Skycoin has been expanding off of bitcointalk.
Main page [WIP] -> https://www.skycoin.net
Blog -> https://blog.skycoin.net
Telegram -> https://t.me/Skycoin
Source code -> https://github.com/skycoin
We are most active in Telegram now.
We would use Slack too, but their app is so slow I can have 200 open tabs in a browser no problem but when I open slack everything goes to shit. Telegram sucks in general but does is not digital sludge. Whatever happened to IRC?
This thread was also real but was a mistake. It is not scam. Skycoin has never scammed anyone. You think we write software for years to run scam? We are capable of building a new coin from scratch with its own consensus algorithm, but we are too stupid to scam you like many other coins have done? The reason you get scammed is because you cannot read, you cannot tell difference between real coin and scam, so you call Skycoin a scam and buy bullshit.
Skycoin has things together for marketing and promotion now. Sorry we did not try to lie and hype you with no product first. I recommend you join the telegram group for updates.

Lost me Here: Skycoin has no mining
Good Luck.
Good Luck.
Mining is a security flaw. Satoshi's original vision was for a decentralized cryptocurrency. The Bitcoin network is controlled by three mining pools. At one point Gigahash.io controlled over 65% of the network.
The objective of the Skycoin project from the start was to fix the problems in Bitcoin. This includes redecentralizing consensus over more than three people.
For security and incentive reasons, the blockchain consensus network has to be independent of coin creation. It is suicide to link coin creation to whoever controls the consensus network. Unless you want a "decentralized" coin whose consensus network is controlled by three for profit mining pools (who are basicly a cartel now, who splits ASIC costs and divides the hash power between themselves by agreement).
The idea behind mining is that whoever has the most money, to buy hashing power should own and control the consensus network. "Whoever has the most money should own the government and make the laws".
The original premises (economic and human) required for the security of PoW established by Satoshi have been shown to be empirically false in reality.
Right now, eliminating mining seems absurd. In the future, that mining was accepted will be absurd. People only support the cost of mining as long as they make money from it and the price is going up.
Another objective for Skycoin, was to have transactions that were as fast or faster than credit cards. We are able to do 10 second blocks. In order to do that, PoW and PoS has to be eliminated. Decreasing the block time decreases securities for PoW/PoS coins.
Additionally, mining costs the Bitcoin network tens of millions of dollars per month and does nothing that anyone is willing to pay for directly. Bitcoin requires an exponentially growing influx of new users and capital to offset the mining costs. No one would use Bitcoin if they had to pay the mining costs directly and each transaction cost $50.
Skycoin transactions do not cost $50 in inflation from new coins being created every block.
It is my opinion that in the long run, we are going to see all the existing Pow/PoS coins die as people realize the actual economic incentives. The cost of PoW/PoS mining is bounce by the users and paid for in a lower market valuation as money is bled out of a coin by mining costs until the coin is abandoned. Only a few coins, like Bitcoin and Ethereum can achieve enough new users coming in with new money to offset hundreds of thousands a dollar a month to tens of millions a month in electricity costs, just to process seven transactions per second.
The price equation is simple
- this may dollars per month are coming in from new users and capital inflows
- this many dollars per month are being thrown in a pit and burned by mining costs
We are moving away from "free coins for miners" and moving towards "community coins" and treating cyptotokens as digital property and a type of equity. The objective is to make the coins useful and that people doing useful work people are willing to pay for should get coins.
Right now the Bitcoin economy consists of new users putting them money in and then the money being thrown in a pit and burned in a sacrifice ritual to the mining electricity costs.
If the average user had to paid the miners electricity cost directly as transaction fees, instead of it being robbed from them through inflation by the creation of new coins, then each Bitcoin transaction would cost more than $50. It would be more expensive than an international bank transfer.
Achieving mathematically provable consensus in a decentralized way, without the cost ($50 per transaction) and problems of PoW/PoS is a cornerstone of the Skycoin project. Solving the PoW cost problem is a requirement for stability and mainstream adaption of crypto assets.
Skycoin is not premined, because Skycoin does not have mining. The objective of the Skycoin consensus algorithm was to eliminate the miners and the downward pressure they create on the coin price.
The most important thing about mining however, is that when everyone had a GPU miner in their house and was getting coins, it was "decentralized". Now that ASICs and three mining pools dominate the network, there is nothing for the Bitcoin community to do or participate in. It is no longer fun and relevant. Its not fun anymore and people are unable to participate in mining in any meaningful way. This is what has driven a lot of the activity and community out of Bitcoin and into the altcoins.
We need a new model for people to get coins.
Welcome to Skycoin!
This is the official channel for information on the release of Skycoin (SKY).
About Skycoin:
Skycoin (SKY) is a next-generation cryptocurrency. Skycoin has no mining, no scripting language, and no 51% or DDoS vulnerability. It is a pure coin that has been designed from the ground up to resolve key structural issues in the current generation of digital currencies and create a sustainable, immutable value store.
Skycoin is also the currency of Skywire. Skywire is the new distributed Internet, designed to distribute content quickly, safely, and anonymously. Skycoins will be distributed over time to participants in the Skywire network who provide connectivity and services.
Key Features and Benefits:
- Security and Privacy: Skycoin has been designed from the ground up in Golang, using time-tested cryptographic standards.
- Usability and Sustainability: Skycoin uses neither proof-of-work (POW) nor proof-of-stake (POS), featuring the first new consensus algorithm since PeerCoin. The new network consensus algorithm is based on Ben-Ors decision procedure. This facilitates two key benefits:
- Not just a coin: Skycoin tokens are both a cryptocurrency and a token.
- Supply and Distribution: The total supply of Skycoin is capped at 100 million coins. They can neither be created nor destroyed, and are totally immutable. Skycoins will be disbursed to participants in the Skywire network who provide connectivity and services.
About Skywire:
Skywire is the new Internet. It is designed to distribute content faster, safer, and anonymously.
It is composed of 2 key components: Aether, a peer-to-peer replicated object system, and Skynet, a distributed networking backbone.
Aether powers the distribution of immutable, anonymous web content. Applications include video streaming, message boards, chats, and any other service that can be created on the traditional Internet.
Skynet is a source routed, public MPLS network which allows every user to essentially become their own ISP. It is built on a whole new networking stack and in its own namespace.
While Aether and Skynet can run independently, their full potential is reached when they are combined to create a truly indestructible network.
Progress
Skycoin and Skywire has been in development for over 4 years. We are at the precipice of our initial release. Stay tuned for access to exclusive ICOs and demos of Skywire technology.

Extremely interested in anything to do with Meshnet and am interested in this , more info is good read and you have me interested !!
Yes. The meshnet is very excited.
We do not have the meshnet whitepaper on the website yet, but the three consensus whitepapers are online.
- http://skycoin.net/whitepapers.html
The "meshnet" Skycoin is not actually a meshnet. It is a new type of modular software defined networking, that could be used to build meshnets or community ISPs. It is also very useful for machine-to-machine communication, IoT and building VPN clients.
It is actually not even possible to build one of these networks on top of IPv4 or IPv6, because meshnets require features like route selection, multihoming, store-and-forward, connection fall over and have to have mathematical properties that IPv4/IPv6 networks and routing do not have. We proved early that it is mathematically impossible to meet the technical requirements in a stateless routed network (ruling out IPv4, IPv4. BGP), so this is a completely new networking namespace and essentially a new internet build on top of the existing internet (for now, until people run physical cables).
We are also doing experiments in content addressable storage and source independent networking. Which will be essential for fully taking advantage of this new type of networking.
Here some infographics.
The meshnet is basicly working, but we have not finished the first applications yet.
lol. This is one of our marketing channels. I told him "SkycoinOfficial" was a stupid name.
He need to work on the name.
The marketing people are supposed to push weekly updates into each of the social media channels.

Sigils: Graphical Representations of Deterministic Wallet Seeds
This is a proposal for a graphical representation of 256 bit deterministic wallet seeds, in a form that can be committed to memory more easily than a 64 character hex string. It is designed to be easy to write down on paper, with human checkable error correction coding to reduce transcription errors.

Future advances in mathematics may render Bitcoin insecure. This is a draft protocol for securing cryptocoin transactions against future advances in mathematics or computing which render discrete logarithm based public key cryptography insecure.
TwoStep is part of QuantumEclipse, a suite of next-gen cryptocoin protocols developed under OP Darknet Plan for the Skycoin Project.
This protocol is
- simple
- adaptable to Bitcoin
- lower overhead than Lamport Signatures
- works with SHA256 preimages equally as well as Secp256k1 signatures
- not dependent on the security of discrete logarithm based public key cryptography
Overview:
Protocol:
1> A user creates a transaction and publishes the SHA256 of the transaction onto the block chain
2> The user waits several blocks and publishes the transaction. Miners enter the transaction onto the block chain.
A transaction has a pre-published hash it is "timestamped" by the publication of the hash. A transactions without a prepublished hash is a "non-timestamped" transaction.
Rules Followed by Miners:
- if an unconfirmed non-timestamped transaction spends outputs used by a non-confirmed timestamped transaction, the non-timestamped transaction is invalid (time-stamped transactions have priority over non-timestamped transactions).
- if two unconfirmed timestamped transactions spend non-disjoint sets of unspent outputs, the transaction with the earliest timestamp is the valid one.
Analysis:
This protocol relies on
- address pub keys are not published until they are first used in a transaction (address non-reuse)
- private keys cannot be recovered from public keys until the public key is published (preimage resistance of ripmed120(sha256(sha256(x))) )
- the publication of transaction hash into the block chain is a reliable timestamp (no 51% attack, total ordering on transactions)
This protocol delays the publication of the public key for an address until transaction publication and then renders any transactions an attacker creates from the recovered private key invalid.
The attack must now recover the private key, 51% attack the block chain to orphan the user's timestamp and enter an earlier time-stamp for his transaction that would steal the Bitcoin. The longer the user waits between the publication of the hash and the publication of the transaction, the more difficult the required 51% attack becomes.
Integrating into Bitcoin:
Skycoin supports this protocol naively. Bitcoin requires a small modifications to support TwoStep.
- We need an op code for the publication of transaction timestamps. The OP code should include a time or block number when the hash expires. The expiration should be capped, to allow pruning of old timestamps.
- Miners should obey the two precedence rules. The protocol is only secure if miners do not collude with people who are able to recover secp256k1 private keys from public keys.
Weaknesses:
There is no way in Bitcoin to enforce precedence rules if miners are dishonest. There is no way in Bitcoin to prove that a particular block violated the precedence rules. Bitcoin can therefore only support soft/voluntary precedence rule enforcement. There is no mechanism in Bitcoin to blacklist provably dishonest miners.
Enforcement of TwoStep transaction protocols requires new cryptocoin blockchain primitives. The Skycoin Obelisk whitepaper will introduce two new block chain primitives which enable "hard" enforcement of transaction precedence rules.

Summary
Skycoin is a third generation cryptocurrency. The Skycoin project is a long term infrastructure project that began around the time Litecoin was launched. Skycoin is designed a successor to Bitcoin.
Skycoin is focused on implementing Satoshi's original vision for a cryptocurrency. Satoshi originally intended the Bitcoin network to be decentralized, over hundreds of thousands of computers. Today, the Bitcoin network is completely controlled by three mining pools. Bitcoin is no longer decentralized. Skycoin Project has developed a new consensus algorithm to achieve true decentralization.
In addition to fixing the outstanding technical issues with Bitcoin, the Skycoin Project is implementing a new next generation of foundational networking, storage and application primitives (a new internet). We believe that "blockchain" is just one of several new mathematical and algorithmic primitives, which will underly the foundation of the successor to the current internet.
- CX is the Skycoin Project's computation primitive (analogous to EVM, Solidity, Go, C/C++, Rust)
- CXO is the Skycoin Project's peer-to-peer immutable data storage and replication primitive (analogous to IPFS)
- Skywire is the Skycoin Project's communication primitive (analogous to MPLS, open-flow, TOX, mesh networking, darknet, i2p)
- "Skycoin" is the Skycoin Project's blockchain primitive, token and transaction infrastructure (analogous to Bitcoin, Ethereum, etc)
The Skycoin Project is not a simple blockchain project, but is designed as a platform and foundation infrastructure for supporting an ecosystem of applications.
=== Skycoin (SKY) ===
The Skycoin Project Coin (SKY) is focused on core features, security, usability and simplifying Bitcoin instead of adding features as a marketing gimmick.
There are still major outstanding problems with Bitcoin and those are the problems we are addressing.
- Elimination of the need for miners for network consensus through new algorithms, elimination of dependence on the human element in the network operation
- Duplicate coinbase outputs
- Signature malleability
- Reduction in complexity in implementation
- Dozens of security/crypto related improvements
- Elimination of external dependencies that create security concerns in Bitcoin
- 51% attack proof and strengthening against various attacks
- Simplified, more powerful data, transaction and wallet APIs
- Brainwallet, deterministic wallets as default
- Network security improvements
- Intrinsic support for gmaxwell's CoinJoin transaction privacy protocol
- New networking protocols to enable the verification of the mathematical prerequisites for consensus network convergence
- Separation of coin creation from the consensus network, to eliminate Bitcoin's tendencies towards mining centralization
- Directed bipartite TX/UTXO transaction graph structure which is more elegant and efficient than Bitcoin's multi-graph structure
- Provably upper bounded network, RAM and CPU resource usage for network operation
- Soft coded, adjustable blockchain size parameter to enable network transaction rate scaling
- Rolling unspent output state error correction coding in the block header for early detection of software/hardware non-determinism
- Blockchain/transaction/histrory storage database with constant time lookup, indexless operation for all major blockchain history queries
- Etc...
Skycoin is 51% attack proof and addresses many of the security issues in Bitcoin. Skycoin is designed to be a simpler, easier to use, more secure Bitcoin. Skycoin emphasizes simplicity, security and usability.
Skycoin is a major research undertaking and has taken several years. We are finishing up phase one of project implementation and then focusing on services and driving adaption.
Skycoin is being developed in collaboration between AKS, Myth and Syndicate under Darknet Plan and OP Redecentralize.

Skywire Meshnet Whitepaper
https://blog.skycoin.net/overview/skywire---skycoin-meshnet-project/
---
Obelisk is what makes Skycoin "Bitcoin 2.0". Obelisk is a sustainable alternative to proof-of-work. Obelisk is a system that replaces proof of work for blockchain consensus and eliminates the possibility of a 51% attack.
Obelisk was inspired by academic research into adversarial distributed time-stamping and algorithms such as Ben-Or's, Paxos, and the Castro-Liskov PBFT algorithm. Obelisk is a new solution to the Byzantine Generals problem which offers strong mathematical security guarantees, even when the majority of nodes are hostile.

- Obelisk technical explanation: https://blog.skycoin.net/overview/obelisk-skycoin-consensus-algorithm-information-pages/
---
Skycoin cannot be 51% attacked. No matter how much money or hashing power an adversary has, they cannot reverse transactions.
Skycoin Transactions are fast. Obelisk and specific design decisions may allow Skycoin to achieve transaction confirmation times as low as four seconds, without compromising security.
Skycoin does not waste electricity or consume exponentially growing, unsustainable amounts of electricity unlike Bitcoin.
Skycoin has no transaction fees. Users receive "coinhours" for holding coins, which are used for paying transaction fees. Transactions bid to enter a fixed sized block.
Skycoin transactions offer increased privacy. Skycoin is designed for advanced CoinJoin support.
---
Besides building a better, more robust, most secure, more usable Bitcoin, the Skycoin project is working towards several long term goals we believe are necessary.
Skycoin Darknet Project:
- Users receive Skycoin for contributing resources to network and expend skycoin for consuming resources
- Almost as secure as TOR/I2P, but with much high bandwidth throughput.
- Very difficult for ISPs to identify and throttle
- Inspired by cjdns
See: https://github.com/skycoin/darknet
Skycoin Meshnet Project:
- Uses Skycoin Darknet protocol over wifi mesh network
- Uses receive Skycoin for providing transit
- bridge the "last mile" between homes and fiber with a distributed wireless mesh networks and community ISPs.
- SOPA, PIPA, ACTA and the Comcast/Time Warner merger have made it clear that political solutions are no longer viable.
---
Development Process:
All Skycoin components are written in Go (Golang). There are multiple teams working on Skycoin and multiple independent software components required to achieve the long term vision of the project. This is an open source project.
Substantial coins are reserved and available for developers who want to contribute to the project.
---
Team:
https://blog.skycoin.net/statement/skycoin-team/
---
Design:
Skycoin tries to offer more security, greater privacy and better usability than Bitcoin.
Skycoin Philosophy:
- Complex systems cannot be secure
- Simplicity over complexity
- Decentralized but pragmatic
- Emphasis on usability
----
Partial feature list:
Security:
- Higher level of security for non-technical users with improved ease of use
- Deterministic ECDSA, enforced signature mutability
- Hardening against SHA256 pre-image attacks, hardening against side channel attacks
- Hardening against "offline" attacks on secp256k1
- Optional quantum computer resistant TwoStep protocol transactions
- Standardized remote signature HMAC API for hardware wallet devices
Privacy:
- Skycoin transactions have higher privacy than Bitcoin transactions ("wallet mixing", "money pot")
- Skycoin protects its users from identification for increased safety in hostile countries (ex. HTTPS/TLS tunneling)
- Stenographic wallets
Usability:
- Wallet supports Bitcoin and Skycoin
- 15 second transactions (point-of-sale)
- Simple 256-bit deterministic wallets
- Clients only need unspent output set instead of whole block chain ("Snapshot")
- Coins divisible to 6 places
Distributed Exchange:
- Off blockchain Transactions (through standardized API, "gateway")
- Powerful scripting language for contracts (non-turing complete statically typed LISP variant)
- Open Transactions type crypto-equities, bonds, options and other securities
- OTC gateway API (based upon FIX, SWIFT, FIXatdl)
The blockchain is for settlement between counterparties. Price data and bid/ask orderbook data is not in the blockchain, but supported through the gateway API. Fractional Skycoin transactions and micropayment are handled as off block chain transactions.
---
No Mining:
Satoshi has stated that mining is Bitcoin's only flaw. Miners are the greatest non-crpytographic threat to Bitcoin retaining value on geographic time scales. Mining introduce human factors and greed into the survivability of Bitcoin as a currency
- Dishonest miners may destroy Bitcoin
- We are close to a 51% attack
- gigahash.io has abused its hashing power to steal Bitcoin from gambling sites
- Services such as cex.io allow people to rent a 51% attack by the minute
- Mining pools will form cartels to orphan blocks mined by non-cartel members, to enhance their block rewards
- Mining cartels will rent capacity to orphan blocks from other pools, if the reward is greater than the cost
- Pools have begun capping block size to drive up transaction fees. Bitcoin transaction processing rate may be unable to keep up with growth in transactions from new users. Bitcoin is becoming unusable for micro-transactions.
- Every month more mining power is concentrated in the hands of a smaller number of people
- Mining ensures majority of new crypto-coins go to people with botnets, GPU farms and ASICs not available to the public.
- No one benefits from mining except miners and electricity companies
- Electricity used by mining is wasted. Money spent on mining is being thrown into a hole, burnt and the costs are passed on to every Bitcoin holder
- Mining will substantially increase transaction fees to unsustainable levels when block rewards decrease. Bitcoin transaction fees may reach a level higher than the banking system Bitcoin was created to replace.
- Miners selling newly created Bitcoins to pay equipment and electricity costs, drives down the price of Bitcoin.
- If Bitcoin reaches viability as the next global reserve currency, the incentives for nation states to monopolize and control mining will be too great to contain.
Skycoin was designed to eliminate mining completely and eliminate the problems it creates. Skycoin replaces reliance on honest miners with reliance on mathematics.
- Skycoin is more secure because it does not rely upon the good will of miners
- Skycoin transactions will be cheaper because there are no mining costs being passed on to users
- Skycoin transactions are not subject to 51% attacks by mining cartels
- Skycoin is environmentally friendly and sustainable. Skycoin does not require twelve coal power plants to power mining
Distribution will be as fair as possible.

These are some things we are working on.
Off Blockchain Transactions:
You can send and receive coins, instantly, with ~120 bytes of overhead, without cluttering the blockchain. Skycoin supports a secure, standardized interface for transmitting and receiving coins (and other assets) held by third parties.
You will be able to see, withdraw to the blockchain and transmit coins held by third parties, from within the Skycoin wallet. This protocol automates withdrawing and depositing assets into exchange accounts and enables bandwidth micro-transactions.
CoinJoin RFC:
- Skycoin naively supports a simplified CoinJoin protocol
- CoinJoin mixes transactions from multiple wallets to increase transaction privacy
- Skycoin is designed so that it is impossible to determine which transactions are CoinJoin transactions
Skycoin Coin Join Protocol:
- Three people send their inputs and outputs to a remote server
- Server creates a transaction containing the inputs/outputs from all three people
- The server sends each person the transaction.
- Each person verifies the transactions and sends the signatures for their inputs
- The server publishes the transactions.
This protocol is much simpler than zero coin while dramatically improving transaction privacy.
Wallet Shuffle RFC:
Shuffle provides a very easy way of moving coins between deterministic wallets. Shuffle is one of the ways Skycoin will improve wallet usability.
Wallet shuffle takes a seed for an existing deterministic wallet and seed for a new deterministic wallet and moves coins between the wallets using the Money Pot protocol. Every shuffle operation entails additional coin mixing and increased wallet privacy.
For instance,
Input wallet: 5a42c0643bdb465d90bf673b99c14f5fa02db71513249d904573d2b8b63d353d
Output wallet: 1d26c392b3c1b6c5c7947e07934d8256bdf084bcf89f58d82ebef3c986e4836c

Summary
Skycoin is a third generation cryptocurrency. The Skycoin project is a long term infrastructure project that began around the time Litecoin was launched. Skycoin is designed a successor to Bitcoin.
Skycoin is focused on implementing Satoshi's original vision for a cryptocurrency. Satoshi originally intended the Bitcoin network to be decentralized, over hundreds of thousands of computers. Today, the Bitcoin network is completely controlled by three mining pools. Bitcoin is no longer decentralized. Skycoin Project has developed a new consensus algorithm to achieve true decentralization.
In addition to fixing the outstanding technical issues with Bitcoin, the Skycoin Project is implementing a new next generation of foundational networking, storage and application primitives (a new internet). We believe that "blockchain" is just one of several new mathematical and algorithmic primitives, which will underly the foundation of the successor to the current internet.
- CX is the Skycoin Project's computation primitive (analogous to EVM, Solidity, Go, C/C++, Rust)
- CXO is the Skycoin Project's peer-to-peer immutable data storage and replication primitive (analogous to IPFS)
- Skywire is the Skycoin Project's communication primitive (analogous to MPLS, open-flow, TOX, mesh networking, darknet, i2p)
- "Skycoin" is the Skycoin Project's blockchain primitive, token and transaction infrastructure (analogous to Bitcoin, Ethereum, etc)
The Skycoin Project is not a simple blockchain project, but is designed as a platform and foundation infrastructure for supporting an ecosystem of applications.
=== Skycoin (SKY) ===
The Skycoin Project Coin (SKY) is focused on core features, security, usability and simplifying Bitcoin instead of adding features as a marketing gimmick.
There are still major outstanding problems with Bitcoin and those are the problems we are addressing.
- Elimination of the need for miners for network consensus through new algorithms, elimination of dependence on the human element in the network operation
- Duplicate coinbase outputs
- Signature malleability
- Reduction in complexity in implementation
- Dozens of security/crypto related improvements
- Elimination of external dependencies that create security concerns in Bitcoin
- 51% attack proof and strengthening against various attacks
- Simplified, more powerful data, transaction and wallet APIs
- Brainwallet, deterministic wallets as default
- Network security improvements
- Intrinsic support for gmaxwell's CoinJoin transaction privacy protocol
- New networking protocols to enable the verification of the mathematical prerequisites for consensus network convergence
- Separation of coin creation from the consensus network, to eliminate Bitcoin's tendencies towards mining centralization
- Directed bipartite TX/UTXO transaction graph structure which is more elegant and efficient than Bitcoin's multi-graph structure
- Provably upper bounded network, RAM and CPU resource usage for network operation
- Soft coded, adjustable blockchain size parameter to enable network transaction rate scaling
- Rolling unspent output state error correction coding in the block header for early detection of software/hardware non-determinism
- Blockchain/transaction/histrory storage database with constant time lookup, indexless operation for all major blockchain history queries
- Etc...
Skycoin is 51% attack proof and addresses many of the security issues in Bitcoin. Skycoin is designed to be a simpler, easier to use, more secure Bitcoin. Skycoin emphasizes simplicity, security and usability.
Skycoin is a major research undertaking and has taken several years. We are finishing up phase one of project implementation and then focusing on services and driving adaption.
Skycoin is being developed in collaboration between AKS, Myth and Syndicate under Darknet Plan and OP Redecentralize.

Obelisk is what makes Skycoin "Bitcoin 2.0". Obelisk is a sustainable alternative to proof-of-work. Obelisk is a system that replaces proof of work for blockchain consensus and eliminates the possibility of a 51% attack.
Obelisk was inspired by academic research into adversarial distributed time-stamping and algorithms such as Ben-Or's, Paxos, and the Castro-Liskov PBFT algorithm. Obelisk is a new solution to the Byzantine Generals problem which offers strong mathematical security guarantees, even when the majority of nodes are hostile.

Skycoin cannot be 51% attacked. No matter how much money or hashing power an adversary has, they cannot reverse transactions.
Skycoin Transactions are fast. Obelisk and specific design decisions may allow Skycoin to achieve transaction confirmation times as low as four seconds, without compromising security.
Skycoin does not waste electricity or consume exponentially growing, unsustainable amounts of electricity unlike Bitcoin.
Skycoin has no transaction fees. Users receive "coinhours" for holding coins, which are used for paying transaction fees. Transactions bid to enter a fixed sized block.
Skycoin transactions offer increased privacy. Skycoin is designed for advanced CoinJoin support.

Besides building a better, more robust, most secure, more usable Bitcoin, the Skycoin project is working towards several long term goals we believe are necessary.
Skycoin Darknet Project:
- Users receive Skycoin for contributing resources to network and expend skycoin for consuming resources
- Almost as secure as TOR/I2P, but with much high bandwidth throughput.
- Very difficult for ISPs to identify and throttle
- Inspired by cjdns
See: https://github.com/skycoin/darknet
Skycoin Meshnet Project:
- Uses Skycoin Darknet protocol over wifi mesh network
- Uses receive Skycoin for providing transit
- bridge the "last mile" between homes and fiber with a distributed wireless mesh networks and community ISPs.
- SOPA, PIPA, ACTA and the Comcast/Time Warner merger have made it clear that political solutions are no longer viable.
---
Development Process:
All Skycoin components are written in Go (Golang). There are multiple teams working on Skycoin and multiple independent software components required to achieve the long term vision of the project. This is an open source project.
Substantial coins are reserved and available for developers who want to contribute to the project.

Design:
Skycoin tries to offer more security, greater privacy and better usability than Bitcoin.
Skycoin Philosophy:
- Complex systems cannot be secure
- Simplicity over complexity
- Decentralized but pragmatic
- Emphasis on usability
----
Partial feature list:
Security:
- Higher level of security for non-technical users with improved ease of use
- Deterministic ECDSA, enforced signature mutability
- Hardening against SHA256 pre-image attacks, hardening against side channel attacks
- Hardening against "offline" attacks on secp256k1
- Optional quantum computer resistant TwoStep protocol transactions
- Standardized remote signature HMAC API for hardware wallet devices
Privacy:
- Skycoin transactions have higher privacy than Bitcoin transactions ("wallet mixing", "money pot")
- Skycoin protects its users from identification for increased safety in hostile countries (ex. HTTPS/TLS tunneling)
- Stenographic wallets
Usability:
- Wallet supports Bitcoin and Skycoin
- 15 second transactions (point-of-sale)
- Simple 256-bit deterministic wallets
- Clients only need unspent output set instead of whole block chain ("Snapshot")
- Coins divisible to 6 places
Distributed Exchange:
- Off blockchain Transactions (through standardized API, "gateway")
- Powerful scripting language for contracts (non-turing complete statically typed LISP variant)
- Open Transactions type crypto-equities, bonds, options and other securities
- OTC gateway API (based upon FIX, SWIFT, FIXatdl)
The blockchain is for settlement between counterparties. Price data and bid/ask orderbook data is not in the blockchain, but supported through the gateway API. Fractional Skycoin transactions and micropayment are handled as off block chain transactions.

No Mining:
Satoshi has stated that mining is Bitcoin's only flaw. Miners are the greatest non-crpytographic threat to Bitcoin retaining value on geographic time scales. Mining introduce human factors and greed into the survivability of Bitcoin as a currency
- Dishonest miners may destroy Bitcoin
- We are close to a 51% attack
- gigahash.io has abused its hashing power to steal Bitcoin from gambling sites
- Services such as cex.io allow people to rent a 51% attack by the minute
- Mining pools will form cartels to orphan blocks mined by non-cartel members, to enhance their block rewards
- Mining cartels will rent capacity to orphan blocks from other pools, if the reward is greater than the cost
- Pools have begun capping block size to drive up transaction fees. Bitcoin transaction processing rate may be unable to keep up with growth in transactions from new users. Bitcoin is becoming unusable for micro-transactions.
- Every month more mining power is concentrated in the hands of a smaller number of people
- Mining ensures majority of new crypto-coins go to people with botnets, GPU farms and ASICs not available to the public.
- No one benefits from mining except miners and electricity companies
- Electricity used by mining is wasted. Money spent on mining is being thrown into a hole, burnt and the costs are passed on to every Bitcoin holder
- Mining will substantially increase transaction fees to unsustainable levels when block rewards decrease. Bitcoin transaction fees may reach a level higher than the banking system Bitcoin was created to replace.
- Miners selling newly created Bitcoins to pay equipment and electricity costs, drives down the price of Bitcoin.
- If Bitcoin reaches viability as the next global reserve currency, the incentives for nation states to monopolize and control mining will be too great to contain.
Skycoin was designed to eliminate mining completely and eliminate the problems it creates. Skycoin replaces reliance on honest miners with reliance on mathematics.
- Skycoin is more secure because it does not rely upon the good will of miners
- Skycoin transactions will be cheaper because there are no mining costs being passed on to users
- Skycoin transactions are not subject to 51% attacks by mining cartels
- Skycoin is environmentally friendly and sustainable. Skycoin does not require twelve coal power plants to power mining
Distribution will be as fair as possible.

These are some things we are working on.
Off Blockchain Transactions:
You can send and receive coins, instantly, with ~120 bytes of overhead, without cluttering the blockchain. Skycoin supports a secure, standardized interface for transmitting and receiving coins (and other assets) held by third parties.
You will be able to see, withdraw to the blockchain and transmit coins held by third parties, from within the Skycoin wallet. This protocol automates withdrawing and depositing assets into exchange accounts and enables bandwidth micro-transactions.
CoinJoin RFC:
- Skycoin naively supports a simplified CoinJoin protocol
- CoinJoin mixes transactions from multiple wallets to increase transaction privacy
- Skycoin is designed so that it is impossible to determine which transactions are CoinJoin transactions
Skycoin Coin Join Protocol:
- Three people send their inputs and outputs to a remote server
- Server creates a transaction containing the inputs/outputs from all three people
- The server sends each person the transaction.
- Each person verifies the transactions and sends the signatures for their inputs
- The server publishes the transactions.
This protocol is much simpler than zero coin while dramatically improving transaction privacy.
Wallet Shuffle RFC:
Shuffle provides a very easy way of moving coins between deterministic wallets. Shuffle is one of the ways Skycoin will improve wallet usability.
Wallet shuffle takes a seed for an existing deterministic wallet and seed for a new deterministic wallet and moves coins between the wallets using the Money Pot protocol. Every shuffle operation entails additional coin mixing and increased wallet privacy.

Input wallet: 5a42c0643bdb465d90bf673b99c14f5fa02db71513249d904573d2b8b63d353d
Output wallet: 1d26c392b3c1b6c5c7947e07934d8256bdf084bcf89f58d82ebef3c986e4836c
This account is for the Skycoin Foundation. We are coalition of Bitcoin stakeholders funding development projects to improve Bitcoin security and privacy.
The Skycoin foundation is involved in open source projects related to
- Post Proof-of-Work block chain security (secure alternatives to proof-of-work)
- wallet security (hardware wallets)
- transport layer security (reducing ability to identify Bitcoin users from IP data)
We will be announcing a new alt-coin soon, which is the first provably secure coin that is not based upon Proof Of Work.

There are still many challenges to be resolved by the community.
Miner cartels are becoming greater threat than 51% attack. Miners need 2 million dollars a day to pay electricity bill. When block rewards decrease miners need higher fees. Miners cant make money unless they reject low fee transactions.
Some of the greatest problems facing Bitcoin
- Governments can determine who is using Bitcoin from IP data. Some governments do not want citizens to have access to technologies like Bitcoin. The identities of the people running the Bitcoin client are not protected.
- Bitcoin only supports 8 transactions/second and Visa's network clears 2,000 transactions/second
- Bitcoin transactions are too easy to track. Bitcoin does not offer the privacy required for widespread use in many countries.
These problems are being worked on.
