Devv (build by the company Devvio Inc.) claims to be the world’s fastest blockchain (over 8 million transactions per second) and addresses to solve all today’s major blockchain challenges.


Instead of only focusing on a single kind of problem (e.g. scalability), Devv is addressing all of today’s blockchain challenges: Governance, Scalability, Volatility, Cost, Transaction Fees, Privacy, Immediacy, Energy Usage, Issuances, Fraud, Theft & Loss


Devvio creates a long-term governance model which includes three groups (each group will have equal voting power):

Different kind of proposals require different majorities and parties to agree (examples can be found in the Bluepaper).


Devv’s scalability is implemented through a multi-tier blockchain approach. It is based on a system where there is one Tier 1 Blockchain (T1) and many Tier 2 Blockchains (T2). The T2 networks are shards. T1 and T2 are comprised of independent nodes. The blockchains comprising T1 and each T2 comprise the entire Devv blockchain implementation.

The T1 blockchain controls the primary Devv blockchain, has a longer block time and a larger block size than the T2 blockchains. T2 blockchains validate and transmit only a subset of outgoing transactions and transmits those transactions to the T1 blockchain over time.

The extreme high throughput is achieved by combining the output of those T2 blockchains in another separate blockchain.

“Devv’s scaling capabilities derive from a multi-tier sharding approach where many independent Tier 2 (T2) blockchains (shards) record outgoing transactions for their designated wallets and a master record is maintained on the Tier 1 (T1) blockchain.” — Source: Whitepaper p. 14

8 million transactions per second benchmark


Devvio argues the main purpose of blockchains is to maintain asset balances and therefore processing/computation should be done off-chain, only updates to the balances should be stored on-chain to provide a robust, trustless and transparent system.

“As of Q1 2018, to add two numbers together 1 million times, it costs over $20 in gas with Ethereum. On an AWS server, it costs on the order of $0.00000007. That is 9 orders of magnitude more expensive” — Source: Bluepaper p. 35

Transaction Fees

Devv does not innately need to charge transaction fees. Devvio may charge a small fee like Ripple does to avoid spam or DoS attacks. These potential fees can vary on network load.


Basically Devv provides a publicly available blockchain with pseudo anonymous privacy, which is the same as for blockchains like Bitcoin or Ethereum.

In addition Devv has an optional methodology for private transactions in cases where it is wanted. The methodology is trust-based and it is implemented via the INN. A user who wants to send a private transaction has to send Devvnero to an privacy account of Devvio and send an off-chain encrypted message to the INN containing the target wallet. Subsequently the INN creates a transaction on the Devv network containing the correct amount and target wallet address. This enables transactions that are private to the public but also compliant with government laws (KYC, AML, …).

Immediate Node Network (INN)

The Immediate Node Network (INN) is operated by Devvio Inc. and represents a trust-based network. It is built on top of the multi-tier network and allows instant transactions below one second. In addition to that the INN enables fraud/theft protection, loss prevention and private transactions. The INN uses a secondary cryptocurrency which will be called Devvnero.

T1, T2 & INN network layout


Devv will utilize a specific, secondary type of cryptocurrency class called Devvnero to enable more protections on transfers. No user is ever required to send a transaction in the form of Devvnero as it is a completely optional feature of Devv; however, the use of Devvnero can provide valuable protections based on trust of Devvio (in the same way that people trust credit card companies to protect their interests when making online purchases). An account with Devvio is required to use Devvnero, so that its protections can be verified (KYC required).


The Devv protocol has the ability to ensure stability through a concept called DevvFiat, a nonvolatile one-to-one fiat backed representation of a currency. This is accomplished through the use of the “Dallocation” (Devvnero Allocation). Amounts that are transferred into a Dallocation by a user can be converted through an exchange mechanism into DevvFiat. DevvFiat can take a number of forms such as DevvDollars or DevvEuros, for example. For every DevvDollar that is issued by Devvio, as an example, one US Dollar will be put into an escrow account controlled by Devvio. The escrow account will be audited, and can be publicly verified as to its integrity from the beginning.

DevvFiat can also be used to wrap other assets. A Dallocation can contain DevvBitcoin, DevvEther, or even DevvGold. A Dallocation can also contain DevvBaskets that represent 12 groupings of fiat currencies and other financial instruments which can have even less volatility than the US Dollar.


The Dallocation sets aside Devv, DevvFiat, or other tokens to be verified immediately by the INN. The Dallocation can be utilized for immediate transactions and represents Devv held in the user’s wallet that the INN can transfer through its payment channels based on a user’s actions (such as a credit card purchase or mobile app purchase). A user can send an encrypted originating message in order to create the Dallocation for a Devvnero Wallet, along with an indication of the INN’s permissions for sending Devv from the Dallocation. Those transactions do not utilize the private key for the Devvnero Wallet, but instead nodes on the INN use their own private keys to create transactions that can be validated by T2’s. Devvio can therefore allow the ability to guarantee payments immediately.

Energy Usage

Devv uses Proof-of-Validation for its consensus mechanism, where validators (which are the consensus providers) create blocks comprised of transactions, and then collectively validate each block by sending validation messages.

Consensus: Proof-of-Validation


Devvio will have a different philosophy on rewarding validators. Validators will only receive a fair amount of tokens which will be comparable to other cloud services, but compared to other blockchains the validators won’t receive a big stake for doing validations.

Fraud, Theft & Loss

Devvio implements its fraud, theft, and loss solutions with an escrow-like functionality. Only Devvnero wallets have those features, normal Devv wallets do not.


Devvnero wallets have an escrow like functionality implemented. That means if someone sends funds to another wallet, these funds are in an escrow for a certain period of time (pre-defined by the user) before the recipient can access them. An user can have multiple Devvnero wallets with different escrow times. Wallets can also have a whitelist of destination addresses where sending the funds will have no delay (no escrow).

As long as the funds are in the escrow, the owner of the sender wallet can contact Devvio to reverse the transaction. To do so he must prove ownership of the wallet via KYC (Devvnero wallets are always linked to a KYC).


If private keys to Devvnero wallets get lost, Devvio can also be contacted and private keys restored (after ownership verification). Private keys of normal Devv wallets can not be recovered (same as e.g. Bitcoin).

Smart Contract Philosophy

Given that the Devv blockchain is used to represent digital representations of value, and is intended to implement trustless transactions in a robust way, the implementation of smart contracts is designed simply to improve capabilities in representing those digital assets. Smart contracts, in the Devv protocol, are implemented either as part of the core protocol itself, or in the form of Smart Coins (linked together) which provide added functionality.

Smart Coins

Smart Coins represent other types of ownership and identity beyond Devv itself as well as implementations for on-chain processing and operations.

Basic roadmap


Token Allocation




Devvio wants to fix all issues of the blockchain in a single solution. Their goals are extremely ambitious and it’s very difficult to say if they can deliver on their promises or not. They certainly have unique and innovative approaches to tackle those problems (scalability, privacy, fraud/theft/loss, …).

If the team can really deliver their objectives, they might be able compete with other large players like NEO, Cardano, Ripple and EOS.

It’s definitely worth reading the paper(s), features and tech are explained very well and in-depth.
