Komodo's blockchain security service offers protection against 51% attacks by leveraging the Bitcoin network, ensuring that integrated blockchains are safeguarded at a minimal cost. Since April 2018, multiple successful 51% attacks have resulted in over $23 million in losses, highlighting the vulnerability of many blockchain projects. By using Komodo's delayed proof of work (dPoW) mechanism, blockchain projects can achieve enhanced security and focus on development efforts while mitigating risks associated with these attacks.

Blockchain
Security Service
Security is the foundation of every single blockchain.
Without adequate security, a blockchain project cannot thrive. Any
project built atop an unsturdy foundation can be brought to collapse
at any moment.
Fortunately, there is an easy solution. Komodo’s Blockchain Security
Service protects every integrated blockchain with the power of the
Bitcoin network, for a tiny fraction of the cost.

2. A Brief History of 51% Attacks
Until the beginning of 2018, the notion of a 51% attack was merely a
theoretical problem.
While Satoshi Nakamoto noted in the original Bitcoin white paper
that a Proof of Work (PoW) blockchain is only reliable “as long as
honest nodes control the network,” not a single 51% attack had been
successfully executed.
All of that changed in the spring of 2018. A wave of successful attacks
over the last 12 months has proved that the threat is very real.
Below is an overview of all the 51% attacks that have occurred in the
blockchain space since April 2018.
Project Date Loss
Verge (XVG) April 4, 2018 ~$1.1 Million
Monacoin (MONA) May 14, 2018 ~$90,000
Verge (XVG) May 22, 2018 ~$1.75 Million
Bitcoin Gold (BTG) May 29, 2018 ~$18 Million
ZenCash (ZEN) June 2, 2018 ~$550,000
That’s 10 successful 51% attacks for a total of more than $23 Million in
losses, with an average loss of $2.5 Million per attack.
Litecoin Cash (LCC) June 4, 2018 Unknown
Flo Blockchain (FLO) Sept 8, 2018 ~$27,5000
Aurum Coin (AU) Nov 8, 2018 ~$500,000
Vertcoin (VTC) Dec 2, 2018 ~$100,000
Ethereum Classic (ETC) Jan 7, 2019 ~$1.1 Million

3. Blockchain Vulnerability
10 successful 51% attacks
caused more than
$23 Million
in losses to blockchain projects.
The unfortunate reality is that many blockchains are extremely
vulnerable. With hash power rental sites like NiceHash, attackers
don’t even need to make a costly investment in hardware to carry
out a 51% attack. Sufficient hash power can be rented anonymously
online.
To make matters worse, the cost of renting adequate hashpower to
execute a 51% attack is staggeringly low. Dozens of projects can be
attacked for just a few hundred dollars an hour.
For these reasons, blockchain attacks are becoming more and more
common. Since April 2018, there have been 10 confirmed 51% attacks.
The average financial loss from one attack is more than $2.5 Million—
and that only accounts for the value of the stolen coins.
In addition to direct financial losses, a successful 51% attack causes a
number of other immeasurable losses an attack causes, such as:
• being delisted from exchanges
• a surge of negative press coverage
• reduced confidence in the blockchain
• a substantial reduction in the price of the currency
• decreased likelihood of future investment
A successful attack is a catastrophic event for any blockchain project.

A Growing Security Alliance
Einsteinium network experienced a real 51% attack.
Komodo dPoW, that we implemented in our code
recently, kicked in and protected the chain. We are
very pleased that this solution worked well and that
Einsteinium chain is protected from any attacks in the
future.

In addition, CoinBene, one of the world’s biggest digital
asset exchanges, officially endorses Komodo’s Blockchain
Security Service as the industry’s leading security solution.

6. Komodo’s Blockchain Security Service is powered by the innovative delayed
Proof of Work (dPoW) security mechanism. A global network of 64 dedicated
Notary Nodes perform a series of cross-chain notarizations to protect every
integrated blockchain with the power of the Bitcoin hash rate.
Your blockchain’s network still determines the truth of your blockchain.
Komodo’s Blockchain Security Service simply makes that truth immutable.
An Extra Layer Of Security
After the notarization from your blockchain to KMD is complete, you receive an added
layer of security. Attackers cannot re-org any blocks that were mined prior to the
notarization, uinless they first overpower the KMD network and alter the block hash
that was notarized onto the KMD ledger.
Notarization From Your Chain To KMD
The block hash of a block in your blockchain is saved onto the KMD chain by executing
a transaction and using the OP_RETURN command. This occurs every 10 minutes.
Notarization from KMD To BTC
The block hash of a block in the KMD blockchain is notarized onto the BTC ledger. This
also occurrs roughly every ten minutes.
Bitcoin-Level Security For All
Once a notarization to the Bitcoin ledger is complete, all blocks and transactions that
occurred prior to the most recently-notarized block receive Bitcoin-level security. To
succesfully execute a 51% attack, a hacker would need to overpower your blockchain’s
native network, the KMD network, and the BTC network— all at the same time.
Constant Protection
Since this series of cross-chain notarizations takes place every 10 minutes, your
blockchain is constantly protected. There is never an opportunity for an attack.
A Decentralized Security Solution
Komodo’s Blockchain Security Service uses a global, publicly-elected network of 64
Notary Nodes. Each of these dedicated servers runs a full node of your blockchain,
increasing the hash rate and decentralization of your network. At the same time,
Notary Nodes have no special powers or control of your blockchain. They simply take
the verified history of your blockchain’s ledger and make it completely immutable.
