8/8 slots) - nostr_relays: +relay.anzenkodo.workers.dev, +nostr.koning-degraaf.nl (4/4 slots) Squash-merge of feature/mining-payment (5 commits: c75230e..9d98ba1) --- main/sw_miner.c | 112 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 112 insertions(+) create mode 100644 main/sw_miner.c (limited to 'main/sw_miner.c') diff --git a/main/sw_miner.c b/main/sw_miner.c new file mode 100644 index 0000000..cdd98a0 --- /dev/null +++ b/main/sw_miner.c @@ -0,0 +1,112 @@ +#include "sw_miner.h" +#include "stratum_proxy.h" +#include "stratum_client.h" +#include "mining_payment.h" +#include "config.h" +#include "esp_log.h" +#include "esp_random.h" +#include "mbedtls/sha256.h" +#include "freertos/FreeRTOS.h" +#include "freertos/task.h" +#include + +static const char *TAG = "sw_miner"; +static bool s_running = false; +static TaskHandle_t s_task_handle = NULL; +static double s_hashrate = 0.0; + +static void sha256d(const uint8_t *data, size_t len, uint8_t *hash) +{ + uint8_t tmp[32]; + mbedtls_sha256(data, len, tmp, 0); + mbedtls_sha256(tmp, 32, hash, 0); +} + +static void sw_miner_task(void *arg) +{ + ESP_LOGI(TAG, "Software miner started"); + + uint64_t hashes = 0; + int64_t start_time = (int64_t)xTaskGetTickCount() * portTICK_PERIOD_MS; + + uint8_t header[80]; + uint8_t hash[32]; + + while (s_running) { + const stratum_job_t *job = stratum_proxy_get_current_job(); + if (!job || !job->valid) { + vTaskDelay(pdMS_TO_TICKS(1000)); + continue; + } + + stratum_job_t local_job; + memcpy(&local_job, job, sizeof(stratum_job_t)); + + memcpy(header, local_job.prevhash, 32); + memcpy(header + 32, local_job.merkle_root, 32); + + uint32_t start_nonce = esp_random(); + uint32_t end_nonce = start_nonce + 1000; + + for (uint32_t nonce = start_nonce; nonce < end_nonce && s_running; nonce++) { + header[76] = (nonce >> 0) & 0xFF; + header[77] = (nonce >> 8) & 0xFF; + header[78] = (nonce >> 16) & 0xFF; + header[79] = (nonce >> 24) & 0xFF; + + sha256d(header, 80, hash); + hashes++; + + if (memcmp(hash, local_job.target, local_job.target_len) <= 0) { + ESP_LOGI(TAG, "Valid share found!
