COSS aims to resolve usability issues, related to virtual currencies, in an innovative way. The platform gathers cryptocurrency services and products into one portal allowing users to gain control over their finances, to manage transactions, to integrate merchants’ payments, to deposit funds.

At the end of February, COSS has reported that it is upgrading to ERC223 standart.

The COSS token will go through an upgrade on March 4, 2018. During the change, withdrawals and deposits of COSS token will be disabled for 24 hours prior to the swap and 24 hours after the swap. The COSS token will temporarily be removed from EtherDelta during this process, and also HitBTC will be informed to halt deposits and withdrawals while this is ongoing, but it will not impact ongoing trading.

Coss erc223 standartCOSS Announcement


  • Eliminates the problem of lost tokens which happens during the transfer of ERC20 tokens to a contract (when people mistakenly use the instructions for sending tokens to a wallet). ERC223 allows users to send their tokens to either wallet or contract with the same function transfer, thereby eliminating the potential for confusion and lost tokens.
  • Allows developers to handle incoming token transactions, and reject non-supported tokens (not possible with ERC20).
  • Energy savings. The transfer of ERC223 tokens to a contract is a one step process rather than a 2-step process (for ERC20), and this means 2 times less gas and no extra blockchain bloating.

The swap of the tokens will happen automatically and the users do not have to send the “old” COSS anywhere.

Tezos Bug to Slow Down the Network in 20 Times

The issue looks fixed now and Tezos network works in the standard transmission mode
25 September 2018   197

In the main network of the Tezos block project, a bug was discovered one week after its official launch. According to, on August 24, due to the vulnerability, the release time of the blocks increased from 1 to 20 minutes.

The user of the service for hosting IT projects GitLab under the nickname "Jérémie" reported on block freezing for 45 minutes. Later in Riot chat he learned that developers are aware of the problem and they are working on its solution.

Bug between the baker and the node. The two communicate over json but the json serializer incorrectly handled some control characters. Immediate fix was to patch the serializer. Medium term fix is that the baker and node really should communicate using the binary RPCs instead.

Soon after the discovery of the bug, one of the developers posted an urgent fix at GitHub, which was proposed to be installed by all the bakers. Currently the Tezos network operates in normal mode, and the units are released every minute.

As of September 25, 08:00 UTC network of Tezos worked in the standard transmission mode - 1 block per 1 minute
