Two projects sell Christmas cards and the earnings in euros, dollars and cryptocurrencies will be delivered to families in Venezuela and to children in Spain

Greeting a loved one at the distance and expressing love and good wishes in Christmas, through apostcard, is a tradition that has not been completely lost.

This year, two initiatives of the Ethereum technology will not only make possible to send Christmas cards to family and friends, but also raise funds to contribute to noble causes such as financing the creation of activities to pull at peoples heartstrings in virtual reality spaces for hospitalized children and elderly people with some type of disability, which is made by a non-government alorganization called Voluntechies.

It is a leap into the digital era and a charity event promoted by the Ethereum company. The Spanish laboratory specialized in blockchain technology NWC10Lab and the creativeagency CLV, created the first of these two projects, which is called Christmas Blockchain.

To access this function, interested people should only visit the website:, where users can send their digital Christmas cards registered on the Ethereum block network to their loved ones.

Hence, one particularity of the blockchain and Ethereum networks is to guarantee the unique character of the objects that are created on these platforms, in this case, the Christmas cards. This is how, by using HASH codes, each card sent or developed is unique and original to that loved one. Similarly, its social valuemakes it special.

How to Send those Christmas Cards?

On the official project page, it is indicated that users interested in using the service can choose between four available designs. To do this, they must select the model they like the most and click on the “Continue” button.

Once the design is selected, a window appears in which the postcard is customized. To do this, it is necessary to provide the names and emails of both the sender and the recipient. Just in this area there is an additional section in which the participant can write the message he wants to send on the digital card.

The next step is for the user to indicate the amount of money in euros he wishes to donate for the postcard. The minimum amount is one euro and the donation is made through PayPal, following the “Donate” button. The developers of the project assure they work so that the donations can also be made with Bitcoins.

Once the payment is confirmed, the respective card is sent to the recipient through the previously indicated email, where the message will be outlined along with the amount donated to Voluntechies, and a QR code with the HASH of the postcard.

In addition to Christmas Blockchain, the NWC10 Lab team has other projects which use Ethereum’s Blockchain technology, such as Bit2me, Tikebit, Blocknap, Muchacomida and100Thanks.

Cryptoxmas is the name of the second initiative for sending Christmas postcards. This platform uses Ethereum’s smart contracts to create a non-fungible (collectible) token that is sent to the honorees along with a small amount of ETH.

To decorate the card, Cryptoxmas designers donate their art and each of these images represents a token. The funds that are sent next to each token are destined to cover the gas of the network and to donations destined to 100 thousand families in Venezuela. Each one of them will receive USD10.

To distribute the donations, CryptoXmas works jointly with the organizations Bitcoin Venezuela and Airdrop Venezuela. It also forged alliances with crypto community members such as Raiden and Trust Wallet.

 This DApp was built on the decentralized charity platform Giveth. In November, the DecentralizedAltruistic Community (DAC), also built in Giveth, channeled financial contributions to projects that won the Blockchain4humanity (b4H) 2018 awards,held in Chile, from December 5th to 8th.
