Launches Quicksync!

Hi all!

As alot of you may have noticed, when spinning up a fullnode it can take around 3-4hours to completely sync the chain.

Chain of Secrets team has taken on the task to help the community out with offering a Quicksync service, the latest quicksync is available at

We will publish compressed & complete sync’s at different block intervals. The current quicksync is 6.7GB which we have compressed to 3.9GB.

Here are the steps to use it when setting up a new fullnode
This will save you 3-4hours of wait time

Install lz4

sudo apt-get update -y

sudo apt-get install wget liblz4-tool -y

Download & Decompress Quicksync Data after installing Enigmad & Enigmacli

cd ~/.enigmad/


lz4 -d enigma-1-block992500.tar.lz4 | tar xf -

Please note, that you may have a short time to catchup to latest block, but this will be minutes not hours.

Thanks @dbriggsie!

I’ve just upgraded a validator node from v0.0.1 to v0.03 using Quicksync and it took less than 15 minutes overall.

For future reference:

I backed up the validator’s private key:

Then I used these commands:

# the current block was ~872000
# download quicksync at block 868000
# afterward it should take no more than 4-5 minutes to catch up on 4k blocks

# stop v0.0.1 node
sudo systemctl stop enigma-node

# delete all of v0.0.1 block data
enigmad unsafe-reset-all

# remove v0.0.1
sudo dpkg -P enigmachain # might fail but it's okay

# install v0.0.3
sudo dpkg -i enigma-blockchain_0.0.3_amd64.deb

# install liblz4-tool to extract the quicksync archive
# install pv to get a progress bar for the extraction process
sudo apt install -y liblz4-tool pv

# extract quicksync into ~/.enigmad/data
# this took around 3-4 minutes for me (for .tar.lz4 file of 5.95 GiB)
pv enigma-1-block868000.tar.lz4 | lz4 -d | tar -C ~/.enigmad -x

# enable v0.0.3 on startup and start the node
sudo systemctl enable enigma-node
sudo systemctl start enigma-node

# see the catching up process until what was block ~872000 (took around 2 minutes for me)
watch -d 'enigmacli status | jq .sync_info'

Success here as well :slight_smile: Thanks @dbriggsie!
