My node is 8000 blocks behind, and its taking quite a while to sync. Is there a faster way to sync / download the Monero blockchain?

  • Downloading and importing the blockchain is slower in most circumstances than letting it sync on its own. – sgp May 1 at 16:02
  • how is that possible? Even if I downloaded the monero blockchain at 1 gbit and then imported it? – Patoshi パトシ May 1 at 18:07

You can download the blockchain and then import it using the instructions here:

I've got same problem setting up my local Monero node. I've started downloading it, but as size increase I could not afford to host it on my laptop. So I choose to host it on a VPS, a small one so it wouldn't be expensive.

On Linode the VPS main disk it's a SSD, but could't be expanded for more space, so I have to put the blockchain into a separate disk and unfortunately on Linode they are very slow.

I've setup first a bigger VPS with 160 SSD, then download the cli and setup a configuration:

# Data directory (blockchain db and indices)
data-dir=/home/monero_wallet/data

# Log file
log-file=/home/monero_wallet/data/bitmonero.log
log-level=0

# Deatached
# detach=1
# non-interactive=1

# Mining
start-mining=
bg-mining-enable=1
bg-mining-ignore-battery=1
bg-mining-miner-target=35

# P2P full node
p2p-bind-ip=0.0.0.0            # Bind to all interfaces (the default)
p2p-bind-port=18080            # Bind to default port

# RPC open node
rpc-bind-ip=0.0.0.0            # Bind to all interfaces
rpc-bind-port=18081            # Bind on default port
confirm-external-bind=1        # Open node (confirm)
restricted-rpc=1               # Prevent unsafe RPC calls
rpc-login=user:pass            # RPC login
no-igd=1                       # Disable UPnP port mapping

# Slow but reliable db writes
db-sync-mode=safe

# Emergency checkpoints set by MoneroPulse operators will be enforced to workaround potential consensus bugs
# Check https://monerodocs.org/infrastructure/monero-pulse/ for explanation and trade-offs
enforce-dns-checkpointing=1

out-peers=64              # This will enable much faster sync and tx awareness; the default 8 is suboptimal nowadays
in-peers=1024             # The default is unlimited; we prefer to put a cap on this

limit-rate-up=1048576     # 1048576 kB/s == 1GB/s; a raise from default 2048 kB/s; contribute more to p2p network
limit-rate-down=1048576   # 1048576 kB/s == 1GB/s; a raise from default 8192 kB/s; allow for faster initial sync

Then download the raw chain, import it without verification.

$ ./monero-blockchain-import --log-level=1 --input-file ./data/blockchain.raw --data-dir ./data --dangerous-unverified-import=1 --resume=1

After this step was completed I've started the monerod node and sync-up with rest of the network.

$ ./monerod --config-file=/home/monero_wallet/data/bitmonero.conf --detach

When everything was done, I've created a disk at 100GB and moved all files there. Then started again a monero node.

$ mv /home/monero_wallet /mnt/monero_wallet/wallet -v

And downgraded my VPS to a cheaper one. I did this because I wanted to minimize the cost which are around 15$. But you can just setup a VPS and start the node.

The whole thing took almost a day, it would be faster to just use an open node, but wouldn't be of help if you want to use Monero for long term.

You can do the following to speed it up:

./monerod --block-sync-size 1

    That speeds it up, or slows it down ? – user36303 Feb 7 '18 at 9:24
  • block-sync-size default is 20, so setting it to 1 slows it down.... – onefox Apr 25 '18 at 21:15

Using a Monero client and syncing the blockchain via peer-to-peer will probably be a lot faster than trying to download blockchain.raw.
