Blockchain has made possible the growing popularity of cryptocurrencies. Blockchain is basically a highly secure digital ledger that is decentralized.

The blockchain startup Tezos want to take this technology even farther.
Tezos is a new crowdfunded blockchain. It allows for consensual upgrades to its protocols, which empowers it to govern itself via what the Tezos white paper calls a “self-amending” cryptoledger. “It facilitates formal verification, a technique which mathematically proves the correctness of the code governing transactions and boosts the security of the most sensitive or financially weighted smart contracts,” Tezos claims.
Now, to get it’s blockchain up and running, Tezos is running an “initial coin offering” (ICO) through Bitcoin and Ethereum funding. At the time of this writing, the Tezos ICO has already received 53,418 Bitcoins and 273,068 Ethereum. That’s roughly $207 million at current valuation, making the Tezos ICO the largest “crypto-funding” to date. Moreover, the Tezos ICO is uncapped — there’s no upper limit to how much funding the company can raise, given the remaining eight days of crowdfunding it has left.
