Nano Boulton's upgrade is impressive, EOS dapps is a haven for hackers while DASH and Venezuela still love

Several EOS gambling games were attacked on December 18th^th
according to PeckShield, a technology security company.

A hacker using an address called "panming12345" attacked the EOS TRUSTBET game and transferred 11,501 EOS to his Huobi exchange account. After that, even a game called EOS Max suffered a hack, with an address "eykkxszdrnnc" that attacked the game contract and siphoning 55.526.05 EOS. The third gaming platform called ToBet was hit by a "kfexzmckuhat" address and, as a result, lost 22,000 EOS.

Finally, the biggest attack of the day was immediately
BetDice, which lost about 200,000 EOS for the hacks. BetDice has released a
detailed explanation of the attack:

"We would like to provide more details about the attack
that happened today.
The attack started at 17:00 UTC and we noticed the suspicious activity a
17:45 UTC. At 5:55 pm, we performed an emergency stop, judged the attack on
be a non-contractual problem and immediately contact the BP for further
investigation, while also contacting other dapps who were under attack
avvisali.
We have submitted our contract to the BP for review. The conclusion was that ours
contract is very secure and has no loophole that could be abused.At 21:00 UTC, we reached a conclusion and confirmed the nature of
l & # 39; attack.
The hacker has discovered a way to exploit the EOS nodes. Transactions not in a
irreversible block could be exploited due to the time required for synchronization between the
API Node and BP Node. They used this exploit to place bets, but only to assert
transactions in their favor. In short, they would only have presented the transaction
to the BP node if it was a winning transaction. This attack was not due to a
vulnerability at the contract level.
Since the attacker used many accounts, the actual loss is still undetermined,
but it is estimated that around 200,000 EOS have been lost. Even if this loss is not
negligible, it does not affect our functioning at all. We can easily resist
more than 500,000 EOS losses, which is still only a small part of our funds. "

The crucial point of the
the problem is apparently found in the dApps that used their own node; these knots were producing
side effects before being included in an "official" block producer
to block. This allowed an attacker to send only winning transactions to BP
nodes, without losing transactions. Later it was confirmed that this
the vulnerability was the cause of all the other hacks. A solution was
found to avoid further hacking (in addition to banning the accounts of confirmed hackers
from the main network) and it necessary
for dAapps to run its own node that had its read mode set to read-only.

L & # 39; attacker
eventually distributing the stolen funds through thousands of EOS accounts, with
every account that stores 60 EOS. This move makes it difficult to track down the
funds and return them to their original owners. Even if it were possible
track down everything that was stolen, EOS actually reversing its blockchain
the transactions will add further fuel to the project's fire
centralized. These last errors represent the continuation of a trend of the EOS dApps
exploiting their vulnerabilities, with over 13 different gambling games
be attacked in the last 30 days.

• CCID Ranking Public Blockchain Round 8
  released

Chinese ministries
of Industry and Information Technology own research institute CCID
has released the 8^th interpretation of his increasingly popular audience
evaluation index of blockchain technology.

In this last
Release of the CCID index, EOS managed to keep the spot n. 1 with board best
156 index points to it. As a reminder, CCID classifies the cryptocurrency projects into
the areas of basic technology, applicability and innovation; certainly, these all
it seems rather vague and the ratings are debatable at best, as some members of
the community insinuates that there could be favoritism involved in the evaluation
process.

However, the votes
I'm out and EOS apparently has the best basic technology on the market, with 106.4
points in this parenthesis. Applicability scores are low across the board, with
28.8 of Ethereum makes it the most applicable cryptocurrency. Innovation score
they are not so tall, but interesting enough Bitcoin runs away in this
category with 36 points.

Overall, the top 10 seems
thus: EOS (156.0), Ethereum (136.5), GXChain (117.4), Komodo (112.7),
Ontology (112.6), NULS (112.2), Nebulas (111.4), BitShares (110.3), NEO
(108.3) and Steem (107.0). The most popular cryptocurrency on the market, Bitcoin,
sits on the 18th^th point with 96 points.

• The adoption of Dash in Venezuela is growing: 2500
  merchants who accept the currency

Dash and Venezuela
they are becoming two synonyms terms, as the country has recently seen the number of
Dealers who accept the dashboard go up over 2500. The number can be confirmed by looking
on the Dash merchant's ad site, DiscoverDash, which currently displays
2534 total dealer list in the country. Whereas the second closest
country in terms of merchant distribution is United States with 530 merchants, Venezuela
is by far the biggest connoisseur of this cryptocurrency / payment solution.

Overall, with the
total number of Dash merchants in the world sitting around 4500, Venezuela
represents more than 50% of that number. The transaction activity also has
increased, according to the head of Dash Merchant Venezuela, Alejandro Echeverría. Daily
transaction counts have increased several times (currently sitting at
hundreds a day), he said in a recent interview.

"This was possible thanks to the municipality
efforts of all the teams here doing promotion, especially our activities for
"Incentivize consumption" (third phase of our strategy for adoption) where
merchants offer discounts, promotions and support them on the spot. In addition to
the influencer campaign we did on Instagram was very successful and this has created
even more awareness " he
added.

Much of the increase
has been linked to the recent take-off of KRIP mobile phones, at low cost
smartphone pre-installed with a variety of Dash apps including a Dash
portfolio, gift voucher service Bitrefill and the Uphold brokerage app. These
the phones are joined to pre-loaded paper wallets with small amounts of Dash that
allow the user to integrate seamlessly into the Dash ecosystem. Relationships
suggest that over 66,000 KRIP mobile phones have been sold since the beginning
this month, potentially taking into account thousands of new portfolios created.

• NANO Boulton active and functioning

Finally dwarf
around to release the v17 upgrade (Boulton) and brought several interesting
new features with it.

Lazy bootstrap
it has been long awaited and has been officially launched. Thanks to
this feature, the Nano software is now able to intelligently download the ledger,
and then reduce the time it takes to start participating in the network using
the Nano node. The team has already teased further improvements in the v18 it should
come with "local account priority", a function that will update nodes
much faster after long periods of inactivity.

Other improvements
to include:

• RPC stability:
  it should bring more performance and stability in RPC calls
• Reduced
  use of resources: some functions of v17 are activated only when other nodes v17 are provided
  online to talk to each other; this reduces the bandwidth and use of resources on
  knots

The dwarf team has
has already started work on the v18 update (Dolphin) and will share more details on
that in the near future.
