ICO (Initial Coin Offering)
ICOs Initial coin offerings – also called token sales or crowdsales – are an unergulated, fast, high-risk, and commonly Ethereum-based crowdfunding mechanism for early-stage digital asset ventures. In ICOs, funds are raised by offering investors cryptocurrency tokens which act as a kind of voucher that may be traded for some resource or special feature of the venture in the future (e.g. storage space, datasets, etc.), in exchange for legal tender or other cryptocurrencies. ICOs might also sell investors royalties or a right of ownership to the project instead of cryptocurrency.
Mixing service breaks the link between your old address and the new one, sending funds from you to other people, and their funds to you. Therefore, transaction amounts become random, and this increases time delays due to this lack of communication between the original and destination addresses of the transactions. This process protects Your information and prevents others to track Your online payments. Bitcoin transactions are combined with a permanent public record. By blockchain, you can track transactions from one address to another.
Virtual private network
virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running on a computing device, e.g. a laptop, desktop, smartphone, across a VPN may therefore benefit from the functionality, security, and management of the private network. Encryption is a common though not an inherent part of a VPN connection.
VPN technology was developed to allow remote users and branch offices to access corporate applications and resources. To ensure security, the private network connection is established using an encrypted layered tunneling protocol and VPN users use authentication methods, including passwords or certificates, to gain access to the VPN. In other applications, Internet users may secure their transactions with a VPN, to circumvent geo-restrictions and censorship, or to connect to proxy servers to protect personal identity and location to stay anonymous on the Internet. However, some websites block access to known VPN technology to prevent the circumvention of their geo-restrictions, and many VPN providers have been developing strategies to get around these roadblocks.
A VPN is created by establishing a virtual point-to-point connection through the use of dedicated circuits or with tunneling protocols over existing networks. A VPN available from the public Internet can provide some of the benefits of a wide area network (WAN). From a user perspective, the resources available within the private network can be accessed remotely.
