Synchronization
使用奇偶校驗扭曲時，狀態數據驗證 PoW 需要多長時間？
Ethcore 聲稱
parity --warp只需一分鐘即可同步鏈。我自己試了一下，在我的機器上確實需要大約 2-3 分鐘，但連接有點不好。0 ✓ user@hoster ~ $ parity --mode passive --db-compaction ssd --pruning fast --warp --cache-size 4096 2016-11-30 12:21:26 Starting Parity/v1.4.5-beta-UNKNOWN-UNKNOWN/x86_64-linux-gnu/rustc1.13.0 2016-11-30 12:21:26 State DB configuation: fast 2016-11-30 12:21:26 Operating mode: passive 2016-11-30 12:21:26 Configured for Frontier/Homestead using Ethash engine 2016-11-30 12:21:32 Syncing snapshot 1/69 #0 4/10/25 peers 3 MiB db 7 KiB chain 0 bytes queue 10 KiB sync [...] 2016-11-30 12:23:43 Syncing snapshot 68/69 #0 1/14/25 peers 3 MiB db 7 KiB chain 0 bytes queue 10 KiB sync 2016-11-30 12:23:48 Syncing #2720000 e0a7…f90a 0 blk/s 0 tx/s 0 Mgas/s 0+ 0 Qed #2720000 8/11/25 peers 0 bytes db 656 KiB chain 0 bytes queue 12 KiB sync 2016-11-30 12:23:56 Syncing #2720149 3f85…a2c7 120 blk/s 979 tx/s 40 Mgas/s 0+ 613 Qed #2721511 8/14/25 peers 23 MiB db 2 MiB chain 5 MiB queue 1 MiB sync 2016-11-30 12:23:57 Imported #2721511 3702…acd3 (0 txs, 0.00 Mgas, 1.02 ms, 0.51 KiB) + another 3 block(s) containing 4 tx(s) 2016-11-30 12:24:11 Imported #2721512 e6c5…2d67 (0 txs, 0.00 Mgas, 0.74 ms, 0.51 KiB)但是，狀態數據經過 PoW 驗證需要多長時間？而且，它是否經過驗證？
--warp下載最近的 30k 塊并快速驗證 PoW 和總難度。這大約需要 1-5 分鐘。0 ✓ user@hoster ~ $ parity --mode active --db-compaction ssd --warp --cache-size 4096 2016-12-01 22:27:08 Starting Parity/v1.4.5-beta-UNKNOWN-UNKNOWN/x86_64-linux-gnu/rustc1.13.0 2016-12-01 22:27:08 State DB configuation: fast 2016-12-01 22:27:08 Operating mode: active 2016-12-01 22:27:08 Configured for Frontier/Homestead using Ethash engine 2016-12-01 22:27:14 Public node URL: enode://94ea88a67d176eac49e5aa64aa277aa5bd48e96bb549c1852545d943dedc4409039072766387597b415a9ccd38167ab848bfdf93919009d2d942687aa8ccb714@172.16.16.11:30303 2016-12-01 22:27:19 Syncing snapshot 0/66 #0 3/11/25 peers 3 MiB db 7 KiB chain 0 bytes queue 10 KiB sync -------------------- ^ warp started ------------------------------------------------ [...] 2016-12-01 22:30:14 Syncing snapshot 61/66 #0 3/16/25 peers 3 MiB db 7 KiB chain 0 bytes queue 10 KiB sync 2016-12-01 22:30:19 Syncing #2730000 fa0e…0b90 0 blk/s 0 tx/s 0 Mgas/s 0+ 0 Qed #2730000 2/16/25 peers 0 bytes db 8 KiB chain 0 bytes queue 11 KiB sync -------------------- ^ warp finished ----------------------------------------------- 2016-12-01 22:30:21 Imported #2730131 adda…db11 (3 txs, 0.09 Mgas, 1.59 ms, 0.99 KiB) 2016-12-01 22:30:54 #59817 14/15/25 peers 3 MiB db 23 MiB chain 0 bytes queue 6 MiB sync ------------------------- ^ normal sync started ------------------------------------ 2016-12-01 22:31:17 Imported #2730134 68eb…bd60 (0 txs, 0.00 Mgas, 7.36 ms, 1.03 KiB) + another 1 block(s) containing 16 tx(s) 2016-12-01 22:31:29 #72301 11/13/25 peers 3 MiB db 26 MiB chain 0 bytes queue 6 MiB sync 2016-12-01 22:30:09 Syncing snapshot 57/66 #0 3/15/25 peers 3 MiB db 7 KiB chain 0 bytes queue 10 KiB sync [...] 2016-12-02 00:45:36 Imported #2730701 ad59…c8b8 (0 txs, 0.00 Mgas, 1.05 ms, 0.52 KiB) + another 2 block(s) containing 27 tx(s) 2016-12-02 00:45:48 Imported #2730702 2a08…4c17 (0 txs, 0.00 Mgas, 0.68 ms, 0.51 KiB) 2016-12-02 00:45:53 Imported #2730701 fcb0…d533 (0 txs, 0.00 Mgas, 6.60 ms, 0.51 KiB) 2016-12-02 00:45:55 Imported #2730704 a5c7…076d (19 txs, 0.47 Mgas, 12.23 ms, 3.41 KiB) 2016-12-02 00:46:04 #2677968 18/20/25 peers 5 MiB db 215 MiB chain 0 bytes queue 25 MiB sync 2016-12-02 00:46:39 #2691893 21/23/25 peers 5 MiB db 219 MiB chain 0 bytes queue 21 MiB sync ----------------------- ^ normal sync finished ------------------------------------- 2016-12-02 00:47:14 0/24/25 peers 5 MiB db 223 MiB chain 0 bytes queue 68 KiB sync 2016-12-02 00:47:20 Imported #2730707 1bc4…6d75 (0 txs, 0.00 Mgas, 0.32 ms, 0.51 KiB) + another 1 block(s) containing 2 tx(s) -------------------- ^ receiving new blocks ----------------------------------------之後，整個區塊鏈被同步並驗證 PoW。我在快速修剪模式下的設置花費了 2 個多小時，請參見上面的時間戳。
