ENS offers a secure and decentralised way to address resources both on and off the blockchain using simple, human-readable names.No more long addresses ENS eliminates the need to copy - and worse, type - long hexadecimal addresses.With ENS, you'll be able to send money to your friend at 'aardvark.eth' instead of '0x4cbe58c50480...',interact with your favorite contract at 'mycontract.eth', or visit a Swarm-hosted site at 'swarmsite.eth'.Secure ENS is built on smart contracts on the Ethereum blockchain, meaning it doesn't suffer from the insecurity of the DNS system.You can be confident names you enter work the way their owner intended.Truly Distributed ENS operates in a distributed fashion for both its infrastructure and governance.Anyone can register a .eth domain name for themselves by participating in an auction process, mediated by the blockchain.The commands mentioned only work because you have token javascript object instantiated on your local machine.If you send tokens to someone they won't be able to move them forward because they don't have the same object and wont know where to look for your contract or call its functions.

In fact if you restart your console these objects will be deleted and the contracts you've been working on will be lost forever.So how do you instantiate the contract on a clean machine?There are two ways.Let's start with the quick and dirty, providing your friends with a reference to your contract’s ABI: Just replace the address at the end for your own token address, then anyone that uses this snippet will immediately be able to use your contract.Of course this will work only for this specific contract so let's analyze step by step and see how to improve this code so you'll be able to use it anywhere.All accounts are referenced in the network by their public address.But addresses are long, difficult to write down, hard to memorize and immutable.The last one is specially important if you want to be able to generate fresh accounts in your name, or upgrade the code of your contract.In order to solve this, there is a default name registrar contract which is used to associate the long addresses with short, human-friendly names.

Names have to use only alphanumeric characters and, cannot contain blank spaces.In future releases the name registrar will likely implement a bidding process to prevent name squatting but for now, it works on a first come first served basis: as long as no one else registered the name, you can claim it.First, if you register a name, then you won't need the hardcoded address in the end.Select a nice coin name and try to reserve it for yourself.First, select your name: Then, check the availability of your name: If that function returns "0x00..",you can claim it to yourself: Wait for the previous transaction to be picked up.Wait up to thirty seconds and then try: If it returns your address, it means you own that name and are able to set your chosen name to any address you want: You can replace token.address for eth.accounts[0] if you want to use it as a personal nickname.Wait a little bit for that transaction to be picked up too and test it: You can send a transaction to anyone or any contract by name instead of account simply by typing Tip: don't mix registrar.addr for registrar.owner.

There are some avenues being investigated to upload the contract ABI to the network, so that all the user will need is the contract name.bitcoin php githubYou can read about these approaches but they are very experimental and will certainly change in the future.bitcoin ransom amountThere will also be an app available to reduce the barriers to participation.litecoin web minerYou can view mockups of that app here.Names will be auctioned according to a process described below.cobrar bitcoins argentinaThe value paid by the winner will be held in a deed in exchange for ownership of the name.There is no recurring fee, or subscription required to own a name.After 1 year of registration, the owner of a name is free to release it, and the full value of the deed will be returned to them.The Initial Registrar will not include any dispute resolution process.

However, some form of dispute resolution may be introduced in a permanent registrar which succeeds it.There are many options for how dispute resolution could be handled in the future, and new ones will certainly emerge after the launch of the ENS.One possible approach, for example, would require domain holders to periodically adjust the value held in a deed to match the average increase in value of all domain names.This creates the possibility that ownership of names may be revoked.Should that occur, any funds held in the deed would be returned to the owner.It is also possible that dispute resolution will not be deemed beneficial, and changes introduced in the permanent registrar would minimal, limited to tweaks to the auction process.The owner of a name may transfer ownership, along the ether held in the associated deed, to another account at any time.This will allow for secondary markets to form, providing the ideal path for a name to find an owner who can maximize the utility of a name.The release of the Ethereum Name Service, including the Initial Registrar is planned for the first quarter 2017.The Foundation will begin to accept proposals for a permanent registrar one year after launch.

The Initial Registrar is expected to be replaced within 2 years of launch.Owners of names in the Initial Registrar will be responsible for transferring their deeds to the permanent registrar.Options being considered to manage this transition include:The following events and times will be hard coded into the contract:Similar to Ethereum’s difficulty bomb, these hard dates force action and progress towards a permanent registrar.The only top level domain available will be “.eth”.Subdomains will be further limited to 7 characters or longer.For example:Note that subdomains of registered names have no restrictions.The owner of “microsoft.eth” can thus direct “foo.microsoft.eth” however they like.This restriction reserves the shortest names (which are scarce, and often most valuable) for a permanent registrar with an improved approach to name allocation.Anyone can start an auction for a name they are interested in by calling the registrar’s startAuction() function.The Initial Registrar will auction names through a Vickrey auction; bids are submitted in a “sealed envelope”, the highest bidder wins the auction, but pays the price of the second highest bid.

This format incentivizes bidders to bid what a name is worth to them.The parameters of a bid are:These parameters are salted and hashed (using shaBid()), and sent to the Registrar with a payment of ETH (using newBid()).Hashing the parameters makes it impossible to discern discern which name a bid is for.The minimum price to register a given name is 0.01 ETH.If no one else bids against you, that is how much you will pay.During the normal operation of the registrar, the bidding period will last for 3 days.In order to allow people sufficient time to prepare for bidding, all auctions started during the first 25 days of the registrar’s life will extend until the end of the 28th day.After the 3 days of bidding, is a 48 hour reveal period, during which bidders must submit the parameters of their bid (using unsealBid()).New bids are not accepted during the reveal period.Bids revealed after the reveal period has ended will be invalid, and the value of the deed will be lost.After the reveal period has passed the winner will be set as the owner of the name (using finalizeAuction()).In the event that two parties bid exactly the same value, the first bid revealed will win.Non-winning bidders will receive a 99.9% refund on the value bid.
